Cropimage

Call this method to run CropImage activity

private void runCropImage() {

    // create explicit intent
    Intent intent = new Intent(this, CropImage.class);

    // tell CropImage activity to look for image to crop 
    String filePath = ...;
    intent.putExtra(CropImage.IMAGE_PATH, filePath);

    // allow CropImage activity to rescale image
    intent.putExtra(CropImage.SCALE, true);

    // if the aspect ratio is fixed to ratio 3/2
    intent.putExtra(CropImage.ASPECT_X, 3);
    intent.putExtra(CropImage.ASPECT_Y, 2);

    // start activity CropImage with certain request code and listen
    // for result
    startActivityForResult(intent, REQUEST_CODE_CROP_IMAGE);
}

Waiting for result

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

    if (resultCode != RESULT_OK) {

        return;
    }  

    switch (requestCode) {

        case REQUEST_CODE_CROP_IMAGE:

            String path = data.getStringExtra(CropImage.IMAGE_PATH);

            // if nothing received
            if (path == null) {

                return;
            }

            // cropped bitmap
            Bitmap bitmap = BitmapFactory.decodeFile(mFileTemp.getPath());

            break;
    }
    super.onActivityResult(requestCode, resultCode, data);
}

Building with Gradle

To build with gradle, make sure you have installed the gradle wrapper in the top level directory. On my computer this is typically done (from the root of this project) with a:

cp -Rv /opt/android-studio/sdk/tools/templates/gradle/wrapper/* .

Make sure to adjust the path to whereever you installed Android Studio.

After doing this, to build issue the following command (again from the root of this project):

./gradlew assembleDebug

To install the example a running emulator or device, do a:

adb install -r ./simple-crop-image-example/build/apk/simple-crop-image-example-debug-unaligned.apk
