    <p>I am using a <code>contentObserver</code> to monitor the content of the <code>sms content provider</code>, I have put a <code>Log.d()</code> tag for debugging and the tag in the <code>logcat</code> is being seen more than once meaning the <code>onchange()</code> id being called more than once, how do I prevent this from happening. I have implemented the observer in a service running in the background. Here is the code</p> <pre><code>package com.messageHider; import android.app.Service; import android.content.ContentResolver; import android.content.Intent; import android.database.ContentObserver; import android.database.Cursor; import android.net.Uri; import android.os.Handler; import android.os.IBinder; import android.util.Log; import android.widget.Toast; public class smsSentService extends Service { ContentResolver contentResolver; Uri uri=Uri.parse("content://sms/"); Handler handler; @Override public IBinder onBind(Intent arg0) { return null; } @Override public void onCreate() { contentResolver=getContentResolver(); contentResolver.registerContentObserver(uri, true, new contentObserver(handler)); Log.d("SENTSERVICE", "Service created"); super.onCreate(); } @Override public void onStart(Intent intent, int startId) { Log.d("SENTSERVICE", "Service started"); super.onStart(intent, startId); } @Override public void onDestroy() { super.onDestroy(); } public class contentObserver extends ContentObserver { public contentObserver(Handler handler) { super(handler); } @Override public void onChange(boolean selfChange) { Cursor cursor=contentResolver.query(uri, null, null, null, null); cursor.moveToFirst(); String type=cursor.getString(cursor.getColumnIndex("type")); Log.d("THEMESSAGE", type); super.onChange(selfChange); } } </code></pre> <p>}</p> <hr>

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.
