Rafael, I have the same problem, I´m trying to execute android test project, there is a step with the same code of line 3: baseApi.init(myDir, "eng");, in my test I, I believe my traineddata is ok, because the test execute a method to verify if file exists, and is ok, but, I get an error, from jni. Any help?
