I want to use Volley to pull some JSON data from a Service class, but I keep receiving File Cache crashes at RequestQueue mRequestQueue = Volley.newRequestQueue(this); in the service class.
It works fine in my main application.

Look at this post. With the code you have provided us that's all I can think of.
I wasn't passing the correct context.

How do I solve this so that my APP can run properly?
Help me please
Please locate the object in your code
com.megatechnologyteam.megavidi.SplashActivity.onCreate(SplashActivity.java:20)
There should have an object of the class ActionBar attempting calling hide().
This just object is actually null. Please check.
In SplashActivity you are trying to hide the ActionBar which is null (that is why you are getting NullPointerException).
To resolve the issue, remove the line where you are calling ActionBar.hide().
I cannot tell you more than this without seeing the code of SplashActivity.

Also I am Extending AppCompatActivity
So please help me and let me know where I am going wrong
you have not set ActionBar, put this line above
setSupportActionBar(toolbar); // <--- put this
ActionBar.setDisplayHomeAsUpEnabled(true)
Suddently, during regular usage of my Nexus 5, the Google Play Store started crashing every time I try to open it.

I tried to look for this error online, but couldn't find anything. I assume it's related to some system app that has one of her permissions unapproved (I don't know which could be the one), or maybe related to my Xposed Framework installation.
What could it be?
Thank you for your help.
its not any other problem did you see Attempt to invoke virtual method 'void android.app.AppOpsManager.checkPackage(int, java.lang.String)' on a null object reference. you have calling some null object reference.
I am receiving these crash reports from my crash reporting tools.
I don't which code to provide here so just let me know if you want to see any particular code.
I haven't put anything related to GoogleAnalytics in onStart method as it is not mentioned in documentation.
