Comparison of Golang technology in Android and iOS mobile development

Go technology can be used to develop Android and iOS mobile applications across platforms, providing an efficient and easy-to-use development method. Android development: Compile applications into native binaries using Go and the Android NDK. iOS development: Use toolchains like Go Mobile to compile Go code into iOS binaries. Performance: The performance of Go applications is comparable to applications written in native languages. Advantages: Cross-platform development is efficient and easy to get started. Disadvantages: Limited ecosystem, long compile time, and more difficult to debug.

Comparison of Go technology in Android and iOS mobile development

Go technology is a general-purpose, compiled language that is increasingly popular in mobile development. It provides cross-platform development capabilities, enabling developers to create mobile apps for Android and iOS with a single code base.

Android Development

In Android development, you can write Android applications using Go and compile them into native binaries using the Android NDK (Native Development Kit). This approach enables similar performance to native Java and Kotlin development.

Practical case: Using Go to write Android applications

Create a simple Android application that displays Hello, World! Message:

package main

import (
    "android/app"
    "os"
)

func main() {
    app.Run(container())
}

func container() *app.Application {
    result, _ := app.NewApplication(func(a *app.Application) {
        a.OnCreate = func(f *app.Activity) {
            f.Finish()
            os.Exit(0)
        }
    })
    return result
}

iOS Development

In iOS development, you can write and compile into iOS binaries using Go. You can use a cross-compilation toolchain, such as Go Mobile, to compile Go code to ARM64 assembly and link to the Objective-C runtime.

Practical case: Writing iOS applications using Go

Create a simple iOS application that displays Hello, World on UILabel! Message:

package main

import (
    "fmt"
    "os"
    "runtime/cgo"

    "github.com/jackc/ios/objc"
    "unsafe"
)

//export AppDelegate
func AppDelegate() *objc.Class {
    return objc.RegisterClass("AppDelegate", objc.Class{})
}

//export applicationDidFinishLaunching:
func applicationDidFinishLaunching(id objc.ID, cmd objc.SEL) unsafe.Pointer {
    os.Exit(0)
    return objc.Nil
}

func main() {
    cgo.Init(cgo.SizeofPtr == 4)
    objc.RunWith(func() {
        objc.RegisterClass("ViewController", objc.Class{
            Methods: []objc.Method{
                {"viewDidLoad", ",", objc.Ptr},
            },
        })
    })
}

Performance comparison

In terms of performance, Android and iOS apps written in Go are highly competitive with apps written in native languages. Since Go is a compiled language, it produces efficient and fast binaries.

Pros and Cons

Pros:

• Cross-platform development: Build apps for Android and iOS using a single code base
• Efficient: compiled language that produces fast and efficient applications
• Simple: easy to learn and use, making it ideal for both beginners and experienced developers

Disadvantages:

• Ecosystem: Limited third-party libraries and tools compared to native development languages ​​
• Compilation time: For large applications, compilation Time Can Be Long
• Debugging: Debugging Go applications can be more challenging than native languages

Conclusion

Go technology provided for Android and iOS mobile development A cross-platform, efficient and easy-to-use option. It helps developers create high-performance mobile applications while minimizing development and maintenance costs.
