~~Since there was a compile error after updating the SDK this morning I posted a new thread here.~~

Edit: Never mind. Erel had a working tip very fast at hand.

I am wondering if it is possible to set the click effect to a view but keep its background drawable...

dragonguy · Feb 1, 2017

is it we can add control ACSwitch into ACMenuItem?

like below screenshot

dragonguy · Feb 1, 2017

i found the solution.

B4X:

ACToolBarDark1.AddView(main_switch,20%x,10%x,Gravity.RIGHT)

V3.41:

Fix: Change packagename to anywheresoftware.b4a.orbjects to reduce resouce fields

Since V3.41 I can not get

B4X:

Sub Activity_Create(FirstTime As Boolean)
    ...
    ActionBar.InitMenuListener
End Sub

...

Sub ActionBar_NavigationItemClick
    ...
    ' Any stuff here
End Sub

to work i.e. "Up" button does not respond when no menu is present.

Until V3.30 it worked perfectly. Can it be a side effect?

Best regards.

Thanks for reporting. Indeed this is a bug caused by an internal change. I will fix it as soon as possible.

Fixed in V3.42. See the first post.

In b4a v6.8, I get the following error when
Compile the app AppCompatBaseExample3_20

B4X:

java.lang.NoSuchMethodError: No virtual method setText(Ljava/lang/Object;)V in class Lde/amberhome/objects/appcompat/ACButtonWrapper; or its super classes (declaration of 'de.amberhome.objects.appcompat.ACButtonWrapper' appears in /data/app/de.amberhome.appcompat.basicexample-1/base.apk)

Yes. I expected these problems with B4A 6.80. It is because some of the AppCompat Views extend TextViewWrapper and the signature of some methods in this class changed because of the new CharSequence feature. I will update the library very soon.

Please try V3.52 of this library. It should fix the problem.

Thanks for the update so fast, ACButton works fine, but now I have this error

Did you update DesignSupport library, too? FloatlabelEditText is in the DesignSupport library which is also updated.

SandroB4A · Feb 23, 2017

Hello,
I just installed B4A 6.5 and downloaded sdk tools, and I have NOT problems!

But may be instructions on the first page must be updated, with last release of sdk the paths seem to be different, and also libraries name:

In my case I simply copied the appcompat lib (3.51 as I use B4A 6.5), pointed to the last android.jar (25) and all was fine! this is my sdk config.

Which part should be updated in your opinion? I think everything in the instructions is still correct.

SandroB4A · Feb 23, 2017

corwin42 you're right, in the first post there are no indications about paths and instructions are still correct.

I had in mind all the problems encountered by users in later posts where the tip was often: "Copy android-support-v4.jar and android-support-v7-appcompat.jar to support lib" .

Now that procedure is not longer necessary, correct?

Yes. There is no need to copy any support library jar to the customlibs folder anymore.
Since B4A 6.0 the maven repository for the support libraries is used.

JNG · Feb 24, 2017

Yesterday I updated to library ver 3.51(I am using B4A 6.50) and also the latest design support lib I got the following error; Earlier working fine.

Compiling generated Java code. Error
