Skip to the bottom of this post, copy the BasicImageDownloader javadoc version here into your project, implement the OnImageLoaderListener interface and you're done. Note : though the BasicImageDownloader handles possible errors and will prevent your app from crashing in case anything goes wrong, it will not perform any post-processing e.
downsizing on the downloaded Bitmaps. How to download text pictures from android this post has received quite a lot of attention, I have decided to completely rework it to prevent the folks from using deprecated technologies, bad programming practices or just doing silly things - like looking for "hacks" to run network on the main thread or accept all SSL certs.
I've created a demo project named "Image Downloader" that demonstrates how to download and save an image using my own downloader implementation, the Android's built-in DownloadManager as well as some popular open-source libraries, how to download text pictures from android. You can view the complete source code or download the project on GitHub.
In my conclusion at the end of this post I will share my humble opinion about the proper use-case for each particular way of image downloading I've mentioned. Let's start with an own implementation you can find the code at the end of the post.
First of all, this is a Basic ImageDownloader and that's it. All it does is connecting to the given url, reading the data and how to download text pictures from android to decode it as a Bitmaptriggering the OnImageLoaderListener interface callbacks when appropriate. The advantage of this approach - it is simple and you have a clear overview of what's going on.
Note: in case of large images, you might need to scale them down. Android DownloadManager is a way to let the system handle the download for you. It's actually capable of downloading any kind of files, not just images.
You may let your download happen silently and invisible to the user, or you can enable the user to see the download in the notification area.
You can also register a BroadcastReceiver to get notified after you download is complete. The setup is pretty much straightforward, refer to the linked project for sample code.
Using the DownloadManager is generally not a good idea if you also want to display the image, since you'd need to read and decode the saved file instead of just setting the downloaded Bitmap into an ImageView. The DownloadManager also does not provide any API for you app to track the download progress. Now the introduction of the great stuff - the libraries. I will start with Volleya powerful library created by Google and covered by the official documentation.
While being a general-purpose networking library not specializing on images, Volley features quite a powerful API for managing images. You will need to implement a Singleton class for managing Volley requests and you are good to go. You might want to replace your ImageView with Volley's NetworkImageViewso the download basically becomes a one-liner:. If you need more control, this is what it looks like to create an ImageRequest with Volley:.
It is worth mentioning that Volley features an excellent error handling mechanism by providing the VolleyError class that helps you to determine the exact cause of an error. If your app does a lot of networking and managing images isn't its main purpose, then Volley it a perfect fit for you, how to download text pictures from android. Square's Picasso is a well-known library which will do all of the image loading stuff for you. Just displaying an image using Picasso is as simple as:.
For more control you can implement the Target interface and use it to load your image into - this will provide callbacks similar to the Volley example. Check the demo project for examples. Picasso also lets you apply transformations to the downloaded image and there are even other libraries around that extend those API.
Universal Image Loader is an another very popular library serving the purpose of image management. It uses its own ImageLoader that once initialized has a global instance which can how to download text pictures from android used to download how to download text pictures from android in a single line of code:.
The opts argument in this example is a DisplayImageOptions object. Refer to the demo project to learn more. Similar to Volley, UIL provides the FailReason class that enables you to check what went wrong on download failure. Note : the author has mentioned that he is no longer maintaining the project as of Nov 27th, But since there are many contributors, we can hope that the Universal Image Loader will live on. Facebook's Fresco is the newest and IMO the most advanced library that takes image management to a new level: from keeping Bitmaps off the java heap prior to Lollipop to supporting animated formats and progressive JPEG streaming.
To learn more about ideas and techniques behind Fresco, refer to this post. The basic usage is quite simple. Note that you'll need to call Fresco, how to download text pictures from android. initialize Context ; only once, how to download text pictures from android, preferable in the Application class.
Initializing How to download text pictures from android more than once may lead to unpredictable behavior and OOM errors. Fresco uses Drawee s to display images, you can think of them as of ImageView s:. As you can see, a lot of stuff including transformation options gets already defined in XML, so all you need to do to display an image is a one-liner:. Fresco provides an how to download text pictures from android customization API, which, under circumstances, can be quite complex and requires the user to read the docs carefully yes, sometimes you need to RTFM.
Note that the following text reflects my personal opinion and should not be taken as a postulate. In case you missed that, the Github link for the demo project. I have just came from solving this problem on and I would like to share the complete code that can download, save to the sdcard and hide the filename and retrieve the images and finally it checks if the image is already there.
The url comes from the database so the filename can be uniquely easily using id. Why do you really need your own code to download it?
How about just passing your URI to Download manager? I have a simple solution which is working perfectly. The code is not mine, I found it on this link. Here are the steps to follow:. It needs a context, better to use the pass in the application context by getApplicationContext. This method can be dumped into your Activity class or other util classes.
This private class need to be placed in your Activity class as a subclass. After the image is downloaded, in the onPostExecute method, it calls the saveImage method defined above to save the image. The AsyncTask for downloading the image is defined, but we need to execute it in order to run that AsyncTask.
To do so, write this line in your onCreate method in your Activity class, or in an onClick method of a button or other places you see fit. jpeg, check this post for accessing this directory from your device. IMO this solves the issue! If you want further steps such as load the image you can follow these extra steps:.
After the image is downloaded, we need a way to load the image bitmap from the internal storage, so we can use it. This method takes two paramethers, a context and an image file name, without the full path, the context. openFileInput imageName will look up the file at the save directory when this file name was saved in the above saveImage method. Now we have everything we needed for setting the image of an ImageView or any other Views that you like to use the image on.
jpeg" ; if file. delete Log. jpeg deleted! Droidman post is pretty comprehensive. Volley works good with small data of few kbytes. When I tried to use the 'BasicImageDownloader. java' the Android Studio gave me warning that the AsyncTask class should to be static or there could be leaks.
I used Volley in another test app and that kept crashing because of leaks so I am worried about using Volley for the image downloader images can be few kB. I used Picasso and it worked well, there is small change probably an update on Picasso from what is posted above.
Below code worked for me:. As Google tells, for now, don't forget to add also readable on external storage in the manifest :. html GetWritePermission. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?
