error trying to build for Android

mzimmers

Hi all -

Several months ago, I (successfully) built an app for Android. (It also runs on Windows, and eventually Linux.) I thought I kept complete notes on the steps necessary to do this, but I must have left something out, because I'm trying to create a new project for Android, and I'm getting this error when I try to build:

:-1: error: Cannot find application binary in build dir C:/Users/Michael.Zimmers/Qt_projects/build-colors-Android_Qt_6_5_2_Clang_arm64_v8a-Release/android-build//libs/arm64-v8a/libappcolors_arm64-v8a.so.

I guess I'm curious why the build would be looking for a .so file named after my project when it hasn't built anything yet.

Thanks for any enlightenment...

Well, for lack of anything else to try, I closed the project, manually deleted the build folders and my CMakeLists.txt.user file, and reconfigured. Now it works.

I guess you build your app as .so(not executable) for Android. That dir is where your app so is located. If it is not found, that means your build failed.

Any other error or warning messages?

No. And this message shows up immediately upon starting a build.

I went through my first project makefile and didn't find much that had to do with Android; what I did find, I replicated in my new project:

set( ANDROID_PACKAGE_SOURCE_DIR ${PROJECT_SOURCE_DIR}/android CACHE INTERNAL "" )
set_property(TARGET appcolors APPEND PROPERTY
    QT_ANDROID_PACKAGE_SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}
)

So...I'm not really sure what to try next...
