mag*_*hro 8 debugging build android-studio
我知道已经有很多关于此错误的变体问题，但到目前为止，没有一个问题对我有帮助。我是 Android 开发新手，对分散在整个项目中的众多文件感到迷失。
我正在关注https://www.youtube.com/watch?v=RcSHAkpwXAQ上的第一个（书籍）项目，该项目成功运行。然后，我创建了一个新项目，并按照相同的步骤（再次观看视频）但在我自己的应用程序中进行了活动。当我尝试构建它时，出现了 2 个对我来说意义不大的错误。我不知道其中一个是否会导致另一个，或者首先关注哪一个。也不告诉我在哪里寻找问题。
任务 :app:mergeDebugResources FAILED 任务“:app:mergeDebugResources”执行失败。执行com.android.build.gradle.internal.res.ResourceCompilerRunnable时发生故障资源编译失败。检查日志以获取详细信息。
ParseError at [row,col]:[1,1] 消息：序言中不允许出现内容。
第二个显然是由于 xml 文件之前的不可见字符造成的，但我如何知道是哪一个呢？
第一个建议我运行堆栈跟踪，我已将其包含在下面。我不认识第一部分中的任何内容。第二个再次表示我在序言中有内容，但引用了 sun.com 上的 java.xml，它看起来像外部文件。
我非常感谢任何关于如何使用调试器的建议，特别是关于查找和解决此问题的建议。让我知道是否需要包含任何特定代码来提供帮助。

我现在也遇到了同样的问题，除了我的问题是 [8,10] 行。
在过去的一个小时里，我痛苦地检查了我的 android 项目中的每个 xml 文件，最后发现了我的activity_main2.xml文件中的一个错误。
由于某种原因，我不小心<?xml version="1.0" encoding="utf-8"?>在第 8 行和第 1 行中输入了内容。我将其从第 8 行中删除，然后就不再出现该错误了。
显然，您的问题很可能出现在不同的 xml 文件中。只要确保检查所有内容中它告诉您的内容即可。令人沮丧的是，Android Studio 没有向我们显示直接错误在哪里。祝你好运
