Features
- Image and video capture seamlessly working with the same preview session.
- Automatic system permission handling.
- Automatic preview scaling.
- Create a
CameraViewof any size (not just presets!). - Automatic output cropping to match your
CameraViewbounds.
- Create a
- Multiple capture modes.
PICTURE_MODE_QUALITY: an image captured normally using the camera APIs.PICTURE_MODE_SPEED: a freeze frame of theCameraViewpreview (similar to SnapChat and Instagram) for devices with slower cameras.- Automatic picture mode determination based on measured speed.
Setup
Add CameraKit to the dependencies block in your app level build.gradle:
compile 'com.flurgle:camerakit:1.0.0'
Usage
To use CameraKit, simply add a CameraView to your layout:
<com.flurgle.camerakit.CameraView
android:id="@+id/camera"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Make sure you override onResume and onPause in your activity, and make calls respectively to CameraView.start() and CameraView.stop().
@Override
protected void onResume() {
super.onResume();
cameraView.start();
}
@Override
protected void onPause() {
cameraView.stop();
super.onPause();
}
Events
Make sure you can react to different camera events by setting up a CameraListener instance.
camera.setCameraListener(new CameraListener() {
@Override
public void onCameraOpened() {
super.onCameraOpened();
}
@Override
public void onCameraClosed() {
super.onCameraClosed();
}
@Override
public void onPictureTaken(byte[] picture) {
super.onPictureTaken(picture);
}
@Override
public void onVideoTaken(File video) {
super.onVideoTaken(video);
}
});
Extra Attributes
<com.flurgle.camerakit.CameraView xmlns:camerakit="http://schemas.android.com/apk/res-auto"
android:id="@+id/camera"
android:layout_width="match_parent"
android:layout_height="match_parent"
camerakit:ckCropOutput="true"
camerakit:ckFacing="back"
camerakit:ckFlash="off"
camerakit:ckPictureMode="quality" />
ckCropOutput
| Value | Description |
|---|---|
true |
Crop the output image or video to only contain what can be seen on the CameraView preview. |
false |
Output the full image or video regardless of what is visible on the CameraView preview. |
ckFacing
| Value | Description |
|---|---|
back |
Default CameraView preview to back camera. |
front |
Default CameraView preview to front camera. |
ckFlash
| Value | Description |
|---|---|
off |
Default CameraView flash to off. |
on |
Default CameraView flash to on. |
auto |
Default CameraView flash to automatic. |
ckPictureMode
| Value | Description |
|---|---|
quality |
Use normal Android Camera API image capturing. |
speed |
Freeze the CameraView preview and grab a Bitmap of the frame. |
auto |
Default picture mode to quality, but fallback to speed if capturing is determined to be too slow. |
Capturing Images
To capture an image just call CameraView.capturePicture(). Make sure you setup a CameraListener to handle the image callback.
camera.setCameraListener(new CameraListener() {
@Override
public void onPictureTaken(byte[] picture) {
super.onPictureTaken(picture);
// Create a bitmap
Bitmap result = BitmapFactory.decodeByteArray(picture, 0, picture.length);
}
});
camera.takePicture();
Capturing Video
To capture video just call CameraView.startRecordingVideo() to start, and CameraView.stopRecordingVideo() to finish. Make sure you setup a CameraListener to handle the video callback.
camera.setCameraListener(new CameraListener() {
@Override
public void onVideoTaken(File video) {
super.onVideoTaken(video);
// The File parameter is an MP4 file.
}
});
camera.startRecordingVideo();
camera.postDelayed(new Runnable() {
@Override
public void run() {
camera.stopRecordingVideo();
}
}, 2500);
Automatic Permissions Behavior
You can handle permissions yourself in whatever way you want, but if you make a call to CameraView.start() without the android.permission.CAMERA permission, an exception would normally be thrown and your app would crash.
With CameraKit, we will automatically prompt for the android.permission.CAMERA permission if it's not available. If you want to handle it yourself, just make sure you dont call CameraView.start() until you acquire the permissions.
