Even aapt2/aapt reports the duplicate. So this must be a form of obfuscation/trickery.

➜  2664 aapt2 d xmltree 2664.apk --file AndroidManifest.xml | more

➜  2664 aapt d xmltree 2664.apk AndroidManifest.xml | more

  N: amazon=http://schemas.amazon.com/apk/res/android
    N: android=http://schemas.android.com/apk/res/android
      E: manifest (line=2)

I'll have to test out patch that records the value of the namespace and skips an entry if it already exists.
