Write an Android application

There are 3 activities. A) MainActivity. This is a home page B) CameraActivity. This launches a camera and shows a preview of what it sees. It uses a CameraPreview class. It also launches a 3 second countdown at the end of which the photo is taken. C) ImageActivity. This is launched when the photo is taken and shows the recently captured image. Then there are icons where the photo can be shared on social media or downloaded. Now, the issues that need to be fixed are as follows: 1. There can be no skipped frames. Right now when this app is ran in log cat (android-studio), you can see it skips frames when activity B starts and also at the end of activity B. You need to change whatever is causing this so that there are no skipped frames anywhere. This may involve separating the saving of the image onto a separate thread from the one that launches activity C. 2. The aspect ratio needs to be consistent. Right now there is stretching of the image in different directions. Additionally the captured image is rotated to landscape mode. You need to fix this. The image should never be in landscape mode, only portrait mode. The image should maintain the same aspect ratio and full resolution and appearance during the camera preview, on the picture that is saved or shared to social media, and on the Image Preview that shows the captured image. The image should always fill the full width of the screen. If it needs to be shortened (with space above or below the image) in order to maintain the aspect ratio, that is OK. 3. Crashing. Right now Activity B causes most, but not all android phones to crash. From what I have seen (on a galaxy s4 active, but not tested on other phones), this is due to a java.lang.outOfMemoryError. However, I am not sure that this is the cause, so you may need to find out the real issue yourself. I think this could be addressed with the same fix as is needed on part 1 (separating the threads), but Im not sure. This app needs to work on all android phones down to sdk 10.
