    <p>For the first problem (chooser issue), the reason you are getting the error "no application can perform this action" is because the <code>Intent</code> you are passing to <code>getChooser()</code> doesn't have an ACTION in it that Android can use to search for applications that can handle the <code>Intent</code>. <code>getChooser</code> will use the ACTION, CATEGORY and DATA in the <code>Intent</code> to search for suitable applications. It will then use package and component names to filter this list. In your case, because you've only provided the package and component names (but haven't specified ACTION), Android can't find any suitable applications. I'm not sure there's a way around this, since you want to build a list with different packages. You may just need to create your own chooser dialog (which is probably the correct thing to do here anyway, as you don't really get any advantages using the Android chooser because you've already decided what the list should contain).</p> <hr> <p>For the second problem (if application is in background, it gets restarted) you need to use the following flags:</p> <pre><code>targetedIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); </code></pre> <p>Specifying <code>Intent.FLAG_ACTIVITY_NEW_TASK</code> when launching the root activity of a task will bring an already existing task to the foreground.</p> <p>NOTE: If you want to just bring the existing task to the foreground (in whatever state it happens to be), then just use <code>Intent.FLAG_ACTIVITY_NEW_TASK</code> and remove the other 2 flags.</p>

    1. COThe solution for the second for the second problem works ok. I have a question about building my own dialog for the chooser (I figured that was the only resonable solution here): how would I go about that, since the chooser is launched from the pendingIntent ? (I cannot just launch a dialog from nowhere)

    2. COFrom your notification you can launch an activity that looks like a dialog. Search StackOverflow and you will find examples.

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.
