i using BCTextEngine to my app, when debug didn't have any errors, but when i relased to end user, crashlytic receive many bugs.
i still can't figure out what cause this error.

Can you upload the project or send it to [email protected] ?

I already sent to email.

Thank you.

Looks very nice!
Post a screenshot if possible.

I was able to reproduce an out of memory error by changing the screen orientation. Removing the unused background layer seems to fix this issue: https://www.b4x.com/android/forum/t...xt-engine-bbcode-parser-rich-text-view.106207
Update to the latest version, it will reduce the memory required.

Another thing that worth doing is to request more memory by adding this line to the manifest editor:

SetApplicationAttribute(android:largeHeap, "true")

If you still get errors with the updated version then post the full error message.

This is a different issue. BCTextEngine generates a bitmap with all the text. In this case the generated bitmap is too tall (it will happen on devices with large screens and high DPI). You will need to split it into two BBCodeViews. You can make them as tall as their content and then add them to xCLV one after another.

how to make the BBCodeViews tall same as my content?

 

[Erel]

Try this:

load_text1
BBCodeView1.sv.Height = BBCodeView1.sv.ScrollViewContentHeight + 10dip
BBCodeView1.mBase.Height = BBCodeView1.sv.Height

 

[dragonguy]

Try this:

load_text1
BBCodeView1.sv.Height = BBCodeView1.sv.ScrollViewContentHeight + 10dip
BBCodeView1.mBase.Height = BBCodeView1.sv.Height

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Private TextEngine As BCTextEngine
    Private BBCodeView1 As BBCodeView
    Private clv1 As CustomListView
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("1")
    BBCodeView1.Initialize("","")
    TextEngine.Initialize(Activity)
    load_text1
    BBCodeView1.sv.Height = BBCodeView1.sv.ScrollViewContentHeight + 10dip
    BBCodeView1.mBase.Height = BBCodeView1.sv.Height

End Sub

Sub load_text1
clv1.Add(BBCodeView1,"")
End Sub

i get error

You should never initialize BBCodeView yourself. It should be added with the designer.

 

[dragonguy]

Solved the problem when add two BBCodeView!
Look nice!
Thanks!

The memory issue is now solved with the lazy loading feature: https://www.b4x.com/android/forum/t...rser-rich-text-view.106207/page-5#post-682448
