Logout and Close all activities in Android

Login > HomePage ->Activity1 ->Activity2->Activity3

If once I have gone to Activity3 then from there to Home page. From there i am trying to logout. It is sending me back to the Login page but if I am pressing the back button of my phone it it showing all the previous activities. Please help me on how can we do this.

This is what i have tried 

logout.setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View arg0) {
        SharedPreferences myPrefs = getSharedPreferences("SelfTrip", MODE_PRIVATE);
        SharedPreferences.Editor editor = myPrefs.edit();
        editor.clear();
        editor.commit();
        Log.d(TAG, "Now log out and start the activity login");
        Intent loginPageIntent = new Intent(getApplicationContext(), LoginPage.class);
        loginPageIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
        loginPageIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(loginPageIntent);

    }
});

// check sharedPreferences in all activities
// when you press back button then it will close activity
@Override
protected void onResume() {
    super.onResume();
    int userId = sharedPreferences.getInt(Login.user_id, 0);

    if(userId==0){
        finish();
    }
}

You can use another way i.e adding activity in an arraylist of type activity and finish the activity you want from any other activity.

you can simply force the activity to NOT leave a history in your backstack. This can cause trouble, but should work fine as long as your activities are called linear.

Add the line with noHistory to the manifest:

<activity
        android:name="com.example.MainActivity"
        android:label="@string/app_name"           
        android:screenOrientation="portrait"

        android:noHistory="true" >
</activity>

Login activity needs to have android:launchMode="singleTop" in Manifest file. Here's the link for stack and back stack.

You also need to remove loginPageIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); as that will create a new task and put Login as root.
