从android APP 链接到play商店

There are two general formats for links that are accessible to users on Android devices, The two formats trigger slightly different behaviors on the device:

• market://    Launches the Play Store app to load the target page.
• http://    Lets the user choose whether to launch the Play Store app or the browser to handle the request. If the browser handles the request, it loads the target page on the Google Play web site.

In general, you should use http:// format for links on web pages and market:// for links in Android apps.

If you want to link to your products from an Android app, create an Intent that opens an Google Play URL, as shown in the example below.

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=com.example.android"));
startActivity(intent);
