When I try to install an unsigned release app
adb install android-build-release-unsigned.apk |
I get
1 2 | Performing Streamed Install adb: failed to install android-build-release-unsigned.apk: Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl827870317.tmp/base.apk: Attempt to get length of null array] |
And switching this off does not help:

But debug apps install successfully:
