I need to call an application already installed on my phone once I receive an SMS from a certain number.
All the code in this application is ready, but I do not know how to call it from that message.
Should I use Intent or something similar?
Using BroadcastReceiver , you can intercept incoming messages on the device.
First you will need the following permission on your AndroidManifest.xml , in this case I put it to increase the priority this will help if you have another application (third party) that captures SMS, so it will have privilege when receiving: / p>
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<receiver android:name="com.example.smsinterceptor.MessageReceiver" android:exported="true">
<intent-filter android:priority="999" >
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
BroadcastReceiver MessageReceiver.java , here in receiver I get the message and all the details through the extras. Just be careful that if your message is composed of more than one SMS you will have to deal; in the code below I only deal with a message. Also, after detecting the message I want I use abortBroadcast() , this will prevent other applications from capturing this same message (provided the priority is ok in the manifest ):
public class MessageReceiver extends BroadcastReceiver {
private String TAG = MessageReceiver.class.getSimpleName();
private String NUMBER_FILTER = "3784";
public void onReceive(Context context, Intent intent) {
Log.e(TAG, "Receiver activated");
Bundle extraContent = intent.getExtras();
Object[] messagePdus = (Object[]) extraContent.get("pdus");
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) messagePdus[0]);
if (smsMessage.getOriginatingAddress().endsWith(NUMBER_FILTER)) {
Log.e(TAG, "Message intercepted: "+ smsMessage.getMessageBody());
abortBroadcast();
}
}
}
