Hi,
thank you for the project files you sent via email. We could initially reproduce the problem and were also able to fix it. We found a faulty configuration in the AndroidManifest.xml file:
All Qt-related projects usually include the line:
<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="14" />
(so our wizards do). In your project configuration you’re missing the “targetSdkVersion” attribute, Android then uses the provided min sdk version number, which results in API 9 for your project. This version is missing the required application state handlers and therefore the background music resumed playback.
Please make sure to define a target sdk version of 14 or higher and test it again.
Cheers,
Alex
