下载后的apk文件解析软件包时出现问题 about open_file HOT 7 CLOSED

我也遇到了，apk文件不要放在CacheDirectorye 换到SD卡 ExternalStorageDirectory 就好了。

from open_file.

首先确定apk包有没有问题，建议先在文件管理器里找到apk点击安装试试，然后确定apk所在路径是否正确

from open_file.

我保存到位置就是ExternalStorageDirectory目录，但是打开之后，依然提示软件包解析问题

final directory = await getExternalStorageDirectory();
    String _localPath = directory.path;
    final taskId = await FlutterDownloader.enqueue(
      url: 'http://www.ionic.wang/jdshop.apk',
      savedDir: _localPath,
      showNotification:
          true, // show download progress in status bar (for Android)
      openFileFromNotification:
          true, // click on notification to open downloaded file (for Android)
    );
    FlutterDownloader.registerCallback(downloadCallback);
    // 打开文件
    OpenFile.open('${_localPath}/jdshop.apk');

开启调试后，显示到调试信息。

确认2点
1、是否是android10以上设备（存储机制变更）
2、是否是真实路径

from open_file.

有没有解决呢，我也出现了这个问题？
