Javascript: window.saveAs in android Webview -

-

i using code save client-generated png files:

my_canvas.toblob (function (blob) {window.saveas (blob, my_filename)}, 'image/png')

i'm using these cross-browser compatibility:

  1. javascript canvas blob 2.0.5 sebastian tschan, https://github.com/blueimp/javascript-canvas-to-blob.
  2. filesaver.js eli grey, http://eligrey.com.

works in ie10+, chrome, firefox, chrome android, breaks down in base web view engine in 4.3. since i'm trying lightly use phonegap here , make compatible non-new current devices mobile, need work in android webview 4.3, @ least.

q & a:

q: how break down?

a: sends me non-existent url instead of making image , opening it.

i've had many problems canvas, blobs , old versions of android.

on version have use blobbuilder, on others webkitblobbuilder (on versions blobbuilder there not correctly implemented), canvas.todataurl not present before android 3 , not work correctly before 4.x...

for reasons used canvas2imageplugin android devices , app works in android 2.3.

you can keep code browser testing window.canvas2imageplugin , using if it's found , continue you've been doing if it's not.
