Simplified abstraction over Android Image Cropper library to pick images from gallery or camera and crop them if needed.

Note

This library is currently unsupported because I've switched my focus to Flutter and don't plan fixing any bugs any time soon

Usage

Add this line to build.gradle

compile 'com.myhexaville:smart-image-picker:1.0.4'

Create new instance and save it as field

imagePicker = new ImagePicker(this, /* activity non null*/
                null, /* fragment nullable*/
                imageUri -> {/*on image picked */
                    imageView.setImageURI(imageUri);
                })
                .setWithImageCrop(
                        1 /*aspect ratio x*/
                        1 /*aspect ratio y*/);

If calling from Activity

Override Activity's methods to delegate permissions to ImagePicker and resulting image

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    imagePicker.handleActivityResult(resultCode,requestCode, data);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    imagePicker.handlePermission(requestCode, grantResults);
}

Open Picker

There's two methods available

imagePicker.openCamera();
imagePicker.choosePicture(true /*show camera intents*/);

First one opens camera directly, second shows an intent picker, where user picks from desired application. You can include/exclude camera intents with boolean.

That's it, if you don't need to crop image, don't call setWithImageCrop() in the chain. By default it's disabled. And if you want to get a file after you picked image, you can get it with this method

File file = imagePicker.getImageFile();

If calling from Fragment

Create instance

imagePicker = new ImagePicker(getActivity(),
                this,
                imageUri -> {/*on image picked */
                    imageView.setImageURI(imageUri);
                })
                .setWithImageCrop(
                        1 /*aspect ratio x*/
                        1 /*aspect ratio y*/);

Overriden methods should be in your Fragment

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    imagePicker.handleActivityResult(resultCode, requestCode, data);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    imagePicker.handlePermission(requestCode, grantResults);
}

But your fragment won't get activity result callback itself. You need to call it manually. Add this code to activity that hosts your fragment

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    List<Fragment> fragments = getSupportFragmentManager().getFragments();
    if (fragments != null) {
        for (Fragment f : fragments) {
            if (f instanceof YourFragment) {
                f.onActivityResult(requestCode, resultCode, data);
            }
        }
    }
}

You can get a sample app here

You don't need to add any permissions to manifest, everything is merged automatically from library's manifest file
