How to check MIUI autostart permission programmati

问题:

I need to check programmatically if the auto start permission for my app in MIUI phone is on or off. Facebook and whatsapp have this permission already enabled by default , how can I do so?

回答1:

For now it's not possible.

As it's completely depend on their operating system API's and customisation. Even developers have requested for this on XIOMI's official forums but there is no response from there side.

Till now even i am finding an answer to this question but nothing helped me.

For the time being it will be only possible for rooted phones. i.e. making customisation in their firmware by becoming super user. But this is not at all advisable as it may damage user's phones.

EDIT 1

You can redirect user to autostart permission's settings page for enabling your app using following code

String manufacturer = "xiaomi";
if (manufacturer.equalsIgnoreCase(android.os.Build.MANUFACTURER)) {
    //this will open auto start screen where user can enable permission for your app
    Intent intent1 = new Intent();
    intent1.setComponent(new ComponentName("com.miui.securitycenter", "com.miui.permcenter.autostart.AutoStartManagementActivity"));
    startActivity(intent1);
}

EDIT 2 I have recently used Mi A1 from XIOMI which have stock android (not miui) so this phone does not have autostart permission settings from miui. So take care while navigating user to the settings in such devices because it will not work here.

100% working for oppo, vivo, xiomi, letv huawei, and honor

just call this function

private void addAutoStartup() {

    try {
        Intent intent = new Intent();
        String manufacturer = android.os.Build.MANUFACTURER;
        if ("xiaomi".equalsIgnoreCase(manufacturer)) {
            intent.setComponent(new ComponentName("com.miui.securitycenter", "com.miui.permcenter.autostart.AutoStartManagementActivity"));
        } else if ("oppo".equalsIgnoreCase(manufacturer)) {
            intent.setComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.permission.startup.StartupAppListActivity"));
        } else if ("vivo".equalsIgnoreCase(manufacturer)) {
            intent.setComponent(new ComponentName("com.vivo.permissionmanager", "com.vivo.permissionmanager.activity.BgStartUpManagerActivity"));
        } else if ("Letv".equalsIgnoreCase(manufacturer)) {
            intent.setComponent(new ComponentName("com.letv.android.letvsafe", "com.letv.android.letvsafe.AutobootManageActivity"));
        } else if ("Honor".equalsIgnoreCase(manufacturer)) {
            intent.setComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.optimize.process.ProtectActivity"));
        }

        List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
        if  (list.size() > 0) {
            startActivity(intent);
        }
    } catch (Exception e) {
        Log.e("exc" , String.valueOf(e));
    }
}

This is not a perfect solution by any means and it requires some testing, but I've been able to detect the autostart permission on my Xiaomi device with it.

The autostart permission allows apps to be started by receiving an implicit broadcast intent. This method consists of scheduling an implicit broadcast with AlarmManager, killing the app and checking if the broadcast caused it to respawn. A second explicit intent is also scheduled just to make sure that the app is started eventually.

public class AutostartDetector extends BroadcastReceiver {

// I've omitted all the constant declaration to keep this snippet concise
// they should match the values used in the Manifest

public static void testAutoStart(Context context) {
    long now = System.currentTimeMillis();
    // this ID is for matching the implicit and explicit intents
    // it might be unnecessary
    String testId = Long.toHexString(now);

    Intent implicitIntent = new Intent(ACTION_IMPLICIT_BROADCAST);
    // the category is set just to make sure that no other receivers handle the broadcast
    implicitIntent.addCategory(CATEGORY_AUTOSTART);
    implicitIntent.putExtra(EXTRA_TEST_ID, testId);

    PendingIntent implicitPendingIntent =
            PendingIntent.getBroadcast(context, REQUEST_CODE_IMPLICIT_BROADCAST, implicitIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Intent explicitIntent = new Intent(ACTION_EXPLICIT_BROADCAST);
    explicitIntent.addCategory(CATEGORY_AUTOSTART);
    explicitIntent.setComponent(new ComponentName(context, AutostartDetector.class));
    explicitIntent.putExtra(EXTRA_TEST_ID, testId);

