[Q] Nexus One - Blank screen

I am having very strange issues with my Nexus One. It seems to be having issues with later versions of Kernel and recoveries!! I have tried flashing almost all the custom ROM's and it ends up with a blank screen. Nothing gets displayed. But the touchscreen and phone itself works. Because I can get calls and I can see everything using android screencast program on my desktop.
To resolve the issue, I always flash 2.6.35.4_SVS-925mV_CFS_AXI_720p_1113MHz_082710 on top of any ROM I install. This has been the case with every ROM. Trust me, I have tried almost every ROM out there! I was running adb shell bugreport and found the below error (highlighted in bold). Is this what is causing the problem? Any ideas how to resolve it?

May not be the issue but I had some blank screen problems first time I rooted my N1 because I has accidentally flashed an AMOLED only recovery image on my SLCD N1.
Unlikely to be the fault as you sound like you know what you're doing but just in case I thought I'd tell you.

I saw this on another thread somewhere on the forum, someone who had the same problem as you. Now it's not to discourage you but I don't remember finding a solution :/ now that doesn't mean we can't try but unfortunately since you've tried a lot of ROMs the only thing I can think of other than a radio flash would be to try passimg to get back to stock.

Probably it was me!!! I tried installing Gingerbread ROM some time back. It ended up with the same problem. I have been thinking if its really a hardware issue and just use whatever works..

I'm tryng the app on my phone that runs android 4.2.1.
Can anyone help me? :silly:

Anyone can help me?

NullPointerException indicates that one of objects that you're using has null value. You can set breakpoint at the line on which this exceptions happens and inspect values of your objects. To do that, you should run application in Debug mode (a button next to Run).

Ok man, I' ll try later

Thank you, I fixed it. :good: :highfive:

Correct. A object has not yet create but you already call some method of it, system return null pointer

I've already solved the problem

Internet permission denied within com.android.systemui context

Hello,
I'm fairly new to using Xposed. I've used it a couple of times to solve some Android CTF challenges, where its ability to hook into an app is a real benefit.
But now I'm trying to understand it a little bit better. As a simple toy project, I'm considering using Xposed to implement a sort of periodic update for Xposed modules. It's not exactly the most useful mod, but it helps me get a better understanding of the framework.
Based on the development tutorial, I thought I could just implement a naive cron.d over the updateClock() method and fire off an AsyncTask to handle
communication to an external server (a package repo if you will). So far, my code goes like this:
Code:
package com.example.red;
import android.app.AndroidAppHelper;
import android.app.Application;
import android.content.Context;
import android.content.pm.PackageManager;
import android.os.AsyncTask;
import de.robv.android.xposed.IXposedHookLoadPackage;
import de.robv.android.xposed.XC_MethodHook;
import de.robv.android.xposed.XposedBridge;
import de.robv.android.xposed.callbacks.XC_LoadPackage;
import static de.robv.android.xposed.XposedHelpers.findAndHookMethod;
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Calendar;
class UpdateModulesTask extends AsyncTask<Void, Void, Void> {
protected Void doInBackground(Void... voids) {
XposedBridge.log("Updating modules");
try {
Application app = AndroidAppHelper.currentApplication();
Context ctx = app.getApplicationContext();
int res = ctx.checkCallingOrSelfPermission(android.Manifest.permission.INTERNET);
if (res == PackageManager.PERMISSION_DENIED)
XposedBridge.log("No internet");
else
XposedBridge.log("Internet granted");
URL url = new URL("<MY URL>");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setDoOutput(true);
DataOutputStream out = new DataOutputStream(conn.getOutputStream());
out.writeBytes("key=value");
out.flush();
out.close();
int rcode = conn.getResponseCode();
XposedBridge.log("Return code " + String.valueOf(rcode));
if (rcode == 200) {
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line = "";
StringBuilder response = new StringBuilder();
while ((line = in.readLine()) != null) {
response.append(line);
}
in.close();
XposedBridge.log(response.toString());
}
} catch (Exception e) {
XposedBridge.log(e.getMessage());
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
e.printStackTrace(pw);
XposedBridge.log(sw.toString());
}
return null;
}
}
public class Main implements IXposedHookLoadPackage {
public void handleLoadPackage(final XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
XposedBridge.log(lpparam.packageName);
if (lpparam.packageName.equals("com.android.systemui")) {
findAndHookMethod("com.android.systemui.statusbar.policy.Clock", lpparam.classLoader, "updateClock", new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
Calendar now = Calendar.getInstance();
int hour = now.get(Calendar.HOUR_OF_DAY);
XposedBridge.log("Hour is: " + String.valueOf(hour));
if (hour == 11) {
int minute = now.get(Calendar.MINUTE);
XposedBridge.log("Minute is: " + String.valueOf(minute));
if (minute % 2 == 0) { // update modules
new UpdateModulesTask().execute();
}
}
}
});
}
}
}
What Xposed logs, instead, goes like this:

So, from what I understand, com.android.systemui should have the "android.permission.INTERNET" permission, which is also what the "Internet granted" message in the logcat output indicates. I also checked for SELinux violations and it doesn't seem to be the case.
What I'd like to understand is why my hook, called from the context of com.android.systemui (which hold the Internet permission), checks to see if it has the Internet permission (and it does) and then receives a permission denied error when actually attempting make the connection, despite the fact that there is no intervention from SELinux. Am I missing something obvious with regards to the way Xposed works?

