我需要检查Android Market是否像这样安装

    /*
     * Test for existence of Android Market
     */
    boolean androidMarketExists = false;
    try{
        ApplicationInfo info = getPackageManager()
                             .getApplicationInfo("com.google.process.gapps", 0 );
        //application exists
        androidMarketExists = true;
    } catch( PackageManager.NameNotFoundException e ){
        //application doesn't exist
        androidMarketExists = false;
    }

但我不知道com.google.process.gapps是否是具有Android市场的软件包.
