    copied!<p>I have created a ProgressDialog in android and it works when I do a simple example. </p> <p>For example, this works.</p> <pre><code>public void onClick(View v) { // Perform action on click System.out.println("Progess Bar"); final ProgressDialog myProgressDialog = ProgressDialog.show(AndroidTestApplicationActivity.this, "Please wait...", "Getting updates...", true); new Thread() { public void run() { try { // Do some Fake-Work sleep(5000); } catch (Exception e) { } // Dismiss the Dialog myProgressDialog.dismiss(); } }.start(); } </code></pre> <p>But once I add in a reference to my custom class, it just stops running this new thread. </p> <pre><code> button1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // Perform action on click System.out.println("Progess Bar"); // Display an indeterminate Progress-Dialog final ProgressDialog myProgressDialog = ProgressDialog.show(AndroidTestApplicationActivity.this, "Please wait...", "Getting Updates...", true); new Thread() { public void run() { try { HealthySubObject hsObject = new HealthySubObject(); // Do some more work with my hsObject - nothing happens after this point. sleep(5000); } catch (Exception e) { } // Dismiss the Dialog myProgressDialog.dismiss(); } }.start(); } }); </code></pre> <p>What happens is that as soon as I click this button, the progress dialog flashes up on the screen real quick and then disappears. But if you look at my code, it should wait 5 seconds before disappearing. I have put debug statements before and after the reference to my custom class and I can see the statements before but not the ones after. Does anyone have any idea why that is happening? As long as my class is public I should be able to call it from a new thread, right? </p> <p>I am still pretty new to android and this is my first adventure into multi-threaded android apps. Any help would be much appreciated. </p> <p><em><strong>SOLUTION</em></strong></p> <p>Thanks for your help everyone. It is working now. </p> <pre><code> button1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // Perform action on click System.out.println("Progess Bar"); //ProgressDialog dialog = ProgressDialog.show(AndroidTestApplicationActivity.this, "", "Loading. Please wait...", true); // Display an indeterminate Progress-Dialog final ProgressDialog myProgressDialog = ProgressDialog.show(AndroidTestApplicationActivity.this, "Please wait...", "Doing Extreme Calculations...", true); Handler handler = new Handler(); handler.postDelayed(new Runnable() { @Override public void run() { HealthySubObject hsObject = new HealthySubObject(); ArrayList&lt;HashMap&lt;String, String&gt;&gt; onlineDB = hsObject.jsonToArray(); // // more stuff goes here. // // myProgressDialog.dismiss(); } }, 1500); } }); </code></pre>
