Android Question [B4xPages] [SOLVED] 'Error occurred on line: 15 (B4XPages)'

[Mashiane]

Ola

I'm pulling my hair out right now. I have followed all examples I could find to make my app work and this just does not want to go away.

Someone said, this setting was possibly the cause

#IncludeTitle: False

and this should be true, I have set this to all my layouts and in the code, dololo.

How does one sort out this error?

 

[josejad]

Sorry, what's the error you're getting?

I'm trying B4XPages now too, and yes, #IncludeTitle is True

 

[Mashiane]

As per Thread title..

'Error occurred on line: 15 (B4XPages)'

 

[josejad]

Hum... Can you upload your project?

 

[Mashiane]

Ok thanks, I will have to PM you.

 

[Mashiane]

Hi, I was cleaning the project to send to you. When I went to the manifest and cleaned it, the error disappeared.

The thing is, I really need the manifest script for my app to work well with B4XPages. I have added a wish here as that is the issue with the app. It goes back to the #IncludeTitle issue.

[B4xPages] Request support to hide the "page" that displays before the Main Activity is shown

Ola Before the main activity gets shown, there is a "splash" screen that's gets displayed. This is usually a blank white page with a page title. The code in this manifest script helps in "hiding" it. This script was found somewhere in the forum and it works perfectly...

I thank you.

 

[josejad]

Yes, same error here adding that code to the manifest.
But the error is in B4XPages code, not in Main #IncludeTitle: False line.

Exactly...

As per Thread title..

'Error occurred on line: 15 (B4XPages)'

First, I can help you about that copy & past:

Select the text (the thread title here!), then the eraser icon on the post tool bar, to remove the formatting

I don't understand anything from this thread.

1. Post the full error message.
2. Tell us what you changed.
3. Tell us why you changed it.

If you want to create a splash screen: https://www.b4x.com/search?query=b4x+splash

Hi @Erel

To provide more clarity on this, there are two cases where this has happened.

Case 1: When

#IncludeTitle: False

It raises this error. As soon as this is made True, the error is never raised again.

This was not my case per ser as I found this here, https://www.b4x.com/android/forum/t...crashes-when-loading-page-with-drawer.120295/ when I was trying to solve my problem. Only to find that the cause was in my manifest when I was cleaning it to PM to Jose.

Case 2: When

This script is included in the manifest

SetActivityAttribute(Main, android:theme, "@style/DarkTheme")
CreateResource(values, theme.xml,
<resources>
   <style name="DarkTheme" parent="android:Theme">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:backgroundDimEnabled">false</item>
  </style>
</resources>)

I found this script here in the forum, it helps with hiding the "page" that displays before the Main activity is shown which was then recorded as a wish in. https://www.b4x.com/android/forum/t...ays-before-the-main-activity-is-shown.127093/


Update:

I found this manifest script here, https://www.b4x.com/android/forum/threads/background-activity-transparent.97900/post-617025

Please focus on a single issue. As I wrote, it is very difficult to understand this thread.

The error happens in a page named B4XNearbyPage in the B4XPage_Appear event. You should check the code there.
Tip: don't treat B4XPages as activities. In most cases you don't need to do anything in the Appear and Disappear events.

Ok thanks, I will relook this, I will mark it solved as it is solved now.
