    <p>I have a main class "A". That calls a method in class "B". In class A I pass the parameter getAplicationContext() to the method in B.</p> <p>That method in "B" class is where <code>tempContext</code> is a Context object (Global):</p> <pre><code> public void backit(Context con) throws Exception { tempContext = con; Completion perThread; perThread = new Completion(); perThread.start(); } </code></pre> <p>The Completion Class is:</p> <pre><code>public class Completion extends Thread { ProgressDialog progDialog; int maxvalue; public void run() { maxvalue = BackupOperation.con_num; progDialog = new ProgressDialog(tempContext); Log.d("TEST", "HELLO"); } } </code></pre> <p>My application force closes. With exceptions:</p> <pre><code>12-04 22:41:28.984: W/dalvikvm(19517): threadid=10: thread exiting with uncaught exception (group=0x40af3228) 12-04 22:41:29.104: E/AndroidRuntime(19517): FATAL EXCEPTION: Thread-15840 12-04 22:41:29.104: E/AndroidRuntime(19517): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 12-04 22:41:29.104: E/AndroidRuntime(19517): at android.os.Handler.&lt;init&gt;(Handler.java:121) 12-04 22:41:29.104: E/AndroidRuntime(19517): at android.app.Dialog.&lt;init&gt;(Dialog.java:127) 12-04 22:41:29.104: E/AndroidRuntime(19517): at android.app.AlertDialog.&lt;init&gt;(AlertDialog.java:114) 12-04 22:41:29.104: E/AndroidRuntime(19517): at android.app.AlertDialog.&lt;init&gt;(AlertDialog.java:98) 12-04 22:41:29.104: E/AndroidRuntime(19517): at android.app.ProgressDialog.&lt;init&gt;(ProgressDialog.java:77) </code></pre> <p>I can figure out that <code>tempContext</code> when i refer it in the thread, my application force closes.

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.
