I have an Android app built using
Visual Studio. If I hit F5 to run it, it builds, deploys and runs just fine.
I now want to automate some UI tests so I took the
com.myapp-Signed.apk out of the
/bin/debug folder and copied it to my UI tests area. I then run the install via ADB against that APK and it installs without a problem, but when I launch it, I get a blank screen. No crash, no output, just a blank white screen.
If I attempt to install the other (unsigned) APK, I get the error:
Failed to install D:\myAppName\Artefacts\com.myAppName.apk: Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl1599731502.tmp/base.apk: Attempt to get length of null array]
So I'm assuming the signed .apk is the way to go?
If so, any ideas why I'm only getting a blank screen?
