我有一个android.intent.action.SEND
带有图片 mime 类型的意图过滤器的活动。
一旦用户与我的活动(UploadActivity)分享图片(特别是来自下载管理器),活动将检查用户是否登录。如果没有,它将存储原始意图(带有EXTRA_STREAM
)并将用户发送到 LoginActivity . 一旦该用户登录,他将被带回 UploadActivity 并使用原始保存的意图。
现在,即使在恢复了原始意图之后,我也得到了一个java.lang.SecurityException: Permission Denial: reading com.android.providers.downloads.DownloadProvider uri...
.
我明白我为什么会得到这个。因为我没有原意的临时权限。
