title: How to specify supported architectures for android app in build.gradle?
body: <p>My Android app supports only arm64-v8a and armeabi-v7a. However, due to one of the dependencies, I see the following in my lib folder of the apk:</p>
  
  <pre><code>arm64-v8a
  armeabi
  armeabi-v7a
  mips
  x86
  x86_64
  </code></pre>
  
  <p>Here is my 
  <strong>build.gradle:</strong></p>
  
  <pre><code>buildscript {
      repositories {
          maven { url 'https://maven.fabric.io/public' }
      }
  
      dependencies {
          classpath 'io.fabric.tools:gradle:1.+'
      }
  }
  apply plugin: 'com.android.application'
  apply plugin: 'io.fabric'
  
  repositories {
      maven { url 'https://maven.fabric.io/public' }
  }
  
  
  android {
      compileSdkVersion Integer.parseInt(project.ANDROID_BUILD_SDK_VERSION)
      buildToolsVersion project.ANDROID_BUILD_TOOLS_VERSION

          applicationId "com.mycompany.myapp"
          minSdkVersion Integer.parseInt(project.ANDROID_BUILD_MIN_SDK_VERSION)
          targetSdkVersion Integer.parseInt(project.ANDROID_BUILD_TARGET_SDK_VERSION)
          versionCode Integer.parseInt(project.VERSION_CODE)
          versionName project.VERSION_NAME
          multiDexEnabled true
      }
  
      dexOptions {
          javaMaxHeapSize "4g"
      }
  
      buildTypes {
          release {

              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
  }
  
  dependencies {
      compile fileTree(include: ['*.jar'], dir: 'libs')
      testCompile 'junit:junit:4.12'
      compile 'com.android.support:appcompat-v7:24.0.0'
      compile 'com.android.support:design:24.0.0'
      compile 'com.android.support:support-v4:24.0.0'
