I have a problem, I made an application that consumes a webservice RestFull made in Visual Studio, when I run the Android Studio application, it consumes without problems, but when I use it on the device (Galaxy S4) or Samsung Tablet, it does not work and always gives error on the same line.
br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
I tried to use logcat to see the java.io.FileNotFoundException: http://192.168.25.115/wsBA.asmx/ConsultarLogin error in the exception.
The worst thing is that in the emulator it works, I accessed the webservice from another computer that I have to see if it was a matter of access permission, however passing the parameters via GET direct in browser of the other micro access.
Below is the Actvity code that is giving this error:

Issue
1) About the permissions this is in androidmanifest.xml

<uses-permission android:name="android.permission.USE_CREDENTIALS" /> <!-- To retrieve the account name (email) as part of sign-in: -->

2) You are connected to the same wireless network that is here in my room.
3) I already had disabled firewall and antivirus, on the webservice I access from my notebook normally.
O I noticed something else the example I got to do mine works without problem. I already have my error in the device only in the line:
br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
I noticed one more thing: that my application does and the example does not, when it runs the message appears several times in logcat:
Skipped 300 frames! The application may be doing a lot of work on its main thread.
This number 300 varies.
