[Q] XSharedPreferences - never loaded

Hi guys,
I'm currently a little bit confused because i try to create my first XPosed module for Xposed 2.6.1 on a Android 4.0.3 unit but i have trouble with my preferences. I tried multiple things but it was never working.
Here is the preferences code of my Settings activity. That one works and it creates a the preference file with rw-rw-r permissions and the preferences are correctly saved.
Code:
getPreferenceManager().setSharedPreferencesMode(MODE_WORLD_READABLE | MODE_MULTI_PROCESS);
getPreferenceManager().setSharedPreferencesName(Const.PACKAGE + "_preferences");
addPreferencesFromResource(R.xml.preferences);
That one is the xposed side snippet:
Code:
preferences = new XSharedPreferences(Const.PACKAGE, Const.PACKAGE+"_preferences");
if (preferences.getAll().size()==0)
{
debug("Preferences seems not to be initialized!");
}
It never loads any of my preferences. I tried the constructor XSharedPreferences(Const.PACKAGE) instead, but without any luck...
I checked the directory permissions of the settings directory, and that one seems to be correct (rwxrwxr-x).
Thanks for every help!
Bye

Have you checked what Const.PACKAGE actually is set to?

It is set to the hardcoded package Name. No class.getPackage... I added a file.isreadable and it returns false. I dont know, im just out oft any ideas.

Is there any reason why you set MODE_MULTI_PROCESS? Can you please try removing it, delete your preference file and try again?
In my UI I open SharedPreferences from <packagename>_preferences.xml
getSharedPreferences(Common.PREFERENCES_NAME, Context.MODE_WORLD_READABLE)
Click to expand...
Click to collapse
and in the module I open the settings via
new XSharedPreferences(Common.PACKAGE_NAME);
Click to expand...
Click to collapse
Please remove your current preferences file and the MODE_MULTI_PROCESS and try the code from above.

So you found any way to make it work??
I ran into the same problem, I set the preferences by the code:
SharedPreferences.Editor editor = LogExtras.getAppContext().getSharedPreferences(Commons.PACKAGE_NAME, Context.MODE_WORLD_READABLE).edit();
editor.putString("package_to_look", _packageToLook);
And when I try to get it from the module it always returns size 0
private static final XSharedPreferences preferences = new XSharedPreferences(Commons.PACKAGE_NAME, Commons.PACKAGE_NAME+"_preferences");
public static void refreshPreferences() {
Log.d("Utils", "reading prefs");
preferences.reload();
Log.d("Utils", Integer.toString(preferences.getAll().size()));
Commons.PACKAGE_TO_LOOK = preferences.getString("package_to_look", Commons.PACKAGE_TO_LOOK);
log("Package to Look: " + Commons.PACKAGE_TO_LOOK);
}

I tested the prefs in the context, and it works, only in xposed it dont load.
So I got the app saving the pref and reading the pref working, but when I try to read the pref with XSharedPreference, the size is always 0.
Already tried everything, but nothing works.

I have a similar problem, but only for one preference:
Code:
public class Main implements IXposedHookZygoteInit, IXposedHookLoadPackage {
public static final String MY_PACKAGE_NAME = Main.class.getPackage().getName();
private static XSharedPreferences pref, packagePref;
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
pref = new XSharedPreferences(MY_PACKAGE_NAME, Common.PREF);
packagePref = new XSharedPreferences(MY_PACKAGE_NAME, Common.PREF_PACKAGE);
}
@Override
public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
pref.reload();
packagePref.reload();
final String packageName = lpparam.packageName;
boolean masterSwitchOn = pref.getBoolean(Common.MASTER_SWITCH, true);
XposedBridge.log("Master Switch " + (masterSwitchOn ? "on" : "off"));
if (!masterSwitchOn) {
return;
}
if (!packagePref.getBoolean(packageName, false)) {
return;
}
Long timestamp = System.currentTimeMillis();
Long permitTimestamp = packagePref.getLong(packageName + "_tmp", 0);
if (permitTimestamp != 0 && timestamp - permitTimestamp <= 4000) {
return;
}
.
.
.
}
So, the package boolean works, the master switch doesn't…
It only seems to work after opening and closing the app multiple times.

