2021-11-06 android build时报错META-INF/rxjava.properties

解决办法：

在app/build.gradle中添加：

        packagingOptions{ 
          exclude 'META-INF/rxjava.properties' 
        }

即可解决。 添加后 得到：

android {
    compileSdkVersion 30
    buildToolsVersion '31.0.0'
    flavorDimensions "default"
    defaultConfig {
        applicationId "com.xxx.xx"
        minSdkVersion 17
        targetSdkVersion 30
        testInstrumentationRunner 'androidx.test.runner.AndroidJUnitRunner'
        multiDexEnabled true
        versionName "2.4.8"
        packagingOptions{ 
          exclude 'META-INF/rxjava.properties' 
        }
    }
