Solve an error on hidden camera app

Here I am listing all issues and requirements: Requirements : REMEMBER, Below 5 functionalities are done already. You just have to create 5 buttons and start each service when corresponding button clicked. We need an app with 1 screen (here functionality most important) with following functions : 1) Back camera picture taking WITHOUT FLASH 2) Back camera picture taking WITH FLASH 3) Front camera picture taking 4) Back cam video recording 5) Front cam video recording ALL THESE TO BE DONE IN BACKGROUND SERVICE AND NOT ACTIVTY CODE So whenevr i click a button , the corresponding service should be started immediately and, image should be taken, and, another readymade service to be called to upload file created and service should end when image taken and file saved. PLEASE REMEMEBER , ALL THESE ARE DONE ALREADY. YOU JUST HAVE TO MAKE 5 buttons and repair existing services for the above 5 features. ISSUES arising: 1. CamerService (one responsible for hanging device sometimes/ or not capturing image /not capturing image immediately) , needs to be fixed Device gets frozen and stays like that until image taken. This becomes an issue when image not taken immediately and hence device stays frozen for minutes. 2. BackgroundVideoRecorder (for videos) - Please chek it once, If it runs well , then good else fix. 3. Front cam VIDEORECORD Not implemented yet. You please modify Backgroundvideorecord to make it record front camera also. Or u may make a new file. I am attaching another file named ServiceCalls which tell you how this service calls are being made. Quotation not acceptable 10USD as this is MODIFICATION based only. If we like your work we may work with you in future also.
