“评价此应用程序"-手机上 Google Play 商店应用程序中的链接

问题描述

我想在 Android 应用中添加评价此应用"链接，以便在用户手机上的 Google Play 商店应用中打开应用列表.

I'd like to put a "Rate This App"-link in an Android App to open up the app-listing in the user's Google Play store app on their phone.

1. 我必须编写什么代码才能在手机上的 Google Play 商店应用中创建 market:// 或 http://-链接?
2. 您将代码放在哪里?
3. 有人有这方面的示例实现吗?
4. 您是否必须指定 market:// 或 http:// 链接将放置在哪个屏幕上，哪个最好使用 - market:// 还是 http://?

1. What code do I have to write to create the market:// or http://-link open in the Google Play store app on the phone?
2. Where do you put the code?
3. Does anyone have a sample implementation of this?
4. Do you have to specify the screen where the market:// or http:// link will be placed, and which is the best to use - market:// or http://?

推荐答案

我使用以下代码从我的应用打开 Play 商店:

I open the Play Store from my App with the following code:

            val uri: Uri = Uri.parse("market://details?id=$packageName")
            val goToMarket = Intent(Intent.ACTION_VIEW, uri)
            // To count with Play market backstack, After pressing back button, 
            // to taken back to our application, we need to add following flags to intent. 
            goToMarket.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY or
                    Intent.FLAG_ACTIVITY_NEW_DOCUMENT or
                    Intent.FLAG_ACTIVITY_MULTIPLE_TASK)
            try {
                startActivity(goToMarket)
            } catch (e: ActivityNotFoundException) {
                startActivity(Intent(Intent.ACTION_VIEW,
                        Uri.parse("http://play.google.com/store/apps/details?id=$packageName")))
            }

选项 2:是使用resolveActivity而不是try..catch

Option 2: is to use resolveActivity instead of try..catch

if (sendIntent.resolveActivity(getPackageManager()) != null) {
     startActivity(chooser);
} else {
    openUrl();
}
