This way is similar to my try, but I have another problems: user can add more tasks to this current download list check if they're not exist then add them to queue and keep complete tasks in list even user exit app do I need use database for caching?

I wouldn't go for database, because all you need is a list of urls that are done or not. I will go with shared preferences. Even if structure is bit complex e. It will really be just a matter of one or more lines of code to read or write current progress to preferences using Gson in form of json. BTW thats my approach but you can go for Database if you want to. OK, I got it. I will update your code to adapt my requirement and then decide which ones to use.

Thank you very much : — ductran. Can anybody add AndroidManifest. Both receiver and service has to be added right? As I leave the download page and return, will it still show the download progress?

Thanks — Alston. Show 13 more comments. Robert Rowntree Robert Rowntree 6, 2 2 gold badges 22 22 silver badges 41 41 bronze badges. I think it didn't need the observer pattern. I wrapped the progress status into model and put it in adapter list view, then when progress change, I just need to notify dataset change and it can update list view.

Currently, I just consider which pool or queue task should I used. And does I need the database to cache complete download task? Sign up or log in Sign up using Google. Sign up using Facebook.

Are wondering what launcher I am using here? APK Installer is a pretty powerful app. You can manage apps, do batch install or uninstall, and even run a security scan of all the apps on your Android phone.

I understand. I hear you. Especially when you are dealing with apps at once. You would rather install everything from your PC. In case that doesn't happen, you can directly download and install them from here. Make sure you choose your smartphone manufacturer from the list. When you launch the installer again, your device name should be visible on the title bar. Select all the apps you want to install. I will be choosing Weather Channel and Pokemon Go for this test. Once you have selected the apps, you will see more options.

Select the checkbox next to all the apps that you want to install. You can also choose to install these apps on Android at once on SD card. Now click on the Install button at the bottom to begin the installation process.

Just like the app version. Add a comment. Active Oldest Votes. I have implemented the same in one of my production apps: Create a table to add the items which you want to download. Sorting should be based on the time when item was added for download. Consider this as a queue. Also add one column to check if a file is already downloaed or not. If downloaded then remove it from the queue. Create an IntentService which will be responsible for downloading data in background even if application is closed.

This Service should keep running until the table queue is not empty. It should be started only when a new item is added, or when network connection state changes from dead to live. Within this Service you should check if the queue is empty or not. If empty fetch N number of rows from table to add in queue ExecutorService for download.

Alexander What do you say? But after start service user can add new download item any time. On each download item added I need to start download for new download item. If I'm not wrong in your example is getting all download items at the begining of start service?

But in my code after service start user can add new download item — Alexander. Once a IntentService starts it will keep running until task or onHandleIntent is not done with it.
