使用Camera Plugin拍摄新照片时,PhoneGap App崩溃

Question

我正在开发一个带有cordova/phonegap的移动应用程序,我已经安装了Camera插件.我可以打开相机并单击图像,但在该应用程序崩溃后.这是崩溃日志:

    java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=34, result=-1, data=null} to activity {com.phonegap.helloworld/com.phonegap.helloworld.CordovaApp}: java.lang.IllegalArgumentException: filename cannot be null

我用来打开相机的代码是:

   var pictureSource; // picture source
var destinationType; // sets the format of returned value
document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
  // alert("ready-----")
  pictureSource = navigator.camera.PictureSourceType;
  destinationType = navigator.camera.DestinationType;
}

function capturePhoto() {
  alert(navigator.camera);
  navigator.camera.getPicture(onPhotoDataSuccess, onFail, {
    quality: 20,
    destinationType: destinationType.FILE_URI,
    targetWidth: 200,
    targetHeight: 200,
    saveToPhotoAlbum: true,
    sourceType: pictureSource.CAMERA
  });
}

function onPhotoDataSuccess(imageURI) {
  // alert("success--");
  var smallImage = document.getElementById('smallImage');
  smallImage.style.display = 'block';
  smallImage.src = imageURI;
  // smallImage.src = "data:image/jpeg;base64," + imageData;
}

function onFail(message) {
  alert('Failed because: ' + message);
}

该错误已经记录在Apache Cordova中.

救命!!!

请更改您的目的地类型：

destinationType: destinationType.FILE_URI

到

destinationType: Camera.DestinationType.FILE_URI

如果您需要将其作为 Base64 编码图像，请将目标类型更改为：

destinationType: Camera.DestinationType.DATA_URL

还要确保您已在清单文件中添加了写入外部存储权限。
