Latest Android version does not install.
You might need to try the "com.andehpi.ac-70004-universal-release.apk".
If it still could not be work on your cellphone, you might need to Upgrade your Android system and Firmware version to the Newest one.
I have tested the "com.andehpi.ac-70001-universal-release.apk" (Version Itch-v0.7.00-1i) on my cellphone ( Android version 10 ), it works fine.
