javascript - Retrieving and displaying photo with phonegap works in emulator but not on my phone -

i using phongap api take photo , display in app. works fine in emulator (using ripple extension in chrome) doesn't work on phone or tablet (both android). got ideas why?

edit: i've established taking , returning photo ok, , creating canvas, not drawing image canvas reason.

edit 2: resolved after reading this: how can load image onto html5 canvas using phonegap. later features not working . . . in case looks problem wasn't permissions.

// called 'take photo' button function takephoto() {   // take picture using device camera , retrieve image base64-encoded string. if         //camera unavailable offer option retrieve file   navigator.camera.getpicture(onsuccess, onfail, { quality: 50,   destinationtype: camera.destinationtype.data_url } ); }   // displays image on screen    function onsuccess (imagedata) {     alert("hello " + imagedata.length); //added check if making      ///this point      var image = document.getelementbyid("image");     image.src = imagedata;     var c=document.getelementbyid("mycanvas");     var ctx=c.getcontext("2d");             ctx.drawimage(image,0,0,c.width,c.height);         }   function onfail(message) {   alert("failed because: " + message); }
