[当我尝试此代码时，当我尝试为安装Fille路径时出现错误->内容，然后安装时出现“解析软件包时出现问题”错误。
此代码位于android studio中的update click事件中。
String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
String fileName = "battlegame.apk";
destination += fileName;
final Uri uri = Uri.parse("file://" + destination);
//Delete update file if exists
File file = new File(destination);
if (file.exists()){
file.delete();
}
String url = downloadurl;
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDescription("Updating....");
request.setTitle("Battle Game");
request.setDestinationUri(uri);
final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
final long downloadId = manager.enqueue(request);
final String finalDestination = destination;
BroadcastReceiver onComplete = new BroadcastReceiver() {
public void onReceive(Context ctxt, Intent intent) {
Log.d("Update status", "Download completed "+uri.toString()+" id "+String.valueOf(downloadId));
Intent install = new Intent(Intent.ACTION_VIEW);
install.setDataAndType(Uri.fromFile(new File(finalDestination)),
"application/vnd.android.package-archive");
install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(install);
unregisterReceiver(this);
}
};
registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
我的下载正常运行，但是安装应用程序无法正常工作。下面的错误我得到。我为此粘贴了logcat。

从N开始，您无法将Uri file：//公开给其他应用，请改用FileProvider。
