PhotoCropper is a light-weight but sharp and smart tool to help you cropping photos on android devices. By providing a simple callback interface for developers and encapsulating the tricky things of cropping photos into a library. It makes the logic much more easier and simpler.

If you want to learn more details about this, my blogs might help you.

## Usage

It's really easy to use, but always remember:

### IMPORTANT NOTICE!

**Always clear your cached cropped images from last time.**

```java

// MUST!! Clear Last Cached Image

CropHelper.clearCachedCropFile(mCropParams.uri);

startActivityForResult(CropHelper.buildCropFromGalleryIntent(mCropParams), CropHelper.REQUEST_CROP);

```

### Step 1

First you need a ``CropHandler`` to handle the activity results of cropping photos.

```java

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);

    CropHelper.handleResult(cropHandler, requestCode, resultCode, data);

}

```

### Step 2

Make sure you implemented these methods:

```java

@Override

public void onPhotoCropped(Uri uri) {

    // The cropped result

    // uri relates to the cropped photo

    // ...

}

@Override

public Activity getContext() {

    // MUST NOT be null

    return mContext;

}

@Override

public CropParams getCropParams() {

    // Your own crop options, simply call new CropParams() will give you a set of default crop options 

    mCropParams = new CropParams();

    return mCropParams;

}

@Override

public void onCropFailed(String message) {

    // ...

}

@Override

public void onCropCancel() {

    // ...

}

```

### Step 3

Launch a request to crop photos.

#### Crop from camera

```java

Intent intent = CropHelper.buildCaptureIntent(mCropParams.uri);

startActivityForResult(intent, CropHelper.REQUEST_CAMERA);

```

#### Crop from gallery

```java

Intent intent = CropHelper.buildCropFromGalleryIntent(mCropParams);

startActivityForResult(intent, CropHelper.REQUEST_CROP);

```

### Step 4

Clear the cached image if possible.

```java

@Override

protected void onDestroy() {

    if (cropHandler.getCropParams() != null)

        CropHelper.clearCachedCropFile(cropHandler.getCropParams().uri);

    super.onDestroy();

}

```

## Dependency Support

### Gradle

```

compile 'org.hybridsquad.android.photocropper:library:2.1.0'

```
