SmartImagePicker

SmartImagePicker copied to clipboard

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
