Android Tips

These classes haave been implemented by using Java to work on Android OS (tested on 2.3).

• Implementation of timer on Android using "Handler"
  • Class: TimerHandler.java ( 675 bytes)
  • Example: TimerHandler.zip ( 53,791 bytes)
• fileUpload.java ( 4,017 bytes) are from "http://reecon.wordpress.com/2010/04/25/uploading-files-to-http-server-using-post-android-sdk/" with minor modifications. One uploads a file to server and the other uploads a buffer (array of bytes) to server.

These are some solutions to certain problems.

• On March 2012, my "HttpURLConnection" has the problem on the new Galaxy Nexus (Android 4.0 ICS). I found from here that I need to put "StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().permitAll().build());" in the main thread.
