これを行うために私が使用するものは次のとおりです。
マニフェスト：
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<!--This part is inside the application-->
<receiver android:name=".CallReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>

次に、それを使用するには、それからクラスを派生させ、気になる呼び出しタイプに関係なく、いくつかの簡単な関数を実装します。
public class CallReceiver extends PhonecallReceiver {
@Override
protected void onIncomingCallReceived(Context ctx, String number, Date start)
{
//
}
@Override
protected void onIncomingCallAnswered(Context ctx, String number, Date start)
{
//
}
@Override
protected void onIncomingCallEnded(Context ctx, String number, Date start, Date end)
{
//
}
@Override
protected void onOutgoingCallStarted(Context ctx, String number, Date start)
{
//
}
@Override
protected void onOutgoingCallEnded(Context ctx, String number, Date start, Date end)
{
//
}
@Override
protected void onMissedCall(Context ctx, String number, Date start)
{
//
}
}
