为什么我不能分享我的android应用程序的pdf文件？

Question

我在用

contentUri = ContentUris.withAppendedId(MediaStore.Files.getContentUri("external"), 
    data.id);
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
    shareIntent.putExtra(Intent.EXTRA_TEXT, body);
    shareIntent.setType(type); // application/pdf
    shareIntent.putExtra(Intent.EXTRA_STREAM, contentUri);
    shareIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    return shareIntent;

它正被分享给WhatsApp，当我选择一个联系人来分享我的文件时，WhatsApp中的祝酒词说：“共享失败。请再试一次。”

这是一个特定于设备的问题，发生在OEM中，如Oneplus、Redmi、Oppo，但在三星的Pixel工作得很好。

检查whatsapp日志中的问题如下：

编辑:附加logcat

更改putExtra：

putExtra(Intent.EXTRA_STREAM,FileProvider.getUriForFile(this,"${BuildConfig.APPLICATION_ID}.provider", file))
