screencap, touch, remote control for android devices via adb

Project description

说明

用于android设备远程实时控制的工具整合包。

  • 封装了minicapminicap_sdk32minitouchADBKeyboard 的预编译包
  • 支持多线程(threading)中资源自动分配,但应避免在多进程(multiprocessing)中使用
  • 支持多设备连接
  • 支持安卓设备的实时截图(延迟约30~40ms)
  • 支持修改分辨率
  • 支持监听屏幕旋转
  • 支持监听输入框弹出
  • 内置触控点坐标变换
  • 支持中文输入
  • 包含一个远程控制demo
  • 支持安卓系统版本android<=12, sdk<=32

适用场景

  • 有一定实时性要求的安卓游戏自动控制项目
  • 需要从不同线程控制、获取屏幕内容的多线程项目

安装

pip install anhelper

Demo

运行demo需要确保已经通过adb连接安卓设备

anhelper-demo

已知问题

  • 实体机上可能存在输入设备写入权限问题,导致minitouch无法运行。需要adb获取root权限。
  • 部分机器需要手动在设置中开启ADBKeyboard并且手动切换输入法才可用。

用于安卓控制的同类开源项目推荐

在python项目中使用

Device

from anhelper import device

Minicap

from anhelper import minicap
from anhelper.utils.visualizehelper import *
# 获取默认设备的minicap输入法对象
mcap = minicap.getMinicap()
# 截图默认返回cv2格式BGR矩阵
# sync=True 获取当前时间之后的第一帧
imat = mcap.cap(sync = True)
imshow(imat)

# 对于静态画面minicap不会发送新的帧,所以同步截图设置了1秒超时

Minitouch

from anhelper import minitouch

# 获取默认设备的minicap输入法对象
touch = minitouch.getMinitouch()
%%time
# 由于触控设备通常支持多个触控点,使用useContact()自动分配触控点,以避免冲突
# 所有的触控操作推荐使用比例坐标而非绝对坐标
# 比例坐标:x = 绝对坐标x/屏幕宽度, y=绝对坐标y/屏幕高度, 0 <= x,y <= 1
with touch.useContact() as c:
    c.swipe(0.5,0.2, 0.5, 0.4, duration_ms=3000)
    print(c.id)
    
with touch.useContact() as c:
    print(c.id)
    c.tap(1000, 500)
    c.tap(0.5, 0.5)

# 绝对坐标也可以使用但不推荐,坐标原点为旋转后的屏幕左上角,与截图坐标一致

# 用完记得关
touch.close()

WebUI(Demo)

from anhelper import webui
from IPython.display import IFrame
# 创建一个webui,绑定默认设备(连接的第一个),可以使用不同的device_id来绑定不同设备
# webui可以在网页中同步显示设备屏幕的内容
# divice_id 可以通过 device.listDevices()获取
ui = webui.WebUI(device_id=None)
ui.start()
# 检查webui是否正在运行
ui.is_alive()
True
IFrame( ui.url, width='100%',height='400px')
