Android - Restrict to launch

I found really interesting option in Lenovo K5
When this option is active, my background services doesn't activated after restart of the device. I searched everywhere in the web, and I set some tweaks in the manifest, but nothing helps.
I notice that in some apps, that option is not activated, like Facebook or Viber. So when they can made it, I'm sure that it have some workaround of the problem.
Thanks in advance.

My Service Gets Called On Emulator But Not Real Device

When I run my app in an emulator and kill the process, my service gets started and runs in the background (Toast: "Service Called") BUT it does not get called at all on a real device and no logcat runs because the broadcast receiver or my service does not get called:
MainFest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<!-- Service -->
<service android:name=".MyService">
<intent-filter>
<action android:name="com.mypackage.myapp.MyService" />
</intent-filter>
</service>
<receiver
android:name=".BootReceiver"
android:enabled="true"
android:exported="true"
android:label="BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<!-- Service -->
MainActivity:
AsyncTask.execute(new Runnable() {
#Override
public void run() {
//TODO your background code
Intent i = new Intent(MainActivity.this, PushNotification.class);
startActivity(i);
}
});
PushNotification.class:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Context context = this;
if (!isMyServiceRunning()){
Intent serviceIntent = new Intent(context, MyService.class);
context.startService(serviceIntent);
finish();
}
else
{
finish();
}
}
private boolean isMyServiceRunning() {
ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
if (MyService.class.getName().equals(service.service.getClassName())) {
return true;
}
}
return false;
}
BootReceiver:
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent serviceIntent = new Intent(context, MyService.class);
context.startService(serviceIntent);
}
}
}
MyService:
public class MyService extends Service {
Handler handler;
#Override
public int onStartCommand(Intent intent, int flags, int startId){
// START YOUR TASKS
Toast.makeText(MyService.this, "Service Called", Toast.LENGTH_SHORT).show();
Context context = this;
Intent in = new Intent(context, FragmentMain.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
in.putExtra("valuerunInBG", "1");
context.startActivity(in);;
//loop();
return super.onStartCommand(intent, flags, startId);
}
#Override
public void onDestroy() {
// STOP YOUR TASKS
super.onDestroy();
}
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}

Modify your manifest as given below
<receiver
android:name=".BootReceiver"
android:enabled="true"
android:exported="true"
android:label="BootReceiver">
<intent-filter android:priority="1000">
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
I made a small change in it just given the priority by which it will start as early as possible
also change the code given below
#Override
public int onStartCommand(Intent intent, int flags, int startId){
// START YOUR TASKS
Toast.makeText(MyService.this, "Service Called", Toast.LENGTH_SHORT).show();
Context context = this;
Intent in = new Intent(context, FragmentMain.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
in.putExtra("valuerunInBG", "1");
context.startActivity(in);;
//loop();
return START_STICKY; //THIS WILL RESTART YOUR SERVICE IF IT GETS STOPPED BY ANDROID OS DUE TO LOW MEMORY
}

android.intent.action.BOOT_COMPLETED Takes time after your device starts, try waiting 3-4 minutes

Start your service again in your service class's onDestroy() method. This way when your application will be closed, then onDestroy() will be called and that will start your service again.

Some time Toast does not work inside of Service so please use Log to know whether your code is running or not.

Run service after device was restarted

I want that one of my services runs even if user has restarted device. I've tried this code but didn't succeed. What should I do? Help me please.
Thank you!
MyService2.class:
public class MyService2 extends Service {
private MyReceiver mR = null;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mR = new MyReceiver();
IntentFilter intentFilter = new IntentFilter(Intent.ACTION_BOOT_COMPLETED);
registerReceiver(mR, intentFilter);
}
}
MyReceiver.class
public class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
context.startService(new Intent(context, MyService.class));
context.startService(new Intent(context,MyService2.class));
}
}
}

You are Registering your BroadcastReciver in your Service , Which your trying to start using your BroadcastReciver which is not registered.
So try registering your broadcast Reciever in your manifest file like this
<receiver android:name="your broadcast class">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter

First no need to register your receiver in service. Add your broadcast receiver in Manifest.
Like :
<receiver android:name="your broadcast class">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
Remember to add permission also :
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
When device is rebooted your receiver will automatically get executed by system as it is declared in manifest. In your receiver just start your service.
public class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
//add a log or toast to confirm the receive
context.startService(new Intent(context, MyService2.class));
}
}
}
AND
public class MyService2 extends Service {
private MyReceiver mR = null;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// do what ever you wanted to do...
}
}

Service and bootup code not working

I am trying to create a service that will run on bootup, however when trying it in my emulator the log is not showing my message through log tag, so clearly something is wrong.
Here is my code.
service.java
public class service extends Service {
private static final String TAG = "myapp.mycomp";
public service() {
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i(TAG, "Service started");
Runnable r = new Runnable() {
#Override
public void run() {
/** something to do **/
}
};
Thread service = new Thread(r);
service.start();
return Service.START_STICKY;
}
#Override
public void onDestroy() {
Log.i(TAG, "Service stopped");
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
MyReceiver.java
public class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent myIntent = new Intent(context, service.class);
context.startService(myIntent);
}
}
XML manifest intent
<receiver android:name=".MyReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
XML manifest permission
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Service not getting called on Phone startup - Android

I have tried this
Trying to start a service on boot on Android
Also I have checked with http://blog.vogella.com/2011/12/11/automatically-starting-services-in-android-after-booting/
yet my app wont restart on Phone startup. Here's the code.
AndroidManifest.xml
<service android:name=".MyService">
</service>
<receiver android:name=".Autostart"
android:enabled="true"
android:exported="false">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
MyService
public class MyService extends Service implements LocationListener {
#Override
public IBinder onBind(Intent intent) {
return mBinder;
}
private final IBinder mBinder = new LocalBinder();
public class LocalBinder extends Binder {
MyService getService() {
return MyService.this;
}
}
#Override
public void onCreate() {
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i("LocalService", "Received start id " + startId + ": " + intent);
// We want this service to continue running until it is explicitly
// stopped, so return sticky.
return START_STICKY;
}
#Override
public void onDestroy() {
// Cancel the persistent notification.
this.stopSelf();
// Tell the user we stopped.
}
MainActivity
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
startService(new Intent(getBaseContext(), MyService.class));
Am I going wrong anywhere?
Edit:
public void onReceive(Context arg0, Intent arg1)
{
Intent intent = new Intent(arg0,MyService.class);
arg0.startService(intent);
Log.i("Autostart", "started");
}
This is my BroadcastReceiver.
Yet no results.

try register BroadcastReceiver for ACTION_BOOT_COMPLETED. The you can recieve startup broadcast.
public class BootBroadCast extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
Intent service=new Intent(context, MyService.class);
context.startService(service);
}
}
second you need add this in AndroidManifest.xml
<receiver android:name=".BootBroadCast" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" >
</action>
</intent-filter>
</receiver>

I have followed the article at vogella and was able to get my service started at Boot.
First of all, you should have a BroadcastReceiver for the event android.intent.action.BOOT_COMPLETED. Just follow the steps from the blog. It seems you have started the service on your app's 'onCreate'. This will get invoked only if the user starts your app.
When the system boots up, your receiver class's onReceive() method will be invoked. Here is where you should start your activity as below.
public class BootReceiever extebds BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, YourService.class);
context.startService(service);
}
}
From the research that I have done, it is better to start your service after a short delay as many applications / services may start at boot, so chances of low memory are more. I started my service after a small delay.
