Android Question #AdditionalJar: guava-23.0.jar causes the compile to fail

[Bryan Joyce]

I have an app that uses Firebase notifications and needs to be able to send and receive notifications from B4A the way it did until Google changed their authentication method. I have followed Erel's example and it works fine to be able to send from B4J. I have attempted to use the same code and resources in B4A and I have run into a number of issues. If I add #AdditionalJar: guava-23.0.jar the project will not compile (error is below). If I comment it out, it will compile. The project attributes are

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

The libraries I am using are
B4XPages 1.12
Core 12.8
Firebase Analytics 3.01
Firebase Notifications 3.11
JSON 1.21
OkHTTP 1.50
OKHTTPUtils2 3.04
Phone 2.60
Runtime Permissions 1.2

Manifest is
<Code>
AddManifestText(
<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="34"/>
<supports-screens android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.LightTheme)
'End of default text.
CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)
CreateResourceFromFile(Macro, FirebaseAnalytics.Firebase)
CreateResourceFromFile(Macro, FirebaseAnalytics.FirebaseAnalytics)
CreateResourceFromFile(Macro, FirebaseNotifications.FirebaseNotifications)
</Code>

SDK Manager is up to date but I get an error "Error reading recommended items list". I don't think this is related because I was having the issue prior to seeing this.

Hopefully this is enough information and ideas are appreciated.

o be able to send and receive notifications from B4A

It is not possible to sen them from B4A anylonger

 

[Bryan Joyce]

Thanks for the reply. That is most disappointing, it completely breaks an app that was working for years. I will have to look for an alternative

 

[Erel]

Remove the guava reference and add this:

#AdditionalJar: com.google.guava:guava
#AdditionalJar: com.google.guava:listenablefuture

 

[Bryan Joyce]

Thanks Erel, it compiles now. It now crashes when I attempt to send a message with Firebase notifications. I can open a new question if you think it is not related.

Sending push messages from B4A

1. Download dependencies from: https://www.b4x.com/android/forum/threads/b4x-firebase-push-notifications-2023.148715/ 2. Download: https://repo1.maven.org/maven2/com/google/guava/failureaccess/1.0.2/failureaccess-1.0.2.jar Copy all jars to the additional libraries folder. 3. Add to main...

[Bryan Joyce]

Thanks Erel! I am able to send with a B4A app now! My app needs to send and receive and both are not working at the same time, I can do one or the other. Will getting tokens from the send code and receive code conflict? My code is above. I am going to experiment a little more on this.

No relation between the two features. For further discussion please start a new thread.
