+
+```diff

 **Grant Access Permission for Android 6.0**
 
 Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app. So adding permissions in `AndroidManifest.xml` won't work in Android 6.0 devices. To grant permissions in runtime, you might use modules like [react-native-android-permissions](https://github.com/lucasferreira/react-native-android-permissions).
 
 When download large files on Android it is recommended to use `Download Manager`, it supports lot of native features like progress bar, and notification, also the download task will be handled by OS, and more effective.
 
+When using DownloadManager, `fileCache` and `path` properties in `config` will not take effect, because Android DownloadManager can only store files to external storage. When download complete, DownloadManager will generate a file path so that you can deal with it.
+
 ```js
 RNFetchBlob
     .config({
-        // Optional, if not specified, the file will download to system default path
-        path : DOWNLOAD_DEST,
         addAdnroidDownloads : {
             useDownloadManager : true, // <-- this is the only thing required
             // Optional, override notification setting (default to true)
         }
     })
     .fetch('GET', 'http://example.com/file/somefile')
+    .then((resp) => {
+      // the path of downloaded file
+      resp.path()
+    })

-
-## API
-
-### `config(options:RNFetchBlobConfig):fetch`
-
-`0.5.0`
-
-Config API was introduced in `v0.5.0` which provides some options for the `fetch` task.
-
-see [RNFetchBlobConfig](#user-content-configoptionsrnfetchblobconfigfetch)
-
-### `fetch(method, url, headers, body):Promise<FetchBlobResponse>`
-
-`legacy`
-
-Send a HTTP request uses given headers and body, and return a Promise.
-
-#### method:`string` Required
-HTTP request method, can be one of `get`, `post`, `delete`, and `put`, case-insensitive.
-#### url:`string` Required
-HTTP request destination url.
-#### headers:`object` (Optional)
-Headers of HTTP request, value of headers should be `stringified`, if you're uploading binary files, content-type should be `application/octet-stream` or `multipart/form-data`(see examples above).
-#### body:`string | Array<Object>` (Optional)
-Body of the HTTP request, body can either be a BASE64 string, or an array contains object elements, each element have 2  required property `name`, and `data`, and 1 optional property `filename`, once `filename` is set, content in `data` property will be consider as BASE64 string that will be converted into byte array later.
-When body is a base64 string , this string will be converted into byte array in native code, and the request body will be sent as `application/octet-stream`.
-
-### `fetch(...).progress(eventListener):Promise<FetchBlobResponse>`
-
-`0.4.2`
-
-Register on progress event handler for a fetch request.
-
-#### eventListener:`(sendOrReceivedBytes:number, totalBytes:number)`
-
-A function that triggers when there's data received/sent, first argument is the number of sent/received bytes, and second argument is expected total bytes number.
-
-### `wrap(path:string):string`
-
-Simply prepend `RNFetchBlob-file://` to a path, this make the file path becomes recognizable to native `fetch` method.
-
-### `session(name:string):RNFetchBlobSession`
-
-Session API helps managing cached files, the following code, will try to return an existing session object with the given `name`, if it does not exist, create one.
-
-```js
-RNFetchBlob.session('mysession')
-```
-see [Class RNFetchBlobSession](#user-content-rnfetchblobsession) for usage.
-
-### `base64`
-
-
-`0.4.2`
-
-A helper class simply uses [base-64](https://github.com/mathiasbynens/base64) for decode and encode BASE64 data.
-
-```js
-RNFetchBlob.base64.encode(data)
-RNFetchBlob.base64.decode(data)
-```
-
-### `fs`
-
-`0.5.0`
-
-#### dirs
-
-This constant is a hash map contains common used folders:
-- DocumentDir
-- CacheDir
-- DCIMDir (Android Only)
-- DownloadDir (Android Only)
-- MusicDir (Android Only)
-- PictureDir (Android Only)
-- MovieDir (Android Only)
-- RingtoneDir (Android Only)
-
-```js
-const dirs = RNFetchBlob.fs.dirs
-console.log(dirs.DocumentDir)
-console.log(dirs.CacheDir)
-console.log(dirs.DCIMDir)
-console.log(dirs.DownloadDir)
-```
-> If you're going to make downloaded file visible in Android `Downloads` app, please see [Show Downloaded File and Notification in Android Downloads App](#user-content-show-downloaded-file-and-notifiction-in-android-downloads-app).
-
-### createFile(path, data, encoding):Promise
-
-#### path:`string`
-The path which this new file will be created.
-#### data:`string` | `Array<number>`
-Content of the new file, when `encoding` is `ascii`, this argument shoud be an array contains number 0~255.
-#### encoding:`utf8` | `base64` | `ascii`
-Encoding of content.
