android - Phonegap Build: download image in one of the folders of your app -

i able download image if specify path straight

file:///storage/sdcard0/

how can save image 1 of folders in app ? tried this approach set app path doesn't work me.

this using far , works if want save , image sdcard:

class="lang-js prettyprint-override">var filename = "myimage.png"; var filetransfer = new filetransfer(); var uri = encodeuri("http://my.url.to.image/myimage.png"); var filepath = "file:///storage/sdcard0/uploads/myimage.png"; filetransfer.download( uri, filepath, function(entry) { alert("download complete: " + entry.fullpath); console.log("download complete: " + entry.fullpath); }, function(error) { alert("download error source/target/code:\n" + error.source +" \n||| "+error.target+" \n||| "+error.code); console.log("download error source/target/code " + error.source+" / "+error.target+" / "+error.code); } );

if utilize function:

function getphonegappath() { 'use strict'; var path = window.location.pathname; var phonegappath = path.substring(0, path.lastindexof('/') + 1); homecoming phonegappath; }

i /android_asset/www/. how right path app?

the app using angularjs , not bootstrapped in ondeviceready (developer before me made way , changing this beyond me (tried didn't work)).

another question can refer asked here. tried this, this, this , this none worked me. "" fullpath , managed path printed .tourl() , "cdvfile://localhost/persistent". the above download code works if use

filepath = "cdvfile://localhost/persistent/myappid/uploads/myimage.png";

but creates folder /myappid/uploads in /storage/sdcard0 bad again. app needs images

<img src="uploads/myimage.png" alt="myimg"/>

another useful link here offers no help how write pre-created folder of own app.

edit: far i've learned cannot write within own app(read only). that's why tried reference images sdcard

<img src="file:///storage/sdcard0/android/data/com.app.my/cache/myimage.png" alt="myimg"/>

and works! :) unfortunately hardcoded , not since other phones might have different persistent location. if seek

<img src="cdvfile://localhost/persistent/android/data/com.app.my/cache/myimage.png" alt="myimg"/>

this not reference image :/ (it download on storage/sdcard0/android/data/com.app.my/cache/ though)

as far learned cannot write own app (change items within app - /www folder on android).

my solution save images persistent storage (sdcard usually). can path of app's persistent storage these steps:

function ondeviceready() { console.log('device platform: ' + device.platform); // returns 'android' or 'ios' instance window.requestfilesystem(localfilesystem.persistent, 0, gotfs, fail); cachefoldersubpath = "android/data/com.id.myapp/cache/"; // app's cache folder removed when delete app! (i don't know path should ios devices) }

then within gotfs success callback

function gotfs(filesystem) { var nturl = filesystem.root.tonativeurl(); // cdvfile://localhost/persistent/ window.resolvelocalfilesystemurl(nturl+cachefoldersubpath, onresolvesuccess, onresolvefail); }

and in onresolvesuccess

function onresolvesuccess(fileentry){ appcachepath = fileentry.tonativeurl()+"/"; // file:///storage/sdcard0/android/data/com.id.myapp/cache/ in case other androids have storage/emulated/0 or ... continuecustomexecution(); }

and in continuecustomexecution() can run programme , whatever ... , in case download images appcachepath got earlier. can reference images in src tags our appcachepath+yourimagename.

unfortunately still don't know how download image on ios. error code 1 filetransfer plugin ... (saving file:///var/mobile/applications/my.app.id/documents/). should save somewhere else path when requesting persistent filesystem.

cheers
