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.

Sample

Usage

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

IMPORTANT NOTICE!

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);

Step 1

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);
}

Step 2

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() {
    // ...
}

Step 3

Launch a request to crop photos.

Crop from camera

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

Crop from gallery

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

Step 4

Clear the cached image if possible.

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