LED&相机总是开启 [英] LED & Camera always ON

问题描述

我正在尝试打开设备相机，立即激活该设备的LED灯（Android / iOS）。

我试过了appcelerator ti。媒体事件，但没有工作，这个模块： Ti.Light 。

在此链接上找到此信息 activate-iphone-4-led-light

对于flash的东西，你必须检查属性：
Ti.Media.cameraFlashMode（区分大小写）

要更改它，你可以使用Ti。 Media.setCameraFlashMode（PARAM）。

PARAM可以是：Ti.Media.CAMERA_FLASH_OFF，Ti.Media.CAMERA_FLASH_ON，
Ti.Media.CAMERA_FLASH_AUTO

不幸的是，你不能启动led并将其用作火炬，你可以
只控制相机闪光灯处理（开，关，自动），而采取
照片。

有任何模块允许使用LED灯吗？

UPDATE 1＃： >我正在尝试使用您的ts.camera小部件，其中包含embed相机和flash方法：

• github - ts.camera


• gittio - ts.camera

但是在pw.custom.androidcamera模块中没有方法switchFlashlight（），此小部件工作？

• github - Ti-Android-CameraView


• gittio - pw.custom.androidcamera

UPDATE 2＃：

为了找到工作流程，我添加了这个手电筒模块，

这是我的index.js文件：

p>

  if（OS_ANDROID）{
 
 flash = require（'dk.napp.flashlight'）; 
 
 if（！flash.isFlashLightOn（））flash.turnFlashLightOn（）; 
 
 camera = require（'pw.custom.androidcamera'）; 
 
 view = camera.createCameraView（）; 
} 
  

我收到此错误：

  [DEBUG]：CameraViewProxy：相机不可用
 [错误]：CameraViewProxy：相机为空。确保
 [错误]：CameraViewProxy：< uses-permission android：name =android.permission.CAMERA/> 
 [错误]：CameraViewProxy：在您的tiapp.xml文件中。 
  

这是我的tiapp.xml文件：

 < uses-permission android：name =android.permission.CAMERA/> 
< uses-permission android：name =android.permission.FLASHLIGHT/> 
< uses-feature android：name =android.hardware/> 
< uses-feature android：name =android.hardware.camera/> 
< uses-feature android：name =android.hardware.camera2/> 
< uses-feature android：name =android.hardware.camera2.params/> 
< uses-feature android：name =android.hardware.camera.flash/> 
< uses-feature android：name =android.hardware.camera.autofocus/> 
  

解决方案

这两个模块可以完成这项工作：

虽然很可能是启用装置相机会取代对闪光灯的控制。

I'm trying to open the device camera an activate immediately the LED light of that device (android/iOS).

I've tried the appcelerator ti.media events but didn't work, neither this module: Ti.Light.

Found this on this link activate-iphone-4-led-light

Hey guys!

For the flash stuff you have to check the property: Ti.Media.cameraFlashMode (case sensitive)

To change it you can use Ti.Media.setCameraFlashMode(PARAM) .

PARAM could be: Ti.Media.CAMERA_FLASH_OFF , Ti.Media.CAMERA_FLASH_ON, Ti.Media.CAMERA_FLASH_AUTO

Unfortunately you can’t start the led and use it as a torch, you can only control the camera flash handling (on, off, auto) while taking a photo.

There is any module that allow to use the led light all the time? I just need this while the camera is opened.

UPDATE 1#:

I’m trying to use your ts.camera widget, that have the embed camera and flash methods:

• github - ts.camera
• gittio - ts.camera

But there is no method switchFlashlight() in "pw.custom.androidcamera" module, this widget works?

• github - Ti-Android-CameraView
• gittio - pw.custom.androidcamera

UPDATE 2#:

In order to find a workaroud, I've added this flashlight module, and I'm trying to call it before or after showing the camera, but I think that it's not possible to have 2 camera activities at the same time.

This is my index.js file:

if(OS_ANDROID) {

    flash = require('dk.napp.flashlight');

    if(!flash.isFlashLightOn()) flash.turnFlashLightOn();

    camera = require('pw.custom.androidcamera');

    view = camera.createCameraView();
}

I'm getting this error:

[DEBUG] :  CameraViewProxy: Camera not available
[ERROR] :  CameraViewProxy: Camera is null. Make sure
[ERROR] :  CameraViewProxy:     <uses-permission android:name="android.permission.CAMERA" />
[ERROR] :  CameraViewProxy: is in you tiapp.xml file.

This is my tiapp.xml file:

<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.FLASHLIGHT"/>
<uses-feature android:name="android.hardware"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera2"/>
<uses-feature android:name="android.hardware.camera2.params"/>
<uses-feature android:name="android.hardware.camera.flash"/>
<uses-feature android:name="android.hardware.camera.autofocus"/>

解决方案

These two modules might do the job:

Although it could well be that activating the device camera will override the control over the flash light.
