Question

（这是我的第一支队伍）在尝试编译我的代码并将结果放在Driver Station上时，在点击Play按钮后会出现一个＆＃34; Module Not Specified＆＃34;错误和结果代码未编译，操作模式随后不在驱动程序站上。我们现在使用Android Studio 3.0版（之前的版本已过时）。在以前的时间里，我们没有模块的这个错误。是否有人能够解释模块的概念以及如何添加模块以使此错误停止？我自己对使用Android Studio进行软件开发很新。虽然我不相信代码是错误，但我会为了上下文而提供它。任何帮助表示赞赏：D

import com.qualcomm.robotcore.eventloop.opmode.OpMode;
import com.qualcomm.robotcore.eventloop.opmode.TeleOp;
import com.qualcomm.robotcore.hardware.DcMotor;
import org.firstinspires.ftc.robotcore.external.Telemetry;

@TeleOp(name="AutoDrive", group="TankDrive")
public class AutoDrive extends OpMode 
{
    private DcMotor leftFrontMotor = null;
    private DcMotor leftBackMotor = null;
    private DcMotor rightFrontMotor = null;
    private DcMotor rightBackMotor = null;
    boolean sent;
    private int driveTime;
    public void init()
    {

        leftFrontMotor = hardwareMap.dcMotor.get("leftFront"); //Get motor objects, store them in corresponding reference variables
        rightFrontMotor = hardwareMap.dcMotor.get("rightFront");

        leftFrontMotor.setPower(0);
        rightFrontMotor.setPower(0);



        driveTime = 3000 // Robot will take 3 seconds with current weight to drive to safe zone
        Telemetry.addLine("Hardware variables successfully instantiated");
        sent = Telemetry.update();
    }

    public void start()
    {

        long limit = System.currentTimeMillis() + driveTime;

        while(System.currentTimeMillis() < limit) //drive in straight line for limit seconds
            drive();

        Telemetry.addLine("Stopping..");
        sent = Telemetry.update();
    }

    public void loop() {}

    public void stop() 
    {

        leftFrontMotor.setPower(0);
        rightFrontMotor.setPower(0);
        Telemetry.addLine("Robot successfully stopped.");
        sent = Telemetry.update();

    }
    private void drive()
    {
        leftFrontMotor.setPower(1);

        rightFrontMotor.setPower(1);

    }
}

Answer 1

Telemetry.addLine("Hardware variables successfully instantiated");
sent = Telemetry.update();

应该是

telemetry.addLine("Hardware variables successfully instantiated");
sent = telemetry.update();

小写时，您将在OpMode中引用遥测对象（这是您想要的）。 addLine和update方法不是静态的，因此您无法通过Telemetry类调用它们。

Answer 2

        leftFrontMotor = hardwareMap.dcMotor.get("leftFront"); //Get motor objects, store them in corresponding reference variables
    rightFrontMotor = hardwareMap.dcMotor.get("rightFront");

应该是

        leftFrontMotor = hardwareMap.DcMotor.get("leftFront"); //Get motor objects, store them in corresponding reference variables
    rightFrontMotor = hardwareMap.DcMotor.get("rightFront");
