I know that i start a new asynctask but it is the only way to auto clear the memories both lru and disk when the user exits the activity. first of all i use this (bad) technic because i don't want to waste the user's space with useless things for him and without let him know how much space do i need. Second in my application the user can navigate to this activity from the home activity using different image resources every time, so after a long time there will be a very big amount of things on the application's cache folder. how can i achieve to clear the cache folder every time the user leaves the activity without using this technic? also is this responsible for the problem i mentioned before? i am asking this because when i use only the wifi the problem never occurs no matter how many times the user will relaunch the activity.
