Question

我正在尝试使用隐式意图ACTION_SEND将Chrome浏览器中的图像共享到我的应用程序。

在共享搜索到的图片时，应用会收到内容URI的意图，如下所示：content：//com.android.chrome.FileProvider/images/screenshot/1457448067808912906311.jpg

使用 ContentResolver 和 openInputStream（）来读取与内容Uri相关联的字节数，它会导致应用程序崩溃安全异常：权限拒绝

这是堆栈跟踪：

过去几天我编写此功能时就已经开始工作了。我从这个SO question的答案得到了帮助。有人可以建议现在可能导致此问题的原因吗？

Answer 1

请确保您尝试从Android Manifest中设置ACTION_SEND的同一活动中获取图片。上述问题最可能的原因

通过openInputStream（）
