是否有可能通过数据URL分享Android上的图像？

问题描述

是否有可能与code这样的事？

分享图片

 意图份额=新意图（Intent.ACTION_SEND）;
share.setData(Uri.parse(\"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAAXNSR0IArs4c6QAAAARnQU1BAACx\"

startActivity（Intent.createChooser（份额，的getString（R.id.menu_share）））;
 

我的目标是让我的应用程序不需要权限写入到存储，而是要能够分享其动态创建的图像。有没有办法做到这一点？

解决方案

No, because ACTION_SEND does not use the Uri. It uses EXTRA_TEXT or EXTRA_STREAM.

Create a ContentProvider to serve the file, then put the Uri pointing to your file within your provider in EXTRA_STREAM. You may be able to protect the provider with a custom permission and allow the sending activity temporary access to it via FLAG_GRANT_READ_URI_PERMISSION, though I have only tried that with Intent structures that use the actual Uri (e.g., setData()) instead of via an extra like EXTRA_STREAM.

This sample project demonstrates this technique using ACTION_VIEW (note: requires a device with a PDF viewer installed to truly work).
