问题

My app is being rejected due to your app(s) are using a content provider with an unsafe implementation of openfile.

@Override
    public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException {
        File privateFile = new File(uri.getPath());
        ParcelFileDescriptor desc = ParcelFileDescriptor.open(privateFile, ParcelFileDescriptor.MODE_READ_ONLY);

        return desc;
    }

 <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true"
            tools:replace="android:authorities">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_provider_paths"
                tools:replace="android:resource" />
 </provider>
