1.首先把我们的手机连接到电脑上。

2.在命令行里cd到我们的sdk下的 platform-tools的路径找到我们的adb命令输入 ,输入adb devices查看我们连接的设备

3.使用adb tcpip 8888 设置端口号，5555为默认端口号，也可以设置其它端口号，端口号为需要为4位数

4.拔掉我们的设备，开始无线连接 adb connect
使用adb connect 192.168.1.65:8888， 192.168.1.65为我们手机的ip地址， 其中8888是我们自己设的端口号，这个端口号要和adb tcpip 设置的端口号保持一样，如果我们没有自己设置端口号，直接adb connect192.168.1.65就行了，默认使用5555。 连接成功提示

取消连接就是 adb disconnect
adb disconnect 192.168.1.65:8888

According to the latest news from Huawei's official website, the compiler tool Ark compiler has been released. According to reports, the Ark compiler is a cross-compiler suite developed by GCC. It includes front-ends for C, C++, and Fortran, as well as libraries for these languages (such as libstdc++, libgcc, etc.). HCC runs on an X86 linux architecture server and the generated binary runs on the Aarch64 architecture server.

Preparation before installation

1) Environmental requirements

The Ark compiler supports the following 64-bit operating systems.

SUSE12sp4 and above.

Ubuntu 16.04 and above.

Other glibc versions are available in Linux distributions 2.22 and above.

2) Get the package

Installing the Ark compiler requires an open source package as shown in Table 2-1.

　　GCC 7.3.0 编译器源码包 　https://ftp.gnu.org/gnu/gcc/gcc-7.3.0/gcc-7.3.0.tar.gz
　　Binutils 2.31.1 汇编器、链接器等二进制工具集源码包 　https://ftp.gnu.org/gnu/binutils/binutils-2.31.1.tar.gz
　　Glibc 2.29 GNU libc 库源码包 https://git.linaro.org/toolchain/glibc.git/snapshot/glibc-2.29.tar.gz
　　Mpc 1.1.0 复数运算库 　https://ftp.gnu.org/gnu/mpc/mpc-1.1.0.tar.gz
　　GNU MPFR 4.0.2 多精度浮点计算库 　https://www.mpfr.org/mpfr-current/mpfr-4.0.2.tar.gz
　　isl 0.21 集和线性约束范围内整数点关系的操作库 　http://isl.gforge.inria.fr/isl-0.21.tar.gz

Install the HCC compiler

1) Operation steps

You can use the HCC tarball to install HCC anywhere under the current user privilege without affecting the use of other compilers.

a) Introduce the operation portal, for example, log in to the XX environment with the XX account.

b) Login HCC download address to download the compressed package

Hcc_arm64le.tar.gz

c) Copy the tarball to the directory you want to install.

The command script is as follows.

Cp hcc_arm64le.tar.gz /path/to/your/dir

d) Unzip the package.

The command script is as follows.

Tar zxvf hcc_arm64le.tar.gz

e) Set environment variables.

The environment variable command script is set as shown below.

Export PATH=/path/to/your/dir/hcc_arm64le/bin:$PATH

The build tools provided by the HCC compiler are in the =/path/to/your/dir/hcc_arm64le/bin directory.

2) Check after installation

After the HCC compiler is installed, you can run the aarch64-linux-gnu-gcc -v command to query the HCC version.

According to Huawei's official introduction, the Ark compiler is the first static compiler to completely replace the language virtual machine, completely without an interpreter. A compiler that takes into account Java development efficiency and C language runtime efficiency. Compared to the existing compilation mechanism:

1. The Ark compiler is a static compilation method. In the existing Android system, running an application first starts the virtual machine, then reads the application code and interprets the execution one by one. It will occupy more processing resources and affect the efficiency of program execution. Of course, there are also early or runtime compilation techniques, such as AOT or JIT, that convert some of the programs into machine code and execute them directly on the CPU. However, it is still not possible to do 100% to get rid of virtual machine execution, which is the key to the current Android camp is not as good as the IOS camp.
2. The static compilation mode of the Huawei Ark compiler can directly translate the dynamic features in the language into machine code. After the application is installed, the mobile phone can run the program at full speed, completely eliminating the drawbacks of the virtual machine and bringing about great improvement in efficiency.
3. The Ark compiler is a compiler deployed in the development environment, and the existing compilation process mainly occurs on the mobile phone, which brings additional resource consumption.

At present, the Ark compiler is compiled and optimized for the general-purpose ARM chip architecture. In the future, the capabilities of the Kirin chip will be maximized through software and hardware co-design. At the same time, the Ark compiler supports Java standard usage, and the three-party application can be compiled directly without modifying the code. But if you want to get better performance or memory improvements, you can adjust the code structure and optimize with the Ark compiler.

如果您在编写HTML5应用，需要在JS代码中访问Java中的函数，则您会用到WebView的addJavascriptInterface()函数。因为安全问题，在Android4.2中(如果应用的android:targetSdkVersion数值为17+)JS只能访问带有 @JavascriptInterface注解的Java函数。
之前，任何Public的函数都可以在JS代码中访问，而Java对象继承关系会导致很多Public的函数都可以在JS中访问，其中一个重要的函数就是 getClass()。然后JS可以通过反射来访问其他一些内容。通过引入 @JavascriptInterface注解，则在JS中只能访问 @JavascriptInterface注解的函数。这样就可以增强安全性。
如果您的应用android:targetSdkVersion数值为17或者大于17记得添加 @JavascriptInterface 注解。

js中调用 java中的clickedAgreement方法
CourseInfo.clickedAgreement(paramData.i,paramData.j,1);
