Android的PhoneGap的2.2错误COM pressing图像 [英] Android Phonegap 2.2 Error compressing image

问题描述

我正在开发使用PhoneGap的2.2（科尔多瓦-2.2.0.js）的应用程序。我试图捕捉图像。当我preSS上传按钮，相机打开时，我拍摄照片，然后出现两种选择，放弃和保存屏幕。如果我点击保存，应用程序回归到我原来的屏幕，我收到错误的错误COM pressing形象。

I am developing an app using phonegap 2.2 (cordova-2.2.0.js). I'm trying to capture an image. When i press the button for upload, the camera opens, i take the picture, and then a screen appears with two options, discard and save. If i click save , the app return to my original screen and i receive the error Error compressing image.

我以前从PhoneGap的文档的code：

I used the code from the phonegap docs:

http://docs.phonegap.com/en/ 2.2.0 / cordova_camera_camera.md.html＃cameraOptions

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
alert("device ready");

function onSuccess(imageData) {
    var image = document.getElementById('myImage');
    image.src = "data:image/jpeg;base64," + imageData;
}

function onFail(message) {
    alert('Failed because: ' + message);
}
var options = {
        quality : 100,
        destinationType : Camera.DestinationType.DATA_URL,
        sourceType : Camera.PictureSourceType.CAMERA, 
        encodingType: Camera.EncodingType.JPEG,
        saveToPhotoAlbum: true

}
$("#takePicture").click(function(){
    navigator.camera.getPicture(onSuccess, onFail, options); 

})

}

我试着设置destinationType的选择：Camera.DestinationType.FILE_URI，

I tried setting the option of destinationType : Camera.DestinationType.FILE_URI,

和错误修改错误捕获图像和logcat的显示器

and the error changes to Error capturing image and the logcat displays

十二月12日至11日：23：13.965：W / System.err的（2419）：java.io.FileNotFoundException：/mnt/sdcard/Android/data/ro.iss.my.package/cache/.Pic.jpg ：打开失败：ENOENT（没有这样的文件或目录）

在第一种情况下的logcat不显示任何错误。

In the first case the logcat does not show any errors .

推荐答案

您从您的权限列表中缺少WRITE_EXTERNAL_STORAG​​E。没有它，应用程序将无法写入JPG文件。

You are missing WRITE_EXTERNAL_STORAGE from your list of permissions. Without it the app will be unable to write the jpg file.
