I use PhoneGap / Cordova to create an Android app with a screensaver containing a centered logo.
Here is what I did:
In my Android Manifest.xml, I added
<preference name="SplashScreen" value="splash" />
<preference name="SplashScreenDelay" value="5000" />
Then I used a nine-track image generator here to create 9-patch images for the screensaver. The goal is to constantly place the logo in the center. When loading an image, it looks as follows. I saved the editing mode "stretch sections".

The problem is that the splash of the image is stretched all the time. This means that the logo (blue box) is disproportionate.
I checked the solutions here Screensaver with the plugin Corona / PhoneGap 9-patch , but this did not help.
9-- Android, ?
