我的应用程序无法构建，因为以下logcat错误，我甚至不明白

Question

这是logcat。我需要澄清这个错误，请社区

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: `com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexIndexOverflowException: me`thod ID not in [0, 0xffff]: 65536

我做了更改，但我再次得到这个错误？？

Answer 1

请参考这个。原因是您已经超出了方法限制。这主要是由于使用google-play-services或任何其他大型图书馆。如果使用google-play-services，请尽量只使用必需的组件。单个库的列表可以在这里找到
