I don't know if this is good answer for you. I had similar problems with

|How to install a apk on emulator in Android Studio?|
You can install .apk files to emulator regardless of what you are using
(Eclipse or Android Studio)
here's what I always do: (For full beginners)
1- Run the emulator, and wait until it's completely started.
2- Go to your sdk installation folder then go to platform-tools (you should
see an executable called adb.exe)
3- create a new file and call it run.bat, edit the file with notepad and
write CMD in it and save it.
4- copy your desired apk to the same folder
5- now open run.bat and write adb install "your_apk_file.apk"
6- wait until the installation is complete
7- voila your apk is installed to your emulator.
Note: to re-install the application if it already existe use adb install -r
sorry for the detailed instruction as I said for full beginners

Assuming that there are no errors when you are writing your code in

|Why is it possible to use Android Support v4 on an Android 4.0.3 emulator|
Android v4 Support Library supports all Android OS above 4 (Android 1.6),
the same goes for the v7 (Android 2.1) and v11 (Android 3.0) version of the
support library. The functions these support libraries use are not tied to
Google services, so you do not need to target images with Google services
built in (i.e. "Google APIs - API Level 15").
If your app uses Google Play services, however, you would need to target
"Google APIs - API Level 15".

|how to enable trace in android 4.3 as in android 4.2|
From the Official Doc.
Systrace events for apps
Android 4.3 adds the Trace class with two static methods,
beginSection() and endSection(), which allow you to define blocks of
code to include with the systrace report. By creating sections of
traceable code in your app, the systrace logs provide you a much more
detailed analysis of where slowdown occurs within your app.
For information about using the Systrace tool, read Analyzing Display

|Automatically versioning Android project from git describe with Android Studio/Gradle|
After some further reading and several false starts, I ended up with this,
added to the bottom of build.gradle in the project directory (that is,
MyAppProject/MyApp/build.gradle, not MyAppProject/build.gradle --
confusing, I know, but the former directory is projectDir in Gradle so
that's how I refer to it here). It depends on no external utilities other
than Git, which is assumed to be in the path, so it should work on any OS
(even though I used forward slashes in the paths, they get converted to
backslashes on Windows).
It could probably stand to be improved, I'm sure, as my understanding of

|Is it possible to test In App Billing in an Android App connected to and running from Android Studio|
Except for the static purchase test items, you are generally no longer able

Console to do so.
So to answer your main question, while you can track the overall flow of
your purchase feature in debug mode on your app, you won't be able to test
a successful transaction while using the debugger.