Don't know on which Android version you test this but by simply looking at SystemUI manifest of Android 6.0.1
you can clearly see there is no INTERNET permission.
Your "if" statement is confusing you. You should rather use:
Code:
if (res == PackageManager.PERMISSION_GRANTED)
XposedBridge.log("Internet granted");
else
XposedBridge.log("No internet");

Thanks for the reply, C3C076!
Sorry for not mentioning the Android version. I'm running Android 5.0.0 build LRX21T on a Nexus 4, if that is of any use.
I've looked through the manifest for 5.0.0 and indeed, there seems to be no reference to the Internet permission. So I've looked around for some means to grant that permission, and came up with:
Code:
if (lpparam.packageName.equals("android")) {
final Class<?> pmServiceClass = XposedHelpers.findClass("com.android.server.pm.PackageManagerService", lpparam.classLoader);
findAndHookMethod(pmServiceClass, "grantPermissionsLPw", "android.content.pm.PackageParser.Package", boolean.class, String.class, new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
final String pkgname = (String) XposedHelpers.getObjectField(param.args[0], "packageName");
XposedBridge.log("Called for package: " + pkgname);
if (pkgname.equals("com.android.systemui")) {
Object extras = XposedHelpers.getObjectField(param.args[0], "mExtras");
Object sharedUser = XposedHelpers.getObjectField(extras, "sharedUser");
Set<String> grantedPerms = (Set<String>) XposedHelpers.getObjectField(sharedUser != null ? sharedUser :extras, "grantedPermissions");
Object settings = XposedHelpers.getObjectField(param.thisObject, "mSettings");
Object permissions = XposedHelpers.getObjectField(settings, "mPermissions");
XposedBridge.log(grantedPerms.toString());
if (!grantedPerms.contains("android.permission.INTERNET")) {
final Object pInet = XposedHelpers.callMethod(permissions, "get", "android.permission.INTERNET");
grantedPerms.add("android.permission.INTERNET");
int[] gpGids = (int[]) XposedHelpers.getObjectField(sharedUser != null ? sharedUser : extras, "gids");
int[] bpGids = (int[]) XposedHelpers.getObjectField(pInet, "gids");
XposedBridge.log("Extended GIDs with: " + bpGids.toString());
XposedHelpers.callStaticMethod(param.thisObject.getClass(), "appendInts", gpGids, bpGids);
}
}
}
});
XposedBridge.log("Granted extra permission.");
}
The funny thing is that android.permission.INTERNET did not have to be added. It was already in the list of granted permissions.

I'm not sure what to make of this difference between AOSP and my device. The only modifications I've made are installing TWRP, SuperSU, and Xposed. To my knowledge, none modify permissions by default. But then again, I could be wrong.
I'm curious whether you have any idea about this, C3C076.
Or anyone else for that matter ...

Did you take a look at the permission list before you were testing code for adding permission or after?
Because if you previously added permission during code testing then it will be there cached in the system.

App craches on AlertDialog .show()

Hello there!
I'm building an app but whenever it comes to the AlertDialog .show() it chrashes. I've reserached but couldn't find any solution.
Most of them were got their problem fixed by changing Context on
AlertDialog.Builder example = new AlertDialog.Builder(Context)
to
AlertDialog.Builder example = new AlertDialog.Builder(MyActivity.this);
But that's not my case, I've beeing using MyActivity.this all long and still crashes.
Here's my code:
ublic class MainActivity extends AppCompatActivity {
Button btMudaTela;
final Funcoes funcao = new Funcoes();
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btMudaTela = (Button) findViewById(R.id.btMudaTela);
//Ao clicar no botão outra activity será aberta (ActivityCadastro)
btMudaTela.setOnClickListener(new View.OnClickListener() {
@override
public void onClick(View v) {
AlertDialog.Builder adb = new AlertDialog.Builder(MainActivity.this);
adb.setTitle("teste");
adb.setMessage("ok");
adb.show();
funcao.mudaActivity(MainActivity.this, ActivityCadastro.class);
finish();
}
});
}
}
And here's my Logcat:

I've found solution
Yeah!!!! After 2 days of digging on the Internet I finally found solution here:

You need to import this for your AlertDialog:
Code:
import android.app.AlertDialog;
instead of this:
Code:
import android.support.v7.app.AlertDialog;

Strange problem with supersu

The problem
situation1:
- SuperSU app is active on the foreground
- When I su from adb shell i get the confirmation prompt and get root without any problems
situation2:
- SuperSU app is not running
- When I su from adb shell
sometimes it keeps waiting indefinite but SuperSU. app never starts and therefore never asks confirmation.
other times it works like expected
situation3
- SuperSU app is not running
- Start rootexplorer it waits indefinite (super supersu app never starts)
- If i manually start SuperSU then it sometimes ask for permission for rootexplorer
Device & Rooting info
DEVICE: wiko sunny2 [v2510]
OS: Android 6.0 [MRA58K]
SuperSU version: 2.79
Rooting: Installed official SUinstaller zip version 2.79 from twrp recovery
- installation proceeded without any errors

Questions/Remarks
It looks like app_process (app_process32) is started in the wrong context
Any hints or tips on how to proceed ?

Reflashed stock and twrp and installed SuperSU the classic way (on /system)
Now everything works as expected
