Can Uniapp write native code?

Uniapp is a very popular mobile application development framework that allows developers to write code once and run it on multiple platforms at the same time, such as iOS, Android, and Web. Although Uniapp provides powerful cross-platform development capabilities, sometimes we need to write native code to implement more advanced functions, such as using hardware devices or calling operating system APIs.

So, can Uniapp write native code? The answer is yes. Uniapp supports the use of native code through the plug-in mechanism. The following are the specific steps:

Step 1: Add plug-ins

We need to add corresponding plug-ins to the project. Uniapp officially provides some commonly used plug-ins, and we can also write plug-ins ourselves. The following is an example of adding the uni-plugin-camera plug-in:

1. Open the HBuilderX tool, right-click "Project Name"-> "Plug-in Installation"
2. Search for uni-plugin- camera plug-in, click "Install"
3. After installation, introduce the plug-in into the project

Step 2: Call the plug-in

After adding the plug-in, we Plugins can now be called from code. Taking the uni-plugin-camera plug-in as an example, the following code shows how to open the camera and obtain photos:

//Introducing the camera plug-in
import camera from '@/uni_modules/uni-plugin-camera'

// Call the camera
camera.takePhoto({
success: (res) => {

console.log(res.tempImagePath)

},
fail: (err) => {

console.log(err)

}
})

Step 3: Write native code

If the existing plug-ins cannot meet our needs, we can write our own native code and Package it as a plugin. The following is the general process for writing native code:

1. Write native code, such as using Android Studio to write Android native code
2. Package native code as a plug-in
3. Plug-in Introduced into the Uniapp project
4. Developers can call their own plug-ins in the Uniapp project to implement advanced functions using native code.

Summary

Uniapp supports the use of native code through the plug-in mechanism, allowing developers to use native functions while developing across platforms. If the plug-ins provided by Uniapp do not meet your needs, you can also write your own plug-in to use native code. This feature makes Uniapp a powerful cross-platform development framework.
