Coding a Share Intent for Images



If you are just arriving at this page; and you are not familiar with with creating Android Apps, we suggest you begin with our tutorials: Coding Android App Pages and How To Create a Simple App in Android

From there follow along with each tutorial lesson.

AIDE and ANDROID STUDIO

We are using AIDE(a mobile coding environment using language java/xml), to create these tutorial apps on our
tablet(7" screen) that has android version 5.0.
Once we build and RUN our app; we then install the app on this same tablet; and the app is also installed on a smart phone that has android version 6.

We are using the AIDE coding editor to code our pages; and then to Create - RUN our apps. AIDE is a SDK coding environment for android devices like a tablet or smartphone. AIDE has a free and paid version. Once you create your apps code pages, you need to RUN the app to build your apk package; then you INSTALL it on your tablet or smartphone. For info on using AIDE, gohere

You can also create; RUN your apps using the code in these tutorials, with Android Studio. Android Studio is for desktop computers. Choose Java XML as the programming language. Android Studio is free to install and use for your android app development. Although not as convenient as testing your app on an actual android device; you can test your newly created app in Android Studio using its' android emulator.

Complete Example Codes are available for each of our tutorials. With these example codes you can make a functioning android app in either AIDE or Android Studio.

COPY/PASTE CODE

First, create a java/xml android template app using AIDE, (or Android Studio). Then you can get the code for this app from the EXAMPLE CODE section on this page. Replace the code on the pages you need to(with our tutorial code); in order to create this app.
Sometimes, new pages have to be created.
All the other coded pages in your app can remain as they are; they don't need to be changed.


This is the App - Share Images
It can share the 'image' from the screen view.
You can share the image to your social sites or other apps on your device

This shows the app screen view with the Share Image Button on the Action Bar.

This shows the Share Prompt that loads once the button
'Share This Views Image' has been clicked.

Where - How To Use Intents to Share Images

There are many methods you can code to share images in your android apps; in this app we have coded one such method.

This Share Image Method includes a 'Share Image Button' which is added to the Action Bar at the top of the view. It will send the 'defined image' to an app of your choice from the populated prompt. The prompt will contain Apps from your device, as well as your social apps like Facebook and Twitter.

As in our previous tutorial for Sharing Text; the image to be shared must be declared in the java coded page - MainActivity.java You can add the Share Image code to any page in your android app that has images.
This Share Image code also sends the selected image to your tablets's file storage.

So, for example, if you selected to share the view's image to Twitter; you click on the Share This Image Button, then click on the Twitter icon; the image is sent to Twitter,(if your already logged in to twitter it will post automatically), and the same image will be sent to the file storage on your tablet as well. You can name the file storage folder anything you want. To do so, just code the name in your MainActivity.java file.




Creating - Naming Your App Using AIDE

When creating your app,(from left menu) choose:
Create New Project;
Then, choose
New Android App(gradle, android Java/xml)
or
Hello World App Java/xml
if your using the original version of AIDE

You can name your app whatever you like; if your using the name as shown in our example code use;

Share Images for the App Name and,
for the package name(next line) use:
com.aac.shareimagesexample;

If you want to name it differently, you can, just change the code to whatever name you choose where it says, com.aac.shareimagesexample, in the coded pages, usually at the top of the java class pages like; MainActivity.java

The Coded Pages


Code for the app - Share Images

For this app you will use these coded pages:

1 layout file, main.xml,(already created, just copy paste this tutorial app code into it and save); located at res/layout/.

1 java page, MainActivity.java,(already created) where we define our layout:
setContentView(R.layout.main).

Just copy paste the code from this tutorial, into the file MainActivity.java; to replace code that's there and save the file.

This tutorial app - Share Images has 1 image; you can download it from our Example Code section; then add it to your drawable-hdpi folder.

Use your tablets File Manager to copy paste the image into the AppProjects/ShareImages/app/src/main/res/drawable-hdpi/ folder.

FYI:

The manifest xml page, (already created)where we define our app's name and activity java page(and other things). Since we are not adding any new activities to our app; we don't need to define any new java pages in the manifest file; so we can leave this page code as it is.


The folder /res/drawable-hdpi also has our ic_launcher.png image;(little green android icon) but we don't need to add it because it was added automatically when we created our android template app.



EXAMPLE CODE - Code For This Tutorial

JUST USE YOUR MOUSE to copy the code for this tutorial App Name is 'Share Images - located at AppProjects/ShareImages in AIDE, open the AIDE app, then open App Projects, THEN select the 'Share Images', app from your files hierachy(left menu); then click on any file from the app, like strings.xml Make sure at top of page, the app name 'Share Images' is there next to AppProjects like so: AppProjects/Share Images, then you know you have the proper App.

Once a file is in the editor, you can edit, save it, then RUN your APP, Install, and Open your app.


Make sure you SAVED EACH PAGE,(or choose automatic saving in AIDE settings) before you RUN your code. SAVE, RUN, INSTALL, OPEN, your App. Once it has been installed on your tablet, you can open it Simply by Clicking on the Android little green App Icon,with the wording 'Share Images' on your tablet. It will be with your other installed apps.

If you make further changes to this App, you need to SAVE, RUN, UPDATE, INSTALL, OPEN the app.
