推荐答案

您有几个问题。

首先， file：/// assets / 不是有效的 Uri on任何版本的Android。您自己的应用程序可以通过 file：/// android_asset / 引用自己的资产。

First, file:///assets/ is not a valid Uri on any version of Android. Your own application can refer to its own assets via file:///android_asset/.

其次，只有你可以通过 file：/// android_asset / 访问您自己的资产 - 您无法将这样的 Uri 传递给第三位 - 派对应用。将文件从资产复制到内部存储并使用 FileProvider ，或者您可以尝试我的 StreamProvider 并尝试直接从 assets / 中分享数据。

Second, only you can access your own assets via file:///android_asset/ -- you cannot pass such a Uri to third-party apps. Either copy the file from assets into internal storage and use FileProvider, or you can try my StreamProvider and try to share the data straight out of assets/.

第三，无法保证设备上存在 com.whatsapp ，或 com.whatsapp 将支持 ACTION_SEND file：/// Uri MIME类型为 image / * 的值，因此您可能会因 ActivityNotFoundException 。

Third, there is no guarantee that com.whatsapp exists on the device, or that com.whatsapp will support ACTION_SEND of file:/// Uri values with a MIME type of image/*, and so you may crash with an ActivityNotFoundException.

第四，用户可能希望通过WhatsApp以外的其他方式分享此图像。 请允许用户分享的位置用户想要，从 Intent 中删除​​ setPackage（）调用。

Fourth, the user might want to share this image via some other means than WhatsApp. Please allow the user to share where the user wants, by removing the setPackage() call from your Intent.
