Hi All,

There are several mentions of a demo app in this thread, yet the OP doesn't contain one, just the libs. Where can I find a sample app for this library?

Maybe the sample app links were removed. However you can check a working example of pager view by installing the following app: https://play.google.com/store/apps/details?id=com.prcamels

Hi Shahid,

Thanks for the link, but I'm actually looking for example code. I've tried to make very simple app but it keeps crashing when I initialize the Photopager. So I'm in need of example code to see what I'm doing wrong.

I have already supplied a sample code of my app here: https://www.b4x.com/android/forum/threads/b4aphotopager-v1-70.40944/page-5#post-333782

Whatever I do, my app crashes with an outofmemory error as soon as I initialise the PhotoPager object.

Please share the error message text here, maybe I could have a look.

Creaky · May 25, 2015

Shahid, I found your example, but it doesn't contain the layout files, so I can't get it to work.
The error I get when I initialise the object on a Galaxy S6 is:

java.lang.OutOfMemoryError: OutOfMemoryError thrown while trying to throw OutOfMemoryError; no stack available

This is my code:

#Region Project Attributes
#ApplicationLabel: B4A Example
#VersionCode: 1
#VersionName:
'SupportedOrientations possible values: unspecified, landscape or portrait.
#SupportedOrientations: unspecified
#CanInstallToExternalStorage: False
#End Region

#Region Activity Attributes
#FullScreen: False
#IncludeTitle: True
#End Region

Sub Process_Globals
'These global variables will be declared once when the application starts.
'These variables can be accessed from all modules.

End Sub

Sub Globals
'These global variables will be redeclared each time the activity is created.
'These variables can only be accessed from this module.
Dim objPager As PhotoPager
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("Layout1")
objPager.Initialize("pg")
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

I have attached a working example for an older version of PhotoPager. I hope it may help you

Yes, this example with the 1.3 library works, how strange!

Creaky · May 27, 2015

Please help. I'm trying to use the B4APhotoPager library in an app for a customer. While the 1.3 example code/app works fine, the library crashes when I incorporate it in my app. I've simply copy/pasted the 1.3 example code in a new activity module in my project and I start the activity by clicking a button in my app.

As soon as the activity tries to initialize the vp object, the app crashes with this line in the Logs:

java.lang.OutOfMemoryError: OutOfMemoryError thrown while trying to throw OutOfMemoryError; no stack available

If I compile and run the 1.3 example on the same device it works just fine.

My deadline is very near and I really need this library to work, someone please lend me a hand!

Here is my code:

B4X:

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: False
#End Region

Sub Process_Globals

End Sub

Sub Globals

    Dim vp As PhotoPager

I think I just found out what the problem was.
The three images (empty_photo.png, ic_error.png, icon.png) in the files dir of the example project ARE REQUIRED by the B4APhotoPager library!
If they are not present you will receive the OutOfMemoryError error.

Giuseppe please mention these files in your documentation

i think this is a general problem more info about it goes here https://code.google.com/p/android/issues/detail?id=60464

itgirl · Nov 4, 2015

More info about this bug can be found https://github.com/chrisbanes/PhotoView/issues/72
theres is a simple solution or workaround for the meanwhile by simply try and catch
onInterceptTouchEvent
could you please update the library with this fix ?

Hi, as I said to Laurent and Susu, I had problems with the shop where I bought the computer. He sold me a computer with used motherboard and faulty.
When I went to talk to him about motherboard , he told me that I had no more warranty and I went to a lawyer to reclaim my motherboard and 2 new SSD were burnt about motherboard .

I'm already working to fix the libraries because I lost part of them was on the ssd.

Thank you for the tip I'll put it in to the library.
