Description
When an Android application is set to allow the QtEvent loop to run while the application is in the suspended state, calling QtAndroid::runOnAndroidThread events get queued and calling QtAndroid::runOnAndroidThreadSync will in turn cause Qt's main thread to then be blocked.
In the below code snippet, it is queueing based solely on if the activity is paused, I believe it should also check for the background_running value set in the Android manifest as well.
private static void runPendingCppRunnablesOnAndroidThread() { synchronized (m_mainActivityMutex) { if (m_activity != null) { if (!m_activityPaused) m_activity.runOnUiThread(runPendingCppRunnablesRunnable); else runAction(runPendingCppRunnablesRunnable); } else { final Looper mainLooper = Looper.getMainLooper(); final Thread looperThread = mainLooper.getThread(); if (looperThread.equals(Thread.currentThread())) { runPendingCppRunnablesRunnable.run(); } else { final Handler handler = new Handler(mainLooper); handler.post(runPendingCppRunnablesRunnable); } } } }
