  1. POScreen receiver not working within my Service
    text
    copied!<p>I am trying to get my Screen ON/OFF to work on my Service, but so far no luck.</p> <p>The goal is: Get the LED lights ( softkeys ) to go out when the screen goes OFF and Softkey light to turn ON when the screen goes back ON with the values the user inputed on my app ( you will see the TextXLActivity.getledC() which gets the Int from the main activity ) </p> <p>On my main activity i can control the LED lights without any problem, with a SeekBar and so on. Only thing not working is really the Receiver/Service</p> <p>Now when I go to settings, applications, running services, my App is not listed anywhere, I am affraid my Service isn't starting at all, and maybe that is the problem here. </p> <p>Here is my Receiver:</p> <pre><code>package com.test.xl; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; public class ScreenReceiver extends BroadcastReceiver { private boolean screenOff; @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) { screenOff = true; } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) { screenOff = false; } Intent i = new Intent(context, UpdateService.class); i.putExtra("screen_state", screenOff); context.startService(i); } } </code></pre> <p>And here my Service:</p> <pre><code>package com.test.xl; import com.sonyericsson.illumination.IlluminationIntent; import android.app.Service; import android.content.BroadcastReceiver; import android.content.Intent; import android.content.IntentFilter; import android.os.IBinder; public class UpdateService extends Service { @Override public void onCreate() { super.onCreate(); // register receiver that handles screen on and screen off logic IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON); filter.addAction(Intent.ACTION_SCREEN_OFF); BroadcastReceiver mReceiver = new ScreenReceiver(); registerReceiver(mReceiver, filter); } @Override public void onStart(Intent intent, int startId) { boolean screenOn = intent.getBooleanExtra("screen_state", false); if (!screenOn) { { Intent led = new Intent(IlluminationIntent.ACTION_START_LED); led.putExtra(IlluminationIntent.EXTRA_PACKAGE_NAME, "com.test.xl"); led.putExtra(IlluminationIntent.EXTRA_LED_ID, IlluminationIntent.VALUE_BUTTON_2); led.putExtra(IlluminationIntent.EXTRA_LED_COLOR, TestXLActivity.getledC()); startService(led); } } else { Intent led = new Intent(IlluminationIntent.ACTION_STOP_LED); led.putExtra(IlluminationIntent.EXTRA_PACKAGE_NAME, "com.test.xl"); led.putExtra(IlluminationIntent.EXTRA_LED_ID, IlluminationIntent.VALUE_BUTTON_2); led.putExtra(IlluminationIntent.EXTRA_LED_COLOR, 0xFFFFFFFF); startService(led); } } @Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub return null; } } </code></pre> <p>This is a Test app I started to try and understand the Receiver/Service "relation", any help would be appreciated! ;)</p> <p>I also noticed that my Service forces me to implement this lines:</p> <pre><code>@Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub return null; } </code></pre> <p>I followed a tutorial on how to get my service to interact with the Receiver and the source code there had nothing like that at the end, any guesses?
