我有一个Android应用程序为我公司自成立一个私人的应用程序编写的，它不是在Android Market。我希望能有定期的检查应用程序的更新，如果有一个通知用户，并开始下载/安装更新。

I have an android app written for my company and since its a private app, it is not in the android market. I'd like to be able to have the app check periodically for an update and if there is one notify the user and start downloading / installing the update.

是否有像这样的例子在那里？

Is there an example of something like this out there?

推荐答案

在你的应用程序开始检查可用的版本，你可以使用一个AlertDialog要求进行升级。

at the start of your app check the available version, the you can use an AlertDialog to ask for the upgrade.

和这是一个AlertDialog例子::

and this is an AlertDialog example::

    if (ConfigXML_app_version> myapp_version){
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Upgrade");
        builder.setMessage("Update available, ready to upgrade?");
        builder.setIcon(R.drawable.icon);
        builder.setCancelable(false);
        builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse(app_link));
                startActivity(intent);               
                finish();
            }
        });
        builder.setNegativeButton("Nop", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                dialog.cancel();
            }
        });
        AlertDialog alert = builder.create();
        alert.show();

    }
