Java 文件提供程序IllegalArgumentException

我尝试打开pdf文件

AndroidManifest.xml

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.interactivegroup.android.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />

    </provider>

我总是抓住这个例外

Caused by: java.lang.IllegalArgumentException: Failed to find configured root that contains /Download/Киоски.pdf

我找不到足够的理由来解释什么是错的

对不起，我的英语不好((((

谢谢。

我想将文件_path.xml更改为：

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

它可能的复制品没有改变任何东西(

Caused by: java.lang.IllegalArgumentException: Failed to find configured root that contains /Download/Киоски.pdf

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

Uri contentUri = getUriForFile(getContext(), "com.interactivegroup.android.fileprovider", newFile);
