Error with xml HttpGet - java

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?

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..

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

How to solve java.util.concurrent.RejectedExecutionException

The a RejectedExecutionException is thrown when you attempt to submit a task to an executor, and it is refuses it. In this case, there is a clue in the exception message:
java.util.concurrent.ScheduledThreadPoolExecutor#42209b70[
Sh‌​‌​utting down, pool size = 2, active threads = 2,
queued tasks = 0, completed tasks = 248]
This is telling me that you are attempting to submit a task to an Executor that is being shut down.
Now I can't pretend that I understand what your code is actually doing, but I can see that it is using postThread to schedule a Runnable that shuts down the executor. My guess is that the app has done that ... and then it is somehow trying to submit another task.
In reading your code I spotted a couple of places where you catch and then squash Exception. That is a really bad idea. I wouldn't be surprised if that is why you are having trouble debugging your code.

Please help me with the possible solutions i am quite new in Android Development
Your error is coming from OkHttp.
If you search for the error message, you can see where OkHttp is generating it:
https://github.com/square/okhttp/blob/master/okhttp/src/main/java/okhttp3/Request.java#L142
HttpUrl parsed = HttpUrl.parse(url);
if (parsed == null) throw new IllegalArgumentException("unexpected url: " + url);
return url(parsed);
It means that your URL is invalid. As the comment to your question points out: >http://192.168.2.20:8080/jagteraho/batteryStatus/save is not a valid URL.
You need to remove the >.

Status variable returns nullPointerException (Android)

I have been following a tutorial (http://www.androidhive.info/2012/08/android-working-with-google-places-and-maps-tutorial/) in order to make a listview display nearest restaurant to your location in radius of 5km.
However i keep getting an error, in my Runnable it says that the status variable is null. I don't really understand why this error pops up. Can you guys give me a short explanation and help find a solution??

Line 132 of DisplayLocations.java is :
String status = nearPlaces.status;
This is the stacktrace :
java.lang.NullPointerException: Attempt to read from field 'java.lang.String com.example.dell.exampleapplication.PlacesList.status' on a null object reference

Any help and explanation would be appreciated.
Thanks, have a nice day.
EDIT:
nearPlaces.status = ... (the status: probably from GooglePlaces) in doInBackGround
then you can do:
String status = nearPlaces.status; in onPostExecute
Add the line
#Override
protected String doInBackground(String... params) {
googlePlaces = new GooglePlaces();
try{
String types = "cafe|restaurant";
double radius = 5000;
nearPlaces = googlePlaces.search(gps.getLatitude(), gps.getLongitude(), radius, types);
nearPlaces.status = "OK"; //Add this line for testing, your code should work now, because status is not NULL anymore.
}catch (Exception e){
e.printStackTrace();
}
return null;
}
