unable to open the filePicker here is my code FilePickerBuilder.Companion.getInstance() .setActivityTitle(getString(R.string.selectTheKmlFile)) .enableCameraSupport(false) .enableDocSupport(true) .enableImagePicker(false) .enableSelectAll(false) .enableVideoPicker(false) .showFolderView(true) .setSelectedFiles(kmlFileList) .addFileSupport(getString(R.string.selectTheKmlFile), new String[] { "kml" }) .setMaxCount(1) .pickFile(this, REQUEST_CODE);

I had this issue but it was fixed when I added this line :

.sortDocumentsBy(SortingTypes.name)

my file picker is written as following code :

FilePickerBuilder.Companion.getInstance()
                .setMaxCount(1)
                .setSelectedFiles(new ArrayList<>())
                .setActivityTheme(R.style.LibAppTheme)
                .showFolderView(true)
                .sortDocumentsBy(SortingTypes.name)
                .pickFile(ChatActivity.this, REQUEST_CODE_DOC);
