Showing Dialog after another Dialog: HANGS

I have a really weird problem, which I am unable to debug so far... Thing is...my app needs to download something to work. So in the beginning of the onCreate() method, I check if that something is already downloaded. If not, I pop a dialog up asking the user to download it.

if (!isInstalled) {
            showDialog(DIALOG_INSTALL);
        } else {
            start();
        }

Where start() method performs some other action. Now, that showDialog calls this:

builder = new AlertDialog.Builder(MyApp.this);
        builder.setMessage("Would you like to install...")
        .setCancelable(false)
        .setPositiveButton("Install", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                dialog.dismiss();
                aManager.install(MyApp.this);
            }
        });
        dialog = builder.create();
        return dialog;

My dialog is shown and I am clicking, so aManager.install() is called. I am passing the context because that aManager.install() pops up a ProgressDialog to show downloading progress and spawns a new thread in which everything is downloaded. So obviously before creating my dialog I make a Handler to receive the response from that aManager.install(). And the response MAY vary, because for example the internet connection isn't available (Exception raised and catched and listener called with differe开发者_如何学Cnt code).

Now, when that happens (Exception) I would like to call another dialog saying "something went wrong, would you like to retry?"...so another call to showDialog(DIALOG_REINSTALL) (this time with another code). Thing is...the showDialog() gets called (I can verify this by logging) but the dialogs doesn't show up. Instead my application JUST HANGS!?!?!?

Does someone have a clue why it's doing this???? No exception raised, absolutely nothing from logcat, I can't tell WHERE it's hanging...just see that the method is called and the dialog should be displayed...

Thank you very much!!

Looks like you have a deadlock. I would put the download code on the separate thread e.g. use AsyncTask. In task.onPreExecute() you can dismiss 1st dialog and pop-up your progress dialog which you update by overwriting task.onProgressUpdate()

Use .show() instead of .create().
