8. Build directory

(1) It is recommended to change the name of the build directory to a shorter one, because if the folder name is too long, it will not compile.

9. Code testing

(1) Output the C++ standard used by the compiler (201707)

qDebug() << __cplusplus;

10. Error reporting and resolution

(1) If an error "android:exported..." is reported during the compilation process, add android:exported="true" to the <activity> of the AndroidManifest.xml file:

<activity android:exported="true" ............
