Reading Android application version name and version code defined in the Manifest file programatically in android              /**      * Method to Fetch Application Name as Defined in Manifest File      * @returns String      */     public String getVersionName(){         String versionName = "";         try {                 versionName = getPackageManager().getPackageInfo(getPackageName(), 0).versionName;         } catch (Exception e) {             e.printStackTrace();         }         return versionName;     }         /**      * Method to Fetch Application Number as Defined in Manifest File      * @returns String      */     public int getVersionNumber(){         int versionNumber = 0;         try {             versionNumber = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;         } catch (Exception e) {             e.printStackTrace();         }         return versionNumber;     }

Add different dimens.xml files to support different font sizes for all supporting devices in your application.. First create different folders as below, Under res folder create folders as , res/values/dimens.xml(default) res/values-ldpi/dimens.xml (for ldpi devices) res/values-mdpi/dimens.xml res/values-hdpi/dimens.xml res/values-xhdpi/dimens.xml   res/values-xxhdpi/dimens.xml For Tablets , res/values-sw600dp/dimens.xml (600*1024) res/values-sw720dp-land/dimens.xml (800*1280) Now Update dimens.xml for defining font sizes dimens.xml file should have text size defined for all labels as below, eg. Default value of footer text size will be 18 sp,  <dimen name="text_size_footer">18sp</dimen> eg. For tablet -> res/values-sw600dp value of footer textsize will be 25 sp,  <dimen name="text_size_footer">25sp</dimen> Finally read it in a your layout, <TextView     android:id="@+id/lblFooter"
