This article is mainly about: using the camera API to capture video data and save to a file, using Surfaceview, Textureview to preview the Camera data, take the NV21 data callback.Note: Requires permission:First, preview the Camera dataPeople who have done Android development generally know that there are two ways to d

This article translated from: http://developer.android.com/training/camera/videobasics.html This article describes how to use the existing Camera application to take videos. If your application only needs to integrate a small part of the video function, you can use the camera application provided on most Android device

one, what can Android camera do? 1. function Take photos Video recording Viewfinder (scanning applications such as face recognition, business card recognition, barcode recognition) 2, according to the camera API to achieve their own photo program, a total of 7 steps Created with Rapha?l 2.1.2

In the previous chapter, we completed the configuration of the Android Platform development environment, and also found a way to remove the OpenCV Manager API, then we start from scratch, the completion of a personal program, the implementation of the following functions:1. Identify the specified picture and draw the edge of the picture with a colored box2. Display a 3D model on the identified imageIt is not difficult to see that this is actually the

) { super.handlemessage (msg); SYSTEM.OUT.PRINTLN ("Update ..."); } } 2. Create a new thread class that implements the Runnable interface, using a Boolean to control thread start and end Boolean islive = True as follows:[Java]View Plaincopy Public class MyThread implements Runnable { @Override public Void Run () { While (islive) { try { Thread.Sleep (+); Thread paused for 1 seconds, per millisecond Message message = new Message (); Message.what = 1;

Because the timer and the TimerTask class object can only be used once, if you want to dispatch the same task multiple times, you must instantiate it again.So, a Timerhelper class is encapsulated, and the test is available.1 Public Abstract classTimerhelper {2 3Private Timer Mtimer =NULL;4 5 Public voidStartLongDelayLongperiod)6 {7 stop ();8 9Mtimer =NewTimer ();TenMtimer.schedule (NewTimerTask ()

The time-Dispatch module was used in the recent project development, and Quartz.net was used in. NET development, and then downloaded the Java Quartz module, but it appeared in use java.lang.NoClassDefFoundError Anomalies, and later on-line search found alternative methodsUsing the system comes with the timer code as follows: Public class extends timertask{ @Override publicvoid run () { System.out.println ( New Date ());} }SimpleDateF

Place a timer with the specified detail date and time1 Public classMainactivity extends Activity {2 3 PrivateHandler Handler =NewHandler () {4 @Override5 Public voidhandlemessage (Message msg) {6 Switch(msg.what) {7 Case 1:8LOG.I ("====","performed a");9 //the code that needs to be executed is put hereTen Break; One } A } - }; - the @Override -

Now that this class has been discovered, let's share it:The remaining time is constantly shown in a TextView code as follows:[Java]View Plaincopy Private TextView Vertifyview; private Countdowntimer

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

These days I took part in a company-run programming marathon, and I intend to use the Android camera to do it. I've always thought that the Android API was bad, but it didn't say exactly what was bad or how it would be better to improve. Take this opportunity and I'll explain it now. I think Android's API for webcam is awful, if you haven't used it, take a moment

Let's play the video function of the mobile phone. Do a demo. look at the recording process： Copy Code code as follows: Mediarecorder = new Mediarecorder ();//Create Mediarecorder Object Set the recording video source to camera (camera) Mediarecorder.setvideosource (MediaRecorder.VideoSource.CAMERA); Set the package format for the video after the recording is complete THREE_GPP to 3gp.mpeg_

The calling process of camera in android can be divided into the following layers:Package-> framework-> JNI-> camera (CPP) -- (binder) --> cameraservice-> camera Hal-> camera driver Take the photo taking process as an example:1. After each parameter is set, after focusing is

One in Android, the ACTION that corresponds to the photo is Android.provider.MediaStore.ACTION_IMAGE_CAPTURE. The activity used for taking pictures needs to return the photo image data,The ACTION that corresponds to the camera is Android.provider.MediaStore.ACTION_VIDEO_CAPTURETherefore, you need to use Startactivityforresult () to start the Activity. The code is as follows:Intent Intent = new Intent (media

This example describes the use of Countdowntimer countdown in Android. Share to everyone for your reference, specific as follows: In peacetime we are programmed, often use the countdown to this function, many people do not know that Android has helped encapsulate a class, often write their own. Now that this class has been found, we share it: In a TextView continuously display the remaining time, the code
