Question

我有一个BroadcastReciever，它调用sms活动获取Gps协调并将其发送到另一个设备。问题是，无论何时我调用getGPSLocation，应用程序都会失败。如果我发表评论它就可以了。有一些位置导致应用程序失败，但我找不到它。请有人帮助找到问题。谢谢你的关注。

public class SMS extends AppCompatActivity {
private String myGPSLocation;
private LocationManager myLocationManager;
boolean issent = false;
String text = "your cordinates ";
SmsManager smsManager = SmsManager.getDefault();

  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //call message method pass getGPS function which returns string
    myLocationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);


    // Define a listener that responds to location updates
    LocationListener locationListener = new LocationListener() {
        public void onLocationChanged(Location location) {
            // Called when a new location is found by the network location provider.
            //makeUseOfNewLocation(location);
            myGPSLocation = location.toString();
        }

        public void onStatusChanged(String provider, int status, Bundle extras) {
        }

        public void onProviderEnabled(String provider) {
        }

        public void onProviderDisabled(String provider) {
        }
    };
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling
        //    ActivityCompat#requestPermissions
        // here to request the missing permissions, and then overriding
        //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
        //                                          int[] grantResults)
        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }
    myLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
    message(text + getGPSLocation());
}


private String getGPSLocation() {
    String cords;
    if (myGPSLocation == null) {

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return "PERMITED";
        }
        Location locationGPS = myLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        cords = locationGPS.toString();
        return  cords;
    }
    else {
        return myGPSLocation;
    }

}






public void message(String info)
{

    PendingIntent pi = PendingIntent.getActivity(this, 0,
            new Intent(this, SMS.class), 0);
    SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
    String num = settings.getString("phone_number", "");
    if(num != "") {
        smsManager.sendTextMessage(num, null, info, pi, null);
        issent = true;
        this.finish();
    } else { Toast.makeText(this, "Phone is not SET ", Toast.LENGTH_SHORT).show();   this.finish();}
    }
boolean isSent()
{
    return issent;
}

}

logcat的

试试这个，

交换这两行。在初始化导致NLP的 myLocationManager 之前，您正在调用getGPSLocation（）方法。

    message(text + getGPSLocation());
    myLocationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

到

    myLocationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

    message(text + getGPSLocation());

你可以再做一次检查在

private String getGPSLocation() {
    String cords;
    if (myGPSLocation == null) {

      if(myLocationManager != null){

    ....//your code

      }

    }

让Gps坐下并用Sms发送它
