FileProvider.getUriForFile:检查使用的权限

我正在使用一种简单的方法从Camera捕获图像,但是此时我收到以下错误报告:

Uri photoURI = FileProvider.getUriForFile(ReceiptActivity.this, "com.example.ves.gennaio3.fileprovider", pictureFile);

根据我的说法,它与使用的权限有关,但在清单中似乎是正确的。

AndroidManifest.xml

<provider
 android:name="android.support.v4.content.FileProvider"
 android:authorities="com.example.ves.gennaio3.fileprovider"
 android:exported="false"
 android:grantUriPermissions="true"
 android:readPermission="com.company.app.fileprovider.READ">
 <meta-data
  android:name="android.support.FILE_PROVIDER_PATHS"
  android:resource="@xml/file_list" />
</provider>

res / xml / file_list.xml

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-files-path name="my_images" path="my_images" />
</paths>

Java

public void captureImage(View view) {
    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (cameraIntent.resolveActivity(getPackageManager()) != null) {
        pictureFile = Helper.getPictureFile(ReceiptActivity.this);
        if (pictureFile != null) {
            Uri photoURI = FileProvider.getUriForFile(ReceiptActivity.this, "com.example.ves.gennaio3.fileprovider", pictureFile); //error here
            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
            startActivityForResult(cameraIntent, REQUEST_PICTURE_CAPTURE);
        }
    }
}

PS。我曾尝试提出一个苗条的问题,但看起来我的帖子大部分是代码,所以我添加了其他无用的文字以使其可发布。
