解决办法：

1.在Gradle：app中加入代码：

packagingOptions {
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE'
}

插入后Gradle如下：

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
buildToolsVersion '24.0.0'
useLibrary 'org.apache.http.legacy'

packagingOptions {
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE'
}

defaultConfig {
applicationId "wang.fly.com.yunhealth"
minSdkVersion 15
targetSdkVersion 25
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
repositories{
flatDir{
dirs 'libs' //存放aar的目录地址
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile name: 'SMSSDK-2.1.2', ext: 'aar'
compile name: 'SMSSDKGUI-2.1.2', ext: 'aar'
testCompile 'junit:junit:4.12'
//3.5.0：请务必查看下面注释[1]
compile 'cn.bmob.android:bmob-sdk:3.5.0'
//如果你想应用能够兼容Android6.0，请添加此依赖(org.apache.http.legacy.jar)
compile 'cn.bmob.android:http-legacy:1.0'
//配置Mob短信验证
compile 'com.android.support:appcompat-v7:25.0.0'
compile 'com.android.support:recyclerview-v7:25.0.+'
compile 'io.reactivex:rxjava:1.2.0'
compile 'io.reactivex:rxandroid:1.2.0'
compile files('libs/MobCommons-2016.1012.1447.jar')
compile files('libs/MobTools-2016.1012.1447.jar')
}

解决结果：对我无效

2.解决依赖冲突

手动导入了Bmob第三方依赖，并将冲突的依赖文件删除（据此应该可以尝试使用gradle依赖，将rxjava包的最新版导入）
