Can't find field [useDefaultMuteStories] with signature [Z]

[adrianbartyczak]

I built a new libtdjni.so library on Debian 12, and I get a new error (which I wasn't getting on Debian 11).

FATAL ERROR in native method: Can't find field [useDefaultMuteStories] with signature [Z] at org.drinkless.tdlib.Client.nativeClientReceive(Native Method) at org.drinkless.tdlib.Client.access$000(Client.java:15) at org.drinkless.tdlib.Client$ResponseReceiver.run(Client.java:148) at java.lang.Thread.run(java.base@11.0.18/Thread.java:829)

Anyone know what this means? (I'm a Java developer, not a C++ developer). Thanks!

It means that you have incompatible versions of libtdjni.so and TdApi.java from different TDLib versions.

[adrianbartyczak]

Oh, I do see the tdlib library in my libs folder. I have it under the name "tdlib-java-src.jar". This is definitely the library that's mismatching.

So when I built the libtdjni.so file, I deleted everything else. I didn't know I was suppose to get the tdlib jar also.

But now when I build Tdlib, I for some reason get the following error:

Did something change in the build?

[levlam]

The Java example wasn't updated to the latest TDLib version. I have just pushed a fix for this.

[adrianbartyczak]

That worked. Thanks, but now when I build the Java program, I get a new error:

FATAL ERROR in native method: Can't find field [isBlocked] with signature [Z]

I'm pretty sure I recreated the tdlib source jar correctly. I noticed all the Java class files are in "tdlib/bin/org/drinkless/tdlib". So I basically packaged them in a jar.

[levlam]

You have libtdjni.so from an old TDLib version. The latest TDLib has no fields named isBlocked.

[adrianbartyczak]

Oh, you were right. I copied it to my projects libs folder, but forgot to copy it to /usr/lib/x86_64-linux-gnu/jni.

You have helped me a lot. Thanks!
