android share image from url
I want to share an image using the code:
I made a button that call the code above. The share intent open but I got if I click on «Share by MMS»: «cannot add this picture to your message». If Facebook I got only a text area without my picture.

An adapted version of @eclass’s answer which doesn’t require use of an ImageView:
Use Picasso to load the url into a Bitmap
Convert Bitmap into Uri
I use these codes from this tutorial
then add this to your activity
then add your application manifest
You need to use a local file. Like this:
If your image is on remote server download it to the device first.
After a lot of pondering, here is the code that I found to be working for me! I think this is one of the simplest versions of code to achieve the given task using Picasso. There is no need to create an ImageView object.
Here, bmp is a class level Bitmap variable and url will be the dynamic Internet url to your image for sharing. Also, instead of keeping the code to share inside the onBitmapLoaded() function, it can also be kept inside another handler function and later called from the onBitmapLoaded() function. Hope this helps!
First you need to load image in the glide. Then you can share it to anywhere. Code to load image from glide (image is being saved to storage, you can delete it later).

Best method to download image from url in Android
I’m using below method to download single image from url
Sometimes I get an outofmemory exception.
I am unable to catch outofmemory exception. The app will close. How to prevent this?
Is there a better method for downloading images that is also faster?

Try to use this:
And for OutOfMemory issue:
I use this library, it’s really great when you have to deal with lots of images. It downloads them asynchronously, caches them etc.
As for the OOM exceptions, using this and this class drastically reduced them for me.

Step 1: Declaring Permission in Android Manifest
First thing to do in your first Android Project is you declare required permissions in your ‘AndroidManifest.xml’ file.
For Android Download Image from URL, we need permission to access the internet to download file and read and write internal storage to save image to internal storage.
Add following lines of code at the top of tag of AndroidManifest.xml file:
Step 2: Request required permission from user
Android allows every app to run in a sandbox. If an app needs to access certain resources or information outside that sandbox, it needs to request permission from user.
From Android 6.0 onward, Google wants developers to request permission from user from within the app, for more details on permissions read this.
Therefore for Android Download Image from URL, you’ll need to request Read Storage and Write
For this, we will use the following lines of code to first check if the required permission is already granted by the user, if not then we will request permission for storage read and write permission.
We’re creating a method ‘Downlaod Image’, you can simple call this wherever you need to download the image.
Now that we have requested and been granted the user permission, to start with android download image from url, we will create an AsyncTask, as you are not allowed to run a background process in the main thread.
In the above give lines of code, a URL and Bitmap is created, using BitmapFactory.decodeStream, file is downloaded.
The File path is created to save the image (We have created a folder named ‘AndroidDvlpr’ in DIRECTORY_PICTURES) and download is initialized.
After downloading the file MediaScannerConnection, is called to read metadata from the file and add the file to the media content provider so the image is available for the user.
In the above lines of code, we have also created a method, showToast() to show Toast. complete code here:

How do you use an image referenced by URL in an ImageView ?
23 Answers 23
Make sure you have the following permissions set in your AndroidManifest.xml to access the internet.
1. Picasso allows for hassle-free image loading in your application—often in one line of code!
Use Gradle:
Just one line of code!
2. Glide An image loading and caching library for Android focused on smooth scrolling
Use Gradle:
3. fresco is a powerful system for displaying images on Android applications. Fresco takes care of image loading and display, so you don’t have to.
You’ll have to download the image firstly
Then use the Imageview.setImageBitmap to set bitmap into the ImageView
Anyway people ask my comment to post it as answer. i am posting.
I wrote a class to handle this, as it seems to be a recurring need in my various projects:
UrlImageViewHelper will fill an ImageView with an image that is found at a URL.
The sample will do a Google Image Search and load/show the results asynchronously.
UrlImageViewHelper will automatically download, save, and cache all the image urls the BitmapDrawables. Duplicate urls will not be loaded into memory twice. Bitmap memory is managed by using a weak reference hash table, so as soon as the image is no longer used by you, it will be garbage collected automatically.

Android: How to load Image from URL in ImageView?
Project Description
- In this tutorial, we will see how to load an image from URL into Android ImageView.
- For downloading the image from URL and loading it in ImageView, we use AsyncTask.
Environment Used
- JDK 6 (Java SE 6)
- Eclipse Indigo IDE for Java EE Developers (3.7.1)
- Android SDK 4.0.3 / 4.1 Jelly Bean
- Android Development Tools (ADT) Plugin for Eclipse (ADT version 20.0.0)
- Refer this link to setup the Android development environment
Prerequisites
Android Project
Create an Android project and name it as “ImageViewFromURL“.
strings.xml
Open res/values/strings.xml and replace it with following content.
XML layout file
This application uses XML layout file (main.xml) to display the ImageView.
Open main.xml file in res/layout and copy the following content.
Activity
In src folder, create a new Class and name it as “ImageViewFromURLActivity” in the package “com.theopentutorials.android.views” and copy the following code.
From Android 3.x Honeycomb or later, you cannot perform Network IO on the UI thread and doing this throws android.os.NetworkOnMainThreadException. You must use Asynctask instead as shown below.
- Whenever we need to perform lengthy operation or any background operation we can use Asyntask which executes a task in background and publish results on the UI thread without having to manipulate threads and/or handlers.
- In onCreate(), we create and execute the task to load image from url. The task’s execute method invokes doInBackground() where we open a Http URL connection and create a Bitmap from InputStream and return it.
- Once the background computation finishes, onPostExecute() is invoked on the UI thread which sets the Bitmap on ImageView.
Android includes two HTTP clients: HttpURLConnection and Apache HTTP Client.
For Gingerbread and later, HttpURLConnection is the best choice.
AndroidManifest.xml
Define the activity in AndroidManifest.xml file. To access internet from Android application set the android.permission.INTERNET permission in manifest file as shown below.
Output
Run your application
Project Folder Structure
The complete folder structure of this example is shown below.

Android Download Image From URL
Last Updated: March 15, 2013
In this tutorial, you will learn how to download an image from a URL address into your Android application. We will create a button and on button click will start an AsyncTask class to begin downloading an image from a URL address. So lets begin…
Create a new project in Eclipse File > New > Android Application Project. Fill in the details and name your project DownloadImageTutorial.
Application Name : DownloadImageTutorial
Project Name : DownloadImageTutorial
Package Name : com.androidbegin.downloadimagetutorial
Open your MainActivity.java and paste the following code.
MainActivity.java
In this activity, we have created a Button and an ImageView and on button click will show a progress dialog and start the Download Image AsyncTask class. The download image will be decoded into a bitmap and set into an ImageView. In this tutorial, we’ve hosted the sample image GIF file in our server. Click on this link to see the sample image. https://www.androidbegin.com/wp-content/uploads/2013/07/HD-Logo.gif
Next, create an XML file for your MainActivity graphical layout. Go to res > layout > Right Click on layout > New > Android XML File
Name your new XML file activity_main.xml and paste the following code.
activity_main.xml
Next, change the application name and texts. Open your strings.xml in your res > values folder and paste the following code.
strings.xml
In your AndroidManifest.xml, we need to declare a permission to connect to the Internet. Open your AndroidManifest.xml and paste the following code.
AndroidManifest.xml
Output :
