Android strength pointer analysis and testing

I haven't updated my blog for a long time. I was too lazy some time ago. After the new year, only one article unrelated to technology was updated from home to work. In the next few days, I hope I can write more blogs, and appropriately add some anecdotes in the technical blog (for example, the life and death of the fat man Jin San next door after surgery these days), and add some technical things in the life blog to increase the readability and interest of the blog. Let dear readers learn knowledge in happiness
