[Q] Android Market stuck on Starting Download

I have tried several different 2.2 builds on my (AT&T) HTC Pure. Most of what is supposed to work does, and it's fun to play with. However, what's really holding me back is an inability to download anything from the Android Maket. I can sign-in and browse just fine, but when I "Install" something and go to the downloads tab, all I find are apps that say "Starting Download" with a perpetually cycling progress bar. I've let it run for 15 minutes and never got anything to actually download. I do not have a data-plan, so I use wifi. I have verified that wifi works.
I have also noticed that I cannot sign into gTalk. I've seen several posts suggesting that once you sign into gTalk, that I'd be able to download apps (and vice-versa), but so far, neither of these applications/features is working for me.
The latest install I've tried is XDANDROID.2.2.AOSP.FRX01.17.09.10.UPDATE_PACKAGE.7z and it still has this problem.
Has anybody else gotten around this problem and have some advice???
I tried using my phone to create a new google account, and that worked, but I still couldn't download.

Happened to me as well. I just forgot about it, and after a while I got an alert that one of the apps is now installed (and indeed working). The other apps on the list hanged as well, and took a lot of time to start downloading.
Seems like a nasty bug to me.

it's a small comfort to know I'm not alone, but I still haven't seen anything download successfully, and as long as I can't install new apps (from the market), there's really no point in using [XD]Android.

Try settings/applications/manage applications/market 'all tab' and force stop. Clear cache. Clear data. So next time you use market it is like new and downloads and installs without hanging etc. Your downloads tab should still have a record of apps you downloaded.

thanks anunna, but that didn't work. I tried downloading the apks for App Brain and the associated "Fast Web Installer" and copying to my device (storage card), but that doesn't seem to work any better. I guess those apps still depend on Android Market to download.

aarrrrrghh. so frustrating... I have now installed Rhod.2.2BLAZN.092610 with the new builds from 9/25 (hw 3d included), and still have this problem. Does anybody have any ideas?? I dont' see how this could be device-specific. ?? I've tried different gmail accounts, different builds, and different wifi networks. The only thing I haven't tried (and can't really) is accessing market over 3G. I say "can't" because I actually have a data-block on my phone to prevent unintentional use and associated charges.
Does anybody have any advice for troubleshooting ?
thanks.

BTW, this is what worries me about WP7: one source for all your apps = single point of failure.

I'll just keep updating my own thread here...
Installed the latest build from 9/28, and nothing's changed.
This time, I went straight into Google Talk and got stuck on the "signing in" screen. Eventually it came back with a message stating, "Could not connect to server. Will retry shortly." This is bogus though, since I can do nearly everything else on the internet, via my wifi connection.

I have the same problem. Android Market doesn't download any software, "Starting Download..." stage never ends...

ashway, have you tried opening Google Talk? Also, do you have a data plan on your phone (3G)?

I haven't try Google Talk yet, will try later. I do have a data plan, do you mean that Market works via 3G and doesn't through WiFi?

I have a data-block on my phone (so I don't accidentally rack up per Kb charges), so I access everything via WiFi. I've seen people suggesting that toggling between wifi or cellular can get it to work, but that's not an option fo me.

(thanks for your update though)
Has anybody been able to download from A.M. over WiFi without ever using 3g?

It just happened to me while i'm updating a few apps. I did some research and found an article and follow that way. what you need to do is to un-install the app that you're updating. after that, forced close the Market app and clear the cache. then try again to install it from market. well, it works for me.
by the way, there's also another bug that make Market FC every time when u download an app. if it happen to you, just open Setting>Applications>Manage Application> Market and click "Uninstall Updates".

