While writing a quick test ADF Mobile app to verify a new training pc, I ran into an ADF Mobile deployment error below:
Cannot run program "... platform-tools\aapt"
CreateProcess error=2, The system cannot find the file specified.
Update (05/21/2013): Per Chris Muir, ADF Product Manager, this issue has been officially logged at Oracle as a bug 168376554. They're working on it!
This started happening because Android SDK Tools was updated from Rev. 21.1 to Rev 22.
What revision 22 did was it moved aapt.exe to a different directory. The catch is that you can't configure or tell JDeveloper where to find this.
To fix the issue, I took my SDK version back to Rev. 21.1, by extracting the Rev 21.1 zip and using that one. I did have to re-install/load the Android API, but 10 minutes and i was back in business. However, if you want use Rev 22, copy the contents of %SDK_Home%/build-tools/android-4.2.2 to %SDK_Home%/platform-tools. The only downside of this, is that Android SDK won't be able to maintain/update the platform-tools section. Which is why i'm using Rev 21.1 - theres nothing significant that you're missing by sticking with Rev. 21.1 vs Rev. 22.
Until Oracle changes how JDeveloper can find these libraries, you can use this workaround!
