Android Question AppCompat with ToolBar not working (solved)

[f0raster0]

Hi Guys,

I just bought a new laptop last year.. today want to work with this AppCompat, then I download this example:

AppCompat with ToolBar - minimal example

In most cases AppCompat is no longer needed and will only make things more complicated. B4XPages example with dynamic menu: https://www.b4x.com/android/forum/threads/b4x-menu-badges.133301/ The project attached uses the powerful AppCompat library to replace the built-in ActionBar with a...

I think I read in somewhere about configuration of java or so don't remember..
anyway when i try to run the example I got this error:

I'm using B4A 9.5 at the moment testing with Smartphone Android 9
C:\java\jdk-11.0.1\jdk-11.0.1\bin\javac.exe
C:\Android\platforms\android-28\android.jar

Edit: I found the tutorial..

AppCompat - Make Material Design apps compatible with older Android versions

This library is a wrapper for the Google AppCompat v7 support library. B4A V6.0 or newer is required! From V3.52 on B4A V6.80 or newer is required! If you still use B4A < V6.80, use V3.51 of this library. The main reason for this library is to make your apps compatible with older Android...

I'm using B4A 9.5 at the moment testing with Smartphone Android 9
C:\java\jdk-11.0.1\jdk-11.0.1\bin\javac.exe
C:\Android\platforms\android-28\android.jar

no reason to use 9.5. Update to 9.8; it is free

Follow the installation instructions.

B4A – The simple way to develop native Android apps

B4A includes all the features needed to quickly develop any type of Android app. B4A is used by tens of thousands of developers from all over the world, including companies such as NASA, HP, IBM and others.

It will just work.

it's not important if is free or no.
Sometime is better to keep the version that is working and update later when we have extra free time (just in case)

I think I can solve it following the tutorial.

Anyway, thanks @DonManfred

Look like I have to do that:

App crash "java.lang.NoClassDefFoundError: Failed resolution v4" in sdk update

Hi, I updated to SDK 10 in b4a 9.5 and now get error. #Extends: android.support.v7.app.AppCompatActivity #AdditionalJar: com.android.support:support-v4 i have installed v4 version and it still gives me the same error. Any idea? #Region Project Attributes #ApplicationLabel: B4A Example...

Big mistake to use an older version. There isn't a single advantage of using v9.50 over v9.80 and their are bug fixes and other improvements in v9.80 that you will miss.

Note: 9.8 doesn't solve the problem with that example..

Solution:

Edit: Cross platform example based on B4XPages https://www.b4x.com/android/forum/threads/b4x-b4xpages-b4xdrawer.120246/ A class that implements a sliding menu. Unlike the nice jfeinstein SlidingMenu library the drawer covers the activity instead of pushing it. It is similar to the various...
