I also want to see with it what is possible with python on this device, and if perhaps I can port a part of Gramps to there. Well, it will not be easy it seems, but something is possible. I'm thinking about an reader that can understand the Gramps xml fileformat.
So, what is needed to try things out?
- SL4A (scripting layer for android), so download it on your phone by clicking the barcode on : http://code.google.com/p/android-scripting/
Then when downloaded, go to downloads on your android phone, and click the download to install it. - Next, install python for SL4A, latest version of PythonForAndroid from http://code.google.com/p/android-scripting/downloads/list
Again, click it in the Downloads to install it, then open run in and the app you see will have an install button at the top. Click that to install python and extra python modules/scripts - You are now ready on your phone, click the SL4A app and you will see a list of scripts, click one to run it in a terminal or run it standalone
- To develop, you need to have a good PC/laptop, and install the android emulator there. Follow eg the walkthrough on this blog. So download the SDK, install it, and run it by typing in the tools directory
./android, then in the emulated phone, install again SL4A and python4android. - Write a script on your PC. Eg, I write an application in
~/gramps/android
push it to the open emulated android, go in the platform-tools directory from the SDK and run./adb push ~/gramps/android/ /sdcard/sl4a/scripts/
- On the emulated phone, you will see the script in SL4A, and you can click it to run it.
- Once your script is not crashing your emulated phone anymore, you can push it to your actual phone: connect the phone to your PC in usb-mode, and move the file to /sdcard/sl4a/scripts/ on the phone. You can now run it in SL4A on the actual phone.
