The Uri memeber variable gets set to null when onActivityResult gets called

so , the mMediaUri gets correctly set to the path in which the picture will be saved after it is taken , but after i take the picture and the device gets back in onActivityResult the mMediaUri variable is null and the app crashes . I think this is because when the camera starts the screen rotates for some reasons . I have read somewhere that on screen roatation the activity recreats . I think that is the point where the mMediaUri loses its value . How can I solve this ??

You should really post some code as well as the error. As for the screen orientation, a possible solution is to make the app stay in portrait mode only. Do do this, add the android:screenOrientation:="portrait" property to your manifest.

the only way I coul make it work was by using another app to take the photo , I downloaded the camera application from google and it worked fine . There's something with the camera app from the galaxy s4 that makes the app crash , when the camera app ends and the onActivityResult gets called the variables are reset , that doesn't happen with the camera app from google
