进入Android开发者官方链接作为教程，一步一步地从play store中查看并获得应用程序包的代码，如果存在或play store应用程序不存在，然后从web浏览器中打开应用程序。

Android开发者官方链接

https://developer.android.com/distribute/tools/promote/linking.html

链接到应用程序页面

从一个网站:https://play.google.com/store/apps/details?id=<package_name>

从Android应用程序:market://details?id = < package_name >

链接到产品列表

从一个网站:https://play.google.com/store/search?q=pub:<publisher_name>

从Android应用程序:market://search?q =酒吧:< publisher_name >

链接到搜索结果

从网站:https://play.google.com/store/search?q=<search_query>&c=apps

从Android应用程序:market://search?q = < seach_query >和c =应用

我结合了Berťák和Stefano Munarini的答案，创建了一个混合解决方案，处理这个应用程序的速率和显示更多的应用程序场景。

            // find all applications who can handle openPlayStoreIntent
            final List<ResolveInfo> otherApps = getPackageManager()
                    .queryIntentActivities(openPlayStoreIntent, 0);
            for (ResolveInfo otherApp : otherApps) {

                // look for Google Play application
                if (otherApp.activityInfo.applicationInfo.packageName.equals("com.android.vending")) {

                    ActivityInfo otherAppActivity = otherApp.activityInfo;
                    ComponentName componentName = new ComponentName(
                            otherAppActivity.applicationInfo.packageName,
                            otherAppActivity.name
                    );
                    // make sure it does NOT open in the stack of your activity
                    openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    // task reparenting if needed
                    openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
                    // if the Google Play was already open in a search result
                    //  this make sure it still go to the app page you requested
                    openPlayStoreIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                    // this make sure only the Google Play app is allowed to
                    // intercept the intent
                    openPlayStoreIntent.setComponent(componentName);
                    startActivity(openPlayStoreIntent);
                    isGooglePlayInstalled = true;
                    break;

                }
            }
            // if Google Play is not Installed on the device, open web browser
            if (!isGooglePlayInstalled) {

                Intent webIntent;
                if (showPublisherProfile) {
                    //Open Publishers Profile on web browser
                    webIntent = new Intent(Intent.ACTION_VIEW,
                            Uri.parse("http://play.google.com/store/search?q=pub:" + getPackageName()));
                } else {
                    //Open this App on web browser
                    webIntent = new Intent(Intent.ACTION_VIEW,
                            Uri.parse("https://play.google.com/store/apps/details?id=" + getPackageName()));
                }
                startActivity(webIntent);
            }
        }

使用

打开出版商配置文件

@OnClick (R.id.ll_more_apps) 公共无效showMoreApps() { openPlayStore(true，“Hitesh Sahu”); ｝

在PlayStore上打开应用页面

@OnClick (R.id.ll_rate_this_app) 公共无效openAppInPlayStore() { openPlayStore(假," "); ｝

如果你想单独打开谷歌Play(或任何其他应用程序)，以上所有答案都可以在同一个应用程序的新视图中打开谷歌Play:

Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.android.vending");

// package name and activity
ComponentName comp = new ComponentName("com.android.vending",
                                       "com.google.android.finsky.activities.LaunchUrlHandlerActivity"); 
launchIntent.setComponent(comp);

// sample to open facebook app
launchIntent.setData(Uri.parse("market://details?id=com.facebook.katana"));
startActivity(launchIntent);

重要的部分是实际上打开谷歌播放或任何其他应用程序独立。

我看到的大多数答案都使用了其他答案的方法，这不是我需要的，希望这能帮助到别人。

的问候。

您可以检查谷歌Play Store应用程序是否已安装，如果是这种情况，您可以使用“market://”协议。

final String my_package_name = "........."  // <- HERE YOUR PACKAGE NAME!!
String url = "";

try {
    //Check whether Google Play store is installed or not:
    this.getPackageManager().getPackageInfo("com.android.vending", 0);

    url = "market://details?id=" + my_package_name;
} catch ( final Exception e ) {
    url = "https://play.google.com/store/apps/details?id=" + my_package_name;
}


//Open the app page in Google Play store:
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
startActivity(intent);

这个链接将自动打开应用程序在市场://如果你是在Android和浏览器，如果你是在PC上。

对于费率应用:重定向到播放商店。 在Flutter中，你可以通过这样的平台通道进行操作

颤振部分:

 static const platform = const MethodChannel('rateApp');   // initialize 

onTap:平台。invokeMethod('urls'， {'android_id': 'com.xyz'})，

现在Android原生部分(Java):

private static final String RATEAPP = "rateApp";  // initialize variable

//现在在ConfigureFlutterEngine函数中:

        new MethodChannel(flutterEngine.getDartExecutor().getBinaryMessenger(), RATEAPP)
            .setMethodCallHandler(
                    (call, result) -> {               
                        if (call.method.equals("urls") && call.hasArgument("android_id")) {
                            String id = call.argument("android_id").toString();
                          
                            try {
                                startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("$uri" + id)));
                            } catch (android.content.ActivityNotFoundException anfe) {
                                startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + id)));
                            }
                            result.success("Done");
                        } else {
                            result.notImplemented();
                        }
                    }
            );
