我正在尝试为我的 LibGDX 项目运行 Android 构建，但当构建尝试执行 android:transformClassesWithDexForDebug 时出现错误。我已经寻找这个问题的解决方案有一段时间了，但所有建议似乎都不起作用。我运行的是具有 16GB RAM 的 Linux 机器，因此 RAM 问题的介词不太可能。我已经为我的应用程序启用了 Dex，添加了 Dex 作为依赖项，降低了目标 SDK 版本，清理并重建了项目，重新启动了 Android Studio，重新启动了我的计算机，尝试了最新的 Android Studio 稳定版本和 beta Canary 9 版本，一切都无济于事。我收到的执行失败消息是:
Error:Execution failed for task ':android:transformClassesWithDexForDebug'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/programs/android-studio-preview/jre/bin/java'' finished with non-zero exit value 1
这是我当前的 android 模块的 build.gradle 文件:

我几乎尝试了编译 SDK 版本、目标 SDK 版本和最低 SDK 版本(从 21 到 25)的所有组合。我正在测试的手机是运行 API 级别 21 的 HTC One，并且没有可用的更新。话虽如此，问题可能出在我的手机上吗？还值得一提的是，不久前我能够在应用程序的早期版本上成功运行构建，当我恢复到该版本时，出现了同样的问题。同样，我已经提到了与此问题相关的所有其他 StackOverflow 线程，但到目前为止，没有一个解决方案能够解决我遇到的问题。还有什么我可以尝试的吗？
最佳答案
根据Android doc :
android {
compileSdkVersion 26
buildToolsVersion "21.1.2"
defaultConfig {
...
minSdkVersion 15
targetSdkVersion 21
...
// Enabling multidex support.
multiDexEnabled true
}
...
}
dependencies {
compile 'com.android.support:multidex:1.0.1' <-- Not required when minimum sdk is >=21
}
除了 build.gradle 中的修改您需要编辑 Manifest 文件以设置 android:name在 <application>标签如下:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<application
android:name="android.support.multidex.MultiDexApplication" >
...
</application>
</manifest>
