用于Android调试的Qt问题

Question

我已经在Qt中安装了一个工具包来将我的应用程序部署到Android上。查看了issues，最后得到了：

• Qt Creator 4.3.1
• Qt 5.9.1
• NDK: r10e
• SDK: r25.2.5

我部署到运行Android5.1.1的平板电脑上。

“跑”很好。我的应用程序是部署、启动和崩溃的。因此，我想调试，但不太顺利。在我的应用程序启动之前，我得到了“连接到远程服务器失败:附加到进程6285失败”的错误。

Answer 1

尝试如下:获取应用程序的安装文件夹：

adb shell run-as <package name of your app> /system/bin/sh -c pwd

然后更改该文件夹上的文件属性：

adb shell run-as <package name of your app> chmod "a+x"  <output of previous command>

您可以从android清单文件中获取您的包名。在此之后，Qt的调试应该可以正常工作--或者对我来说是这样的。
