下載套件

開啟 settings.gradle.kts，在 dependencyResolutionManagement 新增 jitpack  下載庫，如下藍色設定

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven("https://jitpack.io")
    }
}

開啟 build.gradle.kts(Module)，新增藍色部份

android{
    ..............
    buildFeatures{
        dataBinding = true
        viewBinding = true
    }
}

dependencies {
    ............
    implementation ("com.github.pedroSG94.RootEncoder:library:2.5.1")
    implementation ("com.github.pedroSG94.RootEncoder:extra-sources:2.5.1")
}

權限

AndroidManifest.xml 新增藍色權限設定

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-feature android:name="android.hardware.camera.any" />

    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
    <application
        .........

Layout

RootEncoder 使用 Android 系統預設的 SurfaceView 來顯示影片，但如果直接在 Layout 置入 SurfaceView 會有問題。所以請在 Layout 中置入 LinearLayout，到了後面才由程式碼把 SurfaceView 加入 LinearLayout 中。

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <LinearLayout
        android:background="#000000"

        android:onClick="btnPicture_click"/>

</androidx.constraintlayout.widget.ConstraintLayout>

baseline_camera_24.xml

上述的 baseline_camera_24.xml 的代碼如下

MainActivity.kt

MainActivity.kt 先開啟權限，完整代碼如下

package net.ddns.mahaljsp.travelc
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import net.ddns.mahaljsp.travelc.databinding.ActivityMainBinding

class MainActivity : AppCompatActivity() {
    lateinit var permission:MainPermission

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        //enableEdgeToEdge()
        ui= ActivityMainBinding.inflate(layoutInflater)
        setContentView(ui.root)
        permission= MainPermission(this)
    }
    fun init(){
        //todo
    }
    override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<String>,
        grantResults:IntArray){
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        permission.result(this, requestCode)
    }