Are you sure that your app saves the file to shared_prefs/<packagename>_preferences.xml? Better verify it using a file explorer. It's the default for preference activities, but it might not be for the methods you use.

Similar stuff here. Does your application really save the preferences in two different files, named shared_prefs/<Value of Common.PREF>.xml and shared_prefs/<Value of Common.PREF_PACKAGE>.xml? If yes, are both of these files world-readable?

You just saved my day. Making the preference files world readable solves it , preferences.makeWorldReadable() is the way to go. And yes, I'm using two preference files.
Thank you thank you thank you

[Q] hooking RecentLocationApps.getAppList()

I am trying to hook this method, I want to filter out the "Google Play services" from there...(is under settings app)
Code:
/**
* Fills a list of applications which queried location recently within
* specified time.
*/
public List<Preference> getAppList() {
// Retrieve a location usage list from AppOps
AppOpsManager aoManager =
(AppOpsManager) mActivity.getSystemService(Context.APP_OPS_SERVICE);
List<AppOpsManager.PackageOps> appOps = aoManager.getPackagesForOps(
new int[] {
AppOpsManager.OP_MONITOR_LOCATION,
AppOpsManager.OP_MONITOR_HIGH_POWER_LOCATION,
});
// Process the AppOps list and generate a preference list.
ArrayList<Preference> prefs = new ArrayList<Preference>();
long now = System.currentTimeMillis();
for (AppOpsManager.PackageOps ops : appOps) {
// Don't show the Android System in the list - it's not actionable for the user.
// Also don't show apps belonging to background users.
int uid = ops.getUid();
boolean isAndroidOs = (uid == Process.SYSTEM_UID)
&& ANDROID_SYSTEM_PACKAGE_NAME.equals(ops.getPackageName());
if (!isAndroidOs && ActivityManager.getCurrentUser() == UserHandle.getUserId(uid)) {
Preference pref = getPreferenceFromOps(now, ops);
if (pref != null) {
prefs.add(pref);
}
}
}
return prefs;
}
I can't hook this method, I'v tried something like :
Code:
if (lpparam.packageName.equals("com.android.settings")) {
findAndHookMethod("com.android.settings.location.LocationSettings", lpparam.classLoader, "getAppList", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
XposedBridge.log("Called");
}
what is the best approach to achieve this?

Why not? Are there any errors in the Xposed log?
If not, I'd make sure the package name is correct and that the method is actually called when you expect it to be.

Code:
09-29 11:06:53.600 5277 5277 I Xposed : java.lang.NoSuchMethodError: com.android.settings.location.RecentLocationApps#getAppList(java.util.List)#exact
running on Samsumg Note 3.

That error doesn't correspond to the code you've posted in the first post. Post the modified code and the error.
Purely guessing, though: Samsung modified the code you're trying to hook. You're hooking the methods you're seeing in the AOSP code, but that's not the case on your device.

You are correct, sorry. I'm trying a lot of different stuff.
this is the code:
Code:
try
{
findAndHookMethod("com.android.settings.location.RecentLocationApps", lpparam.classLoader,
"getAppList", List.class, new XC_MethodHook() {
@SuppressWarnings("unchecked")
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable
{
XposedBridge.log("RecentLocationApps.getAppList()");
}
});
}
catch(Throwable t)
{
XposedBridge.log(t);
}
the throwable is :
Code:
09-29 11:56:08.559 5282 5282 I Xposed : java.lang.NoSuchMethodError: com.android.settings.location.RecentLocationApps#getAppList(java.util.List)#exact
if tried to do that for every package, not just com.android.settings or com.android.settings.location and it doesn't seem to work.
do you know what's the correct package? do I have to start dedexing Samsung's packages to get the answer?

com.android.settings should be the correct package, if I'm not mistaken.

That'd be the best thing to do as it looks like Samsung has changed some things.

