Appcelerator Titanium Android Woes on Mac OSX

I have been having ongoing problems getting Appcelerator to build and install Android Apps again.

The very first time I built an Android App it took me some time to get the configuration right. Now that I have been through system upgrades I seem to have come back to step one again. Like before the official Appcelerator Guide helps me refresh how you get the device itself configured. However, it will not prepare you for the grand cluster of configuration issues you will face getting all the toys to play nicely together.


Appcelerator does not recognize your android device.
Even though if you run adb devices you can see it listed.


I still don't have a solution for this (most people suggest uninstalling everything and starting again, which to my mind constitutes giving up not solving it). I do have a work around though: Build the app without installing it and then use adb to install it independently. This definitely works in the absence of a better solution.

To build

Try the command titanium build,
- or -
Just use the distribute app dialog in Titanium Studio.
You can generate a signed APK easily this way.

To install

Just use the adb command line utility:

   adb install ../Desktop/MyApp.apk

Problem solved,... sort of.


adb does not even recognize your android device.
This seems to happen randomly, depending on what I had for breakfast.


I generally find this requires a little fiddling around. This particular combination is currently working for me:
1) Unplug your device.
2) Kill the adb server.
3) Plug your device back in
4) Run adb devices
This seems to kickstart the adb server in such a way that it correctly finds the attached devices.


Your android App almost builds an APK but red errors flash up at the end. Appcelerator tells you it was built but there is nothing in the build directory. You see a bunch of uninformative python errors codes referring to problems with the file:, for example:

line 2528, in <module>
[ERROR]     builder.build_and_run(False, avd_id, debugger_host=debugger_host, profiler_host=profiler_host)

For me it turned out that this is all because of the fact that some executables got moved around between distributions of the android SDK.

This problem is outlined in this note from the Appcelerator forums fixed it for me.


Create symlinks to aapt and dx in /Applications/Android-sdk/platform-tools:

ln -s /Applications/Android-sdk/build-tools/17.0.0/aapt aapt

ln -s /Applications/Android-sdk/build-tools/17.0.0/dx dx
