这是我的

MainActivity.java

package com.android.beez.help2;

import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.location.LocationManager;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {
Button button;
SharedPreferences sharedPreferences;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    buttonInit();
    Button setupMa = (Button) findViewById(R.id.setupMA);
    setupMa.setOnClickListener(new View.OnClickListener() {
        @Override

            Intent a = new Intent(MainActivity.this,Setup.class);
            startActivity(a);
        }
    });


    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            loadCredit();
            sendSms();

        }
    });
}


protected void sendSms() {

    spInit();

    String number1 = sharedPreferences.getString("first", "");
    String number2 = sharedPreferences.getString("second", "");
    String number3 = sharedPreferences.getString("third", "");
    String name = sharedPreferences.getString("name", "");
    String text = "Help, this is " + name + ", if you are reading this I am in trouble please help me" +
            " Iam located at " + "http://www.google.com/maps/place/"+GPSTracker.latitude+","+GPSTracker.longitude+ " " +
            "" +
            "" +
            "-Sent via the Emergency App";

    SmsManager manager = SmsManager.getDefault();
    manager.sendTextMessage(number1, null, text, null, null);
    manager.sendTextMessage(number2, null, text, null, null);
    manager.sendTextMessage(number3, null, text, null, null);



    boolean isFirstRun = getSharedPreferences("PREFERENCE", MODE_PRIVATE)
            .getBoolean("isFirstRun", true);

    if (isFirstRun) {
        Intent launchSetups = new Intent(MainActivity.this, Setup.class);
        startActivity(launchSetups);


        }
    }

protected void loadCredit() {

    spInit();

    String creditLine = sharedPreferences.getString("dialLoadSp","");

    Uri number = Uri.parse("tel:"+creditLine);
    Intent callIntent = new Intent(Intent.ACTION_DIAL, number);
    startActivity(callIntent);
}

public void buttonInit() {
     button = (Button) findViewById(R.id.button_main);
}
public void spInit() {
    sharedPreferences = MainActivity.this.getSharedPreferences("com.android.beez.help2",MODE_PRIVATE);

}

}

发送消息的数字来自editTexts，并存储在sharedPreferences中。问题可能来自共享偏好，还是文本管理器的问题

Answer 1

我认为您应该指定destination address添加if ... if(num1!="" || num2!="" || num3...) manager.sendText...

Answer 2

哦，我知道这一个:)希望我不迟到。

如果IllegalArgumentException或destinationAddress为空，则抛出

text。在您的情况下，您有这个String number1 = sharedPreferences.getString("first", "");，这意味着您的number1在应用程序首次运行时为空，因此您会收到该异常。另外，您在这里没有提供完整的代码，而是在其中说数字将由编辑文本填充。
