判斷的當前的app是否還存活

判斷程序是否還在手機中存活

返回的是boolean值

	public boolean isAppaLive(Context context ,String str) {
		ActivityManager am = (ActivityManager) context
				.getSystemService(Context.ACTIVITY_SERVICE);
		List<RunningTaskInfo> list = am.getRunningTasks(100);
		boolean isAppRunning = false;
		//String MY_PKG_NAME = "你的包名";
		for (RunningTaskInfo info : list) {
			if (info.topActivity.getPackageName().equals(str)//如果想要手動輸入的話可以str換成<span style="font-family: Arial, Helvetica, sans-serif;">MY_PKG_NAME，下面相同</span>
					|| info.baseActivity.getPackageName().equals(str)) {
				isAppRunning = true;
				Log.i(TAG, info.topActivity.getPackageName()
						+ " info.baseActivity.getPackageName()="
						+ info.baseActivity.getPackageName());
				break;
			}
		}
		return isAppRunning;
	}
