-AndroidUSBCamera 2.0
-============   
-  AndroidUSBCamera is developed based on the saki4510t/UVCCamera, the project of USB Camera (UVC equipment) and the use of video data acquisition are highly packaged, and it can help developers using USB Camera devices easily by a few simple APIs. By using AndroidUSBCamera,you can detect and connect to a USB Camera simply.And you also can use it to realize taking picture,recording mp4,switching resolutions and setting  camera's contrast or brightness,etc.Here is some gifs of this demo:

+(2) Capturing JPG Images  
+```java
+ mCameraHelper.capturePicture(picPath, new AbstractUVCCameraHandler.OnCaptureListener() {

+(3) Recording Mp4,supporting close voice and save file automatic.
+```java
+RecordParams params = new RecordParams();

+                    params.setRecordDuration(0);                        // 0,do not cut save

+                        public void onEncodeResult(byte[] data, int offset, int length, long timestamp, int type) {
+                            // type = 1,h264 video stream
+                            if (type == 1) {

+                            // type = 0,aac audio stream

+                        }
+                    });  
+```
+(4) setting camera's brightness and contrast.  
+```java
+mCameraHelper.setModelValue(UVCCameraHelper.MODE_BRIGHTNESS,progress);
+mCameraHelper.setModelValue(UVCCameraHelper.MODE_CONTRAST,progress);
+mCameraHelper.getModelValue(UVCCameraHelper.MODE_BRIGHTNESS);
+mCameraHelper.getModelValue(UVCCameraHelper.MODE_CONTRAST);
+...
+```
+(5) switch resolutions and camera.  
+```java
+mCameraHelper.updateResolution(widht, height);
+```
+At last,remember adding permissions:  
+```
+<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
+<uses-permission android:name="android.permission.RECORD_AUDIO" />
+```
