Android13集成paho.mqtt.android启动异常

项目中原依赖是：

复制代码

implementation('org.eclipse.paho:org.eclipse.paho.android.service:1.1.1') {
    exclude module: 'support-v4'
    transitive = true
}
implementation 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.2.5'

在Android10系统运行正常，能够连接服务端，在Android13中出错，log如下：

E/AndroidRuntime: FATAL EXCEPTION: MQTT Rec: paho4782357715513

Process: com.xxx.xxxx, PID: 24859

java.lang.IllegalArgumentException: com.xxx.xxxx: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.

Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

查询系统中使用：PendingIntent的地方做了版本判断，

复制代码

PendingIntent piResult;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.S) {
    piResult = PendingIntent.getActivity(context, 0, resultIntent, PendingIntent.FLAG_IMMUTABLE);
} else {
    piResult = PendingIntent.getActivity(context, 0, resultIntent, PendingIntent.FLAG_ONE_SHOT);
}

替换后依然启动报错，错误如上面相同，然后查询方法（mqtt库无法兼容高版本android13的问题），给与帮助，使用

paho.mqtt.android 3.3.0 的版本可以正常运行，
下载 serviceLibrary-release.aar导入项目libs中，dependencies中添加依赖

implementation files('libs/serviceLibrary-release.aar')

移除依赖： implementation('org.eclipse.paho:org.eclipse.paho.android.service:1.1.1')

原先所有导入import org.eclipse.paho.android.service.MqttAndroidClient 替换成：import info.mqtt.android.service.MqttAndroidClient ；

在MQTT android客户端，添加最后一个Ack.AUTO_ACK参数

client = new MqttAndroidClient(context, serverURI, clientId, Ack.AUTO_ACK);

替换后运行出现的错误是：

E/AndroidRuntime: FATAL EXCEPTION: MQTT Rec: paho5848521383808

java.lang.NoClassDefFoundError: Failed resolution of: Ltimber/log/Timber;

然后添加timber导入：

复制代码

implementation 'com.jakewharton.timber:timber:4.7.1'

编译后重新运行正常了
