Question

尝试将Uri实例作为附件附加到电子邮件意图时，我收到了FileUriExposedException。

我使用FileProvider模式处理Camera Intent结果，其配置如下：

<provider
    android:name="android.support.v4.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>

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

但是，当我尝试将结果Uri实例附加到Email意图时，我得到了意想不到的结果。见下文（非常感谢帮助！）：

final Uri pAttachment = getParentActivity().takeScreenshot();

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/html");
intent.putExtra(Intent.EXTRA_EMAIL,     new String[]{pEmailTo});
intent.putExtra(Intent.EXTRA_SUBJECT,   pSubject);
intent.putExtra(Intent.EXTRA_TEXT,      Html.fromHtml(pBody));
intent.putExtra(Intent.EXTRA_STREAM,    pAttachment);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

pContext.startActivity(intent);
