Writing android gui using python(introduction)

PythonForAndroid provides support for python script language on android. CLE project supports interaction between python and java, gives a common interface for multiple programming languages. And wrapandroid project encapsulates android java class with cle objects. Using the three components, programmers can write android gui programs with python directly. This article is an introduction. There will have series of articles to further explain how to programming android applications using python.

Preparing environment.

install PythonForAndroid from http://code.google.com/p/android-scripting

CLE may install from network by application automatically, you need only include starcore_android_r5.jar in the project. The file is in starcore_devfiles_r5.zip, which can be download from http://code.google.com/p/cle-for-android

Wrapandroid has two files: wrapandroid.jar and SRPWrapAndroidEngine.xml, which can be download from http:/code.google.com/p/wrapandroid-for-multilaguage/download/wrapandroid_devfiles_0_8_1.rar

Begin programming

Open eclipse, create a new android project, for example, “introduction”

Add Permission, which is used to download and install cle for the application

 Collapse | Copy Code

    <uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

copy files : starcore_android_r5.jar and wrapandroid.jar into the project directory, and add them to java build path, as shown below.

copy file : SRPWrapAndroidEngine.xml to assets directory.

edit IntroductionActivity.java

import com.srplab.wrapandroid.*;

public class IntroductionActivity extends WrapAndroidActivity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        //setContentView(R.layout.main);

        StarActivity._Call("DoAssetsFile", "python", "code.py");

    }

}
