Unable to delete a row from database in android (sql query is empty after the where clause)

For some reason the sql query is not complete,

DELETE FROM activations WHERE smsArrivalTimeStamp =

The Exception

01-08 16:19:01.447: E/AndroidRuntime(4659): Caused by: android.database.sqlite.SQLiteException: near "=": syntax error (code 1): , while compiling: DELETE FROM activations WHERE smsArrivalTimeStamp =
01-08 16:19:01.447: E/AndroidRuntime(4659):     at android.database.sqlite.SQLiteConnection.nativePrepareStatement(Native Method)

The Code

public void deleteActivation(long timeStamp) {
        String selection = God.COLUMN_NAME_SMS_ARRIVAL_TIME_STAMP + " = ";
        String[] selectionArgs = { String.valueOf(timeStamp) };
        System.out.println("Selections Args "+ selectionArgs[0]) ;
        God.activationsDB.getWritableDatabase().delete(God.TABLE_ACTIVATIONS,
                selection, selectionArgs);
    }

The system.out is printing
