If the system cannot get enough RAM by recycling, then he empties all the LRU caches and starts to kill the processes that they want to keep, such as owning a process that is running a background service.Similarly, when your app

request more memory, there will be OutOfMemory an error.In some special scenarios, you can declare a larger heap space by adding attributes under the Application tab of the manifest largeHeap=true . If you do this, you can get to a larger heap size by Getlargememoryclass ()).However, the ability to get a larger heap is designed for a small number of applications that consume a lot of RAM (such as an editing application for a large picture). don't be so easy because you need to use a lot of memo
