从另一个应用程序获取android设备中的正在运行的应用程序

Question

我正在使用此代码来在Android应用程序的Forground中运行应用程序。

ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> runningAppProcessInfo = am.getRunningAppProcesses();

for (int i = 0; i < runningAppProcessInfo.size(); i++) {

    if(runningAppProcessInfo.get(i).processName.equals("com.the.app.you.are.looking.for")) {
        // Do your stuff here.
      }
    }

public static boolean isForeground(Context ctx, String myPackage){
    ActivityManager manager = (ActivityManager) ctx.getSystemService(ACTIVITY_SERVICE);
    List< ActivityManager.RunningTaskInfo > runningTaskInfo = manager.getRunningTasks(1); 

    ComponentName componentInfo = runningTaskInfo.get(0).topActivity;
    if(componentInfo.getPackageName().equals(myPackage)) {
        return true;
    }       
    return false;
}

但无法使用此代码获取正在运行的应用程序信息。

任何帮助将不胜感激。

这可能对您有帮助

final ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
final List<RunningTaskInfo> recentTasks = activityManager.getRunningTasks(Integer.MAX_VALUE);

for (int i = 0; i < recentTasks.size(); i++) 
{
    Log.d("Testing", "Application executed : " +recentTasks.get(i).baseActivity.toShortString()+ "\t\t ID: "+recentTasks.get(i).id+"");         
}
