Database Develop

Problem with context

Hi, I have code:
Code:
Class<?> pm =
XposedHelpers.findClass(packageManagerService, null);
hookAllConstructors(pm, packageManagerServiceHook);
packageManagerServiceHook = new XC_MethodHook() {
@Override
protected void afterHookedMethod(final MethodHookParam param) throws Throwable {
Context context = (Context) XposedHelpers.getObjectField(
param.thisObject, "mContext");
if (context == null && param.args.length != 0) {
context = (Context) param.args[0];
}
XposedBridge.log(context==null? "null" : "not null");
if (context != null) {
mContext = context;
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(ACTION_ENABLE_SIGNATURE_CHECK);
intentFilter.addAction(ACTION_DISABLE_SIGNATURE_CHECK);
mContext.registerReceiver(mBroadcastReceiver, intentFilter);
}
}
};
I get "not null" but then, I get NPE on line mContext.registerReceiver(mBroadcastReceiver, intentFilter); Any solution?

I'd check if mBroadcastReceiver is null, I don't see you assigning that. Otherwise post the full log.

[Xposed][For Devs] How to dynamically declare permissions for a target app without altering its manifest and changing its signature

Have you ever tried to extend your favorite app with new features using Xposed, but were shocked halfway that your hooked app doesn't declare a permission in AndroidManifest ? And then you spent infinite hours on the internet trying to solve this frustrating problem, you decided to use services and an external intent, but you found out that it was not convenient, and finally you gave up...
So you are like me, who wasted hours looking for a solution, until I figured out how to do it myself. Here's a snippet to save time for future Xposed enthusiasts. Put this code snippet in handleLoadPackage
Java:
// Hook will only patch System Framework
if (!lpparam.packageName.equals("android")) return;
String targetPkgName = "com.example.app"; // Replace this with the target app package name
String[] newPermissions = new String[] { // Put the new permissions here
"android.permission.INTERNET",
"android.permission.ACCESS_NETWORK_STATE"
};
String grantPermissionsMethod = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
grantPermissionsMethod = "restorePermissionState";
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.S_V2) {
XposedBridge.log("[WARNING] THIS HOOK IS NOT GUARANTEED TO WORK ON ANDROID VERSIONS NEWER THAN ANDROID 12");
}
} else if (Build.VERSION.SDK_INT == Build.VERSION_CODES.P) {
grantPermissionsMethod = "grantPermissions";
}
else {
grantPermissionsMethod = "grantPermissionsLPw";
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
XposedBridge.log("[WARNING] THIS HOOK IS NOT GUARANTEED TO WORK ON ANDROID VERSIONS PRIOR TO JELLYBEAN");
}
}
XposedBridge.hookAllMethods(XposedHelpers.findClass("com.android.server.pm.permission.PermissionManagerService", lpparam.classLoader),
grantPermissionsMethod, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
// on Android R and above, param.args[0] is an instance of android.content.pm.parsing.ParsingPackageImpl
// on Android Q and older, param.args[0] is an instance of android.content.pm.PackageParser$Package
// However, they both declare the same fields we need, so no need to check for class type
String pkgName = (String) XposedHelpers.getObjectField(param.args[0], "packageName");
XposedBridge.log("Package " + pkgName + " is requesting permissions");
if (pkgName.equals(targetPkgName)) {
List<String> permissions = (List<String>) XposedHelpers.getObjectField(param.args[0], "requestedPermissions");
for (String newPermission: newPermissions) {
if (!permissions.contains(newPermission)) {
permissions.add(newPermission);
XposedBridge.log("Added " + newPermission + " permission to " + pkgName);
}
}
}
}
});
Notes:
You must check System Framework in LSposed Manager
A reboot is required after adding the target permissions
You still need to prompt the user to accept sensitive permissions (ie android.permission.READ_CONTACTS), even if you have added them using this method

