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.

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

Always clear your cached cropped images from last time.

// MUST!! Clear Last Cached Image
CropHelper.clearCachedCropFile(mCropParams.uri);

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

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

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    CropHelper.handleResult(cropHandler, requestCode, resultCode, data);
}

Make sure you implemented these methods:

@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() {
    // ...
}

Launch a request to crop photos.

Intent intent = CropHelper.buildCaptureIntent(mCropParams.uri);
startActivityForResult(intent, CropHelper.REQUEST_CAMERA);

Intent intent = CropHelper.buildCropFromGalleryIntent(mCropParams);
startActivityForResult(intent, CropHelper.REQUEST_CROP);

Clear the cached image if possible.

@Override
protected void onDestroy() {
    if (cropHandler.getCropParams() != null)
        CropHelper.clearCachedCropFile(cropHandler.getCropParams().uri);
    super.onDestroy();
}