I am in Malaysia and I have this problem too. It is either "Starting Download...", "Download Unsuccessful" or "Download Paused" message.
I'd tried both 3G (3 different telcos; Vodafone while in NZ, Optus while in AU and Maxis in MY)and WiFi (different AP; at least 10). While connected, I can do everything except for download apps from Market. Also tried signing in different Gmail account.
Being desperate, I tried to install Apps via "adb install" command. Guess what, I couldn't uninstall my apps (both using "adb uninstall" and "Settings > Application > AppName > Uninstall"). It force close everytime I tried.
I got OTA updates for FRG83 twice hoping it will fix my Market problem, but it did not install because it can't. When I tried sdcard:update.zip, I got status 7 error. Some livewallpaperspicker.odex error. Tried searching for the odex but couldn't find one specifically for Nexus One.
Also tried rooting my phone and install ROM Manager. Performed a Fix Permission issue (which it claims often fix Force Close message; one friend recommended this too) and all I got is "An error occurred while attempting to run privellege...". I am sure it is rooted with Superuser Permissions showing "Allow" status. To confirm, I had Move2SD installed and able to port most apps to SD without the developer setting the option.
Just want to share this with all of you that have this problem. Is there anyone can help? The only thing that makes me keep this phone is because its a gift from my wife. Or else I would just get something else.

guys I have the same problem as you do! something I noticed though is that the phone doesnot recognise my SD card and market is downloading the apps on the card . can you pls check your sd card if they are mounted and recognized propperly!

restarting the phone and letting the card mount propperly fixed the adnroid market download freeze issue

brafun, are you using XDAndroid on a TD2/Pure? Were you experiencing problems only when using wifi? do you have a cellular data plan/connection? Does wifi download work now? I'm a bit confused, since XDAndroid is installed on my SD, I don't see how you can have Android running without recognizing it.
thanks

Your guess is as good as mine but the fact is that when I was trying to download an app the behaviour was exactly the same as you described it! It said Starting Download and froze at that point. Cleaning the Cache of market didnt help at all. THen I just started looking for reasons why is this happening, and in "SD card and phone storage" I saw that the SD card was marked as not mounted... check yours and see what it says

No Data after flashing roms, this is probably a stupid question...

Okay so over the past few days I've been flashing a bunch of diff roms to see what I like. I've had a constant problem with getting mms to work on any of them. Well I was doing all of this from home and always had wireless to use for data, hence I used it.
Tonight, however, after flashing a few diff roms I found out I didn't have a data connection at all. Tried a couple diff cm6 nightlies and the blackmod of cm6, and after flashing the only way I can access the internet is through wi fi. Otherwise I got nothing.
Sooo, maybe my mms problem was just this all along or maybe not. Anyway, what could be the cause of losing all data connectivity. Phone says it's connected in status. And the widgets somehow magically update. But the browser, market,mms, etc don't work at all.
I'm gonna flash the 0.7 aospmod and see what happens. Any help you can offer is appreciated.
And yes, I might just be an idiot. Forgive me.

Just flashed aospmod v.07 and same ****. No data connectivity.
What gives? I feel stupid.

a guess
possible APN settings issue, did you flash back to a 2.1 sense rom, and try an Over The Air activation and update profile?
I honestly don't know but thats a guess... I use my phone with pageplus (verizon) and editing my APN settings is what fixed it for me.

Ruu. Started fresh.
Everything seems to be okay.
Thanks.

This happens on a lot of roms. I've found to fix it all u have to do is toggle on and off either or both airplane mode and moblie network.

I found having to open browser and put in my cell number b4 sprint data would work, also prl update works for me.

I had this happen to me (including all bars showing and things refreshing) and spent several hours working on it only to determine the only solution was to RUU and start over....but its faster this time around because you have nandroids....just flash one after you re root from before you lost data (if you have one) and if not, back up your apps and data with titanium backup or mybackup pro...
(I had tried all the things listed in the previous posts....not saying they wont work for you, but in my case, they didn't)

[Q] Market killing 3G connection

I have a weird problem with my AT&T galaxy tab. For the past couple of days, each time I launch the Market, my 3G connection is killed and I can no longer access the network, and of course I cannot access the market. As soon as I kill the market app, my 3G connection comes back.
I cleared the data and cache of the market app, did not solve the issue. When I uninstall the updates of the market app (reverting to the original ugly market app), everything works fine, but it then automatically updates itself and the problem comes back. I assume this is a problem with the market app itself and not my device (hopefully).
Has anybody else experienced this issue and found a fix?
I am running stock ROM with third party apps installed enables (done it with superoneclick: root, enable third party apps, unroot).
I have the amazon app store installed, so I can still buy new apps, but I would like to be able to get updates for the apps I have purchased from the market.
Any help would be greatly appreciated.
Thanks!

