Android Question B4AGraphView - EdgeEffectCompat

[PhilipK]

Hi B4A

I've been using the B4AGraphview library for a long time now. Suddenly, a problem and can't find the solution on the internet.

Compiling and running my app or the B4AGraphview example provided, generates the error:

java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/widget/EdgeEffectCompat;

With hours passing and no sight of solving it, I've done a complete re-installation of Java, Android SDK and B4A as per instructions. Now running jdk1.8.0_251, B4A v9.80 and checked the Android SDK in B4A and unfortunately, no success:

Thanks in advance

Redownload AppCompat 4.0 ZIP.

It now includes a AndroidX Version too.

If that does not work i fear your SDK is incompatible.

To install a new SDK follow the installationinstructions carefully. 2 Zips to download and extract.

Hi DonManfred

Thanks for that.
Just installed library AppCompat 4.0 and re-started B4A.

Still generates an error:

** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **

Does the #region Project attributes look right?:

#ApplicationLabel: B4AGraphView Example
#VersionCode: 1

'SupportedOrientations possible values: unspecified, landscape or portrait.

The manifest:

[DonManfred]

Looks ok. I suggest to reinstall the SDK. Follow the instructions carefully and it will just work.

 

[PhilipK]

Arrgh, it hasn't worked:

** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
** Activity (main) Create, isFirst = false **
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (livedata) Create, isFirst = true **

The app starts and the crashes on selecting 'Live data'

 

[DonManfred]

Upload a small example project which shows the issue; i´ll try it with my System.

 

[PhilipK]

Just noticed the SDK manager in B4A looks in a folder ..AppData/Local/Android/SDK . I have been updating C:/Android/tools. Is this the issue? I should be updating the AppData path?

If you installed a new sdk you need to adapt the path in the ide to this new sdk. Sure.

 

[PhilipK]

Ok, The B4A SDK manager points me to :

https://developer.android.com/studio/index.html#command-tools

I downloaded and extracted 'commandlinetools-win-6200805_latest.zip' to the C:\Users\PhilipK\AppData\Local\Android\sdk\ folder to update the tools folder and now the SDK manager reports (sorry, it's better you see the result):

It's going bad to worse!

 

[DonManfred]

Download the SDK with the link provided here.

• You need to download two components, both of them do not require installation.
• Download Android SDK Command line tools
  Make sure to read and agree to the SDK license. Click on the Windows command line tools to see the license.
  Android Studio is not needed and will not be affected by the command line tools (which are always required).
• Unzip it in a folder such as C:\Android
  
  
• Download the required resources.
• Unzip in the same folder. It should look like this:
  
  

Any other download will not work.

 

[PhilipK]

Here's the app....

 

[DonManfred]

i´ll check later when i am at home.
Which libraries are you using in the app?

 

[DonManfred]

Here's the app....

It is incomplete. There are missing classes

Use File->Export as ZIP to export a project.

Your zip does contins a appcompat 2 zip which is outdated since YEARS. You are NOT using this old version, right?

 

[PhilipK]

Here using File Export:

 

[PhilipK]

The library manager has AppCompat v4.0 checked

 

[DonManfred]

The library manager has AppCompat v4.0 checked

i was just wiondering about the appcompat 2 zip

 

[PhilipK]

I've seen that there are AppCompat jar and xml in the additional libraries folder which I have removed. I extracted the AppCompat4 lib in the C:/anywhere../B4A/library folder and it still fails.

 

[DonManfred]

I ran your example.

It does not work here too. I guess the problem is inside the Graphview jar which, it seems, it not AndroidX compatible.

I then jetified all libraries. and tried again.

C:/anywhere../B4A/library

This is the WRONG folder! It must be placed into the additional library folder. NEVER in the internal

Run the jetifier tool and try again.

After i jetified Graphview library your example does work

 

[PhilipK]

Ok, I put the AppCompats in the additional library folder , removed them from the internal folder, used the Jetify tool which opened a window saying the AppCompat will be jetified. Run it again and failed. Can't see how you Jetify the Graphview?

 

[DonManfred]

Can't see how you Jetify the Graphview?

Graphview must be inside the additional lib folder too! The jetifier tool should have listed it too. At least this worked for me

Again: Download appcompat 4.0 and use the files in this zip. NO NEED to jetifier AppCpmpat
