Android project has no code suggestions

In Android project how can I get android code suggestions?

OS: windows 10 Gradle: 6.5 JDK: installed 8, 11 ,17 IDE: Neovim 0.10.1

I set JAVA_HOME and ANDROID_HOME in the system variables, but after building the project and install dependences, no errors, I only get basic JDK code suggestions and no Android code suggestions. Do I need to make any special settings in my lua file, or is there any other configuration needed? I'm a newbie in this area and would appreciate any help! Thanks!

my config

config = {
        -- set jdtls server settings
        jdtls = {
          function()
            -- use this function notation to build some variables
            local root_markers = { ".git", "mvnw", "gradlew", "pom.xml", "build.gradle" }
            local root_dir = require("jdtls.setup").find_root(root_markers)
            -- calculate workspace dir
            local project_name = vim.fn.fnamemodify(vim.fn.getcwd(), ":p:h:t")
            local workspace_dir = vim.fn.stdpath "data" .. "/site/java/workspace-root/" .. project_name
            os.execute("mkdir " .. workspace_dir)
            -- get the mason install path
            local install_path = require("mason-registry").get_package("jdtls"):get_install_path()
            -- get the current OS
            local os
            if vim.fn.has "macunix" then
              os = "mac"
            elseif vim.fn.has "win32" then
              os = "win"
            else
              os = "linux"
            end
            -- return the server config
            return {
              cmd = {
                "java",
                "-Declipse.application=org.eclipse.jdt.ls.core.id1",
