How Android Sets the cell broadcast default channel (50 and 60 and supports dual SIM) _android

Requires the default channel 50 and 60 to be set and a dual SIM card is supported.

Add code to the Phoneapp.java file:

At the beginning of the file, import the package:

Copy Code code as follows:

Import Android.provider.Telephony;
Import Com.android.internal.telephony.gsm.SmsBroadcastConfigInfo;
Import android.content.ContentValues;
Import Android.database.Cursor;

2. Add the variable at the beginning of the file:

Copy Code code as follows:

Private final Broadcastreceiver msmsreadyreceiver = new Smsreadybroadcastreceiver ();
private static final int message_set_state = 33;
private static final int message_set_config = 32;
private static final String keyID = "_id";
Private static final String name = "Name";
Private static final String number = "Number";
Private static final String enable = "Enable";
private static final Uri Channel_uri = Uri.parse ("Content://cb/channel");
private static final Uri Channel_uri1 = Uri.parse ("Content://cb/channel1");

3. Add Case in Mhandeler:

Copy Code code as follows:

Case Message_set_state:
Handlesetstateresponse (msg);
Break

4. Register the Cellbroadcastrecivier in the OnCreate function:

Copy Code code as follows:

Intentfilter smsreadyintentfilter = new Intentfilter ("Android.provider.Telephony.SMS_STATE_CHANGED");
Registerreceiver (Msmsreadyreceiver,smsreadyintentfilter);

5. Add functions to the class:

Copy Code code as follows:

Private class Smsreadybroadcastreceiver extends Broadcastreceiver {
@Override
public void OnReceive (context context, Intent Intent) {
LOG.E ("KPP", "Sms ready!!");
String action = Intent.getaction ();
LOG.E ("KPP", "Sms Ready action =" +action);
if (Action.equals ("Android.provider.Telephony.SMS_STATE_CHANGED")) {
int extra = Intent.getintextra ("Simid", 0);
Boolean isready = Intent.getbooleanextra ("Ready", false);
LOG.E ("KPP", "Sms Ready extra =" +extra);
LOG.E ("KPP", "Sms Ready isready =" +isready);
if (!isready) {
Return
}
Message msg;
msg = Mhandler.obtainmessage (message_set_state, Extra, message_set_state,null);

if (Featureoption.mtk_gemini_support = = True)
{
((geminiphone) phone). Activatecellbroadcastsmsgemini (0,msg, extra);
}
Else
{
Phone.activatecellbroadcastsms (0,MSG);
}
}
}
}

int simid = MSG.ARG1;
if (msg.arg2 = = message_set_state) {
AsyncResult ar = (asyncresult) msg.obj;

LOG.I (Log_tag, "Handlesetstateresponse,ar is null");
Return
}
if (ar.exception!= null) {
if (DBG)
LOG.D (Log_tag, "handlesetstateresponse:ar.exception=" + ar.exception);
} else {
LOG.I (Log_tag, "Handlesetstateresponse:re get OK");

Addcustomchanneltolist (phoneconstants.gemini_sim_2, "Channel1", 50);
Addcustomchanneltolist (phoneconstants.gemini_sim_2, "Channel2", 60);
}
}
}
