Issue with the release of Google Glass

Question

I am developing glassware that shows you cards (images + text) from a list. To see all the Cards one by one, you just need to move your head and get information. An application is an application that looks like What around glassware .

I implemented SensorManager to get the current user orientation, and based on this current direction, the application decides which map to show.

here all the images come from the web server, so every time a card is selected, there is a network call for images (bitmap caching is performed) .

Now, what is my problem, when I launch and use the application, the glass quickly heats up in less than 1 minute.

Can anyone suggest me something to fix this problem.

Note: google glass os version: XE22
