Null pointer exception in load library of webrtc-java #38

Closed RaniRaven closed 2 years ago

RaniRaven commented 2 years ago

For some reason the code fails upon getting NullPointerException when trying to load the webrtc-java.dll from the jar. This is while calling the NativeClassLoader. By the looks ]of the code, it seems like this thoing made a lot of problems before, a I cannot understand the need for all the TempPath inside.

Did anyone else tackled with this issue ?

Since the native libraries are packaged into the jar-files, they need to be extracted to the filesystem. The target directory is the temp folder.

If you haven't, create a module-info.java within your project and import (requires webrtc.java;). This should work.

See this issue if you are using IDEA.

I have solved this issue, it seems that in IdeaJ project one needs to add the native jar as module dependency before anything will work there. Thanx.

Hi, how to use the gradle jar on windows or linux without adding fmodule-info.java in IntelliJ IDEA，load error： tmp file： C:\Users\ADMINI~1\AppData\Local\Temp\webrtc-java2765647831398423105.dll

Caused by: java.lang.RuntimeException: Load library 'webrtc-java' failed

then lack the webrtc-java-0.3.0-windows-x86_64.jar compared with maven.

And then when use maven project, it's ok to run this jar, but error happened while running List<AudioDevice> captureDevices = MediaDevices.getAudioCaptureDevices(); java.lang.Error: MMF: Create device enumerator failed CoInitialize has not been called.`
