Answer 1

if your BroadcastReceiver is defined in a separate class file, then you may simply broadcast the value to that receiver. Once the value is received, do the magic for service by using receiver's context

Update:

in your activity:

Intent in = new Intent("my.action.string");
in.putExtra("state", "activated");
sendBroadcast(in);

in your receiver:

@Override
public void onReceive(Context context, Intent intent) {
  String action = intent.getAction();

  Log.i("Receiver", "Broadcast received: " + action);

  if(action.equals("my.action.string")){
     String state = intent.getExtras().getString("state");
     //do your stuff
  }
}

in manifest xml:

<receiver android:name=".YourBroadcastReceiver" android:enabled="true">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        <action android:name="my.action.string" />
        <!-- and some more actions if you want -->
    </intent-filter>
</receiver>

Intent i= new Intent(this, YourReceiver.class);
i.putExtra("txt", "the string value");
startActivity(i)

And then in your receiver, start the service using the startService function
