Deploying to Android results in file not found after adding QtQuick Controls

Question

After importing QtQuick.Controls 1.2 and using StackedWidget component, I now get an error when deploying to Android as seen below. The missing file AnimationDrawable.qml is not missing from the Android build directory so I do not understand why it is not packaged with the APK.

It deploys fine when I remove the imported QtQuick.Controls and replace the StackView with something else.

My Qt version is 5.4.2.

I tried deploying it with Qt 5.3.2 and it works as expected.

Answer 1

When deploying the application, androiddeployqt will copy a bunch of files which terribly fails on Windows when source or destination paths become longer than 260 characters (yeah, that's a "known feature"). Keeping the Qt installation and the project directory as top level as possible helps to reduce the path lengths and solves the problem. And that's basically it!
