为什么我在Android中收到“接收广播意图错误”？

Question

此功能完善了可以正常使用的API 22，但不能正常使用API​​ 23和API 24或更高版本。我尝试使用其他标志安装意图，但未成功。我不能再给小费什么问题了。我尝试修改意图内容，但不起作用...

也许程序不知道何时下载完complette？

请帮助我什么问题？谢谢！！

 public void updateVersion(String apkurl){   //apkurl: http://something.com/xyz.apk

    String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
    String fileName = "AppName_1.apk"; //Download File name
    destination += fileName;
    final Uri uri = Uri.parse("file://" + destination); //Download file storage uri

    //Delete update file if exists
    File file = new File(destination);

    if (file.exists()) {
        //file.delete() - test this, I think sometimes it doesnt work
        file.delete();
    }

    file.setReadable(true, false);
    //set downloadmanager
    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(apkurl));
    request.setDescription(this.getString(R.string.notification_description));
    request.setTitle(this.getString(R.string.app_name));

    //set destination
    request.setDestinationUri(uri);

    // get download service and enqueue file
    final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
    final long downloadId = manager.enqueue(request);

    //set BroadcastReceiver to install app when .apk is downloaded
    final String finalDestination = destination;
    Toast.makeText(getApplicationContext(),
            finalDestination,
            Toast.LENGTH_LONG).show();
    BroadcastReceiver onComplete = new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {

            String installerPackageName = getIntent().getStringExtra(Intent.EXTRA_INSTALLER_PACKAGE_NAME);
            Intent install = new Intent(Intent.ACTION_VIEW);
            install.putExtra(Intent.EXTRA_INSTALLER_PACKAGE_NAME, installerPackageName);
            install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_GRANT_READ_URI_PERMISSION);
            install.setDataAndType(uri, manager.getMimeTypeForDownloadedFile(downloadId));
            startActivity(install);

            unregisterReceiver(this);
            finish();
        }
    };
    //register receiver for when .apk download is compete
    registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
}

错误：
