application = webapp.WSGIApplication(
[('/', UnangPahina),

def main():
run_wsgi_app(application)

if __name__ == "__main__":
main()




Note:

After compile the code and save do the following:

Go -> Application - Terminal

Type the command

/* compile the python file that you created and compile by Google App Engine
chmod u+x progname.py

run the script

./programko.py

Build Android application in Windows and Linux ^_^

Step 1: Generate Resource java code and packaged Resources
aapt package -f -M ${manifest.file} -F ${packaged.resource.file} -I ${path.to.android-jar.library} -S ${android-resource-directory} [-m -J ${folder.to.output.the.R.java}]

Step 2: Compile java source codes + R.java
use javac

Step 3: Convert classes to clear bytecodes
use dx.bat
dx.bat –dex –output=${output.dex.file} ${compiled.classes.directory} ${jar files..}

Step 4: Create unsigned APK
use apkbuilder

apkbuilder ${output.apk.file} -u -z ${packagedresource.file} -f ${dex.file}

or

apkbuilder ${output.apk.file} -u -z ${packagedresource.file} -f ${dex.file} -rf ${source.dir} -rj ${libraries.dir}

-rf = resources required for compiled source files?
-rj = resources required for jar files

Step 6: Generate a key
use keytool

Step 7: Sign APK
use jarsigner

jarsigner -keystore ${keystore} -storepass ${keystore.password} -keypass ${keypass} -signedjar ${signed.apkfile} ${unsigned.apkfile} ${keyalias}

Step 8: Publish
use adb
adb -d install -r ${signed.apk}

Inspecting your APK file:

aapt list -v latest.apk
