您不能以任何方式从其他线程（不是 UI 线程）修改 UI。因此，在 AsyncTask.doInBackground 方法中创建/显示/关闭对话框是非法的，并且您遇到了崩溃。

Don't do like this on doInBackground, it's not a UI thread.

loginDialog = new AlertDialog.Builder(Login.this).create();
loginDialog.setTitle("Login Alert!");
loginDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "Back", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        // TODO Auto-generated method stub
        loginDialog.dismiss();
    }
});

You may return the action as string, which is why you have this:

protected String doInBackground(String... params)

pass and evaluate it in onPostExcecute() if you want to dismiss dialog (if you're not evaluating anything after the job done, just put a Void instead of String). If you want to create dialog, do it on onPreExecute(). They both run on UI thread.

For example:

@Override
protected void onPreExecute() {
super.onPreExecute();
    progressDialog = new ProgressDialog(context);
    progressDialog.setCancelable(false);
    progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    progressDialog.setMessage("Sending message....");
    progressDialog.show();
}
