Project: Apache Cordova
Issue Type: Bug
Components: Android, Plugin File

FileWriter write method fails on android lollipop versions when no external
sdcard is present.
Simple test case:
{code:javascript}
function fwriteTest(){
console.log("START FILE WRITE!!");
console.log("CDV dataDirectory: " + cordova.file.dataDirectory);
window.resolveLocalFileSystemURL(cordova.file.dataDirectory,
resolveLocalFSUrlWin, resolveLocalFSUrlErr);
}
function resolveLocalFSUrlErr(err){ console.log("resolve FS ERR: -- " +
JSON.stringify(err)); }
function resolveLocalFSUrlWin(dirEntry){
console.log("resolve FS WIN!!");
dirEntry.getFile('fileWriter.txt', { create: true, exclusive:
false }, getFileWin, getFileErr);
}
function getFileErr(err){ console.log("get file ERR: -- " +
JSON.stringify(err)); }
function getFileWin(fileEntry){
console.log("get file WIN!!");
fileEntry.createWriter(
function(writer){
writer.onwrite = function(evt){
console.log("Write to file WIN!!");
alert("ALL GOOD!!");
};
writer.onerror = function(err){
console.log("Write to file FAIL: -- " +
JSON.stringify(err));
}
writer.write("sample text goes hereee");
},
function(err){
console.log("create writer ERR: -- " +
JSON.stringify(err));
}
);
}
//run test!
fwriteTest();
{code}
AndroidManifest.xml contains the following permission, so it's all good here:
{code:xml}<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE" />{code}
I have two android devices, different android versions (4.4.4 and 5.0.2) and I
have 3 android emulators with android 4.4.2, 5.0.1 and 5.1.1.
I tested all environments with and without ext_sdcard (for emulators do not
enter "Size" for Sd card option) and here are my results:

All results are from LogCat console from android-sdk/tools/monitor tool.
I use Crosswalk 12-stable version as my default webview, but I have tested all
this with System-webview too and the problem persists.
As you can see from printed error on write fail - there is a error 6 code and
from what I've read
[here|https://github.com/apache/cordova-plugin-file#list-of-error-codes-and-meanings]
it's a _NO_MODIFICATION_ALLOWED_ERR_ error.
You can also replace _cordova.file.dataDirectory_ with any other path (i have
tried _cacheDirectory_ and _tempDirectory_) or with a _FileSystem_ path like
_LocalFileSystem.PERSISTENT_ (in this case you'll have to modify the
_dirEntry.getFile_ into _dirEntry.root.getFile_ and the
_resolveLocalFileSystemUrl_ with _requestFileSystem_ method and its arguments)
- issue will persist!
Am I missing some configurations/permissions or it's really a bug?
