How to download image task in android code

URL; import java. URLConnection; import java. HashSet; import java. The URL is probably not pointing to a file".

What about the onPictureTaken callback which gives the picture as byte[], can one get a URL to that picture, straight from the camera? Or is basic old outputStream the only way in Android to save a picture which was taken by a camera without using the built in intent? That seems strange, because the natural thing to do after onPictureTaken is of course to save it.

Is there no particular support for doing that? Tombola Hi! This post is about downloading a picture from the web. But to answer your question as far as I've understood it : the common way of saving a camera picture is getting its path from the Cursor in the onActivityResult method , then creating a Bitmap using that path. BartBurg this question is about downloading and saving an image. But you're right at some point, since there's a write method, there also should be a read method for the sake of completeness.

I will add it in the next update to this post soon. Can you please provide an example using this BasicImageDownloader? JaydevKalivarapu please check the demo app on GitHub source class containing example — Droidman.

Nasz Njoka Sr. Note : while this example could generally work, it does not provide any error handling and also lacks some basic understanding of AsyncTask 's advantages proper use of parametrization, parallel execution.. Please refer to my examples below for details. Yes Droidman, I agree with you. This piece of code should be taken as a tamplate and one has to complete it on his own, including error handling.

By the way, your code lacks error handling too. What will happened to your connection and streams in case of IOException? Androider please take a closer look at my download method, particularly the doInBackground method of the task that I use. An IOException would land in the catch Throwable e block, resulting in an ImageError being returned and the onError callback being triggered.

The ImageError object will contain the original stack trace and the cause of the occurred Exception — Droidman. Yes, but your connection will not be disconnected and your streams will not be closed — Androider. Androider ah, I see your point.

Though I never noticed any suspicious leaks on my test devices, this behavior might be different on other devices. Thanks for the hint - I have updated the code — Droidman. Show 1 more comment.

If you want further steps such as load the image you can follow these extra steps: 4. To get the image full path by image name. Check if the image file exists. Note that the above approach of saving the image on app's private storage has 2 downsides: 1 the image will be only available to your app and 2 you should avoid saving images to app's private storage since it's not intended for large content.

It will not work with Marshmallow and later because of the new runtime permissions. I will post a version that does do this shortly. The emulator did not work with the internet.

I was not able to using the browser on the phone to surf the internet and so the AVD would timeout when trying to download the image. I had to start the emulator from the command line using my particular dns server as follows Doing this the internet on the emulator was able to work. Here you can see that the URI "sdcard" is a link to another storage folder where you will be able to see your image that has been downloaded. It is possible to download a file manager by dragging and a dropping an APK onto your emulator.
