Q:

What's platformBuildVersionCode and platformBuildVersionName in Extracted Apk's

Extracted an Apk using APKTool getting the manifest.xml like this,
<manifest xmlns:"http://schemas.android.com/apk/res/android" 
android:versionCode="31" 
android:versionName="3.1" 
package="xxx.xxx.xxx" 
platformBuildVersionCode="22" 
platformBuildVersionName="5.1.1-1819727">
<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="22" />

Need to know what's platformBuildVersionCode and platformBuildVersionName
Already Checked this,What is "platformBuildVersionCode" in AndroidManifest.xml?

A:

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

A:

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.

A:

platformBuildVersionCode overrides and takes precedence over android:targetSdkVersion in the merged AndroidManifest.  This is evidenced in the following android git commit:
