Android，构建成功，但 apk 构建（后续运行）失败

Question

我最近升级到了 Android Studio 1.2 测试版。 早先编译良好的项目失败了。 我必须在 gradle 文件中进行一些修改才能再次编译项目。 现在构建成功了，但是，当我尝试构建 apk 时，构建失败了。

这里是项目详情。

Gradle 文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion '22.0.1'
    defaultConfig {
        applicationId "mcc.abcd"
        minSdkVersion 16
        targetSdkVersion 22
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:22.0.0'
    compile 'com.google.android.gms:play-services:7.0.0'
    //compile files('libs/google-play-services.jar')
    compile project(':app:libraries:PebbleKitAndroid:app')
    compile project(':app:libraries:Weka-for-Android-master:app')
}

构建错误

我已经尝试过更改 buildToolsVersion、sdk 版本等，但还没有成功。 请帮忙。

Answer 1

失败的原因在构建输出的第二行 - "com.android.dex.DexIndexOverflowException: Cannot merge new index 68094 into a non-jumbo instruction!"

这意味着您的应用程序已达到最大方法限制，com.google.android.gms:play-services 是巨大的（就像在很多方法中一样）

最简单的解决方案是使用您实际需要的 Play 服务组件作为described in official docs，例如

compile 'com.google.android.gms:play-services-gcm:7.0.0'

代替你的

compile 'com.google.android.gms:play-services:7.0.0'

Answer 2

听起来你已经达到了 dex 限制。 dex 格式的限制意味着您的项目中只能有 65536 个方法。

谢天谢地，自 Android API 版本 21 以来，现在就存在多 dex 支持。

您可以这样启用它：

android {
   defaultConfig {
      ...
      multiDexEnabled = true
      ...
   }
}

还值得注意的是，您可能不需要包含所有 Google Play 服务和you can pick and choose the required modules your app needs。
