Answer 1

Per the following post:

How to start an Application on startup?

You might need a Receive_boot_completed permission. There are two answers in the post which show how to start either an activity or a service on app start.

Answer 2

When you switch on the mobile, an intent will be broadcasted. Its android.intent.action.BOOT_COMPLETED.

If you receive that intent via a broadcasted receiver then it you can detect if the device is switched on.

Broadcast Receiver:

    public class BootReceiver extends BroadcastReceiver { 

    @Override
    public void onReceive(Context aContext, Intent aIntent) { 

            // ToDo: Whatever I need at immediately after bootstrap
            Toast.makeText(aContext, "This message phone is turned on!", Toast.LENGTH_LONG).show();
            Log.e("..BOOT_ACTION_NAME...", "This message phone is turned on!");


}}

Manifest Declaration:

<receiver
        android:name="com.example.testing_demo.BootReceiver"
        android:enabled="true" 
        android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
        <intent-filter>
            <action android:name="android.intent.action.SCREEN_ON" />
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>

Place the manifest code inside the application tag.