    PendingIntent explicitPendingIntent =
            PendingIntent.getBroadcast(context, REQUEST_CODE_EXPLICIT_BROADCAST, explicitIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

    // calling commit() makes sure that the data is written before we kill the app
    // again, this might be unnecessary
    getSharedPreferences(context).edit().putInt(testId, TestStatus.STARTED).commit();

    // the explicit intent is set with an additional delay to let the implicit one be received first; might require some fine tuning
    alarmManager.set(AlarmManager.RTC_WAKEUP, now + BASE_DELAY, implicitPendingIntent);
    alarmManager.set(AlarmManager.RTC_WAKEUP, now + BASE_DELAY + EXPLICIT_INTENT_DELAY, explicitPendingIntent);

    // kill the app - actually kind of tricky, see below
    SelfKiller.killSelf(context);
}

@Override
public void onReceive(Context context, Intent intent) {
    SharedPreferences sharedPreferences = getSharedPreferences(context);
    String testId = intent.getStringExtra(EXTRA_TEST_ID);

    if (testId == null) {
        Log.w(TAG, "Null test ID");
        return;
    }

    if (!sharedPreferences.contains(testId)) {
        Log.w(TAG, "Unknown test ID: " + testId);
        return;
    }

    String action = intent.getAction();
    if (ACTION_IMPLICIT_BROADCAST.equals(action)) {
        // we could assume right here that the autostart permission has been granted,
        // but we should receive the explicit intent anyway, so let's use it
        // as a test sanity check
        Log.v(TAG, "Received implicit broadcast");
        sharedPreferences.edit().putInt(testId, TestStatus.IMPLICIT_INTENT_RECEIVED).apply();
    } else if (ACTION_EXPLICIT_BROADCAST.equals(action)) {
        Log.v(TAG, "Received explicit broadcast");
        int testStatus = sharedPreferences.getInt(testId, -1);
        switch (testStatus) {
            case TestStatus.STARTED:
                // the implicit broadcast has NOT been received - autostart permission denied
                Log.d(TAG, "Autostart disabled");
                sharedPreferences.edit().putBoolean(PREF_AUTOSTART_ENABLED, false).apply();
                notifyListener(false);
                break;

            case TestStatus.IMPLICIT_INTENT_RECEIVED:
                // the implicit broadcast has been received - autostart permission granted
                Log.d(TAG, "Autostart enabled");
                sharedPreferences.edit().putBoolean(PREF_AUTOSTART_ENABLED, true).apply();
                notifyListener(true);
                break;

            default:
                Log.w(TAG, "Invalid test status: " + testId + ' ' + testStatus);
                break;
        }
    }
}

private interface TestStatus {
    int STARTED = 1;
    int IMPLICIT_INTENT_RECEIVED = 2;
}

Receiver declaration in the manifest:

<receiver android:name=".autostart.AutostartDetector">
    <intent-filter>
        <category android:name="com.example.autostart.CATEGORY_AUTOSTART"/>
        <action android:name="com.example.autostart.ACTION_IMPLICIT_BROADCAST"/>
        <action android:name="com.example.autostart.ACTION_EXPLICIT_BROADCAST"/>
    </intent-filter>
</receiver>

Killing the app reliably is another problem. I've been using this helper method:

public static void killSelf(Context context) {
    ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    activityManager.killBackgroundProcesses(context.getPackageName());

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
        // this is all we can do before ICS. luckily Xiaomi phones have newer system versions :)
        System.exit(1);
        return;
    }

    // set up a callback so System.exit() is called as soon as all
    // the activities are finished
    context.registerComponentCallbacks(new ComponentCallbacks2() {
        @Override
        public void onTrimMemory(int i) {
            if (i == TRIM_MEMORY_UI_HIDDEN) {
                Log.v(TAG, "UI Hidden");
                System.exit(1);
            }
        }

        /* ... */
    });

    // see below
    ActivityTracker.getInstance().finishAllActivities();
}

ActivityTracker is another utility that keeps track of activity lifecycles. Make sure to register it in the Application subclass.

