Android phone built-in back button












0














I have an activity with two fragments, each fragment has a back button to the previous activity/fragment. Both the back buttons on the fragments work properly. However when i run the app on my android phone and i use the built-in back button to navigate to the previous activity, it displays a blank activity and then when i press the built-in back button again only then does it navigate to the previous activity. The problem is clearly the back burton than built in.Is there a way to solve this???

          There is a method in the Activity called onBackPressed() which is called when the device back button is pressed. If you want to control what happens on back press just override it. To remove default onBackPressed action you need to remove the call to super.onBackPressed() and then you control what happens when back button is pressed. 



          @Override
          
    public void onBackPressed() {
          
        //super.onBackPressed();
          
        // do something here
          
        // or perhaps nothing at all
          
    }

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