[Q] Impossible to hook a method in com.android.vending

Some week ago i posted into the request and index thread for set up a request to develop a module that will eliminate the need to have a certain amount of free space when you install app from the Play Store.
After some days i disassembled the play store apk [using APk_OneClick ] and i found the information and method i needed and wrote down into the forum, here my reply:
MonoS94 said:
Ok, i dig a bit into the play store apk for the 4.9.13 version in
Code:
com/google/android/finsky/download/
there is a class named
Code:
Storage
with two interesting method
Code:
dataPartitionAvailableSpace()
and
Code:
externalStorageAvailableSpace()
This two method return a long representing the available space into a particular partition using this formula [found in the partitionAvailable() method]
Code:
for (long l = localStatFs.getAvailableBytes(); ; l = localStatFs.getBlockSize() * localStatFs.getAvailableBlocks())
So hooking and replacing this two modules with a dummy version returning always full space we will defeat this annoying oddity, also being part of the play store apk i think that this will not affect any other app.
I hope that with this information someone will make a module.

I waited some days and about a week ago i download the ADT, set up the environment, learned a bit how to code for Android and Xposed and wrote down some code
Code:
package com.MonoS.FreeSpaceForPlayStore;
import static de.robv.android.xposed.XposedHelpers.findAndHookMethod;
import de.robv.android.xposed.IXposedHookLoadPackage;
import de.robv.android.xposed.XC_MethodReplacement;
import de.robv.android.xposed.XposedBridge;
import de.robv.android.xposed.callbacks.XC_LoadPackage.LoadPackageParam;
public class Main implements IXposedHookLoadPackage {
private static final String GOOGLE_PLAYSTORE = "com.android.vending";
public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable {
if (!lpparam.packageName.contains(GOOGLE_PLAYSTORE))
return;
XposedBridge.log("I'm in bro ;)" + lpparam.packageName);
findAndHookMethod("com.google.android.finsky.download.Storage", lpparam.classLoader, "dataPartitionAvailableSpace", XC_MethodReplacement.returnConstant(1073741824));
}
}
Compile the code, install on the phone, activate and reboot and the module don't work, it enter into the package but then throw me an ClassNotFoundError exception.
Then checked the name of all the method but they are right.
Then why can't my module hook the method??
Thanks for the attention

[Q] Does anybody uses Volley to send http request in Xposed module?

Volley is an HTTP library that makes networking for Android apps easier and faster.
We need to set the context before sending requests, according to nameless-technology.blogspot.com /2013/11/custom-system-service-using-xposedbridge.html, my testing code was:
Code:
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
...
protected void beforeHookedMethod(MethodHookParam param) throws
Throwable {
...
Context context = (Context) param.getResult();
RequestQueue queue = Volley.newRequestQueue(context);
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
msgs_g = response;
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
msgs_g = "That didn't work!";
}
});
queue.add(stringRequest);
However, when the module was loading, there's an exception:
Code:
java.lang.NullPointerException
at com.android.volley.toolbox.Volley.newRequestQueue(Volley.java:45)
at com.android.volley.toolbox.Volley.newRequestQueue(Volley.java:105)
at com.android.volley.toolbox.Volley.newRequestQueue(Volley.java:115)
at xptest.tk.xpvolley.Sendoh$1.beforeHookedMethod(Sendoh.java:61)
at de.robv.android.xposed.XposedBridge.handleHookedMethod(XposedBridge.java:611)

From code you provided it's not clear what method exactly you are hooking. But some remarks, anyway:
- are you sure original method returns context?
- I'm not sure whether using getResult() in before hook is a good practice, as you are basically asking for a return value when method was not executed, yet.
You should try after hook instead

@C3C076 Thanks for your reply.
I just modified the code from `beforeHookedMethod` to `afterHookedMethod`, at this time, I got nothing in my log.
What I want to hook is the function `dispatchSensorEvent` in the `android.hardware.SystemSensorManager$SensorEventQueue` class. Actually I don't whether this method returns context, thanks for reminding me.
Finally I used `AsyncTask` with `DefaultHttpClient` to get the data from the web site, I still use `beforeHookedMethod`.

Could you make broadcast receiver to get the color and set it
Sent from my SM-G530H using XDA Free mobile app

Problem solved. Thank you

initZygote's code runs only once, when system boots. So even if you change pref, nothing will happen.
