Error while building/deploying project testforandroid (kit: Android for armeabi-v7a,arm64-v8a,x86,x86_64 (Clang Qt 5.14.2 for Android))

When executing step "Build Android APK"

解决方法：

重要的是这一段，原因是因为路径 D:\project\program\Qt\testforAndroid\build-testforandroid-Android_for_armeabi_v7a_arm64_v8a_x86_x86_64_Clang_Qt_5_14_2_for_Android-Release\android-build\build\generated\aidl_source_output_dir\debug\compileDebugAidl\out\org\kde\necessitas\ministro\IMinistro.java 包含的字符太多了，超过了限制，尝试把文件夹的名字改短一点，具体是要小于252个字节，也就是最多251个字节，

其实最大限制是260，只不过这这个目录下需要生成两个文件，还有一个是：IMinistroCallback.java ，这个文件比 IMinistro.java多8个字节，所以上面这个就需要小于252个字节，

如果上面的满足，下面不满足，就会出现另一个错误

以上就是解决方法，下面是我的苦逼探索经历。
