    <p>I have a working implementation of C2DM, if I handle each message I receive with a Toast.</p> <p>Instead, I would like to use an Alert Dialog, which the user says OK to so as to acknowledge the message.</p> <p>The code I've written for this generates an exception at the show() line. I expect the issue may be to do with the context used (?).</p> <pre><code>AlertDialog.Builder alertbox = new AlertDialog.Builder(context); alertbox.setMessage("Received Push Notification"); alertbox.setNeutralButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface arg0, int arg1) { // TODO Auto-generated method stub } }); AlertDialog alert = alertbox.create(); alert.show(); </code></pre> <p>Full Class (as requested in comment):</p> <pre><code>public class MyC2DM extends BroadcastReceiver { public MyC2DM() { } @Override public void onReceive(Context context, Intent intent) { Log.i("Recieve","2"); //Toast.makeText(context, "Intent Receive!", Toast.LENGTH_SHORT).show(); if (intent.getAction().equals("com.google.android.c2dm.intent.REGISTRATION")) { handleRegistration(context, intent); } else if (intent.getAction().equals("com.google.android.c2dm.intent.RECEIVE")) { handleMessage(context, intent); } } private void handleRegistration(Context context, Intent intent) { String registration = intent.getStringExtra("registration_id"); if (intent.getStringExtra("error") != null) { Toast.makeText(context, "Reg Error!", Toast.LENGTH_LONG).show(); // Registration failed, should try again later. } else if (intent.getStringExtra("unregistered") != null) { // unregistration done, new messages from the authorized sender will be rejected Toast.makeText(context, "Unreg!", Toast.LENGTH_LONG).show(); } else if (registration != null) { // Send the registration ID to the 3rd party site that is sending the messages. // This should be done in a separate thread. // When done, remember that all registration is done. // UserId = customer.getId(); // Log.i("id",String.valueOf(UserId)); String RegId = registration; Log.i("reg",String.valueOf(RegId) ); } } private void handleMessage(Context context, Intent intent) { // Message handler.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
