Question

I\'m trying to open a dialog window, but every time I try to open it it throws this exception:

Uncaught handler: thread main exiting due to uncaught exceptio         


        

Answer 1

This Worked for me--

new AlertDialog.Builder(MainActivity.this)
        .setMessage(Html.fromHtml("Spread Knowledge Unto The Last"))
        .setCancelable(false)
        .setPositiveButton("Dismiss",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                    }
                }).show();

Use

ActivityName.this
