按照官方文档：
代码语言：txt复制dependencies {
implementation 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.0.2'
implementation 'org.eclipse.paho:org.eclipse.paho.android.service:1.0.2'
}编译时发生冲突：
代码语言：txt复制Duplicate class androidx.viewpager.widget.ViewPager$SimpleOnPageChangeListener found in modules jetified-support-v4-r7 (com.google.android:support-v4:r7) and viewpager-1.0.0-runtime (androidx.viewpager:viewpager:1.0.0)原因是官方文档没有及时更新，这个bug已经在新版本被修正：
代码语言：txt复制dependencies {
implementation 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.2.4'
implementation 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1'
}