-
-the following expressions are equivalent.
-
-```js
-const fs = RNFetchBlob.fs
-const base64 = RNFetchBlob.base64
-fs.createFile(NEW_FILE_PATH, 'foo', 'utf8')
-fs.createFile(NEW_FILE_PATH, [102, 111, 111], 'ascii')
-fs.createFile(NEW_FILE_PATH, base64.encode('foo'), 'base64')
-```
-
-### writeFile(path:string, content:string | Array<number>, encoding:string, append:boolean):Promise<WriteStream>
-
-`0.6.0`
-

-Encoding of input data.
-#### append:`boolean`(optional, default to `false`)
-Will new data append after existing file or not.
-
-```js
-
-// write UTF8 data to file
-RNFetchBlob.fs.writeFile(PATH_TO_WRITE, 'foo', 'utf8', false)
-              .then(()=>{ ... })
-// write bytes to file
-RNFetchBlob.fs.writeFile(PATH_TO_WRITE, [102,111,111], 'ascii', true)
-              .then(()=>{ ... })
-// write base64 data to file
-RNFetchBlob.fs.writeFile(PATH_TO_WRITE, RNFetchBlob.base64.encode('foo'), 'base64', true)
-              .then(()=>{ ... })
-
-// the file should have content like this
-// foofoofoo
-
-```
-
-### writeStream(path:string, encoding:string, append:boolean):Promise<WriteStream>

-
-## Types
-
-### RNFetchBlobConfig
-
-A set of configurations that will be injected into a `fetch` method, with the following properties.
-
-#### indicator:boolean
-  `0.5.6`
-  Set this property to `true` to display a network indicator on status bar, this feature is only supported on IOS.
-
-#### trusty:boolean
-  `0.5.3`
-  Set this property to `true` will allow the request create connection with server have self-signed SSL certification. This is not recommended to use in production.
-
-#### fileCache:boolean
-  Set this property to `true` will makes response data of the `fetch` stored in a temp file, by default the temp file will stored in App's own root folder with file name template `RNFetchBlob_tmp${timestamp}`.
-#### appendExt:string
-  Set this property to change temp file extension that created by `fetch` response data.
-#### path:string
-  When this property has value, `fetch` API will try to store response data in the path ignoring `fileCache` and `appendExt` property.
-#### addAndroidDownloads:object (Android only)
-  This is an Android only property, it should be an object with the following properties :
-  - useDownloadManager : download file using Android download manager or not.
-  - title : title of the file
-  - description : File description of the file.
-  - mime : MIME type of the file. By default is `text/plain`
-  - mediaScannable : A `boolean` value, see [Officail Document](https://developer.android.com/reference/android/app/DownloadManager.html#addCompletedDownload(java.lang.String, java.lang.String, boolean, java.lang.String, java.lang.String, long, boolean))
-  - notification : A `boolean` value decide whether show a notification when download complete.
-
-### RNFetchBlobResponse
-
-When `fetch` success, it resolve a `FetchBlobResponse` object as first argument. `FetchBlobResponse` object has the following methods (these method are synchronous, so you might take quite a performance impact if the file is big)
-
-#### base64():string
-  returns base64 string of response data (done in native context)
-#### json():object
-  returns json parsed object (done in js context)
-#### text():string
-  returns decoded base64 string (done in js context)
-#### path():string
-  returns file path if the response data is cached in file
-#### readFile(encoding:string):Promise
-  return a promise that resolves response data when possible.
-#### readStream(encoding:string, bufferSize:number):Promise<RNFetchBlobSession>
-  return a promise that resolves a `readStream` object when possible.
-#### session(name:string):RNFetchBlobSession
-  when the response data is cached in a file, this method adds the file into the session. The following usages are equivalent.
-```js
-RNFetchBlob.session('session-name').add(resp.path())
-// or
-resp.session('session-name')
-```
-
-### RNFetchBlobStat
-
-Statistic data of a file, see the following sample object.
-
-```js
-{
-    // file name
-    filename : 'foo.png',
-    // folder of the file or the folder itself
-    path : '/path/to/the/file/wihout/file/name/',
-    // size in byte
-    size : 4901,
-    // `file` or `directory`
-    type : 'file',
-    // last modified timestamp
-    lastModified : 141323298
-}
-```
-
-
-### RNFetchBlobSession
-
-A `session` is an object that helps you manage files. It simply maintains a list of file path and let you use `dispose()`to delete files in this session once and for all.
-
-#### add(path:string):RNFetchBlobSession
-  Add a file path to this session.
-#### remove(path:string):RNFetchBlobSession
-  Remove a file path from this session (not delete the file).
-#### list():Array<String>
-  Returns an array contains file paths in this session.
