This question is asked here many times,I tried all the answers but none of them worked.
I'm getting this error: Error inflating class fragment.

what is causing error?
update:
full project: https://github.com/giusha/Autostop

Perhaps the "Error inflating fragment" message is misleading somewhat - but a closer examination of your error stacktrace shows that it is caused by NullPointerException (because you are calling mProgressBar.setVisibility) whereas mProgressBar is actually NULL - because you assigned it to view.findViewById(R.id.progress_bar); which returns null because the view R.id.progress_bar does not exist in the layout file (fragment_address_fragment). So my suggestion would be to move :
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
into the fragment_address_fragment layout file - and then run your code again and see if it works.

Location only updating TextView when app is out of focus

For some reason it only updates the textviews when the app hits onPause, like when I hit the home button, or multitasking button. Can someone help me figure out why that is?

The reason why you are not getting the location updated in textview is because your code doesn't have a way for the service to communicate back to the activity.
If you want to obtain location only when the activity is in foreground don't use Service and please look into this google's example for obtaining location and updating on a TextView using fused location provider.
I am not sure why you are using a Service.Use Service only when you want to continuously fetch the location even when the app is running background.
For this use any one of the method mentioned here to inform the activity that a new location has been obtained.LocalBroadcast would be your best bet. Anyway explore the best possible solution that suits your usecase in the previous link.

How get location by COARSE location

I'm working on an android app which tracks the distance you ran. I want to be able to use another app ,like a music app, at the same time. I didn't find any good tutorials on how to make the app run in the background, if anybody knows any good tutorials or an easy solution to make the app run in the background I would really apreciate if you would share it with me.

You can use Service for your requirement .
It's an application component that works for a long time in the
background and does not display the user interface. If another
application component starts the service and the user switches to
another application, the service can continue to run in the
background.
You can check sample demo android-service-example and android-service-example2

You could use the wakefulintentservice which runs in different intervals as you set them. There are some examples out there like here:
http://www.programcreek.com/java-api-examples/index.php?api=com.commonsware.cwac.wakeful.WakefulIntentService
This would be recommended, because its not save that your standard service keeps running when the screen is off while jogging.
As for your comment above, you need to bind to the service from your UI and then you are able to call methods on the service. Read the documentation...
