Error:Attempt to invoke virtual method 'android.content.Context android.content.Context.getApplicationContext()'

问题

I'm using fragments in my app but after some time it doesn't respond.I referred some answers for that but i cannot understand them.

viewAllBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (CheckNetworkStatus.isNetworkAvailable(mCtx.getApplicationContext())) {
                    Intent i = new Intent(mCtx.getApplicationContext(),
                            UsersupportlistActivity.class);
                    startActivity(i);
                }
