Android OS 14 的 MQTT 错误：库中的“java.lang.SecurityException”

Question

我的 Android 应用程序遇到问题，特别是在运行 Android OS 14 的设备上。该应用程序因与库文件相关的“java.lang.SecurityException”而崩溃。我正在使用以下库：

androidx.localbroadcastmanager:localbroadcastmanager:1.1.0
org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.2.5
org.eclipse.paho:org.eclipse.paho.android.service:1.1.1

这是我的 AndroidManifest.xml 的片段：

<service
    android:exported="false"
    android:name="org.eclipse.paho.android.service.MqttService" />

我不确定如何解决这个问题，特别是因为它发生在库文件中。任何帮助将不胜感激。

经过长时间的研发终于找到了解决方案

在每个registerReceiver中添加RECEIVER_EXPORTED以供参考。

在AlarmPingSender.java文件中

找到 registerReceiver 并使用下面的内容更新该行

 service.registerReceiver(alarmReceiver, new IntentFilter(action), RECEIVER_EXPORTED);

在MqttService.java文件中

找到 registerBroadcastReceivers() 并更新这一行

registerReceiver(networkConnectionMonitor, new IntentFilter(
                ConnectivityManager.CONNECTIVITY_ACTION),RECEIVER_EXPORTED);

在 Adnroid Manifest 中添加此权限

 <uses-permission android:name="android.permission.USE_EXACT_ALARM" />
