[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] when i use XPrivace.XPackageManager in my own module, error occurred, help me

[Q] when i use XPrivace.XPackageManager in my own module, error occurred, help me, urgent, thanks!
In the XPackageManager.java,
protected void after(XParam param) throws Throwable {
....
case Srv_getInstalledApplications:
if (param.getResult() != null)
if (isRestricted(param)) {
Method mGetList = param.getResult().getClass().getDeclaredMethod("ge tList");
List<ApplicationInfo> listAppInfo = (List<ApplicationInfo>) mGetList.invoke(param.getResult());
Constructor<?> constructor = param.getResult().getClass().getConstructor(List.c lass);
param.setResult(constructor.newInstance(filterAppl icationInfo(listAppInfo)));
}
break;
there throw exceptions: java.lang.NoSuchMethodException:getList[]
i log the class name use param.getResult().getClass().toString() the value is : class android.content.pm.ParceledListSlice,
but i can't import it use: import android.content.pm.ParceledListSlice;
how can i make the program run correct? thanks!

is there anybody can help me on it, thanks!

[Q] Change layout from VolumePanel

Hey there,
at the moment I'm trying to create my first Xposed Module. My wish to give the VolumePanel a new look. I found the layout and the code for the VolumePanel in AOSP here:
Code
Layout
Now I want to modify this layout but I can't get it work. I'm not sure in which package the VolumePanel is after the compilation of Android. I tried wit this code here:
Code:
resparam.res.hookLayout("android", "layout", "volume_adjust", new XC_LayoutInflated()
{
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable
{
Log.d("ME", "Layout infaleted");
LinearLayout ll = new LinearLayout(liparam.view.getContext());
ll.setOrientation(LinearLayout.VERTICAL);
ll.addView(liparam.view);
liparam.view = ll;
}
});
If I try it with this code the function is never called. As you can see here I'm trying to wrap the whole layout with a LinearLayout (for the beginning).
I'm also not realy sure if I can call the last line of code and overwrite the variable view. Is that okay or do I have to do it in another way? (but I know that the xml is in the framework-res.apk)
Would be great if you can help me with this: Can I overwrite the view in the way I do and where can I get the packageName of the volumeView?
Kind regards
Cilenco

[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.
