Android:FileProvider IllegalArgumentException无法找到包含/data/data/**/files/Videos/final.mp4的配置根目录 [英] Android: FileProvider IllegalArgumentException Failed to find configured root that contains /data/data/**/files/Videos/final.mp4

问题描述

我正在尝试使用 FileProvider 从私有路径播放视频.

I am trying to use FileProvider to play a video from private path.Facing

java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/XXXXX(Package)/files/Videos/final.mp4

代码:

<paths>
    <files-path path="my_docs" name="Videos/" />
</paths>

Java代码:

File imagePath = new File(getFilesDir(), "Videos");
File newFile = new File(imagePath, "final.mp4");
Log.d(TAG, "-------------newFile:"+newFile.exists());//True here
//Exception in below line
Uri contentUri = FileProvider.getUriForFile(this,"com.wow.fileprovider", newFile);

Manifest.xml

Manifest.xml

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.wow.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">

<meta-data
    android:name="android.support.FILE_PROVIDER_PATHS"
    android:resource="@xml/file_paths" />

有任何线索吗?

谢谢尼兹

推荐答案

您的名称和 path 被翻转了. name 是 Uri 中的内容， path 是文件系统根中的相对位置.

You have your name and your path flipped. name is what goes in the Uri, and path is the relative location within the root on the filesystem.

继续:

<paths>
    <files-path name="my_docs" path="Videos/" />
</paths>
