Apps can anyone help on programming phone

[tweacle]

Hi there

Ive been told to do this on my phone:

First of all, you can listen for changes in the call state using a PhoneStateListener. You can register the listener in the TelephonyManager:


How do I get into it?

Thanks

It's not clear what your asking.

To what app does your question pertain?

Thinking about programming your own app in something like
... Java? If so, I don't think this is the right forum

moved to the android development forum

 

[out of ideas]

Yeah thats java code stuff. not something you can just access from your phone.

Yes, you can. Lots of apps out there use this TelephonyManager class. You will need to be able to build a basic android application along with basic Java knowledge.

Here is an example of how you could use this class:

First in your manifest you will need this permission:
[HIGH]
<uses-permission android:name="android.permission.READ_PHONE_STATE" />[/HIGH]

and a receiver like this:
[HIGH]
<receiver android:name=".PhoneServiceReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
[/HIGH]

Then you will need to classes (or one depending how you want to set everything up)


ServiceReceiver
[HIGH]
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;

public class ServiceReceiver extends BroadcastReceiver {

TelephonyManager telephony;

public void onReceive(android.content.Context context, Intent intent) {
CustomStateListener phoneListener = new CustomStateListener();
telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
}

public void onDestroy() {
telephony.listen(null, PhoneStateListener.LISTEN_NONE);
}

}
[/HIGH]

and

CustomStateListener
[HIGH]
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

public class CustomStateListener extends PhoneStateListener {

public static Boolean isRinging = false;

public void onCallStateChanged(int state, String incomingNumber) {

switch (state)
{
case TelephonyManager.CALL_STATE_IDLE:
Log.d("TEST", "Phone - IDLE");
isRinging = false;
break;

case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d("TEST", "Phone - OFFHOOK");
isRinging = false;
break;

case TelephonyManager.CALL_STATE_RINGING:
Log.d("TEST", "Phone - RINGING");
isRinging = true;
break;

}
}

}
[/HIGH]

Hope this helps you.. or someone.
