I am developing one application for one real state website. I have to display dynamic content from web I mean website display lots of images and description about the property. i need to populate images and their description in list view similar to flipkart android app do. I don't know how to proceed as of now i have thought i can download all images to sd card and get the text from json and then populate both in custom list. but i feel this is not a good approach as images grows in no it would take memory. Please give me some pointer how i should proceed to get better results.
Thanks in advance. Any help will appreciated.

I'm working on a simple gallery app. I'm wondering what's the best way to create and dsiplay thumbnails. I was thinking about using ThumbnailUtils, making thumbnail for new pictures and then store it in app data storage as I assume that doing it every time when user displays all images isn't efficient. Though I'm not so sure what's better memory-wise. To load an image into ImageView which is part of RecyclerView item I'm using Glide. I don't know if .thumbnail(...) does what I want so I think I need to create thumbnails myself. Could someone show me the correct way to do this? I want the app to load quickly so it's obvious I can't load full resolution images to recycler.
The best way for your result is to use the GridLayout. I wrote an answer yesterday how to achieve that Widget. Take a look. Cheers!
I'm new to android and am trying to create an app that allows the user to take a picture which is then stored in external storage, im storing these pictures in a specific folder on the device and know how to display one specific picture from that folder but I don't know how to display a list of all the pictures.
Any help would be much appreciated as im really struggling with this and am finding it difficult to find out how to do it online.

I would like to ask advise if displaying pdf inside gridview instead of image is possible. I have tried to display list of websites in gridview using webview. Now, I want to make it a list of pdf files inside gridview. Normally same with if you open your folder in your linux laptop and have the thumbnails of your pdf, things like that. I want to achieve that in my application. I would really appreciate any of your advice, no codes needed cause i will handle it my self. I just want to have some theories. thanks and HAPPY NEW YEAR GUYS
I think what you're going to have to is convert the pdf's into a bitmap first, then load into an ImageView, check out this post and also look into other pdf rendering libraries for Android.
I'm building an app that retrieves image of the day from Nasa website.
It basically has 3 TextViews to display title, date and description of the app and an ImageView to display bitmap image from website. And the app works fine.
But I want to add the ability to view these data even when the app is offline and to show previous image along with 3 TextViews onSwipe or onClick...
Can anybody please help me with this?
I've tried searching on how save and retrieve strings but couldn't figure it out.
Have a look at SharedPreferences or if you plan to store more data try a SQLite database. Here is the tutorial to store files in Android.
Nothing is better than Official Docs

In my android mobile app, i have list of lot of (more than 200) images and textviews. For that currently i am using gridview.
But my problem is if i am request all that content at once from server then its take too much time to load and render that images and text in gridview which affect user experience.
So i thought of load only 30-40 items at once and then provide load more button at end. But it is not appropriate way to do this thing.
So can anyone please give me other alternatives to do this thing?
