我这样设置了限制只允许json文件的选择，
FileDialog.build()
.setPath(avaliableStoragePath)
.setMimeTypes(new String[]{"application/json"})
但是代码报如下错误：
java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.isEmpty()' on a null object reference
at com.kongzue.filedialog.adapter.FileAdapter.getMimeType(FileAdapter.java:146)
at com.kongzue.filedialog.adapter.FileAdapter.isSelectMimeType(FileAdapter.java:132)
at com.kongzue.filedialog.adapter.FileAdapter.getView(FileAdapter.java:107)

请问这是什么问题呢？
