这是我获取的文件地址 content://com.tencent.mm.external.fileprovider/attachment/双模vd108 87.pdf

getContentResolver().openInputStream(uri) //读取uri文件，提示报错

报错信息如下

Permission Denial: reading android.support.v4.content.FileProvider uri content://com.tencent.mm.external.fileprovider/attachment/1_双模vd108 87.pdf from pid=14656, uid=10298 requires the provider be exported, or grantUriPermission()
