It is very simple to switch to TabStripViewPager. This is the correct solution.

You need to jetify StdViewPager.

Thanks Erel
I have run jetify but nothing. I made full installation by instruction and nothing again ...

 

[dws]

When i run jetify he say ( All set. Nothing to do! ).
There is another way to jetify StdViewPager ?

 

[Erel]

Make sure that the library is located in the additional libraries folder. Internal libraries will not be jetified.

 

[dws]

Thanks Erel Solved.

Additional instructions for anyone with a similar problem. ( java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/ )

1. Copy the relevant library from the folder (C: \ Program Files (x86) \ Anywhere Software \ Basic4android \ Libraries)
2. Paste in your folder (AdditionalLibs)
3. Execute the selection from the Tools menu (Jetifier)
4. Return the library from the folder (AdditionalLibs) to the folder (C: \ Program Files (x86) \ Anywhere Software \ Basic4android \ Libraries)
5. Open And everything works normally ...

Why are you placing additional libraries in the IDE libraries folder? They are the reason that the additional libraries folder is available to house them.

Give the example of libraries already in the IDE
