Failed to find resource file (Mmiap.xml} error because the SDK for moving mm puts some resource files in the jar package, causing unity to be unrecognized
You need to do the following steps:
--Unzip Mmbilling.2.3.0.jar, extract Copyrightdeclaration.xml, Mmiap.xml, version file, and Mmiap folder
--Copy the Mmiap folder to the Unity Project Assets/plugins/android/assets directory, then package
--playing apk due to lack of the above three files still can not run, with the decompression software (I am Mac system, with Betterzip, if it is windows, optional 7-zip) Open the APK, delete the signature file inside Meta-inf, Drag the Copyrightdeclaration.xml, Mmiap.xml, and version files extracted above to the inside.
--Re-sign: Because the above APK signature has been destroyed, we need to re-sign, Jarsigner-verbose-keystore./my.keystore-storepass <password>-signedjar. signed.apk./unsigned.apk <aliasname>, creating signed.apk after re-signing
