How to find out if a Skype call is currently active on Android

Question

Okay, I decompiled Skype's manifest to find out if there are any Services or Broadcasts running during a call. There are only a few internal broadcasts for incoming calls. Also only one receiver and one service exist.

I monitored all running services with my app, but the SkypeMainService is always running, even if not in a call.

Also AudioMode is not changed by skype (but according to the logcat-logs the dev wanted to, but they just don't do it), so I cannot simply check if it is MODE_IN_CALL.

Do you have any suggestions how to find out, if Skype is currently running and having an active call?

Thanks!

/edit: A brief overview of the Activities etc:

<activity android:name="com.skype.raider.Main">
<activity-alias android:name="com.skype.raider.ui.SplashScreenActivity" android:targetActivity="com.skype.raider.Main">
<receiver android:name="com.skype.MainReceiver" android:enabled="true" android:exported="false">
   <action android:name="android.intent.action.BOOT_COMPLETED" />
   <action android:name="android.intent.action.MEDIA_MOUNTED" />
   <action android:name="android.intent.action.SEARCH" />
   <action android:name="android.intent.action.CALL_PRIVILEGED" />
   <action android:name="com.skype.raider.INCOMING_GSM_CALL" />
   <action android:name="com.skype.raider.ON_GSM_CALL" />
   <action android:name="com.skype.raider.intent.action.request_sync" />
</receiver>
<service android:name="com.skype.MainService">

Answer 1

Okay, I really hoped someone would provide a useful answer. However, I picked up Reuben's advice in the comment and made this method:

/**
 * Gets the current activity
 * 
 * @param context
 *            A context to use
 * @return The Activity name
 */
public static String getCurrentTopActivity(Context context) {
    ActivityManager mActivityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    List<ActivityManager.RunningTaskInfo> RunningTask = mActivityManager.getRunningTasks(1);
    ActivityManager.RunningTaskInfo ar = RunningTask.get(0);
    return ar.topActivity.getClassName().toString();
}

Then I check if the result equals com.skype.raider.Main. This will also return true if there is no active Skype call, but the main app is open.

Thanks for all the help, especially Reuben!

Edit: Your will need the following permission in your manifest

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