Question

我最近升级到Android studio 1.2 beta。早先编好的项目破产了。我不得不在gradle文件中进行一些修改，以便再次编译项目。现在构建成功，但是，当我尝试构建apk时，构建失败。

以下是项目详情。

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

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

幸运的是，自Android API版本21以来，现在存在多dex支持。

您可以这样启用它：

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

来自Android开发者网站here的更多信息。

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。

Answer 2

失败原因位于构建输出的第二行 - "com.android.dex.DexIndexOverflowException: Cannot merge new index 68094 into a non-jumbo instruction!"

这意味着你的应用程序达到了最大方法限制，com.google.android.gms：播放服务很大（如许多方法）

最简单的解决方案是只使用您实际需要的Play服务组件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'

Android，Build Successful，但apk版本（后续运行）失败
