    1. first add camera uses permission in manifest file…and add external storage in manifest file ….this is important step for create the camera applications….

  1. camara work is done.. 😀 i found it
    now i want to know how to decode json string

    [{“Status” : “Success”,”Values” : {“age” :25, “name” : “demo”, “address ” : “tokya”}]

    this is my string
    iwant to decode that please need a help

  2. Perfect. This is exactly what I was looking for. The app I’m making requires six of these, three for variables, three for RGB settings. I suppose a little finagling with the math will allow me settings from 0-255.

    Thank you very much for this!

  3. I’m trying to use a SeekBar and display the current progress of it below it in a TextView, but for some reason, when I try to use the getProgress() method, I get a weird force close error. Could you maybe show an example of doing that? Or is there an easier way?


    1. Hey Patrick:- What are you getting the reason for force close in the LogCat. Please paste it here, then I can help you.
      I tried it and I had no problem. or Put a try catch around it and print out the message inside catch.
      Anyway check the latest post for your problem.

  4. Everything works fine in your demo UNTIL I drag the 1-2 TextViews *ABOVE* the SeekBar.

    Then the app crashes. Why would the “placement” matter in such a drastic fashion?
