I have created a camera activity which will take pic from rear and front camera. But I am keep getting above mentioned error can any one help me out :
Seems like i am doing some mistake in Menifest file in calling intent but not able to figure it out what mistake i am doing.
Here is my CameraActivity.java

Your problem is here:
at com.qualcomm.post.core.multimedia.LaunchRearCameraTestAction.start(LaunchRearCameraTestAction.java:24)
In this code you need to add the new task flag to the Intent before calling startActivity() with:
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
