Android - Start Service on Boot

Android - Start service on boot

Well here is a complete example of an AutoStart Application

AndroidManifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="pack.saltriver" android:versionCode="1" android:versionName="1.0">

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

    <application android:icon="@drawable/icon" android:label="@string/app_name">

        <receiver android:name=".autostart">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>

        <activity android:name=".hello"></activity>
        <service android:enabled="true" android:name=".service" />
    </application>
</manifest>

autostart.java

public class autostart extends BroadcastReceiver 
{
    public void onReceive(Context context, Intent arg1) 
    {
        Intent intent = new Intent(context,service.class);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            context.startForegroundService(intent);
        } else {
            context.startService(intent);
        }
        Log.i("Autostart", "started");
    }
}

service.java

public class service extends Service
{
    private static final String TAG = "MyService";
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
    public void onDestroy() {
        Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
        Log.d(TAG, "onDestroy");
    }

    @Override
    public void onStart(Intent intent, int startid)
    {
        Intent intents = new Intent(getBaseContext(),hello.class);
        intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intents);
        Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
        Log.d(TAG, "onStart");
    }
}

hello.java - This will pop-up everytime you start the device after executing the Applicaton once.

public class hello extends Activity 
{   
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Toast.makeText(getBaseContext(), "Hello........", Toast.LENGTH_LONG).show();
    }
}

How to start a service automatically using broadcastreceivers after booting?

Follow this step one by one.

Create this Receiver class:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;


public class BootUpReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        /****** For Start Activity *****/
        Intent i = new Intent(context, MyActivity.class);  
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);  

        /***** For start Service  ****/
        Intent myIntent = new Intent(context, ServiceClassName.class);
        context.startService(myIntent);
    }   

}

In AndroidManifest.xml:

<receiver 
    android:enabled="true" 
    android:name=".BootUpReceiver"
    android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>
<service
    android:name=".ServiceClassName"
    android:enabled="true"
    android:exported="true" >
</service>

Starting background service when Android turns on

use <action android:name="android.intent.action.BOOT_COMPLETED" /> for starting your service when the device turns on.

In AndroidManifest.xml:

 <receiver android:name=".BootBroadcastReceiver" >   
            <intent-filter>   
                <action android:name="android.intent.action.BOOT_COMPLETED" />   
            </intent-filter>   
        </receiver> 

Add permission in your AndroidManifest.xml as:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED">
</uses-permission>

In code part BootBroadcastReceiver:

public class BootBroadcastReceiver extends BroadcastReceiver {     
    static final String ACTION = "android.intent.action.BOOT_COMPLETED";   
    @Override   
    public void onReceive(Context context, Intent intent) {   
        // BOOT_COMPLETED” start Service    
        if (intent.getAction().equals(ACTION)) {   
            //Service    
            Intent serviceIntent = new Intent(context, StartOnBootService.class);       
            context.startService(serviceIntent);   
        }   
    }    
}   

EDIT: if you are talking about device screen on/off then you need to register <action android:name="android.intent.action.USER_PRESENT" /> and <action android:name="android.intent.action.SCREEN_ON" /> for starting your service when user is present or screen is on.

Start Service at boot without activity

From Android 3.1, BroadcastReceiver will not work until the user has manually launched an activity, This is for provide security . once the user runs the app for the first time then your BroadcastReceiver will run always except it does not Force Stop it. Once activity launch at first time your broadcast receiver will run even after reboot your deice.

Therefore in your application you must have one Activity to run BroadcastReceiver.

How can I start android application on device boot?

After I added the boot permissions in manifest file (see code below), BroadcastReceiver started to get boot completed event and the service is starting successfully. For the solution to work (as suggested by @Eren Tüfekçi) I had to enable auto start permission in phone settings for my application. If anyone has a solution, how to enable it programmatically, please let us know. Thank you.

        <service android:enabled="true"
            android:name="kor.location.tracker.WorkerService"
            android:exported="true"
            android:permission="android.permission.BIND_JOB_SERVICE"
            />

    </application>

</manifest>

Start Service on boot but not entire Android app

First you have to create a receiver:

public class BootCompletedReceiver extends BroadcastReceiver {

    final static String TAG = "BootCompletedReceiver";

    @Override
    public void onReceive(Context context, Intent arg1) {
        Log.w(TAG, "starting service...");
        context.startService(new Intent(context, YourService.class));
    }
}

Then add permission to your AndroidManifest.xml:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

and register intent receiver:

<receiver android:name=".BootCompletedReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

After this is done, your application (Application class) will run along with services, but no Activities.

Ah, and don't put your application on SD card (APP2SD or something like that), because it has to reside in the main memory to be available right after the boot is completed.
