How to Enable File Upload and Download in Android Webview App | Webview App Development Series Part 19

 Hi Everyone, Welcome to our mobile app developer training. As we are Converting our website to apk, in the previous tutorial we have learned How to Enable Video, Image and File Upload in Android Webview App.

And we also have learned separately How to Upload files in Android Webview App and How to Download the files in the android webview app

Now we will combine uploading files and downloading files code together and will implement them in one Webview app project. 

First of all, you need to add 3 permission for "access camera, write in external storage and Internet" in your AndroidManifest.xml file. 


Code:

Then, we need to take some variables, such as:

Code:


After that, we will move to the "onCreate" method, and in the "WebChromeClient" function we will write the "onShowFileChooser" function.


Code:


Now we will write code for Downloading any files in Android Webview App. First, we will write a function for file saving permission to your device.


Code:


And then we will write code for allowing download file in the Webview app.

Code:


We have finished the coding within the onCreate method, Now we will write several functions outside of the onCreate method.


Code:


That's it, we have finished coding for Uploading and downloading files in the Android webview app. Let's run the project and test.




As you can see in the above picture, Downloading any file and uploading any type of file in Webview App is working perfectly. See you in the next tutorial.

  1. Hi, everything you have taught us about uploading and downloading files works perfectly 10/10, but I would like you to show us how to do practically the same within a fragment and not in an Activity. Since I could not and I am new to this :(
    Thank you in advance :3
