open link of google play store in mobile version android

You'll want to use the specified market protocol:

final String appPackageName = "com.example"; // Can also use getPackageName(), as below
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));

Keep in mind, this will crash on any device that does not have the Market installed (the emulator, for example). Hence, I would suggest something like:

final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException anfe) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + appPackageName)));
}

While using getPackageName() from Context or subclass thereof for consistency (thanks @cprcrack!). You can find more on Market Intents here: link.

Below code may helps you for display application link of google play sore in mobile version.

For Application link :

Uri uri = Uri.parse("market://details?id=" + mContext.getPackageName());
Intent myAppLinkToMarket = new Intent(Intent.ACTION_VIEW, uri);

  try {
        startActivity(myAppLinkToMarket);

      } catch (ActivityNotFoundException e) {

        //the device hasn't installed Google Play
        Toast.makeText(Setting.this, "You don't have Google Play installed", Toast.LENGTH_LONG).show();
              }

For Developer link :

Uri uri = Uri.parse("market://search?q=pub:" + YourDeveloperName);
Intent myAppLinkToMarket = new Intent(Intent.ACTION_VIEW, uri);

            try {

                startActivity(myAppLinkToMarket);

            } catch (ActivityNotFoundException e) {

                //the device hasn't installed Google Play
                Toast.makeText(Settings.this, "You don't have Google Play installed", Toast.LENGTH_LONG).show();

            } 

You can check if the Google Play Store app is installed and, if this is the case, you can use the "market://" protocol.

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);

You can use Android Intents library for opening your application page at Google Play like that:

Intent intent = IntentUtils.openPlayStore(getApplicationContext());
startActivity(intent);
