I was trying to upload my APK having targetSDK version as 30 on Google Play store but it is restricting me to upload the APP and giving error "you uploaded an APK with an invalid signature error from APK signer error minimum signature scheme for target SDK" . Please help me with this issue. My Project is in Eclipse and I build my APK from Eclipse itself.
You should sign your APK with apksigner (https://developer.android.com/studio/command-line/apksigner), not jarsigner, and ensure to enable v2 signing, which is required in targetSdk 30.
