Android: Button not opening new Activity?

Question

Within my application I have set up intents to open specific activities from a Menu screen.

Each Button opens a new Activity. They are all working as intented apart from One button which doesnt do anything when clicked.

What am I doing wrong? I have checked:

-manifest

-xml

-both activities

and I cannot see a problem. Also there is no logcat error.

Full menu activity:

package com.example.brianapp;

import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.content.Intent;
import android.os.Bundle;
import android.view.View.OnClickListener;

public class Search extends ActionBarActivity implements View.OnClickListener {

    TextView instruction;
    Button date;
    Button game;
    Button med;
    Button att;
    Button score;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.searchhome);

        // setting up vars
        instruction = (TextView) findViewById(R.id.tvSearchHome);
        date = (Button) findViewById(R.id.btnSearchHomeDate);
        game = (Button) findViewById(R.id.btnSearchHomeGame);
        med = (Button) findViewById(R.id.btnSearchHomeMedValues);
        att = (Button) findViewById(R.id.btnSearchHomeAttValues);
        game = (Button) findViewById(R.id.btnSearchHomeScore);

        // set on click listeners for the buttons
        date.setOnClickListener(this);
        game.setOnClickListener(this);
        med.setOnClickListener(this);
        att.setOnClickListener(this);
        game.setOnClickListener(this);

    }

    public void onClick(View v) {

        switch (v.getId()) {

        case R.id.btnSearchHomeDate:

            Intent openDateSearch = new Intent(
                    "com.example.brianapp.SearchDate");
            // Start activity
            startActivity(openDateSearch);

            break;

        case R.id.btnSearchHomeGame:

            // change this to make sure it opens the med screen
            Intent openGameSearch = new Intent(
                                "com.example.brianapp.SearchGame");
            // Start activity
            startActivity(openGameSearch);

            break;  

        case R.id.btnSearchHomeMedValues:

            // change this to make sure it opens the med screen
            Intent openMedSearch = new Intent(
                    "com.example.brianapp.MeditationSearchHome");
            // Start activity
            startActivity(openMedSearch);

            break;

        case R.id.btnSearchHomeAttValues:

            // change this to make sure it opens the med screen
            Intent openAttSearch = new Intent("com.example.brianapp.AttentionSearchHome");
            // Start activity
            startActivity(openAttSearch);
            break;

        case R.id.btnSearchHomeScore:

            // change this to make sure it opens the med screen
            Intent openScoreSearch = new Intent(
                    "com.example.brianapp.SearchScore");
            // Start activity
            startActivity(openScoreSearch);

            break;

        }// switch end

    }

}

Specific Case note working:

case R.id.btnSearchHomeGame:

                // change this to make sure it opens the med screen
                Intent openGameSearch = new Intent(
                                    "com.example.brianapp.SearchGame");
                // Start activity
                startActivity(openGameSearch);

                break;

The corresponding parts of Manifest :

<activity

            android:label="@string/title_activity_search" >
            <intent-filter>

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>

Answer 1

you override the ref of game button:

 game = (Button) findViewById(R.id.btnSearchHomeGame);

 game = (Button) findViewById(R.id.btnSearchHomeScore);

you should change it to :

 game = (Button) findViewById(R.id.btnSearchHomeGame);

 score= (Button) findViewById(R.id.btnSearchHomeScore);

Answer 2

Change this:

Intent openGameSearch = new Intent("com.example.brianapp.SearchGame");

to this:

Intent openGameSearch = new Intent(this,
                                   com.example.brianapp.SearchGame.class);
