java.lang.SecurityException: Permission Denial in android

[rashmi swamy]

Hi,
I am trying to disable the application by using following code in android

PackageManager pm = this.getPackageManager();
pm.setComponentEnabledSetting(new ComponentName("com.sasken.remotesample",".Player"),
PackageManager.COMPONENT_ENABLED_STATE_DEFAULT, PackageManager.DONT_KILL_APP);

and with permission in Androimanifest.xml is
<uses-permission android:name="android.permission.CHANGE_COMPONENT_ENABLED_STATE"/>

But it is giving me the exception

java.lang.SecurityException: Permission Denial: attempt to change component state

Please give me the solution
