Warning: AndroidManifest.xml already defines versionCode

Question

Can anybody explain this error to me?:

Warning: AndroidManifest.xml already defines versionCode (in http://schemas.android.com/apk/res/android); using existing value in manifest.
Warning: AndroidManifest.xml already defines versionName (in http://schemas.android.com/apk/res/android); using existing value in manifest.
Warning: AndroidManifest.xml already defines minSdkVersion (in http://schemas.android.com/apk/res/android); using existing value in manifest.
Warning: AndroidManifest.xml already defines targetSdkVersion (in http://schemas.android.com/apk/res/android); using existing value in manifest.

I'm building from within a full Android source base, and there's an Android.mk file being used for the build.

The resulting apk seems healthy enough, but I don't like unexplained warning messages in my builds.

I've searched up and down my source tree and those four variables are defined nowhere but in my AndroidManifest.xml file.

Answer 1

in Android Studio these variables are defined in build.gradle file

    defaultConfig {
    applicationId 'org.example.'
    minSdkVersion 11
    targetSdkVersion 21
    versionCode 1
    versionName "1.0 Beta"
}