What modem are you using? Does the problem happen when you are using wifi? I think the JMF modem that is available for overcome rom is weak and I get many dropped connections and slow data speeds.

I am using the stock ROM and stock modem, I have never flashed a ROM. It only happens with the Market App.

Same issue for me. I have a rooted stock rom.

I have the same issue. Also stock rom and rooted. When WIFI is on (and connected) the market works fine.

I have been beating my head against this since I bought one. I am rooted using....I think I used Super One Click......stock everything else with non-market apps enabled. I originally thought that Root had broken it; however, if I unrooted, reset to factory, I still had the issue.
After many hours at the ATT store and on the phone (and swapping the device once and SIM card twice) I had an epiphany. a Factory Reset does NOT wipe the Internal SD like I thought it did. It leaves /mnt/sdcard/ intact. So, just for kicks, I began looking at my folders here. I MAY have discovered something. Market started working after I restored this folder to it's factory content (deleted any folders having to do with Apps in general).
I can typically hold power, deactivate Data connection, wait a few seconds, re-enable, and I get 3g back (at least for browser and other apps, Market still fails).
I have PSX4Droid installed (PSX Emulator if you don't know). There is a folder here named /.psx4droid, so I renamed it to /psx4droid (If I remember correctly, doesn't the "." hide the folder......too long since Linux class). I then deactivated/reactivated my data, and the Market started working properly.
I am not sure if it has to do SPECIFICALLY with psx4droid or just the "Hidden" folder in general, but now my Market works. I have 2 more folders in this location (/.downloadTemp and /.FileExpert) that may/may not cause any problems. I will post my findings.
.....Okay, so I'm going to type what I write now....Market just failed. Now I'm renaming /.FileExpert....Let's see what happens......
Damn. Still fails. But I'm tellin' ya. There is something in this folder causing it.
Or maybe some app is causing it to break......I have Amazon App store installed, what about you guys?

I do have Amazon App installed.
Anybody with an AT&T Tab not having the issue?

Same issue here. I had the Amazon Appstore installed but uninstalled it probably a week afterwards. Rooted running stock, everytime I go into the market it crashes the 3g. I found a folder in sdcard/android/data that had a bunch of appstore files in it. I deleted that and still having the same issue. I have removed all 3rd party apps so I have no idea what is triggering this. Please help.
P.S. I can access the market on WiFi

This also happens to be sometimes, if you tap wifi on then off again your 3g should come back and work fine.
swyped from a galaxy far far away...

Unfortunately what you proposed did not work. The market is killing the network connection each and every time. The network connection only comes back when the market app is not active anymore.
Since everything works fine when the market upgrades are uninstalled, I really think it is a bug in the newer version of market. Hopefully, the next update will fix this.
Maybe when Gingerbread is out!

I'm thinking this has more to do with us having installed amazon appstore before it was supposed to be. Somebody is mad at us

Has anyone made any progress on this situation?
Sent from my SGH-I987 using XDA App

I really wish I would have made more progress. After all the trouble I had with the device with this issue, I was seriously monitoring the apps I installed and then testing the Market. I gave up after a while since I am on Wifi 90% of the time and hardly ever do I access the Market while driving. I still have a feeling that something in /mnt/sdcard is causing it. Like I had mentioned, I could wipe back to factory and the problem was still there. I seem to remember that it only started working proper after I had cleared this location of crap. I would think that a Market update would see a larger group of affected tabs than just a handful of us. This doesn't seem to be a widespread issue.
That being said......I have decided to move on to Gingerbread. Maybe that'll fix it

Hey guys, try this. Worked for me and my Data problems with Gingerbread
http://forum.xda-developers.com/showpost.php?p=13751694&postcount=6
Basically create a new APN inside Settings -> Wireless and Networks -> Mobile Networks -> Access Point Names. Only set the APN to "Broadband," save it (Menu button) and select the radio button for it. Instantly fixed my data issues.

Thank for the tip. Unfortunately, it did not work for me. I am running stock 2.2 and waiting for the official 2.3 update from AT&T.

Good Luck. I thought about waiting for the official.....but I also have a Captivate. We didn't get 2.2 until MONTHS after the rest of the world (I think it was like 5 or 6 months later). I didn't want to wait that long again.

Could you please report if the problem fixed with Gingerbread ?

At first I didn't have ANY cellular data until I created a new APN mentioned in the tagged thread (APN Broadband). Now I have no issues with Market. I wish I could trust AT&T to release Gingerbread in a timely fashion, but I know better. So instead, I flashed Overcome.
P.S. I really can't enough of the CRT lock animation......damn I'm such a geek....

[Q] Tab updates service providers?

Geez, I read the sticky in General and still ended up putting a question there. Sheesh. Apologies.
So, I have an original i987 ATT GTab 7 that I somehow got to GB a year or so ago, but it doesn't save settings consistently, loses my xfinity and yahoo mail account info, doesn't run half the apps I had under Froyo, and has some residual Skype config stuff from install on Froyo that won't let me install or run Skype anymore. Also, the wifi stack has always been sketchy. I also unlocked the Tab and managed to run it on another provider in China. I tried to root recently with SuperOneClick 2.3.3 and it pops up a window "SuperOneClick has stopped working..." I know how to set to USB debug and used Sideloader until ATT finally opened up the markets. I tried reloading the drivers and still get an exclamation mark.
The question is: does anyone do upgrades for a fee?
What I'm looking for is to enable the dialer, get the best wifi stability, have 3g data, the newest stable OS, have my apps run and be able to use it on ATT and Straight Talk (got the SIM already) for data, voice, and messaging.

I can recommended overcome method (see my signature for links)
With at&t stock modem and correct APN, you can go all the way to jellybeans if you want, and gel 3g and dialer.
The actual dialing though, is a problem. At&t knows you are a tablet, from their list of IMEI, and you likely can't dial on tablet plan.

So, will the Overcome 7 wipe give me a functional dialer (assuming the provider allows a call), or do I need to load the wifi fix or stock theme version? And what do those do differently from the wipe version?
Thanks,
Dan

No need those.
wifi fix is for those who has issue of wifi disconnecting.
stock theme version is for those who want it to look like Samsung stock.
Yes, if the provider allows making call, it will work fine.
I guess I didn't read your initial problem properly.
But tab not saving settings properly or can't get rid of old info, is a sign of internal nand chip going bad...
If that is so, you will have more problem ahead of you.
Hope it isn't the case.

Oh, great. Well, it's all done now, apparently successfully, just need to go to Straight Talk.
So, this NAND chip. Any chance reflowing the board will fix it, or is it the chip itself? guess I could change the chip, unless it is a BGA.

It is just the chip,
there are two threads in the general forum I think that deals with damaged internal sd and how to use external only.

No talk about replacement so far. It is a Sandisk chip.
It will be great if you know how to get the replacement, I am sure many here are now running without one after removing it.

Well, at least on mine, the Overcome seems to have fixed the issue there, in addition to running much that so far. So, is this the latest? You have really gotten behind Overcome, but what about Cyanogen or others? Seems Overcome is based on Gingerbread, or is it ICS? Just need to get Straight Talk going and see if I can dial.
Is there a donation fund for Overcome?

It is GB based.
teamovercome website is down for so long, I wonder if they are still around as a group.
You can easily move on to ICS and JB of CM/AOKP
Just download the ROM and the correct gapps for it
and put in SD card
and boot to CWM recovery and flash it.
Watch the message on the screen.
Too many people saying it is bootlooping while actually each flash produce a different message as it progress with the process.

