Hello all,

My current QML app contains a few components, .wav files, and two .png images and works well and is installed on many Android devices from my old HP tablet, running Android ver 4.4.2, to my friends' smartphones running an updated version of Android.


But on many other Android devices cannot be installed, yet!


What could be the problem in your perspective, please?
I use this version of NDK: "android-ndk-r19".
I'm not sure but can it be the reason for the problem, please?


Is there a popular/prevalent version of NDK (or even JDK) that works well on most Android devices, please?
