[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] 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

Help enabling downloads through webview (Kotlin)

Good day. I'm new to android development and I'm trying to develop a simple webview application, picked a nice template and went through the steps and made good progress, I managed to load my site fully and enable javascript, that works as intended, however I'm not able to make the app download anything, I host a few pdf files that should open or download through it, but nothing happens.
I looked at a few answers here and it is to my understanding that I need to specifically add a function for that, could you give me a hand? I have tried multiple different code and tweaking them, but I wasn't able to get it to work, here is my base code:
Code:
package com.logista.test.ui.home
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.webkit.WebResourceRequest
import android.webkit.WebView
import android.webkit.WebViewClient
import android.app.DownloadManager
import androidx.fragment.app.Fragment
import androidx.lifecycle.ViewModelProvider
import com.logista.test.R
class HomeFragment : Fragment() {
private lateinit var homeViewModel: HomeViewModel
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
homeViewModel =
ViewModelProvider(this).get(HomeViewModel::class.java)
val root = inflater.inflate(R.layout.fragment_home, container, false)
val myWebView: WebView = root.findViewById(R.id.webview)
myWebView.webViewClient = WebViewClient()
myWebView.settings.javaScriptEnabled = true
myWebView.loadUrl("https://www.example.org/")
return root
}
}
I believe I should be adding
Code:
import android.app.DownloadManager
And tweak this
Code:
// Set web view download listener
web_view.setDownloadListener(DownloadListener {
url,
userAgent,
contentDescription,
mimetype,
contentLength ->
// Initialize download request
val request = DownloadManager.Request(Uri.parse(url))
// Get the cookie
val cookies = CookieManager.getInstance().getCookie(url)
// Add the download request header
request.addRequestHeader("Cookie",cookies)
request.addRequestHeader("User-Agent",userAgent)
// Set download request description
request.setDescription("Downloading requested file....")
// Set download request mime tytpe
request.setMimeType(mimetype)
// Allow scanning
request.allowScanningByMediaScanner()
// Download request notification setting
request.setNotificationVisibility(
DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
// Guess the file name
val fileName = URLUtil.guessFileName(url, contentDescription, mimetype)
// Set a destination storage for downloaded file
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName)
// Set request title
request.setTitle(URLUtil.guessFileName(url, contentDescription, mimetype));
// DownloadManager request more settings
request.setAllowedOverMetered(true)
request.setAllowedOverRoaming(false)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
request.setRequiresCharging(false)
request.setRequiresDeviceIdle(false)
}
request.setVisibleInDownloadsUi(true)
// Get the system download service
val dManager = getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManager
// Finally, request the download to system download service
dManager.enqueue(request)
})
// Load button click listener
button_load.setOnClickListener{
// Load url in a web view
web_view.loadUrl(url)
}
}
Taken from here: https://android--code.blogspot.com/2018/03/android-kotlin-webview-file-download.html
I did the basics, renaming the function accordingly and such, but it gives me quite a few errors when building the app, for instance uri isn't defined, cookiemanager isn't defined, environment isn't defined, build isn't defined, and such, could you give me some guidance?
