Android Network get pictures and save on Local

There are three steps to getting a picture on the network:

First, set permissions to connect to the network and write to read the SD card. Second, network access to obtain data flow. Third, create a folder in the SD card to stream data into a picture format storage.

Note: the Response.getentity (). GetContent () method, and this method can only be called once. otherwise it will error: Java.lang.IllegalStateException:Content has been consumed.

Manifest.xml

Assign permissions, note: Add before <application...>application>

 <uses-permissionAndroid:name= "Android.permission.INTERNET"/>   <uses-permissionAndroid:name= "Android.permission.WRITE_EXTERNAL_STORAGE"/>    <uses-permissionAndroid:name= "Android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>     <uses-permissionAndroid:name= "Android.permission.ACCESS_NETWORK_STATE"/>

Mainactivity.java

Get the data stream for a network picture

HttpGet Header =NewHttpGet ("Your server's picture address"); //Custom Cookies (server return)Header.setheader ("Cookie", "key")); HttpResponse Headerresponse= Httpclient.execute (header);//                                //headerresponse.getentity (). getcontent (); Can only be used once otherwise it will be error content has been consumedInputStream Headerin =headerresponse.getentity (). getcontent ();//data returned by the serverBitmap=Bitmapfactory.decodestream (Headerin); if(Bitmap! =NULL) {savebitmap (bitmap);//Display Image} headerin.close ();

Saved in Location:
