    <p>I've got an Activity like this:</p> <pre><code>public class StudentActivity extends Activity { static final int DIALOG_PROGRESS = 0; public void btnSyncStudentsClick(View view) { syncStudents(); } @Override protected Dialog onCreateDialog(int id) { Dialog d = null; switch (id) { case DIALOG_PROGRESS: ProgressDialog dialog = new ProgressDialog(this); dialog.setMessage(getText(R.string.txt_refreshing_students)); d = dialog; break; return d; } private class RefreshStudentTask extends AsyncTask&lt;Void, Integer, AccountRefreshResult&gt; { @Override protected void onPreExecute() { showDialog(DIALOG_PROGRESS); } @Override protected AccountRefreshResult doInBackground(Void... params) { //some network requests } @Override protected void onPostExecute(AccountRefreshResult result) { dismissDialog(DIALOG_PROGRESS); //this throws an exception //some other stuff } } } </code></pre> <p>Since the dialog is shown in onPreExecute() and dismissed in onPostExecute(), I don't know why some of the users get an exception:</p> <pre><code>Uncaught exception handled :/ , thread: Thread[main,5,main] java.lang.IllegalArgumentException: no dialog with id 0 was ever shown via Activity#showDialog at android.app.Activity.missingDialog(Activity.java:2606) at android.app.Activity.dismissDialog(Activity.java:2591) at pl.mobireg.eparent.activities.StudentActivity$RefreshStudentTask.onPostExecute(StudentActivity.java:390) at pl.mobireg.eparent.activities.StudentActivity$RefreshStudentTask.onPostExecute(StudentActivity.java:364) at android.os.AsyncTask.finish(AsyncTask.java:417) at android.os.AsyncTask.access$300(AsyncTask.java:127) at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:429) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:130) at android.app.ActivityThread.main(ActivityThread.java:3691) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:507) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:912) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:670) at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>I cannot replicate this issue on my side, so it is very hard to debug.</p> <p>EDIT: Activity should only run in portrait mode:</p> <pre><code>android:screenOrientation="portrait" </code></pre>

Guidance
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.

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