I would like to generate an efficient image compression technique that should satisfy any of image quality metrics for smart phones..how to incorporate it with android ?

MATLAB Mobile does not run code on the Android. MATLAB Mobile provides a graphics interface to MATLAB that is being run elsewhere. MATLAB Mobile is not intended for use by an application on the Android to send commands to a remote MATLAB engine and get back results.
MATLAB Coder would be appropriate for converting MATLAB code to be compiled for Android. Note that MATLAB Coder does not know anything about Android specifically, and would just treat it as any other non-graphics C or C++ system. Also there are quite a number of things that cannot be compiled with MATLAB Coder; see https://www.mathworks.com/help/simulink/ug/functions-supported-for-code-generation--categorical-list.html
On the other hand, if you can put together the structure using Simulink, then Simulink knows how to deploy to Android, and can make use of Android facilities that MATLAB itself does not know about.
"Any of the image quality metrics such as MSE,PSNR,Compression Ratio"
Those are not metrics, those are measurements. A MSE of 4230089.394 might be for an image that is perfectly satisfactory for its purpose. For there to be a metric, you have to have a limit, such as "PSNR must be greater than 4230089.394" or "Compression Ratio for selfies taken at 3.14159 metres with a brightness of 18000 lumens of Sodium-Argon lamps run at 217 volts of three phase current, and for which the white point is D65, must be at least 4230089.394 to 1".
