Android: tabhost in snippet, w / snippets as tabs

as indicated in the header, I am trying to have the tabhost that it contains in the fragment, where the contents of the tab are determined by the fragments. then,

i started with an example of FragmentsTab from Google. this shows how to use snippets as the contents of the tab, but TabHost itself is still hosted in action. again, I need the tab host to be in the fragment.

I took the FragmentsTab example and moved the code to onCreate() and moved it to onCreateView() in my Fragment ,

 @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View fragmentView = inflater.inflate(R.layout.detail_fragment, container); mTabHost = (TabHost) fragmentView.findViewById(android.R.id.tabhost); mTabHost.setup(); mTabManager = new TabManager(getActivity(), mTabHost, R.id.realtabcontent); // TODO: localize mTabManager.addTab(mTabHost.newTabSpec("info").setIndicator("File Info"), InfoFragment.class, null); return fragmentView; }

when I run, I get this exception,

 05-25 14:42:27.272: E/AndroidRuntime(4701): Caused by: java.lang.IllegalStateException: Recursive entry to executePendingTransactions 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1343) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.executePendingTransactions(FragmentManager.java:429) 05-25 14:42:27.272: E/AndroidRuntime(4701): at com.zimbra.octopus.android.TabManager.onTabChanged(TabManager.java:116) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.widget.TabHost.invokeOnTabChangeListener(TabHost.java:359) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.widget.TabHost.setCurrentTab(TabHost.java:344) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.widget.TabHost.addTab(TabHost.java:216) 05-25 14:42:27.272: E/AndroidRuntime(4701): at com.zimbra.octopus.android.TabManager.addTab(TabManager.java:92) 05-25 14:42:27.272: E/AndroidRuntime(4701): at com.zimbra.octopus.android.DetailFragment.onCreateView(DetailFragment.java:46) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:819) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1053) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.BackStackRecord.run(BackStackRecord.java:622) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1371) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.executePendingTransactions(FragmentManager.java:429) 05-25 14:42:27.272: E/AndroidRuntime(4701): at com.zimbra.octopus.android.TabManager.onTabChanged(TabManager.java:116) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.widget.TabHost.invokeOnTabChangeListener(TabHost.java:359) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.widget.TabHost.setCurrentTab(TabHost.java:344) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.widget.TabHost.addTab(TabHost.java:216) 05-25 14:42:27.272: E/AndroidRuntime(4701): at com.zimbra.octopus.android.TabManager.addTab(TabManager.java:92) 05-25 14:42:27.272: E/AndroidRuntime(4701): at com.zimbra.octopus.android.DetailFragment.onCreateView(DetailFragment.java:46) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:819) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1032) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentManagerImpl.addFragment(FragmentManager.java:1111) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.support.v4.app.FragmentActivity.onCreateView(FragmentActivity.java:264) 05-25 14:42:27.272: E/AndroidRuntime(4701): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:563)

looking at the trace, I see onCreateView() for DetailFragment (fragment accepting TabHost ), recursively. one way or another, a call to TabManager.addTab() (again, see the FragmentsTab example) leads to a recursive call to DetailFragment.onCreateView() .

what am I doing wrong? is it even possible? thanks.

Android does not allow you to insert some fragments inside other fragments. Your logarithm indicates that you are executing one fragment transaction in another (i.e., a Recursive record to executePendingTransactions). It's just not allowed, sorry!

add this before setting up TabHost:

 LocalActivityManager mLocalActivityManager = new LocalActivityManager(getActivity(), false); mLocalActivityManager.dispatchCreate(savedInstanceState); mTabHost.setup(mLocalActivityManager);