-#### dispose():Promise
-  Delete all files according to paths in the session.

-#### Android Media Scanner, and Downloads App Support
+#### Android Media Scanner, and Download Manager Support
+
+If you want to make a file in `External Storage` becomes visible in Picture, Downloads, or other built-in apps, you will have to use `Media Scanner` or `Download Manager`.
 
-If you want to make a file in `External Storage` becomes visible in Picture, Music, or other built-in apps, you will have to use `Media Scanner`. To make this happend, use `scanFile` method in `fs`.
+**Media Scanner**
 
+Media scanner scan the file and categorize by given MIME type, if MIME type not specified, it will try to resolve the file using its file extension.
 
 ```js
 
-RNFetchBlog
+RNFetchBlob
     .config({
         // DCIMDir is in external storage
         path : dirs.DCIMDir + '/music.mp3'
     })
 ```
 
-If mime is null or undefined, then the mime type will be inferred from the file extension.

+            // Optional, override notification setting (default to true)
+            notification : false,
+            // Optional, but recommended since android DownloadManager will fail when
+            // the url does not contains a file extension, by default the mime type will be text/plain
+            mime : 'text/plain',
+            description : 'File downloaded by download manager.'
+        }

-
-Config API was introduced in `v0.5.0` which provides some options for the `fetch` task.
-
-see [RNFetchBlobConfig](#user-content-configoptionsrnfetchblobconfigfetch)
-
-### `fetch(method, url, headers, body):Promise<FetchBlobResponse>`
-
-`legacy`
-
-Send a HTTP request uses given headers and body, and return a Promise.
-
-#### method:`string` Required
-HTTP request method, can be one of `get`, `post`, `delete`, and `put`, case-insensitive.
-#### url:`string` Required
-HTTP request destination url.
-#### headers:`object` (Optional)
-Headers of HTTP request, value of headers should be `stringified`, if you're uploading binary files, content-type should be `application/octet-stream` or `multipart/form-data`(see examples above).
-#### body:`string | Array<Object>` (Optional)
-Body of the HTTP request, body can either be a BASE64 string, or an array contains object elements, each element have 2  required property `name`, and `data`, and 1 optional property `filename`, once `filename` is set, content in `data` property will be consider as BASE64 string that will be converted into byte array later.
-When body is a base64 string , this string will be converted into byte array in native code, and the request body will be sent as `application/octet-stream`.
-
-### `fetch(...).progress(eventListener):Promise<FetchBlobResponse>`
-
-`0.4.2`
-
-Register on progress event handler for a fetch request.
-
-#### eventListener:`(sendOrReceivedBytes:number, totalBytes:number)`
-
-A function that triggers when there's data received/sent, first argument is the number of sent/received bytes, and second argument is expected total bytes number.
-
-### `wrap(path:string):string`
-
-Simply prepend `RNFetchBlob-file://` to a path, this make the file path becomes recognizable to native `fetch` method.
-
-### `session(name:string):RNFetchBlobSession`
-
-Session API helps managing cached files, the following code, will try to return an existing session object with the given `name`, if it does not exist, create one.
-
-```js
-RNFetchBlob.session('mysession')
-```
-see [Class RNFetchBlobSession](#user-content-rnfetchblobsession) for usage.
-
-### `base64`
-
-
-`0.4.2`
-
-A helper class simply uses [base-64](https://github.com/mathiasbynens/base64) for decode and encode BASE64 data.
-
-```js
-RNFetchBlob.base64.encode(data)
-RNFetchBlob.base64.decode(data)
-```
-
-### `fs`
-
-`0.5.0`
-
-#### dirs
-
-This constant is a hash map contains common used folders:
-- DocumentDir
-- CacheDir
-- DCIMDir (Android Only)
-- DownloadDir (Android Only)
-- MusicDir (Android Only)
-- PictureDir (Android Only)
-- MovieDir (Android Only)
-- RingtoneDir (Android Only)
-
-```js
-const dirs = RNFetchBlob.fs.dirs
-console.log(dirs.DocumentDir)
-console.log(dirs.CacheDir)
-console.log(dirs.DCIMDir)
-console.log(dirs.DownloadDir)
-```
-> If you're going to make downloaded file visible in Android `Downloads` app, please see [Show Downloaded File and Notification in Android Downloads App](#user-content-show-downloaded-file-and-notifiction-in-android-downloads-app).
-
-### createFile(path, data, encoding):Promise
-
-#### path:`string`
-The path which this new file will be created.
-#### data:`string` | `Array<number>`
-Content of the new file, when `encoding` is `ascii`, this argument shoud be an array contains number 0~255.
