WebView caching resized pictures
--------------------------------

                 Key: CB-17
                 URL: https://issues.apache.org/jira/browse/CB-17
             Project: Apache Callback
          Issue Type: Bug
          Components: Android
    Affects Versions: 1.1.0
            Reporter: Simon MacDonald
            Assignee: Simon MacDonald


If you request a picture from the photo library and you provide a targetHeight/targetWidth
we create a temp file in the application cache directory called resize.jpg. If you then show
this file in your PG application it works fine. Any subsequent calls to getPhoto using targetHeight/targetWidth
will create a new resize.jpg but when you go to display it in your app it shows the first
one as it is cached.

Workaround: If your picture is small enough use DATA_URL

Here is some code to reproduce:

function getPhoto(source) {
   sourceType=source;
       window.resolveLocalFileSystemURI("file:///mnt/sdcard/Android/data/
com.phonegap.helloworld/cache/resize.jpg", fileExist, onFail);
}
  //,allowEdit: true,targetWidth:390,targetHeight:390

function fileExist(fileEntry) {
               alert(fileEntry.fullPath);
       fileEntry.remove(removeSuccess,removeFail);
}

function onFail(error) {
        navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality:
75,
             destinationType: destinationType.FILE_URI,
             sourceType: sourceType,targetWidth:390,targetHeight:390});
}

function removeSuccess() {
       alert("file Success Removed");
        navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality:
75,
             destinationType: destinationType.FILE_URI,
             sourceType: sourceType,targetWidth:390,targetHeight:390});
}
function removeFail(error) {
       status("Image file delete failed (error " + error.code + ")");
}
