Java?

Whats about implement the same bot in Java?

[Simon-Laux]

good idea, but unfortunately the java bindings are not standalone, they are part of the android client. so this could be a bit tricky.

the java bindings are pretty separated, though. they are in the folder https://github.com/deltachat/deltachat-android/tree/master/src/com/b44t/messenger

@EchedeyLR so, if you want to push this forward, you can copy this folder (together with the jni part) and use it. or just use the whole deltachat-android as a subproject. of course, i expect some things to be adapted. also a "high-level" api missing.

if there are actual bots in java, at some point, we can think over to separate this, however, this comes at costs, so the advantages and disadvantages should be weighted carefully.

Thank you. I will check. As I never tried to mount a bot before I expected an example in the language I can use and try to extend from it.

The following imports depend on android / the android ui code:

DcEventCenter.java:
import org.thoughtcrime.securesms.util.Util;

DcChatlist.java:
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;

DcContact.java:
import android.graphics.Color;
import android.util.Log;

DcContext.java:
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;

DcMsg.java:
import android.util.Log;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import org.thoughtcrime.securesms.connect.ApplicationDcContext;

@Simon-Laux thanks for the list, i made a pr removing these dependencies, deltachat/deltachat-android#1825

https://github.com/angelo-fuchs/dc-jni-playground is the attempt to make the java bindings standalone as a maven package

With deltachat/deltachat-android#2976 merged we still have Android-related hack
https://github.com/deltachat/deltachat-android/blob/430c15861abf9fa64fe5708843eaa5a3570f4bdf/jni/dc_wrapper.c#L10-L58

It provides fallback implementations for getauxval and recvmmsg functions which don't exist in NDK version used to build Android currently.

Also need to move
https://github.com/deltachat/deltachat-android/tree/430c15861abf9fa64fe5708843eaa5a3570f4bdf/src/com/b44t/messenger
into a separate module. util/concurrent/SettableFuture.java and probably ListenableFuture.java comes from Signal code, that would need proper annotation and the whole package would be GPLv3+ not MPL like the core then.
