What's platformBuildVersionCode and platformBuildVersionName in Extracted Apk's

platformBuildVersionCode overrides and takes precedence over android:targetSdkVersion in the merged AndroidManifest. This is evidenced in the following android git commit: https://android.googlesource.com/platform/frameworks/base/+/ad2d07d

platformBuildVersionCode is added by a compiler, and means a version of targetSDK
platformBuildVersionName is a readable version name of targetSDK version.

After a long analysis, i got solution,platformBuildVersionCode is targetSDKVersion and platformBuildVersionName is version name of targetSDK(like Android 6.0) which are mentioned in build.gradle.
