I'm developing an application that will be available from a website (market probably as well). The problem I'm having at the moment is how to handle the updates to the app. I know how to check the version against the current one and I know if I need to update it. Question is...how?

Is there a way I can download an APK from the website and start the install process? The user will have to confirm of course, but I just want to be able to start it for him. At the moment I'm doing this:

private void doUpgrade() {

// TODO Auto-generated method stub Builder builder = new AlertDialog.Builder(this); builder.setTitle(getString(R.string.upgrade)); builder.setIcon(R.drawable.help); builder.setMessage(getString(R.string.needUpgrade)); builder.setPositiveButton(getString(R.string.ok), new DialogInterface.OnClickListener() {

@Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub

Map<String, String> data = new HashMap<String, String>();

   try {
    HttpResponse re = Registration.doPost("http://www.android-town.com/appRelease/AndroidTown.apk",data);

    int statusCode = re.getStatusLine().getStatusCode();
    closeApp();

   } catch (ClientProtocolException e) {
             e.printStackTrace();
             Toast.makeText(getApplicationContext(), getString(R.string.noURLAccess), Toast.LENGTH_SHORT).show();
             closeApp();
   } catch (IOException e) {
             e.printStackTrace();
             Toast.makeText(getApplicationContext(), getString(R.string.noURLAccess), Toast.LENGTH_SHORT).show();
             closeApp();
   }

} }); builder.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {

@Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub dialog.cancel(); closeApp(); } }); builder.show(); }

But it doesn't really do anything...should I open a webView with the URL? A new runnable thread? Any other way? Please help :)

Cheers