@RequiresApi(api = Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public final class ActivityTracker implements Application.ActivityLifecycleCallbacks {
    private final ArraySet<Activity> mCreatedActivities = new ArraySet<>();

    public static ActivityTracker getInstance() {
        return Holder.INSTANCE;
    }

    public static void init(Application application) {
        application.registerActivityLifecycleCallbacks(getInstance());
    }

    public static void release(Application application) {
        ActivityTracker activityTracker = getInstance();
        application.unregisterActivityLifecycleCallbacks(activityTracker);
        activityTracker.mCreatedActivities.clear();
    }

    public void finishAllActivities() {
        // iterate over active activities and finish them all
        for (Activity activity : mCreatedActivities) {
            Log.v(TAG, "Finishing " + activity);
            activity.finish();
        }
    }

    public Set<Activity> getCreatedActivities() {
        return Collections.unmodifiableSet(mCreatedActivities);
    }

    @Override
    public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
        mCreatedActivities.add(activity);
    }    

    @Override
    public void onActivityDestroyed(Activity activity) {
        mCreatedActivities.remove(activity);
    }

    private static final class Holder {
        private static final ActivityTracker INSTANCE = new ActivityTracker();
    }

    /* ... */
}

You might also want to stop all the services just to be sure.

In addition to Nikhil's answer:

First of all, some apps like Facebook, Whatsapp are whitelisted from Xiomi by default that means auto start permission will automatically be on for these apps.

I also didn't find any way to check for auto start permission if it's enabled or not and enable it programmatically. Though as above answer suggests we can redirect user to auto start permission activity but when we have to redirect user we still don't know and also this will not work in all of the Xiomi devices.

So I used an alternative for my sync adapter to work. I stored a boolean variable named "isSyncAdapterRunning" in shared preferences and set the value of it every time sync adapter runs. This way I'll be able to know if my sync adapter is working or not.

//in my sync adapter
@Override
public void onPerformSync(Account account, Bundle extras, String authority, ContentProviderClient provider, SyncResult syncResult) {
    Log.e("TAG", "SyncStarted");
    performSync(true);        
}

public static void performSync(boolean fromSyncAdapterClass){
    //write your code for sync operation
    if(fromSyncAdapterClass){
          setValueOfIsSyncAdapterRunningVariable();
    }
}

I made other background service to perform same task if sync adapter is not working.

//In my other background service
public class BackgroundSyncService extends IntentService {

public BackgroundSyncService() {
    super("BackgroundSyncService");
}

@Override
protected void onHandleIntent(Intent intent) {
    SyncAdapter.performSync(false);        
}
}

Now start sync adapter:

// start your sync adapter here

//And after that just start that service with a condition
if(!getValueOfIsSyncAdapterRunningVariable()){
      startService(new Intent(context, BackgroundSyncService.class));
}

So basically I'm running another service to perform same task in background if my sync adapter is not working and the best thing is only one of them will run at a time. Above code will fail if user turn on auto start permission and turn off again because value of boolean variable is already set. For that you can set value of boolean variable to default once in every 24Hrs.

Hope this helps.

You have to do allow and deny for system permissions.

below is the code:

private boolean checkPermission(){
    int result = ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION);
    if (result == PackageManager.PERMISSION_GRANTED){

        return true;

    } else {

        return false;

    }
}

 @Override
 public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_REQUEST_CODE:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                Snackbar.make(view,"Permission Granted, Now you can access location data.",Snackbar.LENGTH_LONG).show();

            } else {

                Snackbar.make(view,"Permission Denied, You cannot access location data.",Snackbar.LENGTH_LONG).show();

            }
            break;
    }
}
