如何检查应用程序是否在Android上运行？

添加下面的Helper类：

public class Helper {        public static boolean isAppRunning(final Context context, final String packageName) { final ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); final List<ActivityManager.RunningAppProcessInfo> procInfos = activityManager.getRunningAppProcesses(); if (procInfos != null) {     for (final ActivityManager.RunningAppProcessInfo processInfo : procInfos) {         if (processInfo.processName.equals(packageName)) {  return true;         }     } } return false;        }    }

现在，你可以从以下代码中检查所需的应用程序是否正在运行：

if (Helper.isAppRunning(YourActivity.this, "com.your.desired.app")) {    // App is running} else {    // App is not running}
