Trying to upload apk with v1 signature only with the below command, to sandbox environment but it gives me error like 'oops invalid file' - no other clear message, I hope if there is any package name conflicts, then it will give me some kind of message at least
apksigner sign --ks /Users/deepakrathi/clover/clover-sandbox --v1-signing-enabled=true --v2-signing-enabled=false /Users/deepakrathi/Android_Projects/loyaltydog-clover/app/build/outputs/apk/sandbox/release/app-sandbox-release-unsigned.apk
