Python for android: mediaPlay (url) is useless. What should I do?

 

You can write it in this way.

Play. py

 

# -*- coding: utf-8 -*-import androidimport osdroid = android.Android()path = u'/sdcard/sl4a/test.mp3'url = u'file://' + pathif os.path.exists(path):    droid.startActivity('android.intent.action.VIEW',url,'audio/mp3')else:    print path,'not exists'

A practical example of mplay. py in the reference book

 

import androidimport os, sysdroid = android.Android()# Specify our root directory and make sure it exists.base_dir = '/sdcard/sl4a'if not os.path.isdir(base_dir):    print base_dir,'is not dir'    sys.exit(4)def show_dir(path=base_dir):    Shows the contents of a directory in a list view.    # The files & directories under path.    nodes = os.listdir(path)    # Make a way to go up a level.    if path != base_dir: nodes.insert(0, '..')    droid.dialogCreateAlert(os.path.basename(path).title())    droid.dialogSetItems(nodes)    droid.dialogShow()    # Get the selected file or directory.    result = droid.dialogGetResponse().result    droid.dialogDismiss()    if 'item' not in result:        return    target = nodes[result['item']]    target_path = os.path.join(path, target)    if target == '..': target_path = os.path.dirname(path)    # If a directory, show its contents.    if os.path.isdir(target_path):        show_dir(target_path)    elif os.path.splitext(target)[1].lower() == '.mp3':        url = 'file://' + target_path        print url        droid.startActivity('android.intent.action.VIEW',url, 'audio/mp3')    # inform the user.    else:        droid.makeToast('Only .mp3 files are currently supported!')        show_dir(path)if __name__ == '__main__':    show_dir()
