I am using a javascript command to obtain some data from users using:

var sign = window.prompt('Are you feeling lucky?'); // open the window with Text "Are you feeling lucky?"

Is there a way to style the popup that actually starts like this:

The page "file://" says: <-- could we hide this line?
Are you feeling lucky?
[ user input goes here ]
[ cancel ] [ accept ]

Ouch! I was having the very same problem with the so-called openFileDialog4 popup on v3.4.

Guess what!? I used a png file for a customized progress wheel and when the Website2APK Builder loaded the project, I had to reload the progress wheel file (Thanks, God I found the problem!).

I am still suggesting the team to pay attention to all the saved and loaded data from projects. I had some issues with the Customize App Permission feature, checking every item when the project was reloaded.

PS: I cannot change my profile picture on this forum.

[SOLVED] My deepest apologies to the development team. The problem I was having with external links has nothing to do with you. It was me not checking the option JAVASCRIPT API, while compiling the app. I'm really sorry for taking too much of your support-time.

A detailed help file full of samples of each option on the screen. I still feel that I'm not using this software at its full power.

And a new graphics interface *(I am offering my help as a graphic designer, maybe looking for a discount on my licence renewal).

Options to change the size of the splash screen and center it on the screen, plus... change the background color. Imagine that I just want a white screen with a 124x124 transparent .PNG image on the center of the screen.

Google is requesting API28 already. What are you planning to do about it? Please, keep me post. I'm really worried about it. These are the warnings I am receiving while uploading my app:
-----------------------------------------------------------------------------
Target API level requirements from August 2019
Warning:

Your app currently targets API level 27 and must target at least API level 28 to ensure it is built on the latest APIs optimized for security and performance.

From August 2019, new apps must target at least Android 9.0 (API level 28).
From November 2019, app updates must target Android 9.0 (API level 28).

Tip:

Change your app's target API level.
-----------------------------------------------------------------------------

Unoptimized APK
Warning:

This APK results in unused code and resources being sent to users. Your app could be smaller if you used the Android App Bundle. By not optimizing your app for device configurations, your app is larger to download and install on users' devices than it needs to be. Larger apps see lower install success rates and take up storage on users' devices.

Resolution:

Use the Android App Bundle to automatically optimize for device configurations, or manage it yourself with multiple APKs.

This is my first time using this software to compile HTML into APK, thus, I'm still wondering what is the meaning of each option at the UI of the Website2APK software. For example, I'm discovering that the button: Customize App Permissions is there just in case you need to point out that you will be using such permissions (BTW, these are not saved with your project), but... how to use them from your code? That is still unknown for me. The same happens with the Extras option to the right *(v3.2). Some are intuitive, but some are completely weird on their use, like the Allow File Access or Long Clickable. Am I the only newbie here? The same happens with the Splash Screen. How can I control the position of it on the screen. It resizes while vertical, but aligns to right on a tablet, adding a dark gray background color that I'm not interested to use in my app. Help, please. Because helping us, will help you grow even higher! Thank you in advance!

Yes, you are right! It was the missing JDK. Mine was version 7. Thank you! Great support!

I tried moving the file to D: but still keep having the same error. I am using version 3.2

This is my first app with your builder and at the Play Store. So, I'm officially breaking the ice on both. I want to sign the app with my own ID, but how can I do that? Any step-by-step guide?

What is the meaning of signing the app? Would apps created with this software will show that they are yours? Ha, ha... I can see people laughing now. Yes, I'm new and we all were sometime.
