Creating an explicit pending intent is safer than implicit

SafePendingIntent.java

//explicit (to MyService)
Intent intent = new Intent(context, MyService.class);
PendingIntent pi = PendingIntent.getService(getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);


//implicit
Intent intent = new Intent("com.my.app.action")
PendingIntent pi = PendingIntent.getService(getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
