Python On Android SDK
Following steps will lead to the installation of python interpreter on Android SDK.
Step 1: Add the path of tools directory to the environment
Add the path of the directory ‘andoid-sdk/tools’ to the path variable by executing the command
$PATH = $PATH:path_of_android-sdk/tools/
Step 2: Create a SDCARD for storing application on Android.
As Andoid API 2,.2 allows the user to save applications in sdcard insted of using the phone’s memory .So for that purpose a SDCARD of apprpriate size has to be created by executing the command
mksdcard ‘size’M ‘ sdcardname’
This creates a sdcard of size of ‘size’ MB with name as ‘sdcardname’ .
Step 3: Download the package from the following link
Download the SL4A from http://code.google.com/p/android-scripting/downloads/list .
Step 4: Start the Android SDK and install the SL4A
Open the terminal and Start the Android-SDK by executing a command like
emulator @’avd-name’ -sdcard ‘sdcardname’
now without closing this start a NEW terminal and install the sl4a package downloaded earlier by executing the command .
adb install ‘sl4a_rx.apk’
now the icon for sl4a can be seen in the menu of SDK .
Step 5: Installing python from SL4A.
Now the python interpreter is to be selected in Sl4A . After clicking on the SL4A icon , click on the menu button on the SDK and then click on ‘View’ button on screen .
then among the list displayed under the ‘View’ button click on the ‘Interpreter’
then among the list of Interpreter’s select Python.
it will download python interpreter and install it.
finally the interactive python shell can be seen on the ‘Android SDK’.
This was helpful to me as my B.tech major project was to develop a Scheme to Python compiler for Android Simulator. So for that purpose it was necessary to get an environment setup where python code can be run for Android OS.
