Environment

• Android 5.0 @ Samsung Galaxy 5


• ADB @ Windows (x64)


• Native ADB Commandline tool


• C++11

Problem description

The application process exit although the spawned thread was de-touched ( 'adb -d shell ps | findstr shell' shows no process running )

Code snippet

AddRef();
__android_log_print(ANDROID_LOG_INFO, "MySvc", "\n\nBefore thread start\n");
m_threadMainLoop = std::thread([this]() {
    __android_log_print(ANDROID_LOG_INFO, "MySvc", "thread start\n");
    HRESULT hr = m_spIOCP->DoModal();
    OnCleanup(hr);
    Release();
    __android_log_print(ANDROID_LOG_INFO, "MySvc", "thread exit\n");
});
m_threadMainLoop.detach();
sleep(2);// w/o sleepping the will thread never start ( although it's detached )
__android_log_print(ANDROID_LOG_INFO, "MySvc", "After detach\n");
///////////////////////////////////////
// Main process thread will now exit //
///////////////////////////////////////
