Answer 1

对于那些将来会发现这个帖子仍在寻找答案的人（就像我一样）。

  

W / System：ClassLoader引用了未知路径：/ data / app /[...]/ lib / x86

是我在LogCat中唯一的错误/警告。在尝试了几乎任何事情后，在Android操作系统中清理应用数据（设置 - ＆gt;应用程序 - ＆gt; MyApp - ＆gt;内存 - ＆gt;清除数据）是唯一有效的解决方案。

我希望它对某人有帮助。

Answer 2

  

W / System：ClassLoader引用了未知路径：/data/app/com.pptsindia.feedapp-1/lib/x86

不是错误。这是系统发出的警告。

您的错误实际上有点低于：

  

致命的例外：主要

     

流程：com.pptsindia.feedapp，PID：3040

     

java.lang.RuntimeException：无法启动活动ComponentInfo {com.pptsindia.feedapp / com.pptsindia.feedapp.MainActivity}：android.view.InflateException：二进制XML文件行＃14：二进制XML文件行＃14：在课堂上输入错误at.markushi.ui.CircleButton

基本上，您的XML文件存在问题。

所以你必须继续阅读堆栈，以确保你找到问题的根源。正如您所看到的，logcat在其记录的每一行上都显示了一个前缀

  

  

• V - 详细（最低优先级）

  

• D - 调试

  

• I - 信息

  

• W - 警告

  

• E - 错误

  

• F - 致命

  

• S - 无声（最高优先级，无需打印任何内容）

  

有关Android Developer - Debugging log的更多信息。

修改

如果没有进一步的信息，就无法知道实际问题是什么。您必须提供XML文件，但在这种情况下，我建议您再打开一个问题。

Answer 3

在我的情况下，Android Studio 3.0中的即时运行。我已禁用它，我终于可以在调试模式下运行应用程序了！

看起来Instant Run还有错误......

要找到它：文件 - ＆gt;设置 - ＆gt;构建，执行，部署 - ＆gt;即时运行
