Initialize
EZCam cam = new EZCam(Context);
String id = cam.getCamerasList().get(CameraCharacteristics.LENS_FACING_BACK); // should check if LENS_FACING_BACK exist before calling get()
cam.selectCamera(id);
Callback
cam.setCameraCallback(new EZCamCallback() {
@Override
public void onCameraReady() {
// triggered after cam.open(...)
// you can set capture settings for example:
cam.setCaptureSetting(CaptureRequest.COLOR_CORRECTION_ABERRATION_MODE, CameraMetadata.COLOR_CORRECTION_ABERRATION_MODE_HIGH_QUALITY);
cam.setCaptureSetting(CaptureRequest.CONTROL_EFFECT_MODE, CameraMetadata.CONTROL_EFFECT_MODE_NEGATIVE);
// then start the preview
cam.startPreview();
}
@Override
public void onPicture(Image image) {
File file = new File(getFilesDir(), "image.jpg"); // internal storage
File file = new File(getExternalFilesDir(null), "image.jpg") // external storage, need permissions
EZCam.saveImage(image, file);
}
@Override
public void onError(String message) {
// all errors will be passed through this methods
}
@Override
public void onCameraDisconnected() {
// camera disconnected
}
});
Open Camera
cam.open(CameraDevice.TEMPLATE_PREVIEW, textureView); // needs Manifest.permission.CAMERA
Take picture
cam.takePicture();
Close camera
@Override
protected void onDestroy() {
cam.close();
super.onDestroy();
}
