Question

I want my application to be automatically launched when the system is started. Can anyone tell me how to do that?

Thanks in advance for the time you will spend trying to help me.

First, you need the permission in your manifest:

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

Also, in your manifest, define your service and listen for the boot-completed action:

<service android:name=".MyService" android:label="My Service">
    <intent-filter>
        <action android:name="com.myapp.MyService" />
    </intent-filter>
</service>

<receiver
    android:name=".receiver.StartMyServiceAtBootReceiver"
    android:enabled="true"
    android:exported="true"
    android:label="StartMyServiceAtBootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

Then you need to define the receiver that will get the BOOT_COMPLETED action and start your service.

public class StartMyServiceAtBootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
            Intent serviceIntent = new Intent("com.myapp.MySystemService");
            context.startService(serviceIntent);
        }
    }
}

And now your service should be running when the phone starts up.
