android - Cordova app doesn't see file changes until it is restarted, but other programs see them -


i'm modifying image in cordova app file plugin, testing on android 5.0.2. write image file location, read back. changes not visible in image! in es file explorer, can see changed image. , if kill cordova app or re-download it, changes visible.

i'm thinking there caching going on, don't know how flush , proceed... or maybe there else going on?

here code using write image:

function writecurrentfile (thecanvas) {        g_currententries[g_entrynum].createwriter (     function createwriterok (filewriter) {          // createwriter() success         filewriter.onwriteend = function (e) {             writelog ("wrote file w/ note: " + g_currententries[g_entrynum].name);          };           filewriter.onerror = function (e) {             writelog ("error writing file w/ note: " + g_currententries[g_entrynum].name + ": " + e);         };         thecanvas.toblob (function (blob) {             filewriter.write (blob);          }, "image/jpeg", 0.95);       },      function createwriterfail (error) {         // createwriter() error         console.log ("error creating file writer: " + error);         alert ("error creating file writer: " + error);     }); }

and here code reads back:

function readback () {     var tempimg = new image();     var pic = cordova.file.externalrootdirectory + g_currententries[g_entrynum].fullpath;      var pichtml;     var source = g_currententries[g_entrynum].fullpath;     tempimg.onload = gotimg;            // sets callback function     tempimg.onerror = imageerror;     tempimg.src=pic;     function gotimg () {         document.body.appendchild (tempimg);     }     function imageerror (){alert ("image error");     } }
