__android_log_print打印信息乱码(非中文)

java代码：



public class SipMessage {



	public String serverIp;

	public String username;

	public String password;

}

在activity上有三个输入框分别对应上边三个属性，输入(英文)完成后，点击一个按钮，触发native方法register()



JNIEXPORT void JNICALL Java_com_sxsexe_study_SipUIActivity_register

(JNIEnv *env, jobject obj, jobject message)

  {

      //printf("!!!!!!!!!!!!!!!!!!!  -----------------------!!!!!!!!!!!!!!!!!!!!!!!!!!!\n");

      LOGD("Register method in C has been invoked-----");



      jclass clazz = (*env)->GetObjectClass(env, message);

      jfieldID field_server_ip = (*env)->GetFieldID(env, clazz, "serverIp", "Ljava/lang/String;");

      jfieldID field_username = (*env)->GetFieldID(env, clazz, "username", "Ljava/lang/String;");

      jfieldID field_password = (*env)->GetFieldID(env, clazz, "password", "Ljava/lang/String;");



      jstring str_server_ip = (*env)->GetObjectField(env, message, field_server_ip);

      jstring str_username = (*env)->GetObjectField(env, message, field_username);

      jstring str_password = (*env)->GetObjectField(env, message, field_password);



      __android_log_print(ANDROID_LOG_DEBUG,"sever ip","serveri ip is %s",str_server_ip);

      __android_log_print(ANDROID_LOG_DEBUG,"username","username is %s",str_username);

      __android_log_print(ANDROID_LOG_DEBUG,"password","password is %s",str_password);



  }

结果输出显示成小方块了，如下：
03-01 08:03:58.502: D/sever ip(925): serveri ip is ??
03-01 08:03:58.502: D/username(925): username is ??
03-01 08:03:58.513: D/password(925): password is ??

在eclipse的logcat窗口中就显示成了小方块儿

有没有人可以解释一下是什么情况

注：操作系统是中文的，Eclipse下编码格式为UTF-8
