[help] Reverse app and root - Android Q&A, Help & Troubleshooting

Hi guys,
I need some idea, I have two problems. I'm a beginner...
The first one is the next.
I have reversed an app. I need to see how the app behaves after a purchase (I need to see the network traffic), but after my reverse I can't do any purchase the error is : "The version of the application is not configured for billing..."
Any idea for that ?
The second problem I can't root my emulator, I use android studio.
I've been following this :
https://stackoverflow.com/questions/5095234/how-to-get-root-access-on-android-emulator
But I m stuck at this step :
Make sure you are running adb as root and also you need to remount. Just enter these codes
adb root
adb remount

Click to collapse
I have this message :
Not running as root. Try "adb root" first.
Click to expand...
Click to collapse
Yet this command seems to work :
emulator -avd {emulator_name} -writable-system
Click to expand...
Click to collapse
My OS is windows, and android version is 7.1.
Oh and I have a last question. How I can debug my app when it start ?
adb forward tcp:8700 jdwp:$(timeout 0.5 adb jdwp | tail -n 1)
Click to expand...
Click to collapse
This command not work on windows, I use "adb shell ps" and I take the pid...
Thanks.

A: Make sure your app has android:debuggable="true" in Android Manifest.
B: To debug an application using JDWP:
In Windows:
Open the command prompt
Add to the PATH environment variable <jdk/bin> where jdk is the installation directory of the JDK.
Add the path to Android SDK platform-tools to PATH environment variable.
Reboot computer
Open the command prompt and run
Code:
adb forward tcp:8700 jdwp:<JWPD_ID>
to forward JDWP service to localhost where <JWPD_ID> you obtain via running command
Code:
adb jwpd
In Android Studio:
Turn on "USB debugging" and use "Select debug app" to select your app in "Developer options" on Android device
Start your application
Create a new "Remote" debug configuration (Run->Edit Configurations), and change the debug port to 8700
Select Run -> Debug

Thanks for your answers. I think you did not understand. I can debug my app, but I want to debug when the application start.

To gain ROOT requires you have successfully installed SuperSU app. That's all.
