Migrating Java 1.8 version to Java 17

[FawadAbbas12]

Hello your provided samples are all using java 8 so if i change my project's version to 17 will it work ?

ya can, can upgrade to Java 11 and further to 17 but a few changes. especially the Sample Code\app\src\main\java\com\dji\sdk\sample\demo\lidar\LidarView.kt

remove this //import kotlinx.android.synthetic.main.view_lidar.view.* gradle may have to upgrade higher Sample Code\build.gradle ext.kotlin_version = '1.8.21' and classpath 'com.android.tools.build:gradle:7.4.2' Sample Code\app\build.gradle sourceCompatibility JavaVersion.VERSION_11 and targetCompatibility JavaVersion.VERSION_11 may need to remove this //apply plugin: 'kotlin-android-extensions'
