Okhttp: Exception in thread "OkHttp Dispatcher" java.lang.NoSuchMethodError: okio.BufferedSource.getBuffer()Lokio/Buffer;

I use okhttpVersion = 3.14.1 and got the following error when I integrate with line bot library.

Exception in thread "OkHttp Dispatcher" java.lang.NoSuchMethodError: okio.BufferedSource.getBuffer()Lokio/Buffer;

The error because of can't resolve method getBuffer() from BufferedSource object. I think it should be source.buffer() not source.getBuffer()

The versions of okhttp, okio, and HttpLoggingInterceptor need to be same.

[bertytobing]

What is the latest version do you suggest for okhttp, okio, and HttpLoggingInterceptor? Thank you @TangHuaiZhe

[TangHuaiZhe]

Try the same ok version as in the line library

I have the same problem, How do you solve it?

@TangHuaiZhe good

In addition to @TangHuaiZhe's comment:

I had to exclude okio as a transitive dependency of retrofit:

implementation("com.squareup.retrofit2:retrofit:2.6.4") {
    exclude group: "com.squareup.okio", module: "okio"
}
