Learn more about art.While Google solves the problem of applying the total number of methods, it does not mean that developers can scale their projects arbitrarily. Multidex still have some limitations:Dex files are very complex to install to a device, and if the second Dex file is too large,

) The code involved in the JNI layer, because the JNI layer is written in C + +, you need to manage the allocation/recycling of memory, so be careful.So what is the effective way to detect memory usage and memory leaks in Android development?Here are three ways to focus:1.