Problem accessing Youtube and Play Store

Hi, I desperately need some support as my device refuses to sign in in both Youtube and Play Store. I'm therefore unable to use both these apps. An error message keeps saying I'm offline and proposes to retry, but it simply never works whatever I do.
Issue has been going on since many weeks; I googles and tried many suggestions without any success.
Before I do a hard reset, has anyone an idea what this can be?
The amazing part is that my daughter's tab (Galaxy S2) is also having the same issue since some time! She has her own google account. What the heck is going on?
Thanks!

This may be an bug in the updated version of google play store or YouTube..Have you tried to sign in specific apps usning another google account you have..Also try to clear cached data of phone as well as clear data of those apps* you can also uninstall updates of those apps and force stop or disable them and after enabling again try to access*..Also might be network related issue sometimes weaken network shows such type of errors..Try to acees with high speed wifi or data with maximum signal..Even if problem exist then simply reset is last option for you..

Hi, I tried most of the solutions you're are mentioning, without any success. What I find interesting is what you wrote about weak network. I cancelled my cable connection at home some time back and using instead a 4G modem. Could that really be the culprit, knowing the coverage is medium? It sounds to me strange that such possibility exists, also I often go out and have full 4G network for hours sometimes and still it doesn't work. Interestingly enough, every about once per month it suddenly works, and I'm able to update my apps and also access my account in Youtube. It'll work for 2-3 days, until it's again the same bad. Really boring and would love to understand this issue better so as to possibly fix it. Thank you.

1)It's possible sometimes your networks proxy enforce your google id not to be sign in into specific apps you have mentioned and yes sometimes low network coverage also causes the issues like offline or sign in errors like please check network connection due wireless functionality limitations
2)I am curious about one thing if you have tried almost all the solutions found on google as well as your own, is it that much impossible for you to make backup of your current imp data and give a try to hard reset?? If i am not wrong, please give it a try because sometimes software glitches also causes the app crashes or network errors
3) Next thing sometimes your stock software gets corrupted due to some fatal malwares so many system apps as well as third party apps pretended to show errors like unfortunately process is stopped also some network related issue, so one solution you can try is to re-apply or update your current stock firmware..i.e. if update is unavailable you can fresh install same firmware version again on your phone which most of the times resolves the issue
4) As i mentioned in my first post you should give a try to any high speed mobile network like LTE or 5ghz band Wi-Fi which gives constant access to internet connection which probably help you to figure out exact issue i.e. with modems or connection your using or with your device itseld due to corrupted software
5)Please mention your device model no,country,your mobile network provider information so that it would be easy to figure out your issue

Thank you. Yes, a hard reset could solve it although I'd like to avoid it if possible. I will try ASAP on a solid wifi and see. I forgot to mention an important point: my daughter's tablet (Galaxy S2 pro) has got the same issue, and it started near about the same time like it did to me. She has her own Google ID, and she uses a different set of apps. Will report whenever I can test on a wifi.
My mobile provider is Salt Mobile here in Switzerland, and my Note 5 is a generic one bought in UAE. I run Dr. Ketan rom of about 8 months ago.

1)Ohhhk now i got, i assume you might be using Indian Variant with indian mobile network providers as per your username 'prerna'
so your device might be factory unlocked SM-N920C
2)So you should try on any faster network provider or incase wifi to check if problem is due to weak singal strength or specific with your device software integration
3) And i think you should give a try to dr.ketan's nougat rom which is based on latest nougat firmware which will might help you to overcome your issue as new base,new kernel will help you to get stable connectivity
4)If your running dr.ketans MM 6.0.1 based rom then download latest N5 nougat rom to flash
5)I know u might not new in flashing custom roms ad your running a custom one only from 8 months but once again be sure to enable 'oem unlocking' and 'usb debugging' options from developers option before flashing latest twrp version(Don't worry u can flash dr.ketans rom using any 3.0 twrp version ur running now but if latest version with stability and improvements available for your device then you can install it as per your requirement) if your running old one or before flashing nougat based N5 rom by dr.ketan
