Question

Trying to show ProgressDialog, but getting:
Can’t create handler inside thread that has not called Looper.prepare().

Here is my code:

    public class SocketThread implements Runnable {
    BufferedReader in;
    private ProgressDialog dialog;

    public void run() 
    {
        socket = null;

        while (true)
        {
            // Loop until connected to server
            while (socket == null){
                dialog = new ProgressDialog(getApplicationContext());
                dialog.setMessage("Connecting to " + gatewayString);
                dialog.setIndeterminate(true);
                dialog.setCancelable(true);
                AdvancedMultipleSeriesGraph.this.runOnUiThread(new Runnable() {     
                    public void run() {
                        dialog.show();

                    }
                });

Is it possible to fix?

Answer 1

you can use an Handler and use Handler.post(Runnable) or, if you have an activity context you can use Activity.runOnUiThread(Runnable action)
