EZCam is an Android library that simplifies the use of Camera 2 API for a basic usage.

Dependencie

Add the following line in your gradle dependencies :

compile 'me.aflak.libraries:ezcam:X.X'

Or if you use Maven :

<dependency>
  <groupId>me.aflak.libraries</groupId>
  <artifactId>ezcam</artifactId>
  <version>X.X</version>
  <type>pom</type>
</dependency>

TextureView

Important : The TextureView must be in a FrameLayout.

<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextureView
    android:id="@+id/textureView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>
</FrameLayout>

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();
}
