Take a look at this CallLog class. All you need is to query the phone for any calls then extract missed one (оr do this when you are querying the phone, in the selection arguments). The same applies for the messages. SMS are stored in the Content provider under "content://sms/"

Then just get the count of rows in the Cursor that is return by the query. :)

I hope this helps.

For missed calls:

String[] projection = {
    CallLog.Calls.CACHED_NAME,
    CallLog.Calls.CACHED_NUMBER_LABEL,
    CallLog.Calls.TYPE
};
String where = CallLog.Calls.TYPE + "=" + CallLog.Calls.MISSED_TYPE;          
Cursor c = this.getContentResolver().query(
    CallLog.Calls.CONTENT_URI,
    selection,
    where,
    null,
    null
);
c.moveToFirst();    
Log.d("CALL", ""+c.getCount()); //do some other operation
if (c.getCount() == SOME_VALUE_TO_START_APP_ONE) //...etc etc

In the where clause you set condition for selection of data. In our case we need everything which type equals CallLog.Calls.MISSED_TYPE. We select project the Name of the caller and his number, ofcourse you can specify more information to be queried like type of number like mobile, home, work. The expression is equivalent to SQL query, something like: SELECT CACHED_NAME, CACHED_NUMBER_LABEL, TYPE FROM CONTENT_URI WHERE TYPE=MISSED_TYPE

This requires permissions to be added to the Manifest

<uses-permission android:name="android.permission.READ_LOGS"></uses-permission>

<uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>

For querying SMS ContentProvider:

Uri sms_content = Uri.parse("content://sms");
Cursor c = this.getContentResolver().query(sms_content, null,null, null, null);
c.moveToFirst();
Log.d("SMS COUNT", "" + c.getCount()); //do some other operation
// Here proceed with the what you wanted
if (c.getCount() == SOME_VALUE_TO_START_APP_ONE)//...etc etc

You can go deeper in the content tree like specifying the type of sms, like: content://sms/sent or content://sms/inbox and add projection and selection for the second argument of the query() method like, name, person, status of the message (like the Calls example).

This requires permission:

<uses-permission android:name="android.permission.READ_SMS"></uses-permission>
