where user_name and password are strings that are provided by the app user during the app install. Assuming the service name is MyService this creates a registry key HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\_SC_MyService that is hidden by default and even administrator does not have a permission to read it and regedit does not show the content of HKEY_LOCAL_MACHINE\SECURITY key by default. But fortunately the access can be allowed by right clicking on HKEY_LOCAL_MACHINE\SECURITY and selecting Permissions or alternatively by running
in PowerShell. To list the content of the key I used the following command:
My Windows 10 PC started to glitch a little bit and I scanned its disks with the following commands:
chkdsk C: /f /r /x
The type of the file system is NTFS.
Cannot lock current drive.
Chkdsk cannot run because the volume is in use by another
process. Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N) y
This volume will be checked the next time the system restarts.
I keep working on my Lines Game and probably I try to make it the best Lines Game in the world, but there is some disappointing incident that prevents it from being the best and makes it a usual game that glitches a bit. To see the glitch in action download the beta version of the game.
Adding Interstitial Ads to a QT application on Android platform is an interesting and relatively exciting job. I learned the following facts while doing it:
To build my app with Google Play Services I add com.google.android.gms:play-services-ads:18.1.1 dependency to build.gradle and add com.google.android.gms.version and com.google.android.gms.ads.APPLICATION_ID to the manifest.
I do not specify additional permissions (uses-permission attributes INTERNET, WRITE_EXTERNAL_STORAGE, ACCESS_NETWORK_STATE) required by ads, but they are detected automatically when I upload the app to Google Play store and the used is not prompted to allow them when the app starts.
QT main thread (on which QML UI is run) is not Android UI thread. So I cannot call Java advertising API from QML or C++ directly, but all the calls should be queued with runOnUiThread method.
To access Context required by Java advertising API I replace QtActivity with my own custom activity that implements all the advertising logic and forwards all the lifecycle events to original QtActivity.
When the interstitial ad is open my activity is paused and stopped (onPaused / onStopped event handlers are called in Java and onApplicationStateChanged with Qt::ApplicationInactive / Qt::ApplicationSuspended respectively ) and when the interstitial ad is closed my activity is resumed but in different ways either with onRestart.
