Java 如何修复Android Studio中停止的应用程序？

当我调试应用程序成功构建，但在我的监控设备上出现“应用程序已停止”通知时，会导致致命的崩溃。在我的logcat中，我发现了两个错误，以…引起的行开头。现在，我的问题是，我不知道如何处理这些错误，所以我修复了我的应用程序。我对Android编程还很陌生

以下是我怀疑错误产生的两种方法：

@Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        if (intent.getStringExtra("url") != null)
            playStream(intent.getStringExtra("url"));

        if (intent.getAction().equals(Constants.ACTION.STARTFOREGROUND_ACTION)) {
            Log.i("info", "Start foreground service!");
            showNotification();

        } else if (intent.getAction().equals(Constants.ACTION.PREV_ACTION)) {
            Log.i("info", "Prev pressed.");

        } else if (intent.getAction().equals(Constants.ACTION.PLAY_ACTION)) {
            Log.i("info", "Play pressed.");

        } else if (intent.getAction().equals(Constants.ACTION.NEXT_ACTION)) {
            Log.i("info", "Next pressed.");

        } else if (intent.getAction().equals(Constants.ACTION.STOPFOREGROUND_ACTION)) {
            Log.i("info", "Stop foreground received.");
            stopForeground(true);
            stopSelf();
        }

        return START_REDELIVER_INTENT;
    }

以及：

注意：我注意到在Android Studio中，新的任务“Notification.Builder”被一行类似取消的语句打断；我不知道那是什么意思

您有这个错误

原因：java.lang.SecurityException:权限拒绝： 从pid=27871、uid=10172开始的起始地面 android.permission.FOREGROUND\u服务

这意味着您需要在Android清单中添加权限

<manifest ...>
     ...
     <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
     ...
     <application ...>
     ...
