Android 遍历手机应用，跳转应用市场详情页面

首先遍历手机内应用，找到需要的应用包名：

    /**
     * 遍历手机内应用包名
     * @param context
     */
    public static void loadApps(Context context) {
        Intent intent = new Intent(Intent.ACTION_MAIN, null);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        List<ResolveInfo> apps = context.getPackageManager().queryIntentActivities(intent, );
        //for循环遍历ResolveInfo对象获取包名和类名
        for (int i = ; i < apps.size(); i++) {
            ResolveInfo info = apps.get(i);
            String packageName = info.activityInfo.packageName;
            CharSequence cls = info.activityInfo.name;
            CharSequence name = info.activityInfo.loadLabel(context.getPackageManager());
            Log.e("wgh！！！！！", name + "----" + packageName + "----" + cls);
        }
    }

对包名进行应用市场详情页面跳转：

    /**
     * 启动到app详情界面
     *
     * @param appPkg
     *            App的包名
     * @param marketPkg
     *            应用商店包名 ,如果为""则由系统弹出应用商店列表供用户选择,否则调转到目标市场的应用详情界面，某些应用商店可能会失败
     */
    public static void launchAppDetail(Context context,String appPkg, String marketPkg) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse("market://details?id=" + appPkg));
        String[] keys = getKeys(context);
        if (keys != null) {
            intent.setClassName(keys[], keys[]);
        }
        //修复某些老手机会因为找不到任何市场而报错
        if (isIntentAvailable(context, intent)) {
            context.startActivity(intent);
