After setting up my FragmentTabHost with addTab(mTabHost.newTabSpec(....)) I don't know ho to get the reference to the TabSpec.
All I need is to change the name of the tab (tabSpec.setIndicator("new name")) that I initially set with the mTabHost.newTabSpec method.
Thanks!
I find the answer myself. Simply calling this method on the fragmentTabHost object works:
((TextView((RelativeLayout)getTabWidget().getChildAt(tabIndex)).getChildAt(textIndex)).setText("NewTabText");
