changing wallpapers automatically in android

Question

hi, i am new to android programming and want to develop an application similar to vista where the wallpaper changes automatically , so how should i go about it, please could someone guide me on it? thanks

Answer 1

You would need to use the Wallpaper Manager Api : http://developer.android.com/reference/android/app/WallpaperManager.html

Here is a related tutorial : http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/SetWallpaperActivity.html

Basically, you will have to use the WallpaperManager class which provides the neccesarry methods to do so.

Also, don't forget to add the SET_WALLPAPER permission to your AndroidManifest.xml:

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.SET_WALLPAPER" />
</manifest>

Edit: take a look of the example that Ravi Vyas gave you... I didn't know about it and it looks pretty useful.

thanks for that, i have created a layout,having three buttons for choosing the wallpapers i want to use for the app , one for setting the time interval and the 3rd one for resetting. so for the choosing wallpaper button how do i make the user select the desired wallpapers? Also for setting the time , i need to take input from the user time interval(in seconds) during which the wallpaper changes . So, how should i go about it?

For the time button i tried the following ,but gives error:

 .....
case(R.id.timeButton):
         //get user input
         AlertDialog.Builder alert = new AlertDialog.Builder(this);
         alert.setMessage("Enter the time interval");

         //using EditText to get user input
         final EditText edit = new EditText(this);
         alert.setView(edit);

         //set the +ve and -ve buttons for alert
         alert.setPositiveButton("OK", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
            Timer ti = new Timer().scheduleAtFixedRate(Activity.WALLPAPER_SERVICE, 0, edit.getText());  //ERROR HERE
                //what activity should i set here? so that all the wallpapers selected are shown after 3 secs interval
            }
        });
