Android how to find out which app opens in any instance
In my application, I want to show a message using a BroadcastReceiver, but I want it to display a toast message only when the application is not open and is currently running on the screen (it can run in the background). But I don't find the exact code to fulfill the condition accordingly.
I have tried the code,
ActivityManager manager =
(ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
List<RunningAppProcessInfo> processes = manager.getRunningAppProcesses();
but it also stops the message when another app starts.
Please help me, how can I tell my code if the application is currently open or not? Thank.

With that answer in mind , and finally cyanogenmod 7.
You're halfway there. RunningAppProcessInfo has a pkgList field, String [], which contains all the package names in the process that you can match against to determine if this is your application.
private RunningAppProcessInfo getForegroundApp() {
RunningAppProcessInfo result=null, info=null;
if(mActivityManager==null)
mActivityManager = (ActivityManager)mContext.getSystemService(Context.ACTIVITY_SERVICE);
List <RunningAppProcessInfo> l = mActivityManager.getRunningAppProcesses();
Iterator <RunningAppProcessInfo> i = l.iterator();
while(i.hasNext()){
info = i.next();
if(info.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND
&& !isRunningService(info.processName)){
result=info;
break;
}
}
return result;
}
