I am trying to build an application where the user can send his/her location to the stored phone numbers in a sqlitedatabase. I tested the application where the user can send the location as a text message to just one phone number and it worked but now when I try to create a list of numbers and pass it as a parameter in sendTextMessage method of smsManager the location as a text message is not sent. I have tried out the given code below so far,
Code
public class Gps4Activity extends AppCompatActivity implements
GoogleApiClient.OnConnectionFailedListener {
private static final String LOG_TAG = "PlacesAPIActivity";
private static final int GOOGLE_API_CLIENT_ID = 0;
private GoogleApiClient mGoogleApiClient;
private static final int PERMISSION_REQUEST_CODE = 100;
private static final int MY_PERMISSIONS_REQUEST_SEND_SMS =0 ;
private TextView display;
private Button location_button,contacts_button;
//String number="xxxxxxxxxx";
ArrayList<String> numbers;
SQLiteDatabase db;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gps4);
numbers=new ArrayList<>();
db = new UserDatabase(this).getReadableDatabase();
location_button=(Button)findViewById(R.id.show_button);
contacts_button=(Button)findViewById(R.id.view_button);
display=(TextView)findViewById(R.id.location_textview);
mGoogleApiClient = new GoogleApiClient.Builder(Gps4Activity.this)
.addApi(Places.PLACE_DETECTION_API)
.enableAutoManage(this, GOOGLE_API_CLIENT_ID, this)
.build();
location_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (mGoogleApiClient.isConnected()) {
if (ActivityCompat.checkSelfPermission(Gps4Activity.this,
android.Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(Gps4Activity.this,
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
PERMISSION_REQUEST_CODE);
ActivityCompat.requestPermissions(Gps4Activity.this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
callPlaceDetectionApi();
}
});
contacts_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent=new Intent(Gps4Activity.this,DetailsActivity.class);
startActivity(intent);
}
});
}
public ArrayList<String> getContacts(){
Cursor cursor=db.rawQuery("SELECT * FROM "+UserDatabase.TABLE_NAME,null);
while (cursor.moveToNext()){
String contact=cursor.getString(cursor.getColumnIndex(UserDatabase.NUMBER));
numbers.add(contact);
}
return numbers;
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
Log.e(LOG_TAG, "Google Places API connection failed with error code: "
+ connectionResult.getErrorCode());
Toast.makeText(this,
"Google Places API connection failed with error code:" +
connectionResult.getErrorCode(),
Toast.LENGTH_LONG).show();
}
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
callPlaceDetectionApi();
} else {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.", Toast.LENGTH_LONG).show();
return;
}
break;
}
}
private void callPlaceDetectionApi() throws SecurityException {
PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi
.getCurrentPlace(mGoogleApiClient, null);
result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
@Override
public void onResult(PlaceLikelihoodBuffer likelyPlaces) {
for (PlaceLikelihood placeLikelihood : likelyPlaces) {
Log.i(LOG_TAG, String.format("Place '%s' with " +
"likelihood: %g",
placeLikelihood.getPlace().getName(),
placeLikelihood.getLikelihood()));
display.setText(placeLikelihood.getPlace().getAddress().toString());
messageSending(placeLikelihood.getPlace().getAddress().toString());
break;
}
likelyPlaces.release();
}
});
}
public void messageSending(String message){
SmsManager smsManager = SmsManager.getDefault();
// smsManager.sendTextMessage(number, null, message, null, null);
getContacts();
smsManager.sendTextMessage(String.valueOf(numbers),null,message,null,null);
Toast.makeText(getApplicationContext(), "SMS sent."+String.valueOf(numbers),
Toast.LENGTH_LONG).show();
}
}
The commented lines are the ones when I tried to test the application with just one phone number. Also, suppose initially there is just one phone number in sqlitedatabase , as many times I click the location_button that many times the arraylist grows it's size. For example , initially if the arraylist has elements [xxxxxx] next time I click the location_button the arraylist will now have [xxxxxx,xxxxxx].
Can anyone help me solving this issue?
Since the sendTextMessage() method only can take one number at a time, you need to execute this method for each number in the list.
That being said you should 'loop' through that List. Like this:
for (String number : numbers) {
smsManager.sendTextMessage(numbers, null, message, null, null);
}
What it basically is saying is:
"Allright, let's take number one, sendTextMessage to number one, and I will keep doing this until I am done."