Wow, thx. Great for the install permissions!
I wrote a class to grant install and runtime/sensitive permissions (without prompting users).
Android 12 and 13 implementation:
Java:
public class Grant_Package_Permissions {
private static final int sdk = android.os.Build.VERSION.SDK_INT;
public static void hook(LoadPackageParam lpparam) {
try {
Class<?> PermissionManagerService = XposedHelpers.findClass(
sdk >= 33 /* android 13+ */ ?
"com.android.server.pm.permission.PermissionManagerServiceImpl" :
"com.android.server.pm.permission.PermissionManagerService", lpparam.classLoader);
Class<?> AndroidPackage = XposedHelpers.findClass(
"com.android.server.pm.parsing.pkg.AndroidPackage", lpparam.classLoader);
Class<?> PermissionCallback = XposedHelpers.findClass(
sdk >= 33 /* android 13+ */ ?
"com.android.server.pm.permission.PermissionManagerServiceImpl$PermissionCallback" :
"com.android.server.pm.permission.PermissionManagerService$PermissionCallback", lpparam.classLoader);
// PermissionManagerService(Impl) - restorePermissionState
XposedHelpers.findAndHookMethod(PermissionManagerService, "restorePermissionState",
AndroidPackage, boolean.class, String.class, PermissionCallback, int.class, new XC_MethodHook() {
@SuppressWarnings("unchecked")
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
// params
Object pkg = param.args[0];
int filterUserId = (int) param.args[4];
// obtém os campos
Object mState = XposedHelpers.getObjectField(param.thisObject, "mState");
Object mRegistry = XposedHelpers.getObjectField(param.thisObject, "mRegistry");
Object mPackageManagerInt = XposedHelpers.getObjectField(param.thisObject, "mPackageManagerInt");
// Continua ?
String packageName = (String) XposedHelpers.callMethod(pkg, "getPackageName");
Object ps = XposedHelpers.callMethod(mPackageManagerInt,
sdk >= 33 /* android 13+ */ ?
"getPackageStateInternal" :
"getPackageSetting", packageName);
if (ps == null)
return;
int[] getAllUserIds = (int[]) XposedHelpers.callMethod(param.thisObject, "getAllUserIds");
int userHandle_USER_ALL = XposedHelpers.getStaticIntField(Class.forName("android.os.UserHandle"), "USER_ALL");
final int[] userIds = filterUserId == userHandle_USER_ALL ? getAllUserIds : new int[]{filterUserId};
for (int userId : userIds) {
List<String> requestedPermissions;
Object userState = XposedHelpers.callMethod(mState, "getOrCreateUserState", userId);
int appId = (int) XposedHelpers.callMethod(ps, "getAppId");
Object uidState = XposedHelpers.callMethod(userState, "getOrCreateUidState", appId);
// package 1
if (packageName.equals("PACKAGE_1")) {
requestedPermissions = (List<String>) XposedHelpers.callMethod(pkg, "getRequestedPermissions");
grantInstallOrRuntimePermission(requestedPermissions, uidState, mRegistry,
Manifest.permission.RECORD_AUDIO);
grantInstallOrRuntimePermission(requestedPermissions, uidState, mRegistry,
Manifest.permission.MODIFY_AUDIO_SETTINGS);
}
// package 2
if (packageName.equals("PACKAGE_2")) {
requestedPermissions = (List<String>) XposedHelpers.callMethod(pkg, "getRequestedPermissions");
grantInstallOrRuntimePermission(requestedPermissions, uidState, mRegistry,
Manifest.permission.READ_CONTACTS);
}
}
}
});
} catch (Exception e) {
XposedBridge.log(e);
}
}
private static void grantInstallOrRuntimePermission(List<String> requestedPermissions, Object uidState,
Object registry, String permission) {
if (!requestedPermissions.contains(permission))
XposedHelpers.callMethod(uidState, "grantPermission",
XposedHelpers.callMethod(registry, "getPermission", permission));
}
}
Edit: Android 12 and 13 implementation!

this looks promising. how to use this in xposed ? is there a module available?
