Question

Is it possible to start service without starting application? I need to refresh data of my application at-least hourly, how can I do it if user no in my application?

Answer 1

you can start your service on boot.
You need the following in your AndroidManifest.xml file:

1. In your <manifest> element:

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

2. In your <application> element (be sure to use a fully-qualified [or relative] class name for your BroadcastReceiver):

In MyBroadcastReceiver.java:

package com.example;

public class MyBroadcastreceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent startServiceIntent = new Intent(context, MyService.class);
        context.startService(startServiceIntent);
    }
}
