Android:IllegalArgumentException:无法找到包含/data/data/的已配置根目录

Question

刚接触到适用于 Android 的 Glide 图像加载库。使用此处的代码:https://github.com/bumptech/glide/issues/459

完整项目在这里: https://github.com/mhurwicz/glide02

当我在 Android Studio 的模拟器中运行应用程序时出现以下异常:

java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/com.example.glide02/cache/image_manager_disk_cache/5a992029460eed14244e8b970d969d45518b2f7ac10f71eb26bd0aaf7c3bcf06.0

其余的消息是:

at android.support.v4.content.FileProvider$SimplePathStrategy.getUriForFile(FileProvider.java:711)
                  at android.support.v4.content.FileProvider.getUriForFile(FileProvider.java:400)

                  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)

错误发生在FileProvider.getUriForFile()

@Override protected void onPostExecute(File result) {
    if (result == null) { return; }
    Uri uri = FileProvider.getUriForFile(context, context.getPackageName(), result);
    share(uri); // startActivity probably needs UI thread
}

我已经查看了与此错误相关的其他几个问题，但看不出它们与我的案例有什么关系，这可能是因为我对这整个领域不熟悉。

任何帮助将不胜感激。

这是出现上述方法的类的完整代码:

class ShareTask extends AsyncTask<String, Void, File> {
private final Context context;

public ShareTask(Context context) {
    this.context = context;
}
@Override protected File doInBackground(String... params) {
    String url = params[0]; // should be easy to extend to share multiple images at once
    try {
        return Glide
                .with(context)
                .load(url)
                .downloadOnly(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL)
                .get() // needs to be called on background thread
                ;
    } catch (Exception ex) {
        Log.w("SHARE", "Sharing " + url + " failed", ex);
        return null;
    }
}
@Override protected void onPostExecute(File result) {
    if (result == null) { return; }
    Uri uri = FileProvider.getUriForFile(context, context.getPackageName(), result);
    share(uri); // startActivity probably needs UI thread
}

private void share(Uri result) {
    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("image/jpeg");
    intent.putExtra(Intent.EXTRA_SUBJECT, "Shared image");
    intent.putExtra(Intent.EXTRA_TEXT, "Look what I found!");
    intent.putExtra(Intent.EXTRA_STREAM, result);
    context.startActivity(Intent.createChooser(intent, "Share image"));
}

在我的例子中，这是 filepath.xml 中的解决方案

    <paths>
    <root-path name="root" path="." />
</paths>
