我正在尝试通过ACTION_SEND意图共享存储在getExternalFilesDir()中的文件。我使用FileProvider授予权限并创建uri。弹出的选择器包括Signal,Gmail和云端硬盘。如果我选择云端硬盘,则操作成功,并且文件已正确上传到我的帐户。如果我选择信号,它会成功,并且我的朋友会获取文件。如果我选择Gmail,则该操作似乎成功,并且我看到一条带有正确名称和大小的附件的邮件。我填写“收件人”字段,然后单击发送,作曲家消失了,但是没有发送或保存任何消息,并且出现logcat错误:> java.lang.IllegalStateException:在发送草稿时发现无效的附件。
这是清单:
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
这是provider_paths:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-files-path
name="data"
path="."/>
</paths>
这是在MainActivity中构建和启动意图的地方:
val uri = getUriForFile(
applicationContext,
"${BuildConfig.APPLICATION_ID}.fileprovider",
file
)
Log.d(TAG, "send uri: " + uri)
Intent(Intent.ACTION_SEND)
.apply {
//setType("text/plain") // works for drive, but fails for email
setType("application/zip")
putExtra(Intent.EXTRA_STREAM, uri)
putExtra(Intent.EXTRA_SUBJECT, "Armonitor Record:" + file.nameWithoutExtension)
putExtra(Intent.EXTRA_TEXT, "See attached...")
setFlags(FLAG_GRANT_READ_URI_PERMISSION.or( FLAG_GRANT_WRITE_URI_PERMISSION))
}
.also {
startActivity(Intent.createChooser(it, "share file with"));
}
我知道fileprovider权限正在起作用,因为当我破坏它时,在显示选择器之前会出现错误。我尝试手动向该意图的任何使用者授予权限,以防该权限仅适用于setData uri。我尝试了各种文件类型,包括“应用程序/八进制”,“文本/纯文本”,“消息/ rfc822”。我尝试发送的文件在0.2到38 kB之间,并且我尝试过.txt和.zip文件。我确实注意到,如果我将“从”地址更改为其他gmail帐户,则附件将完全消失。无需附件即可成功发送电子邮件。我的手机上没有配置其他电子邮件客户端。
这是gmail发出的logcat消息,试图发送一个类型为 Gmail认为“无效附件”是什么?如何通过Gmail共享这些文件? 我听说gmail设置了允许的附件类型和大小的设置,但是我不确定如何找到它们,或者这是否是这里发生的事情。 感谢您可能有任何想法。2019-07-05 11:29:22.944 11320-13752 W/Gmail: ComposeActivity:Failed to retrieve reference message with uri=null.

答案 0 :(得分:0)
好吧,这可能太愚蠢了,无法提供帮助,但是我确实解决了这个问题。就是我的provider_paths文件仅列出
<external-files-path
name="data"
path="."/>
我将zip文件保存在一个子文件夹中,所以我需要添加
<external-files-path
name="zip"
path="./zip" />
我不知道为什么它可以通过Signal和Drive共享,但是Gmail更挑剔。但现在它对所有人都有效,是的!

如果您也将其添加为 ClipData
,则权限授予将成功:
yourIntent.clipData = ClipData.newUri(context.contentResolver, fileName, contentUri)
原因是 Intent.FLAG_GRANT_READ_URI_PERMISSION
仅适用于 Intent.data
和 Intent.clipData
,不适用于额外的,除非已明确授予 uri 权限(不方便),或已授予还添加一个 ClipData
。
