    @InsideFPV said in QGCS error for Android:

    i have to add libpng in my project but i didnt added that till now

    You DID add it already! Just look at your CMakeLists.txt file.
    I repeat the questions you did not answer:
    Was libpng found when running cmake?
    Where is libpng for Android located?

      @InsideFPV If Android NDK does not provide it you will have to build it by yourself from source.

                You're missing libjpeg library now. Install it.

                          @InsideFPV Maybe you should ask QGCS project? It is not part of Qt...
