判断手机是否安装应用市场：



public static boolean hasAnyMarketInstalled(Context context) {
        Intent intent = new Intent();
        intent.setData(Uri.parse("market://details?id=android.browser"));
        List<ResolveInfo> list = context.getPackageManager()
                .queryIntentActivities(intent,
                        PackageManager.MATCH_DEFAULT_ONLY);
        return 0 != list.size();
    }
