Connect android to android with wifi

Connect two android phones with wi-fi (without laptop or access point) and send file

Is it possible to connect two android phones by wi-fi, without using a bluetooth/GSM/CDMA/IR? Also, there is no any laptop or wi-fi access points or wi-fi routers. I think, that it is possible to create some SSID on both phones, do a static configure of IP addresses. Will android connect to another’s android wi-fi? If they will be connected, how can I send a file from one phone to second? Is there a ftp-client and server? or Can I ssh to other phone? Or telnel/netcat? Maybe http ?

This is called ad hoc network and has been asked before:

Short answer: ad hoc is not yet supported on Android so this would not work.

You can use Bluetooth to connect two Android phones in a p2p fashion.

Direct device-to-device connection over Wifi is supported under API 14 in Android 4.0 ICS in package android.net.wifi.p2p. You can test devices capability via FEATURE_WIFI_DIRECT.

Thanks! Can you comment the second part of Q — about how to send file after the ad-hoc is configured?

Bluetooth is too slow and short. Ad hoc is not supported in gui, but I can do it by hand (with editing config files on j-b-ed phone)

Of course jailbreaked Android phone is basically a linux device so it can do many things. But you can not write an app that does this. And it probably needs root access too.

@PeterKnego after connecting to the adhoc network created on my laptop is it possible to send data to a udp server running on the laptop? just asking for the guidlines.

This is actually possible with SDK V 14. As the documents state:

1. Create a broadcast receiver for Wi-Fi Direct Intents
2. Set up permissions
3. Set up the receiver in onCreate()
4. Set up an intent filter
5. Register the receiver in onResume()

I’ve included some of the key code constructs below to make this happen. But read the documentation for more information.

Here’s a sample Broadcast Receiver

public class WiFiDirectBroadcastReceiver extends BroadcastReceiver < private WifiP2pManager manager; private Channel channel; private MyWiFiActivity activity; public WiFiDirectBroadcastReceiver(WifiP2pManager manager, Channel channel, MyWifiActivity activity) < super(); this.manager = manager; this.channel = channel; this.activity = activity; >@Override public void onReceive(Context context, Intent intent) < String action = intent.getAction(); if (WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION.equals(action)) < int state = intent.getIntExtra(WifiP2pManager.EXTRA_WIFI_STATE, -1); if (state == WifiP2pManager.WIFI_P2P_STATE_ENABLED) < // Wifi Direct is enabled >else < // Wi-Fi Direct is not enabled >> else if (WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) < // Call WifiP2pManager.requestPeers() to get a list of current peers >else if (WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION.equals(action)) < // Respond to new connection or disconnections >else if (WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION.equals(action)) < // Respond to this device's wifi state changing >> >

Как управлять Android смартфоном по Wi-Fi?

Как управлять телефоном с другого устройства Android по Wi-Fi? Я расскажу про пульт управления, команды ADB, удаление и установку системных приложений. Все инструкции даны для Android 11/12/13, поскольку там есть отладка по Wi-Fi.

Сопряжение по Wi-Fi двух смартфонов

Шаг 1. На смартфоне, к которому будем подключаться, включите “Отладку по Wi-Fi” (смотрите меню для Разработчиков).

Шаг 2. Выбираем опцию “Подключить устройство с помощью кода подключения”.

Шаг 3. На главном смартфоне (с которого будем управлять) ставим приложение “ADB Shell – Debug Toolbox” и запускаем.

Далее выбираем “Сопряжение” и указываем код, IP-адрес и номер порта (эти данные смотрим на втором телефоне).

В поле “Enter pairing code” вводим код подключения. Сопряжение завершено.

Не забываем, что для сопряжения оба устройства должны быть подключены к одной сети (к одному роутеру). А при каждом новом подключении может быть разный IP-адрес и номер порта.

Шаг 4. В командной строке приложения ADB вводим adb devices и смотрим, какие устройства подключены.

Отключаем оно устройство (сам смартфон, с которого будем управлять), чтобы не было путаницы: adb disconnect 192.168.50.80:42961.

В итоге у нас остался сопряженным только второй смартфон, которым мы и будем управлять.

Шаг 5. И далее через терминал вы сможете, например, удалять системные приложения. Используйте команду: pm uninstall -k –user 0 имя пакета.

Управление вторым смартфоном

Шаг 1. Давайте посмотрим, какие приложения установлены на втором смартфоне. В приложении ADB выбираем пункт “Панель инструментов” и наш сопряженный смартфон.

Далее переходим на вкладку “Программы”. Здесь можно запустить, остановить, удалить ТОЛЬКО сторонние приложения! Для удаления системных приложений (предустановленных) используем Терминал (командную строку) и команду – pm uninstall -k –user 0 имя пакета.

Вкладка “Запущенные приложения”. Можно остановить, запустить или удалить приложение.

Вкладка “Скриншот” – можно сделать скриншот экрана второго смартфона.

Вкладка “Локальные файлы” – доступ к папкам и файлам, их удаление. Отсюда можно перекидывать приложения со второго смартфона на главный, с которому мы и управляем.

Вкладка “Файлы на устройстве”– доступ ко всем файлам на втором смартфоне. Их можно архивировать, устанавливать APK-файлы, удалять.

Вкладка “Пульт ДУ” – позволит управлять по Wi-Fi вторым устройством.

Работает навигация по устройству, громкость, меню.

Вкладка “Функции“. Здесь команды управления устройством – перезагрузка, включение/выключение, меню recovery, передача мобильных данных (вкл/откл), включить и отключить экран.

Вкладка “Системный монитор” – показывает использование оперативной памяти и мощности процессора.

Вот так можно управлять вторым устройством на Android через Wi-Fi.
