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 + ")");
}
