Python SL4A Development

Good. I feel like a frustrated idiot. I want to say that in advance.

I am trying to configure Python / Android so that I can develop Python applications for Android. I have both SL4A and the Python interpreter installed on my Android device, and you can write an application on the phone that works.

The problem is how I can continue development on my PC and interact with my Android device. I unpacked the add-on package and put it in $ PYTHONPATH / site-packages /. I enabled Ecplise with PyDev and Android packages and set the AP_PORT and AP_HOST environment variables.

When I run the following code:

import android droid = android.Android() droid.makeToast("Hello")

I get errors in Eclipse that include "com.googlecode.android_scripting.rpc.RpcError: Unknown RPC". to bad magic numbers.

When I go to Python through the CLI and click

 import android

I get the following output

 com.googlecode.android_scripting.rpc.RpcError: Unknown RPC.

Any help or primer will be greatly appreciated.

I know that I have to do something wrong, because I see that others are being tuned, what appears is relative ease.

Thanks in advance.

1. Start the server

On device

First connect the device to USB. Then, for remote debugging, you need to start the server on your device:

 SL4A -> Interpreters -> Menu -> Start Server

Private is preferred.

Then you can see the port for the server in the Android notification area (with SL4A r5 you can specify a fixed port in the settings).

From PC

Alternatively, you can start the server from a PC using adb using a specific port (r5 required to install the port):

 $ adb shell am start -a com.googlecode.android_scripting.action.LAUNCH_SERVER \ -n com.googlecode.android_scripting/.activity.ScriptingLayerServiceLauncher \ --ei com.googlecode.android_scripting.extra.USE_SERVICE_PORT 51943


2. Specify the connection

Now you need to forward your port using adb (assuming the search value is 51943):

 $ adb forward tcp:51943 tcp:51943 $ export AP_PORT=51943


3. Start the script

After that, you can run the script locally:

 $ python my_script.py


Wifi connection

If you want to go over Wi-Fi, you do not need to forward the port using adb . Instead, you should use a public server and optionally specify your host:

 $ export AP_HOST=192.168.0.100
