Error when compiling apk - unable to find valid certification

Hello,

It has been roughly a year since I've exported an apk, and have never had an issue before. Recently tried exporting an apk from a project I've had no problem exporting from several times in the past and got this error, though:

A couple of notes, I am not on a secured network, nor using a proxy or VPN.

I'm using CF 2.5 R295.10 and have just updated Android Studio to the latest jellyfish version.

My Pathname of the JDK directory is pointing to jdk1.8.0_65, and the Pathname of the Android SDK directory is \AppData\Local\Android\Sdk

Any help would be much appreciated!

Thank you for the quick response, Fernando!

Ok, we're getting somewhere! It seems that resolved my initial issue, but now I'm getting a different error:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

My Build API is set to 29, with minimum Android version set to 4.4 and Target Android Version set to 8.0

Display Mode is OpenGL ES 1.1 though i'm not sure if that has to do with anything.

EDIT: And solved! I followed Linky's advice from another thread, and changed my settings as such:

App Android properties:

• Build API: 33
• Minimum Android version: 5.0
• Target Android version: 13.0

Thanks again!
