First of all, we found that most of the Android smartphones we use now have the power button to hang up when you're on the phone, usually in the setup. I mainly in the original source code to add this function, mainly for learning .... First look at a picture: See that press the power button to hang up the phone, that is what I added, originally source code is not this column ... probably thinking： First I add this checkboxpreference, and then I s

I recently contacted the Android platform JNI call and found that the network information has not provided a more detailed introduction from the principle to the specific implementation. Therefore, I have referenced some materials and added some experiences based on the project development: Origin of JNIJNI is the abbreviation of Java Native Interface. It allows Java code to interact with code written in ot

Application scenario: In the Android development process, it is sometimes necessary to call the phone's own device function, this article focuses on the camera function calls. Knowledge Points: Access to the phone's own device function (camera photo function), should ensure that the Androidmanifest.xml has been correctly stated in the use of the camera and other related feature 1. Camera Related permission

Intent redirects to the dial-up interface, contact interface, SMS interface, and other interfaces in the system application. Now, the functions under development need to jump directly to the dialing, contact, text message interface, and so on. After finding a lot of information, I sorted it out myself. First, let's look at the dialing interface first. The Code is as follows: Intent intent = new Intent (); Intent. setAction ("android. intent. action. C
