Question

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

Easiest is just to launch an Intent to open the download URL in the Browser. This will download the APK and the user can then install it by clicking on it in the download manager.

You are saying that this will handle OTA separate to the market so the user should already have disabled “Allow apps from non-Market sources” when they initially installed your app.
