Detach isn't working (Two Fragments with FlipView) - java

I'm working with fragments and flipview but I'm having some problems with this.
When my app opens the first screen show my feed with the FlipView. When I choose another tab of my fragments the fragment of the feed didn't hide or detach. I debugged many times and the code arrives in the detached line but didn't work.
Here is my code
MainActivity class
#Override

mTabHost.setup();

#Override
public void onTabChanged(String tabId) {
ft = fm.beginTransaction();
ft.setTransition(FragmentTransaction.TRANSIT_ENTER_MASK);
FeedPrincipalList mFeedFragment = (FeedPrincipalList) fm.findFragmentByTag(TAB_TAG_FEED);
EverythingFragmentList mEverythingFragment = (EverythingFragmentList) fm.findFragmentByTag(TAB_TAG_ALL_EVERYTHING);

Please, help me with this!!!
I'm using the FlipView https://github.com/emilsjolander/android-FlipView
Thanks!!!

Finally I solved this problem.
First I changed my Main Class a little.
I changed this two ifs (this fragments uses FlipView) in the MainActivity class.
if (tabId.equalsIgnoreCase(TAB_TAG_FEED)) {
manageContextualActions(true, false);
if (mFeedFragment == null) {
mFeedFragment = new FeedPrincipalList();
ft.add(R.id.realTabContent, mFeedFragment, TAB_TAG_FEED);
} else {
// mFeedFragment = new FeedPrincipalList();
ft.attach(mFeedFragment);
}
}
if (tabId.equalsIgnoreCase(TAB_TAG_M_PROFILE)) {
manageContextualActions(false, false);
if (mProfileFragmentList == null) {
mProfileFragmentList = new ProfileFragmentList();
ft.add(R.id.realTabContent, mProfileFragmentList, TAB_TAG_M_PROFILE);
} else {
// mProfileFragmentList = new ProfileFragmentList();
ft.attach(mProfileFragmentList);
}
}
Second I changed my method onCreateView of my FeedFragment class.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
context = getActivity().getApplicationContext();
((MainFragmentActivity) getActivity()).setupActionBar(R.string.title_fragment_feed);
fbSessionsManager = new FBSessionsManager(getActivity());
if (mList == null){
view = inflater.inflate(R.layout.feed_flipview, container,true);
mFlipView = (FlipView) view.findViewById(R.id.fv_feedFlipView_FlipView);
mFlipView.setOnFlipListener(this);
mFlipView.setOverFlipMode(OverFlipMode.RUBBER_BAND);
mFlipView.setEmptyView(view.findViewById(R.id.empty_view));
mFlipView.setOnOverFlipListener(this);
new LoadFeedPrincipalData().execute();
}
return super.onCreateView(inflater,container,savedInstanceState);
}
You can see the difference. I only inflate the view in the first time. After this my mList(it's a List of MyGetSetClass) it's not null anymore.
And to finish I Override this two methods on my FeedFragment class.
#Override
public void onDetach() {
super.onDetach();
// Log.i("onDetach", "FeedPrincipalList");
mList = null;
timelinePage = 1;
mPageCount = 0;
}
#Override
public void onStart() {
super.onStart();
// Log.i("onStart", "FeedPrincipalList");
this.mFlipView.setVisibility(View.VISIBLE);
}
#Override
public void onStop() {
super.onStop();
// Log.i("onStop","FeedPrincipalList");
this.mFlipView.setVisibility(View.INVISIBLE);
}
In the detach method I clean all my static variables that I will use when I start the app again.
The onStart and the onStop I use to change the Visibility of my FlipView.
That's it.
I hope this help everyone!!!

Equalizer stops 10 seconds after exiting the fragment

I am a beginner in the world of programming, and now I am working on developing an audio player by adding an equalizer, but I encountered a problem, which is after 10 seconds of pressing the back button and exiting the fragment, the equalizer stops and does not work until after opening the page again.
Also, when playing another audio, the equalizer stops and does not work until the fragment is opened again.
I have tried to fix it but to no avail, Plz Help..

Fragment loading data wrong data when I click in RecyclerView item

So I've been trying to fix this issue for so many hours but can't find the cause behind it.
Issue: My app shows data from my API into recyclerView, a standard feature. The issue comes when I use the search function. When I search for something, my search adapter shows the query data but going back to my Main fragment again, the view loader shows content fine but when I click on it, search items are actually being loaded instead.
Check my app to find out what I'm talking about: https://play.google.com/store/apps/details?id=envision.apps.newsextra
To reproduce, search for something, click on any article from search results, then go back and click any article from main feed, search items are actually being loaded instead.
Here's my main fragment:
public class FeedsFragment extends Fragment implements ArticleListener, LocalMessageCallback {

The error I get is;
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.wowza.gocoder.sdk.sampleapp/com.wowza.gocoder.sdk.sampleapp.PlayerActivity}: java.lang.RuntimeException: Invalid surface: null
You start the stream in onCreate. At this time the Surface used by WOWZPlayerView is not ready yet and the app crashes with the 'Invalid surface' error.
If you look at the sample test in the GoCoder SDK, the playback is started when the user clicks a button. Eg. when the Surface is valid.
Create a button and move your 'mStreamPlayerView.play(mStreamPlayerConfig, statusCallback);' to the button.onClick.
Or ... use any GoCoder SDK v1.7 and more recent.
Please, let me know if I can help any further.
Thanks

Listiview error after update get new data

java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged()
so i'm working with a custom listView when you reach the final of the list i show a footer view and create a listener to implements on the Activity/Fragment that will use the listView. My problem is when i call a services on this method and update the array with the data of the adapter i received that error. I call too a services on the adapter because i need the data of the specific showing row.
Here go my code:
