Hi Tikoze, You can very easily implement this feature. Just have a simple receiver to receive the same intent as the camera that is:
android.intent.action.CAMERA_BUTTON In that receiver class start your required activity as required. And, in the corresponding AndroidManifest.xml of your application declare the receiver as below: < receiver android:name=*".TestReceiver"*> <intent-filter android:priority=*"10000"*> <action android:name=*"android.intent.action.CAMERA_BUTTON" */> </intent-filter> </receiver> The priority field tells Android to first choose the activity with the higher priority. I have used a very large value. Maybe even a smaller value will work. Also, in your receiver in the first line of your onReceive itself add the following line: abortBroadcast(); This will set a flag to abort the broadcast so nobody else will receive it after you. So, by setting the priority you are telling Android to choose your receiver first and by abortBroadcast you are cancelling the broadcast for Camera so it wont open at all. Hope this helps. Thanks and Regards, Pradeep Kaushik Thanks and Regards Pradeep.N.Kaushik.
