API de Telefonia e SMS

A plataforma Android provê aplicações próprias para realizar chamadas telefônicas. Em amas ocasiões é necessário realizar chamadas através de nosso aplicativo. Isso pode facimente ser realizado através do uso se um Intent implícita com as ações apropriadas. Aléisso, podemos utilizar as classes PhoneStateListener e TelephonyManager de modoa monitorar as mudanças em alguns estados de telefonia do dispositivo.

- Objeto Intent - Usando uma ação para realizar uma chamada telefônica

É necessário usar a ação ACTION_CALL para ativar a funcionalidade de chamadas disponíveo Android.

Intent phoneIntent = new Intent(Intent.ACTION_CALL);

Também é possível usar a ação ACTION_DIAL, neste caso há a opção de modificar o número antes de realizar a chamada, ao invés de realizar a chamada diretamente.

- Objeto Intent - Passando dados para realizar a chamada

Para realizar uma chamada para um determinado número, por exemplo 91-000-000-0000, é necessário explicar [tel:] como a URI ára o método setData(), como demonstrado a segir:

phoneIntent.setData(Uri.parse("tel:91-000-000-0000"));

Exemplo Prático

#####MainActivity.java.

package br.com.fuctura.exemplochamada;

import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.support.v7.app.ActionBarActivity;import android.os.Bundle;import android.view.Menu;

import android.view.MenuItem;import android.view.View;import android.widget.Button;import android.widget.RadioButton;import android.widget.RadioGroup;import android.widget.Toast;

public class MainActivity extends Activity { Button b1;



@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); b1=(Button)findViewById(R.id.button); call(); }

private void call() { Intent in=new Intent(Intent.ACTION_CALL,Uri.parse("0000000000")); try{ startActivity(in); }

catch (android.content.ActivityNotFoundException ex){ Toast.makeText(getApplicationContext(),"A Activity não foi encontrada.",Toast.LENGTH_SHORT).show(); } }

@Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_main, menu);

return true; }

@Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml.

int id = item.getItemId();

//noinspection SimplifiableIfStatement if (id == R.id.action_settings) {

return true; } return super.onOptionsItemSelected(item); }}#####

>> Enviando SMS

No Android, é possível utilizar a API SmsManager ou a aplicação nativa do android para nviar um SMS.

- SmsManager API

SmsManager smsManager = SmsManager.getDefault();smsManager.sendTextMessage("00000000000", null, "mensagem", null, null);

- Através da aplicação nativa

Intent sendIntent = new Intent(Intent.ACTION_VIEW);sendIntent.putExtra("mensagem", "conteúdo padrão");sendIntent.setType("vnd.android-dir/mms-sms");startActivity(sendIntent);



E claro, para poder utilizar essas funcionalidades é necessário ter a permissão específca no arquivo de manifesto:

<uses-permission android:name="android.permission.SEND_SMS" />

Além dos métodos demonstrados anteriormente, há mais alguns métodos interessantes na clsse SmsManager:

------------------------------ ArrayList<String> divideMessage(String text)

This method divides a message text into several fragments, none bigger than themaximum SMS message size.

- static SmsManager getDefault()

This method is used to get the default instance of the SmsManager

- void sendDataMessage(String destinationAddress, String scAddress, short destinationPort, byte[] data, PendingIntent sentIntent, PendingIntent deliveryIntent)

This method is used to send a data based SMS to a specific application port.

- void sendMultipartTextMessage(String destinationAddress, String scAddress, ArrayList<String> parts, ArrayList<PendingIntent> sentIntents, ArrayList<PendingIntent> deliveryIntents)

Send a multi-part text based SMS.

- void sendTextMessage(String destinationAddress, String scAddress, String text,

PendingIntent sentIntent, PendingIntent deliveryIntent)

Send a text based SMS.--------------------------------

String mensagem = txtMessagem.getText().toString(); try {

SmsManager smsManager = SmsManager.getDefault(); smsManager.sendTextMessage(phoneNo, null, message, null, null); Toast.makeText(getApplicationContext(), "SMS sent.", Toast.LENGTH_LONG).show(); }

catch (Exception e) { Toast.makeText(getApplicationContext(), "SMS faild, please try again.", Toast.LENGTH_LONG).show(); e.printStackTrace();

} }

Para usar uma Intent para enviar a SMS chamando a aplicação nativa do Android é necessáio usar a ação ACTION_VIEW para inicializar o cliente instalado no dispositivo.

Intent smsIntent = new Intent(Intent.ACTION_VIEW);

É necessário especificar a URI smsto: no método setData() e o tipo de dado deve ser vnd.android-dir/mms-sms:

smsIntent.setData(Uri.parse("smsto:"));smsIntent.setType("vnd.android-dir/mms-sms");

- Objeto Intent - Usando um Extra para enviar a SMS

smsIntent.putExtra("endereço" , new String("0123456789;3393993300"));smsIntent.putExtra("mensagem" , "Mensagem para Maria.");
