  • Enable/disable camera from LassiOption
  • You can open System Default view for file selection by using MediaType.FILE_TYPE_WITH_SYSTEM_VIEW



  • Step 1. Add the JitPack repository in your project build.gradle:

        allprojects {
            repositories {
                maven { url 'https://jitpack.io' }


    If Android studio version is Arctic Fox then add it in your settings.gradle:

       dependencyResolutionManagement {
            repositories {
                maven { url 'https://jitpack.io' }
  • Step 2. Add the dependency in your app module build.gradle:

        dependencies {
            implementation 'com.github.Mindinventory:Lassi:X.X.X'


  • Step 1. To open a app color theme view then add Lassi in to your activity class:

            val intent = Lassi(this)
                .with(LassiOption.CAMERA_AND_GALLERY) // choose Option CAMERA, GALLERY or CAMERA_AND_GALLERY
                .setMediaType(MediaType.VIDEO) // MediaType : VIDEO IMAGE, AUDIO OR DOC
                .setCompressionRation(10) // compress image for single item selection (can be 0 to 100)
                .setMinTime(15) // for MediaType.VIDEO only
                .setMaxTime(30) // for MediaType.VIDEO only
                .setSupportedFileTypes("mp4", "mkv", "webm", "avi", "flv", "3gp") // Filter by limited media format (Optional)
                .setMinFileSize(100) // Restrict by minimum file size 
                .setMaxFileSize(1024) //  Restrict by maximum file size
                .disableCrop() // to remove crop from the single image selection (crop is enabled by default for single image)
                 * Configuration for  UI
                .setGalleryBackgroundColor(R.color.colorGrey)//Customize background color of gallery (default color is white)
                .setCropType(CropImageView.CropShape.RECTANGLE) // choose shape for cropping after capturing an image from camera (for MediaType.IMAGE only)
                .setCropAspectRatio(1, 1) // define crop aspect ratio for cropping after capturing an image from camera (for MediaType.IMAGE only)
                .enableFlip() // Enable flip image option while image cropping (for MediaType.IMAGE only)
                .enableRotate() // Enable rotate image option while image cropping (for MediaType.IMAGE only)
                .enableActualCircleCrop() // Enable actual circular crop (only for MediaType.Image and CropImageView.CropShape.OVAL)

    OR To open a system default view then add Lassi in to your activity class:

            val intent = Lassi(this)
                "jpg", "jpeg", "png", "webp", "gif", "mp4", "mkv", "webm", "avi", "flv", "3gp",
                "pdf", "odt", "doc", "docs", "docx", "txt", "ppt", "pptx", "rtf", "xlsx", "xls"
                )  // Filter by required media format (Mandatory)
  • Step 2. Get Lassi result in ActivityResultCallback lambda function.

        private val receiveData =
                registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {
                    if (it.resultCode == Activity.RESULT_OK) {
                        val selectedMedia =
                            it.data?.getSerializableExtra(KeyUtils.SELECTED_MEDIA) as ArrayList<MiMedia>
                        if (!selectedMedia.isNullOrEmpty()) {
                            ivEmpty.isVisible = selectedMedia.isEmpty()

Document access permission note

If Android device SDK is >= 30 and wants to access document (only for choose the non media file) then add android.permission.MANAGE_EXTERNAL_STORAGE permission in your app otherwise library won't allow to access documents. Kindly check sample app for more detail. If you don't want to give Manage External Storage permission and wants to get files with system default view then You can use OR option from Step 1 and give required file type of document.

MediaType.FILE_TYPE_WITH_SYSTEM_VIEW (for System Default View)

Using this MediaType you can choose multiple files from system default view. You can't set max count limit for file choose. Give file type into setSupportedFileTypes and you can choose only those types of file from system view.
