At some stage, during the design of your mobile app, you’re going to have to make a decision about how you will develop the app. Your choices include native apps, hybrid apps and responsive web sites and the decision you make will affect the final product. Learning to make the right decision requires understanding the way each type of development works and how it affects the final product.

There are three main options for creating a mobile app. You can create a native app, a hybrid app or a mobile responsive website which offers similar functionality to an app. Each option has its advantages and disadvantages and it’s important to understand these in detail before committing to a particular development path. The path you choose is likely to be informed by the resources available to you and what you’re trying to achieve.

What is a Native App?

A native app is designed to run on a specific mobile operating system. It won’t run on other mobile operating systems. So, for example, if you were going to develop a native app for iOS you’d do the development in Swift.

The biggest advantages to native apps are that they can normally access all the functionality of the chosen device easily and that they are more likely, if developed properly, to run without error on the device.

However, this comes with a trade-off. A native app cannot be run on a device which doesn’t utilize the same operating system. That means if you want your app to run on Windows, iOS 7, and Android – you’re going to have to develop the app 3 times, once for each operating system. This can make the development process both slower and more expensive.

Many companies will develop their app for a single operating system when they choose the native route. If the app is successful in that environment; they will then go back and recreate it for other operating systems. It’s worth noting that at this moment in time – iOS 7 apps are, generally, more profitable than apps released for other environments.

What is a Hybrid App?

A hybrid app is designed to work on multiple platforms. It’s written using a single standard code language (such as C# or a combination of HTML5 and Javascript) and then compiled to be executed on each platform. Device specific interactions will normally be managed by the use of plugins for that operating system.Author/Copyright holder: Salesforce.com,inc.

The biggest advantage of hybrid apps is that they enable support for multiple operating systems at a more cost effective price point than developing multiple native apps. Users, as long as the development is done well, will not normally be able to distinguish whether an app is native or hybrid. In fact users, in general, don’t care about how your app is developed – they just care if it works on their device and does what they expect it to do.

There are disadvantages to hybrid app development. It can present serious challenges if the app requires complex interaction from the device – there’s a limit to what plugins can achieve on this front. The costs of supporting a hybrid application may be higher than the costs of supporting a native application too.

What is a Responsive Website?

A responsive website can deliver similar functionality to an app. In fact, with a little creativity you can keep the differences to a minimum and ensure that the home page jumps straight into a “full screen” display.

Responsive websites will be developed using HTML 5 and Javascript. Typically developers will take a “mobile first” approach to development with the mobile version offering a simpler and pared down experience to the desktop version of the same site.

The biggest drawbacks to using responsive websites are firstly that the app cannot be distributed through an app store; this can be a deal breaker if you’re looking to monetize downloads of your app. Secondly, there’s the issue that the user will need constant connectivity to make use of the website. This may not be a problem in highly developed markets where mobile broadband is near ubiquitous but can be a serious issue in developing markets.

It’s worth noting that while, at this moment in time, apps appear to be the driving force behind the mobile web – there is room for serious disruption. With the average user already using up to 30 apps a month and with more than 250,000 apps being released a year; there may come a point of overload from a user’s perspective. At that point, it is possible that if there are enough well designed mobile websites – that users will move away from apps and back to browsing and individual sites to provide their online experience. Then, apps might just become “launchers” of mobile websites.

The Take Away

The mobile web offers significant opportunity to entrepreneurs. Mobile apps are relatively cheap and easy to produce. Choosing the right development approach is critical to delivering the right experience. By understanding the differences between hybrid, native and responsive – you can make the right decision for your project.

未将对象引用设置到对象的实例？

关于“未将对象引用设置到对象的实例”这个错误的解决步骤如下：

1、首先，所设置的变量为空值或没有取到值,一般出现在传递参数的时候出现这个问题,也会在使用DataGrid或gridview或datalist等数据控件时出现。

2、设置控件名称与codebehind里面的没有对应。

3、设置未用new初始化对象或者在程序中所引用的控件不存在。

4、然后使用try..catch...finally捕捉错误,或直接用response.write()输出所取的变量值。

5、查看代码中是否存在未初始化的变量，即可解决未将对象引用设置到对象的实例”的问题。

未将对象引用设置到对象的实例怎么解决啊？

"未将对象引用设置到对象的实例"是一种常见的错误，它通常表示在代码中尝试访问一个空对象或未初始化的对象。要解决这个错误，可以采取以下步骤：

1. 检查代码中是否存在空引用或未初始化的对象。查找可能导致错误的代码行，并确认相应的对象已经正确地实例化或赋值。

2. 确保在使用对象之前对其进行初始化。在创建对象之后，确保为其分配内存或设置适当的值。

3. 检查对象引用是否正确传递。如果在代码中涉及多个对象之间的交互，确保将对象正确地传递给需要引用它们的方法或属性。

4. 使用条件语句或空引用检查来避免空引用错误。在访问对象之前，使用条件语句（如if语句）或空引用检查来验证对象是否为null。这样可以避免空引用错误导致的异常。

5. 调试代码以确定引发错误的具体位置。使用调试工具或输出语句来追踪代码的执行路径，找出引发错误的具体位置，并检查相关代码逻辑。

6. 阅读错误信息和堆栈跟踪以获取更多信息。错误信息和堆栈跟踪可以提供有关错误发生的上下文和调用堆栈的信息，帮助您定位和解决问题。

根据具体的编程语言和上下文，解决此错误可能会有所不同。如果您可以提供更多关于错误发生的上下文和相关代码的详细信息，我可以为您提供更具体的帮助。
