AndroidStudio调试器突出显示了错误的行-AndroidStudiodebuggerhighlightsthewronglines

This is a problem with dx, which is the part of the build that turns your Java .class files into .dx files for packaging into Android. According to this:

这是dx的一个问题，它是构建的一部分，将Java .class文件转换成。dx文件，用于打包到Android。根据这个:

https://code.google.com/p/android/issues/detail?id=34193

if a function has multiple return paths, dx merges the return instruction into a single return instruction, so during debugging, the debugger can't tell which line a return belongs to and things jump around. This corresponds to what I see when I try to reproduce your problem: each time through the loop it does the if (a == 3) check, jumps to the return 0 at the end, and then jumps back into the loop. You're seeing that last return 0 get merged with the return retval in the middle of the loop.

如果一个函数有多个返回路径，dx将返回指令合并到一个返回指令中，因此调试期间，调试器无法知道返回是属于哪一行的，事情就会跳来跳去。这与我尝试重现您的问题时看到的情况一致:每次循环执行if (a == 3)检查时，在结束时跳转到return 0，然后跳转回循环。您将看到最后一个return 0与循环中间的return retval合并。

I doubt this will be fixed any time soon, so you may just have to learn to live with it. Sorry, I know it's kinda crazy.

我怀疑这个问题不会很快得到解决，所以你可能得学着适应它。对不起，我知道这有点疯狂。

Try Build -> Rebuild project and then Shift + F9. You have outdated code running on application.

尝试Build ->重建项目，然后Shift + F9。在应用程序上运行过时的代码。

Here's what worked for me, at least for stepping into Android SDK source code:

以下是对我有用的东西，至少对于进入Android SDK源代码来说是这样的:

1. Install the SDK Platform and Sources for Android SDK for exactly the API level of the version of Android you are running during development (use the Android version history page to find out which API level your device has).
2. 为Android SDK安装SDK平台和源代码，以获得在开发过程中运行的Android版本的API级别(使用Android版本历史页面来查找设备的API级别)。
3. Compile your app for exactly that version. For example, in Android Studio, open your app's build.gradle file and set the value of compileSdkVersion accordingly.
4. 为这个版本编译你的应用程序。例如，在Android Studio中，打开应用程序的构建。渐变文件，并设置相应的编译dkversion的值。
5. Debug your app. When you step into Android SDK source, you should see the correct line.
6. 调试你的应用程序。当你进入Android SDK源代码时，你应该看到正确的路线。
7. (optional) Recompile with the latest SDK before deploying. In other words, change compileSdkVersion back.
8. (可选)部署前使用最新的SDK重新编译。换句话说，更改编译回dkversion。
