An Optimization of Memory Usage Based on the Android Low Memory Management Mechanisms

When users manipulate low memory Android devices, they frequently encounter the application problem of loading slowly because of limited amount of memory. In particular, more applications installed, problems will occur more frequently. We deeply observe the low memory management mechanism of the Android system and find the system has some shortcomings, such as memory recovery efficiency, unnecessary memory requests. In this paper, we optimize memory usage by improving recovery efficiency, prioritize the use of less memory, prevent the instantaneous increase in memory usage, and reduce unnecessary memory requests. Experimental results in a real environment show that our methods effectively increase the size of free memory, and reduce the phenomenon of application self-startup and association startup.
