and the menifest is

   <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.pref"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />
    <uses-permission android:name="android.permission.INTERNET"/>

<uses-permission android:name="android.permission.BACKUP" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" 
         android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
         android:backupAgent="com.pref.BackupManagerExample">
         <activity android:name=".Preff" />



        <activity
            android:name=".PrefrencesActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>
        </activity>


         <meta-data android:name="com.google.android.backup.api_key"
    android:value="AEdPqrEAAAAIo8gaMLEy1sb1bVd6Cyqs5dxPAy8qvFzfILeLWB" />
         <activity
            android:name=".BackupManagerExample"
            android:enabled="true"/>

    </application>

</manifest>

Ther Error is here

 Resotre.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                try {
                    // TODO Auto-generated method stub

// This line shows the error

 mBackupManager.requestRestore(
                                    new RestoreObserver() {
                                        public void restoreFinished(int error) {
                                            Log.v(TAG, "Restore finished, error = " + error);
                                            populateUI();
                                        }
                                    }
                            );
                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            });

What could be the cause for this error ? And how can i remove it ?

Edit

Not olny this but i also used this code ,

https://github.com/StylingAndroid/BackupRestore

Just to see how backup API works and this also gave the same error .

07-31 18:10:33.226: E/AndroidRuntime(20664): Caused by: java.lang.SecurityException: getCurrentTransport: Neither user 10072 nor current process has android.permission.BACKUP.

From here i read

http://developer.android.com/guide/topics/data/backup.html

Data backup is not guaranteed to be available on all Android-powered devices. However, your application is not adversely affected in the event that a device does not provide a backup transport.

The device i am using is a samsung galaxy pop.

have you registered your app at https://developers.google.com/android/backup/signup — nandeesh, Jul 31 '12 at 08:27

You are trying to use the BackupManager directly and you cannot do that without the android.permission.BACKUP permission. That permission is only granted to apps signed with the platform key (basically system apps).

You are requesting the permission in your manifest but if you watch the logs while you install you should see the "Not granting permission" warning for your app.

So in the end your code looks generally correct but you are just getting a security exception when trying to call the protected methods.
