检索数据时的PhoneGap相机故障 [英] Phonegap camera failure when retrieving data

问题描述

---------------更新---------------

似乎there's某种与HTC Desire的摄像头的问题，这个版本的PhoneGap的。这个问题似乎是HTC返回Android上的摄像头规格的方式。

Seems that there´s some kind of problem with HTC Desire camera and this version of Phonegap. The issue seems to be the way HTC returns the camera specs on Android.

从来就一直在使用PhoneGap的重写我的previous应用程序的code，但不是我需要使用相机API。当我用它真正的手机上坠毁拍照后，我得到这个错误与SendLog。

I´ve been using phonegap to rewrite the code of my previous application but not I need to use the camera API. When I used it on a real phone it crashed after taking the photo and i got this error with SendLog.

有谁知道为什么会这样？

Does anyone know why this happens?

这是我的Camera.js

This is my Camera.js

这是我的Camera.js

This is my Camera.js

var options = { quality : 75, 
      destinationType : Camera.DestinationType.DATA_URL, 
      sourceType : Camera.PictureSourceType.CAMERA, 
      allowEdit : true,
      targetWidth: 100,
      targetHeight: 100 };

function capturePhoto() {
    // Take picture using device camera and retrieve image as base64-encoded string
    navigator.camera.getPicture(onPhotoDataSuccess, onFail, options);
}

function onPhotoDataSuccess() {
    // Uncomment to view the base64 encoded image data
    var theHTML = '';
    theHTML = '<div id="info">CameraSuccess</div>';
    document.getElementById('main').innerHTML = theHTML;
}

function onFail(message) {
    // Called if something bad happens. 
    alert('Failed because: ' + message);
}

希望它能帮助

这code正常工作对我来说，我已经得到了只有.js文件提到关于该指数code和一个按钮与capturePhoto（）函数。

This code works fine for me, I've got only the .js reference to this code on the index and a button with the capturePhoto() function.

希望它可以帮助任何人解决他们的问题。

Hope it helps to anyone fix their problems.

var pictureSource;   // picture source
var destinationType; // sets the format of returned value 

// Wait for PhoneGap to connect with the device
//
document.addEventListener("deviceready",onDeviceReady,false);

// PhoneGap is ready to be used!
//
function onDeviceReady() {
    pictureSource=navigator.camera.PictureSourceType;
    destinationType=navigator.camera.DestinationType;
}

// Called when a photo is successfully retrieved
//
function onPhotoDataSuccess(imageData) {
  // Uncomment to view the base64 encoded image data
  // console.log(imageData);

  // Get image handle
  //
  var smallImage = document.getElementById('smallImage');

  // Unhide image elements
  //
  smallImage.style.display = 'block';

  // Show the captured photo
  // The inline CSS rules are used to resize the image
  //
  smallImage.src = "data:image/jpeg;base64," + imageData;
}

// Called when a photo is successfully retrieved
//
function onPhotoURISuccess(imageURI) {
  // Uncomment to view the image file URI 
  // console.log(imageURI);

  // Get image handle
  //
  var largeImage = document.getElementById('largeImage');

  // Unhide image elements
  //
  largeImage.style.display = 'block';

  // Show the captured photo
  // The inline CSS rules are used to resize the image
  //
  largeImage.src = imageURI;
}

// A button will call this function
//
function capturePhoto() {
  // Take picture using device camera and retrieve image as base64-encoded string
  navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50 });
}

// A button will call this function
//
function capturePhotoEdit() {
  // Take picture using device camera, allow edit, and retrieve image as base64-encoded string  
  navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true }); 
}

// A button will call this function
//
function getPhoto(source) {
  // Retrieve image file location from specified source
  navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50, 
    destinationType: destinationType.FILE_URI,
    sourceType: source });
}

// Called if something bad happens.
// 
function onFail(message) {
  alert('Failed because: ' + message);
}
