简介： Failed resolution of: Landroidx/localbroadcastmanager/content/LocalBroadcastManager

集成android mqtt的时候报错：


java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/localbroadcastmanager/content/LocalBroadcastManager;


在谷歌官网找到这个类被废弃了，应该是mqtt源码实现使用了这个类，导致找不到类而报错，解决方案是：在build.gradle里添加依赖：


implementation 'com.android.support:support-v4:30.4.1'


其中30:是指你的编译版本，这个操作应该是，v4兼容包里有LocalBroadcastManager。


    implementation 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.1.0'
    implementation 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1'
    implementation 'com.android.support:support-v4:30.4.1'
