Answer 1

i have solved by adding the following in on create method

if ((getIntent().getFlags() & Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT) != 0) { 
    // Activity was brought to front and not created, 
    // Thus finishing this will get us to the last viewed activity 
    finish(); 
    return; 
}
