Preface
I recently wrote a mobile AR system from scratch. There are too many pitfalls !!! The entire project uses the OpenCV third-party library, but for cameras, the method is basically the same as that of native Camera.
Implementation
Taking JavaCameraView of OpenCV as an example, you must first customize your own Camera. The main code is as follows:
import java.util.ArrayList;import java.util.List;import org.opencv.android.JavaCameraView;import android.R.integer;import android.content.Conte
completion of the problem to solve (Ibid., Android Studio itself is not a problem, the habit of the problem), to show you the code of automatic completion of the shortcut key is the line, as to how you want to change how to change, this is your right.------------------------------------------------------------------------------Setup method:1. Click the file option in the upper left corner to find the settings2. After clicking Settings, find Keymap3.
The Eclipse for Android implementation code automatically prompts the smart prompt feature, introduced in the Eclipse for Android editor to implement the two main files Java and XML code automatic prompt function, to resolve the eclipse code hints invalid, eclipse cannot automatically mention There are no code hints for the eclipse. Eclipse XML Auto hint, Eclipse

are many ways to find permissions, and here is just one way to do it by Packagemnager:1.6 SummaryIn summary , the general self-priming management app in the market, mostly by the use of the PM command after root permission to disable the receiver containing the boot_completed, and others by monitoring the background process, polling to find the blacklist process to kill off the corresponding self-start program, not only the boot from the boot, but also to monitor the background self-booting, bu
resource files are defined in the R class under the Android package. The resource file format in the Access system is: Android. R. resource file type. resource file name. For example: java code: int i; //animation i = Android. r.anim.fade_in; //array i = Android. r.array.emailaddresstypes; //color i =
Monkeyrunner Tools Objective:Recently began to study the Android automated test method, some of the tools, methods and frameworks to do some simple collation, including Android test framework, CTS, Monkey, Monkeyrunner, benchmark, other test tool and so on. Because the contact time is very short, many places have the insufficiency, hoped can communicate with everybody.First, what is MonkeyrunnerThe Monkey

Compiling the Android operating system in the simulator can help us implement the auto-start function of the application at startup. Here, we will use a piece of code to fully master the implementation of Android boot auto-start, to help you master this application.

Textview vertical auto-scroll subtitle implementation
Some time ago, I found a post on the Internet, and textview automatically rolled the subtitles horizontally. Today's project needs to scroll the subtitles vertically. Its implementation principle is the same as that of water products. Both override the onDraw method of textview.Note the need to implement vertical auto-scroll subtitles1. You need to calcu

3. automatically count connection failures (more than 5 attempts to connect failed)
4. Connection failure + 1 o'clock vibration alert
