问题
I need to read incoming SMS. I'm using BroadcastReceiver for this. It's working fine but when app is closed BroadcastReceiver also close.
Here is code that I'm using.
Manifest
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.READ_SMS"/>
<!--other code -->
<receiver android:name=".IncomingSms">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
IncomingSms
public class IncomingSms extends BroadcastReceiver {
// Get the object of SmsManager
final SmsManager sms = SmsManager.getDefault();
@Override
public void onReceive(Context context, Intent intent) {
// Retrieves a map of extended data from the intent.
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);
// Show Alert
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context,
"senderNum: "+ senderNum + ", message: " + message, duration);
toast.show();
} // end for loop
} // bundle is null
} catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" +e);
}
}
}
The code is working fine but want it to run even App is closed. I want to read SMS whenever it come. means this broadcast run lifetime never close until App uninstall. I think I need service for this but how can I do that, I'm new in android.
回答1:
Yo need to write IntentService for that, you can start such service in broadcast receiver, because broadcast reciever can not execute for long time.
