问题 Not able to get the right image url when I select the images from the android device, I am able to get the temp image url from the cache where there is no original imaged copied to it. The Url which I got from the plugin looks like this. "file:///data/user/0/com.myapp.dev/cache/tmp_20180118_125700267959888.jpg" Is there any way to get the original image path or the temp url itself where the duplicate image is present in it? Plugin URL : https://github.com/wymsee/cordova-imagePicker.git Plugin

问题 I am having an issue converting the input file object into Base64 in my ionic v2 app . The issue occurs specifically when using the onload/onloadend reader as it gets called only occasionally (rarest of rarest to be very specific).
