und hier ist mein

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 
     public void onClick(View view) { 
      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); 

} 

} 

Die Zahlen die Nachrichten von editTexts werden gesendet werden und sind das in sharedPreferences gespeichert. das Problem könnte aus dem gemeinsamen Präferenzen sein oder ist es und Ausgabe des Text-Manager

Answer 1

Ich glaube, Sie die destination address add angeben sollte eine if ... if(num1!="" || num2!="" || num3...) manager.sendText...
