AutoStart App on Device BootUP

[Fred Grott]

Well, I guess I beter ask a question..

I am developing a system o bring non web widgets to android using two components, A Modified HomeScreenApp and the Widget itself.
Is there a specific Android Manifest attribute that allows an app to AutoStart on device bootup?

i think you can use BroadcastReceiver

I was under the impression that BroadCast receiver is once the app has started

Yes, you need to request for permission android.permission.RECEIVE_BOOT_COMPLETED , you have to declare it outside the <application> node of Android Manifest file as,

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

When the phone boots, an Intent is broadcasted to all apps who have registered to receive this Intent. To register for this Intent, like Imran said, you have to use BroadcastReceiver, first declare a receiver inside the <application> node as,

<receiver android:enabled="true"
                   	android:name=".MyReceiver"
                        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>

MyReceiver.java is the class that will receive the Intent. You will handle the Intent in the onReceive() method of BroadcastReceiver class. You get approx. 5 secs to do what you want inside onReceive(), after that the system will show 'App not responding' dialog to the user, so make sure you don't do any heavy processing inside that method.

and than you have to start your Activity form the onReceive() method of BroadcastReceiver class
i.e

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

public class My_BroadcastReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		Intent i = new Intent(context, YourActivity.class);
		context.startActivity(i);
	}
}   

i don't know how much it is reliable..... but generally i use this...!!!
