How to use

1. Check Permission

You have to grant WRITE_EXTERNAL_STORAGE permission from user.
If your targetSDK version is 23+, you have to check permission and request permission to user.
Because after Marshmallow(6.0), you have to not only decalare permisions in AndroidManifest.xml but also request permissions at runtime.
There are so many permission check library in Android-Arsenal

2. Start TedBottomPicker

TedBottomPicker class extend BottomSheetDialogFragment.
TedBottomPicker.Builder make new TedBottomPicker().
After then, you can show TedBottomPicker

     TedBottomPicker tedBottomPicker = new TedBottomPicker.Builder(MainActivity.this)
                                .setOnImageSelectedListener(new TedBottomPicker.OnImageSelectedListener() {
                                    @Override
                                    public void onImageSelected(Uri uri) {
                                        // here is selected uri
                                    }
                                })
                                .create();

     tedBottomPicker.show(getSupportFragmentManager());

If you want select multi image, you can use OnMultiImageSelectedListener

 TedBottomPicker bottomSheetDialogFragment = new TedBottomPicker.Builder(MainActivity.this)
                               .setOnMultiImageSelectedListener(new TedBottomPicker.OnMultiImageSelectedListener() {
                                   @Override
                                   public void onImagesSelected(ArrayList<Uri> uriList) {
                                       // here is selected uri list
                                   }
                               })
                                .setPeekHeight(1600)
                                .showTitle(false)
                                .setCompleteButtonText("Done")
                                .setEmptySelectionText("No Select")
                                .create();

                        bottomSheetDialogFragment.show(getSupportFragmentManager());

Don't forget!!
You have to declare setOnImageSelectedListener() or OnMultiImageSelectedListener() in Builder.
This listener will pass selected Uri/UriList.
