Android checkbox checked in one activity and then button appears in another activity

The question says it all. Imagine there are 2 activity's, 'Activity A' and 'Activity B'.'Activity A' holds a checkbox when its checked a button should show on 'Activity B' when its unchecked the button should hide on 'Activity B'

below is the main activity

public class MainActivity extends ActionBarActivity {

private BubblesManager bubblesManager;
private boolean isCheckedValue;


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

initializeBubblesManager();


final Button add = (Button) findViewById(R.id.add);
add.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
addNewBubble();
add.setEnabled(false);
}
});

CheckBox checkBox = (CheckBox)findViewById(R.id.add_fb);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

isCheckedValue = isChecked;

Intent intent = new Intent(MainActivity.this, PopUpWindow.class);
intent.putExtra("yourBoolName", isCheckedValue );


}
});



}
private void addNewBubble() {
BubbleLayout bubbleView = (BubbleLayout)LayoutInflater.from(MainActivity.this).inflate(R.layout.bubble_layout, null);
bubbleView.setOnBubbleRemoveListener(new BubbleLayout.OnBubbleRemoveListener() {
@Override
public void onBubbleRemoved(BubbleLayout bubble) {
finish();
System.exit(0);
}
});
bubbleView.setOnBubbleClickListener(new BubbleLayout.OnBubbleClickListener() {

@Override
public void onBubbleClick(BubbleLayout bubble) {
Intent in = new Intent(MainActivity.this, PopUpWindow.class);
startActivity(in);
}
});
bubbleView.setShouldStickToWall(true);
bubblesManager.addBubble(bubbleView, 60, 20);
}


Below is the next activity aka 'activity B'

public class PopUpWindow extends Activity {

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


DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);

int width = dm.widthPixels;
int height = dm.heightPixels;

getWindow().setLayout((int)(width*.8),(int)(height*.6));

Boolean yourBool = getIntent().getBooleanExtra("yourBoolName",false);
Button fbbutton1 = (Button)findViewById(R.id.fbbutton1);
if(yourBool){
//For Displaying Button
fbbutton1.setVisibility(View.VISIBLE);
}


}


Below is the XML code for the button I want show when checkbox is clicked

<Button
android:visibility="gone"
android:id="@+id/fbbutton1"
android:onClick="button"
android:background="@drawable/fbcircle"
android:layout_width="50dp"
android:layout_height="50dp" />
