我在Android Studio上使用IBM Watson Speech to Text API时遇到了一些问题。我遵循https://github.com/watson-developer-cloud/java-sdk/tree/develop/speech-to-text的说明。 这是我的MainActivity代码：什么是Android Studio上的java.lang.ExceptionInInitializerError和java.lang.IllegalArgumentException？
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.w("debug_prog", "[+] Start");
SpeechToText service = new SpeechToText("cff16fe4-6a27-4289-a343-a394e1c94c2x", "XStw1ieErTkx");
if(service == null){
Log.w("debug_prog", "[-] Service is null");
}
Log.w("debug_prog", "[+] Object Created");
File audio = new File("src/test/resources/audio_001.wav");
Log.w("debug_prog", "[+] Audio: " + String.valueOf(audio));
SpeechResults transcript = service.recognize(audio).execute();
Log.w("debug_prog", "[+] Result: " + String.valueOf(transcript));
}
}
但是当我编上Android手机的代码（API 22）我得到了一些错误是这样的：

这个错误发生时我创建SpeechToText对象，请帮助，谢谢:)
