Design principle and implementation process of pattern unlocking in AndroidIn Android, to unlock a pattern, you must first understand the implementation principle of the pattern. The previous figure shows that the gesture records in the pattern are 1-9 or 0-8, and the password is saved in the order, of course, some of them can be repeated. For the sake of security, the original sequence cannot be stored dir

We described the broadcast mechanism of the Android system, in essence, it is a message subscription/advertisement mechanism, so the first step to use such a message-driven model is to subscribe to the message, and for Android applications, the subscription message is actually a register broadcast receiver, This article explores how the Android app will register

In Android, each application is made up of activity and service that are likely to run in the same process or run in different processes. So how do you communicate with an activity or service that is not in the same process? This is the binder interprocess communication mechanism to be introduced in this article. We know that the
