Android --- java.lang.SecurityException: Permission Denial: reading androidx.core.content.FileProvi

报错如下：

 java.lang.SecurityException: Permission Denial: reading androidx.core.content.FileProvider uri content://com.dfl.tingshu.fileProvider/downloadImage/iy34o5jtylscob1ma67oh9mwmggui5oj_326x326.jpeg from pid=25412, uid=1000 requires the provider be exported, or grantUriPermission()

之前我是通过以下方法将 uri 转 bitmap 的

Uri uri = null;
Bitmap bitmap = BitmapFactory.decodeStream(getContext().getContentResolver().openInputStream(uri))

报错之后修改成了以下转换方式

Uri uri = null;
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContext().getContentResolver(), uri)

具体原因还在进一步确认