-#### encoding:`utf8` | `base64` | `ascii`
-Encoding of content.
-
-the following expressions are equivalent.
-
-```js
-const fs = RNFetchBlob.fs
-const base64 = RNFetchBlob.base64
-fs.createFile(NEW_FILE_PATH, 'foo', 'utf8')
-fs.createFile(NEW_FILE_PATH, [102, 111, 111], 'ascii')
-fs.createFile(NEW_FILE_PATH, base64.encode('foo'), 'base64')
-```
-
-### writeStream(path:string, encoding:string, append:boolean):Promise<WriteStream>
-
-#### path:`string`
-The path to the file the stream is writing to.
-#### encoding:`utf8` | `base64` | `ascii`
-Encoding of input data.
-#### append:`boolean`(optional, default to `false`)
-Will new data append after existing file or not.
-
-Calling `writeStream` method will returns a Promise, which resolves a `RNFetchBlobWriteSteam` instance when stream opened successfully.
-
-```js
-// write utf8 data
-RNFetchBlob.fs.writeStream(PATH_TO_WRITE, 'utf8')
-    .then((stream) => {
-        stream.write('foo')
-        return stream.close()
-    })

-        stream.write([111,111])
-        return stream.close()
-    })
-// write BASE64
-RNFetchBlob.fs.writeStream(PATH_TO_WRITE, 'base64')
-    .then((stream) => {
-        stream.write(RNFetchBlob.base64.encode('foo'))
-        return stream.close()
-    })
-
-```

-
-```js
-RNFetchBlob.fs.readStream(PATH_TO_READ, 'utf8')
-    .then((stream) => {
-        let data = ''

-## Types
-
-### RNFetchBlobConfig
-
-A set of configurations that will be injected into a `fetch` method, with the following properties.
-
-#### indicator:boolean
-  `0.5.6`
-  Set this property to `true` to display a network indicator on status bar, this feature is only supported on IOS.
-
-#### trusty:boolean
-  `0.5.3`
-  Set this property to `true` will allow the request create connection with server have self-signed SSL certification. This is not recommended to use in production.
-
-#### fileCache:boolean
-  Set this property to `true` will makes response data of the `fetch` stored in a temp file, by default the temp file will stored in App's own root folder with file name template `RNFetchBlob_tmp${timestamp}`.
-#### appendExt:string
-  Set this property to change temp file extension that created by `fetch` response data.
-#### path:string
-  When this property has value, `fetch` API will try to store response data in the path ignoring `fileCache` and `appendExt` property.
-#### addAndroidDownloads:object (Android only)
-  This is an Android only property, it should be an object with the following properties :
-  - title : title of the file
-  - description : File description of the file.
-  - mime : MIME type of the file. By default is `text/plain`
-  - mediaScannable : A `boolean` value, see [Officail Document](https://developer.android.com/reference/android/app/DownloadManager.html#addCompletedDownload(java.lang.String, java.lang.String, boolean, java.lang.String, java.lang.String, long, boolean))
-  - notification : A `boolean` value decide whether show a notification when download complete.
-
-### RNFetchBlobResponse
-
-When `fetch` success, it resolve a `FetchBlobResponse` object as first argument. `FetchBlobResponse` object has the following methods (these method are synchronous, so you might take quite a performance impact if the file is big)
-
-#### base64():string
-  returns base64 string of response data (done in native context)
-#### json():object
-  returns json parsed object (done in js context)
-#### text():string
-  returns decoded base64 string (done in js context)
-#### path():string
-  returns file path if the response data is cached in file
-#### session(name:string):RNFetchBlobSession
-  when the response data is cached in a file, this method adds the file into the session. The following usages are equivalent.
-```js
-RNFetchBlob.session('session-name').add(resp.path())
-// or
-resp.session('session-name')
-```
-
-### RNFetchBlobStat
-
-Statistic data of a file, see the following sample object.
-
-```js
-{
-    // file name
-    filename : 'foo.png',
-    // folder of the file or the folder itself
-    path : '/path/to/the/file/wihout/file/name/',
-    // size in byte
-    size : 4901,
-    // `file` or `directory`
-    type : 'file',
-    // last modified timestamp
-    lastModified : 141323298
-}
-```
-
-
-### RNFetchBlobSession
-
-A `session` is an object that helps you manage files. It simply maintains a list of file path and let you use `dispose()`to delete files in this session once and for all.
-
-#### add(path:string):RNFetchBlobSession
-  Add a file path to this session.
-#### remove(path:string):RNFetchBlobSession
-  Remove a file path from this session (not delete the file).
-#### list():Array<String>
-  Returns an array contains file paths in this session.
-#### dispose():Promise
-  Delete all files according to paths in the session.
