Crash - Securityexception: Permission Denial: Isuidactive From Pid=xxxx, Uid=xxxx Requires Android.permission.package_usage_stats

I'm getting an unknown crash from Crashlytics which triggered on calling enableReaderMode() in NfcAdapter Caused by java.lang.SecurityException: Permission Denial: isUidActive from

Solution 1:

I don't know why it's requesting that but there is such permission:

<uses-permissionandroid:name="android.permission.PACKAGE_USAGE_STATS"tools:ignore="ProtectedPermissions" />

You can check if your app has it by calling:

publicstaticbooleancheckForUsagePermission(Context context) {
        @SuppressLint("WrongConstant")UsageStatsManagerusm= (UsageStatsManager) context.getSystemService("usagestats");
        longtime= System.currentTimeMillis();
        return usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, time - 1000 * 1000, time).size() > 0;
    }

And, of course, you can request it by:

IntentsettingsIntent=newIntent(Settings.ACTION_USAGE_ACCESS_SETTINGS);
            startActivityForResult(settingsIntent, REQUEST_STATS_USAGE);

Solution 2:

Found that, special permissions that are granted by the user in the system settings (usage stats access, notification access, …) are handled by AppOpsManager, which was added in Android 4.4. Therefore, I'm adding an extra check as follows

val mode = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        (getSystemService(Context.APP_OPS_SERVICE) as AppOpsManager).unsafeCheckOpNoThrow(
            AppOpsManager.OPSTR_GET_USAGE_STATS,
            Process.myUid(),
            packageName
        )
    } elsenullval granted = if (mode != null && mode != AppOpsManager.MODE_DEFAULT) {
       mode == AppOpsManager.MODE_ALLOWED
    } else {
       checkCallingOrSelfPermission(Manifest.permission.PACKAGE_USAGE_STATS) == PackageManager.PERMISSION_GRANTED
    }
