推荐答案

这是可以共享文件（图像含）从资产通过自定义文件夹的ContentProvider

It is possible to share files (images including) from the assets folder through a custom ContentProvider

您需要扩展的ContentProvider ，在你的清单中注册并实现openAssetFile方法。然后，您可以通过尤里斯评估的资产。

You need to extend ContentProvider, register it in your manifest and implement the openAssetFile method. You can then assess the assets via Uris.

添加到您的清单。

<provider android:name="yourclass.that.extendsContentProvider"
        android:authorities="com.yourdomain.whatever"/>

例如类，

   @Override
    public AssetFileDescriptor openAssetFile(Uri uri, String mode) throws FileNotFoundException {
        AssetManager am = getContext().getAssets();
        String file_name = uri.getLastPathSegment();

        if(file_name == null) 
            throw new FileNotFoundException();
        AssetFileDescriptor afd = null;
        try {
            afd = am.openFd(file_name);
        } catch (IOException e) {
            e.printStackTrace();
        }

return afd;
}

做参考，
太容易使用，ContentProvider的到送
