我目前正想在相机关闭后直接拍摄照片,将照片添加为HTML图像的来源。但我不断收到以下错误:

09-09 19:16:08.585: D/DroidGap(10719): Resuming the App
现在我使用的是Android 4.0.3和Cordova 2.3.0。我目前有以下代码:
HTML
<button onclick="capturePhoto();">Take Photo</button>
<img id="cameraPic" src="" style="width:auto;height:120px;"></img>
的JavaScript
var pictureSource;
var destinationType;
function onDeviceReady() {
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
function capturePhoto(){
navigator.camera.getPicture(uploadPhoto,null,{ quality: 20, allowEdit: true,
destinationType: destinationType.DATA_URL });
};
function uploadPhoto(data){
// this is where you would send the image file to server
//output image to screen
$("#cameraPic").src = "data:image/jpeg;base64," + data;
}
我真的不确定为什么我会收到这个错误。任何帮助都会非常感激。
在我的config.xml文件中,我拥有以下权限:
<plugin name="Camera" value="org.apache.cordova.CameraLauncher"/>
在我的Android清单中,我有:
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

尝试使用以下代码。我猜你没有使用PhoneGap事件监听器调用onDeviceReady函数。
var pictureSource; // picture source
var destinationType; // sets the format of returned value
document.addEventListener("deviceready",onDeviceReady,false);
function onDeviceReady() {
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
function capturePhoto() {
navigator.camera.getPicture(uploadPhoto, uploadFail, { quality: 20, allowEdit: true,
destinationType: destinationType.DATA_URL });
}
function uploadPhoto(data){
$("#cameraPic").src = "data:image/jpeg;base64," + data;
}
function uploadFail(error) {
alert('Failed because: ' + error);
}

检查目的地类型。
navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.DATA_URL // check this line and replace it...
});
function onSuccess(imageData) {
var image = document.getElementById('myImage');
image.src = "data:image/jpeg;base64," + imageData;
}
function onFail(message) {
alert('Failed because: ' + message);
}
