有人能帮我解决这个问题吗?tnx

Answer 1

添加google地图后，方法和引用计数超过64K:

错误:.dex文件中的方法引用数不能超过64K.

这是一个大问题，每个大项目都会遇到这样的问题。但谷歌给出了一个解决方案:配置超过64K方法的应用程序。

Answer 2

根据你的问题

代替

compile 'com.google.android.gms:play-services:9.4.0'

使用这个

com.google.android.gms:play-services-maps:9.4.0

这将只包括地图所需的游戏服务。你的代码将导入所有的游戏服务包，这将导致你的应用程序跨越64K方法限制

Answer 3

将其添加到构建中。在buildTypes{…}:

 dexOptions {
    javaMaxHeapSize "4g"
}

Answer 4

将此依赖项添加到gradle…您的应用程序已达到64k参考限制。这里有更多

compile 'com.android.support:multidex:1.0.0'

还要加上

android {
    defaultConfig {
        // Enabling multidex support.
        multiDexEnabled true
}
}

Answer 5

根据Google的建议:选择性地将api编译到您的可执行文件中，您可以尝试在构建中替换以下行。gradle文件:

compile 'com.google.android.gms:play-services:9.6.1'

与你需要的:

compile 'com.google.android.gms:play-services-maps:9.6.1' compile 'com.google.android.gms:play-services-xxx2:9.6.1' compile 'com.google.android.gms:play-services-xxx3:9.6.1'
