Equalizer stops 10 seconds after exiting the fragment

Equalizer stops 10 seconds after exiting the fragment - java

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..

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

Splash Screen using AsyncTask

I have a splash screen using AsyncTask, it will download some data from database and store the data in ArrayList. This ArrayList will be used for RecyclerView in fragments of MainActivity.class.
The problem is when I run the app from Android Studio to my phone, everything works perfectly. But, when I destroy the app and run it manually from my phone it will display blank white screen and then it will crash. And if I run once again after it crashed, the app will work. So, this app will always work only if I run it from Android Studio or after it crashed.
The error says that it is caused by the empty list. If I'm not mistaken, I think the AsyncTask doesn't seem to work properly after the activity is destroyed. But I don't know how to fix it. Please help me to solve this problem.

feedList is null. You create feedList instance when DownloadData task is executed. But you call feedList.size() in addBottomDots when fragment view should be created. So, most probably addBottomDots is called before DownloadData task is executed. You need to fix it.

The feedlist in your discover fragment is going empty while initializing. Please set a null check before doing so.It not about running from android studio.If I have understood it correctly you are trying to access a list from splasScreen activity after finishing it. ie in post execute you finish the current activity and the fragment is in main activity,so the list is going null.So if this is the case (and please correct me if not) then either download the data somewhere centrally or best way send it to main activity with intent and use it there. Also when running from android studio kill the app manually and run it again,while the phone is connected and see if it crashes in current scenario.

Detach isn't working (Two Fragments with FlipView)

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.

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!!!

Error with xml HttpGet

I have an app that makes use of an xml obtained with a HttpGet. In the url of the xml request has a key that changes every hour, this key is obtained through another url.
Example: www.test.com/xml?hr=123456
The app tries to get the xml. If errors occur, get the key in another HttpGet and updates in the xml url.
In the emulator works perfectly, but not on the device. Already put a trace and the key is successfully updated. But the xml request error continues.
I tried to put "no cache" in HttpGet
HttpClient client = new DefaultHttpClient (httpParams);
HttpGet get = new HttpGet (url);
get.addHeader ("Cache-Control", "no-cache"); / / HTTP/1.1
get.addHeader ("Expires", "Sat, 26 Jul 1997 05:00:00 GMT");
but it did not work, is there anything that can be done?
