choice for embedded development. Assembler, C, and even Python can be more open in limited memory, low-power CPUs, or other hardware-constrained systems. However, as the average level of the embedded environment grows, this obstruction has gradually disappeared in recent years. The adoption of New Java compiler technology in embedded environment also reduced the resource demand.The outlook of Java embedded

The Android system does not allow a program that uses C/C ++, it requires that Native C/C ++ be embedded through Java code, that is, Native code is used through JNI. Therefore, JNI is very important to Android Developers. How to package the. so file to. APK Let's start with the simplest case. If there is a JNI implemen

For an experienced Java developer who has access to the source code, any program can be viewed as a transparent model in a museum. Tools such as thread dumps (dump), method call tracking, breakpoints, slice (profiling), and so on, let us know what the program is currently doing, what has just been done, and what will be done in the future. However, the situation in the product environment is not so obvious, these tools are generally not available, or

The mobile phone itself is used as a mobile phone terminal, so its computing power, storage capacity is limited. Its main advantage is easy to carry, can be opened at any time, and the phone is always in the connected state. Therefore, network support is very important for mobile applications.Android完全支持JDK本身的TCP，UDP网络通信API，也可以使用ServerSocket,Socket来建立基于TCP/IP协议的网络通信，也可以使用DatagramSocket,Datagrampacket来建立基于UDP协议的网络通信。Android也支持JDK提供的URL，URLConnection等网络
