方案升级包放到APP可以访问的目录手机开热点并启动一个HTTP服务设备连接手机热点另外设备端开启一个 telnet 服务手机通过 telnet 登录到设备系统Android系统热点的默认IP地址是192.168.43.1APP可以遍历192.168.43这个IP段的IP以及固定的端口通过指令下载固件完成升级。
1. 用到的第三方库
implementation commons-net:commons-net:3.9.0 // telnet
implementation org.nanohttpd:nanohttpd:2.3.1 // NanoHttpd
implementation org.apache.commons:commons-compress:1.23.0//解压缩文件
implementation com.github.junrar:junrar:7.5.4//解压rar
implementation org.tukaani:xz:1.9//解压.7z文件需要
implementation com.sparkjava:spark-core:2.9.4// sparkjava
2. 添加权限 uses-permission android:nameandroid.permission.ACCESS_NETWORK_STATE /uses-permission android:nameandroid.permission.INTERNET /uses-permission android:nameandroid.permission.ACCESS_WIFI_STATE /uses-permission android:nameandroid.permission.CHANGE_WIFI_STATE /uses-permission android:nameandroid.permission.CHANGE_NETWORK_STATE /uses-permission android:nameandroid.permission.WRITE_SETTINGS /uses-permission android:nameandroid.permission.ACCESS_COARSE_LOCATION /!-- If your app targets Android 13 (API level 33)or higher, you must declare the NEARBY_WIFI_DEVICES permission. --!-- If your app derives location information fromWi-Fi APIs, dont include the usesPermissionFlagsattribute. --uses-permissionandroid:nameandroid.permission.NEARBY_WIFI_DEVICESandroid:usesPermissionFlagsneverForLocationtools:targetApis /!-- If any feature in your app relies onprecise location information, dont include themaxSdkVersion attribute. --!-- Android12获取SSID需要 ACCESS_FINE_LOCATION 权限 --uses-permissionandroid:nameandroid.permission.ACCESS_FINE_LOCATIONandroid:maxSdkVersion32 /uses-permissionandroid:nameandroid.permission.READ_EXTERNAL_STORAGEandroid:maxSdkVersion32 /
3. 开启热点
APUtil.kt
import android.Manifest
import android.content.ActivityNotFoundException
import android.content.ComponentName
import android.content.Context
import android.content.Intent
import android.content.pm.PackageManager
import android.net.wifi.SoftApConfiguration

}
4. 开启HTTP服务
使用 nanohttpd 实现 HttpFileServer.kt
import android.content.Context
import android.util.Log
import fi.iki.elonen.NanoHTTPD
import org.json.JSONObject
import java.io.FileInputStream
import java.io.FileNotFoundException
import java.io.IOException
import java.util.stream.Collectors/*** 手机开热点时使用的IP*/
const val SERVER_IP 192.168.43.1
const val SERVER_PORT 8080private const val TAG HttpFileServer// HFS
class HttpFileServer(context: Context, ipAddress: String) : NanoHTTPD(ipAddress, SERVER_PORT) {init {rootDir context.getExternalFilesDir(OTA)!!.absolutePathLog.i(TAG, rootDir$rootDir)}override fun serve(session: IHTTPSession): Response? {val params session.parametersLog.e(TAG, String.format(uri%s, session.uri))for (entry in params.entries) {Log.e(TAG, String.format(%s%s, entry.key, entry.value.stream().collect(Collectors.joining(, ))))}return responseFile(session)}private fun responseFile(session: IHTTPSession): Response? {//目前使用的是 http://192.168.43.1:8080/filenameval uri session.urival filename uri.substring(uri.lastIndexOf(/) 1)return try {//文件输入流val fis FileInputStream($rootDir/${filename})newFixedLengthResponse(Response.Status.OK, application/octet-stream, fis, fis.available().toLong())} catch (e: FileNotFoundException) {Log.e(TAG, $filename 文件不存在, e)val jsonObj JSONObject()jsonObj.put(message, $filename 文件不存在)Log.e(TAG, jsonObj.toString(2))newFixedLengthResponse(Response.Status.NOT_FOUND, application/json, jsonObj.toString(2))} catch (e: IOException) {e.printStackTrace()newFixedLengthResponse(session.uri 异常 e)}}companion object {var rootDir: String }
}使用 sparkjava 实现 注意使用的是sparkjava而不是大数据分析的那个Spark
// http://192.168.43.1:8080/download?filenamedog.jpg
Spark.port(8080)
Spark.get(download) { req, res -val filename req.queryParams(filename)println(thread ${Thread.currentThread().id} - $filename)res.status(200)res.header(Content-Type, application/octet-stream)res.header(Content-disposition, attachment; filename$filename)context.assets.open(filename).use { istream -istream.copyTo(res.raw().outputStream)}res
}
5. 使用 telnet
WifiUtil.kt
telnet 主要用到了 WifiUtil 的一个属性network
import android.content.Context
import android.net.ConnectivityManager
import android.net.Network
import android.net.NetworkCapabilities
import android.net.NetworkRequest

}TelnetUtil.kt
import android.net.Network
import org.apache.commons.net.telnet.EchoOptionHandler
import org.apache.commons.net.telnet.SuppressGAOptionHandler
import org.apache.commons.net.telnet.TelnetClient
