Problems should be noticed in the development of mobile video conferencing software

With the rapid development of mobile Internet, the annual growth of smartphones is much larger than that of PC, and the corresponding types of mobile terminals and the number of software are increasing rapidly, so most PC application software can find similar software on mobile terminals, and even many of the company's PC software are ported to mobile terminals. The mobile terminal software has been able to be equal to PC software. As an enterprise-class high-end application-video conferencing software, as with most software, in the mobile terminal has a corresponding application software. Video conferencing on mobile phones, tablets, and even on smart TVs is no longer a novelty. So how can we develop a video conferencing software like PC on a mobile terminal? What questions should we pay attention to?

First we want to classify the mobile terminal, now mobile terminals generally include mobile phones, tablet computers. Different phones, tablets may use the same operating system, the operating system is general and development is very close. and the terminal operating system is divided into Android, IOS, WP, Symbian and so on. Today's mainstream mobile terminal operating system is mainly Android and iOS two camps. Android operating system is based on the C-developed Linux kernel operating system, its openness is better, anyone can modify their own Android operating system, so this approach has been supported by many mobile phone manufacturers. While the iOS operating system is relatively closed to Android, its code is mainly changed from the UNIX code, the operating system only provides interfaces, cannot modify the operating system. After learning about the mobile operating system, we came up with a comparison of the development of Android and iOS applications, although Android is a C-based Linux operating system, but it provides a virtual machine, the upper layer of the virtual machine is composed of Java, Therefore, the development of Android applications can be directly used in the familiar Java development, of course, we can also use the JNI way to call the underlying C function, through the JNI way, we can get higher processing performance, so in the development of video conferencing software, Some computationally significant operations are best implemented using JNI calls to the underlying C voice. The iOS operating system's development voice is Object C, its language is basically close to the C + + language, its execution is more efficient, so when we use the mobile phone, we will find that the iOS operating system more fluent than Android. Another feature of Object C is that it is close to the C language and can even embed the C language, so it is easy for some C-language programmers to use the object C language. When we develop video conferencing software for iOS, it can also be implemented by embedding the C language, because the Video conferencing system is generally C + +, which translates to an object C is not a difficult thing.

Another question is what development tools do we choose in the development of mobile video conferencing software, and what development tools or environments do we choose on the Android and iOS operating systems? Is there a unified development environment? In my opinion, two operating systems are too different, there is no need to use the same development environment, some development tools claim to support both Android and iOS, but these development tools are generally very limited, the use of tools are very limited. On Android, we recommend using the Eclipse development environment, which is no longer familiar to Java developers, who can easily master the development of Android. The development environment of iOS is only Xcode, its development environment is very powerful, Xcode can all put all the tools in the same development environment, at this point Xcode is more reasonable than eclipse. In the development of mobile video conferencing software, we will be on the Android system to do JNI operations, and the JNI operation is not supported on eclipse, we have to use the command line approach, so the development of video conferencing software on iOS, more efficient than Android.

In the end, the development of our mobile video conferencing software, mainly on Android and iOS system, its development language is Java, C and Object C, in the development of tools, we prefer eclipse in Android, and on iOS, we use Xcode.
