Description

When an Android QtService is started, the screen goes black and a

QEGLPlatformContext: eglSwapBuffers failed: 300d

error is produced repeatedly (twice in provided example). The app eventually crashes. This occurs consistently when the service is started.

My intent is to keep a QTimer, QTcpSocket and QLowEnergyController running in the background when the app is closed. So far only running a QtService has allowed this. The socket is kept open, but the app goes black and eventually crashes. Any help is greatly appreciated (including alternatives, if available).

A bug report log is available upon request (too large for bug tracker).
