Worked on this one for a few days. The fix was to:
- Move the <uses-sdk> tag to the top.
- Move all the <uses-permission> tags under the <uses-sdk> tag.
- Remove the empty <uses-configuration> tag (probably the main culprit anyway).
Google – you really need to fix your system. “The server could not process your apk. Try again” is not anywhere near a helpful error message.
I hope this helps anyone running into this problem!
