Need to update instructions for running hello_services app in Android Studio

[raju-bitter]

Steps to Reproduce

With the instructions provided here https://github.com/flutter/flutter/tree/master/examples/hello_services, I was not able to run the hello_services app on an Android device. Instead here is what I had to do:

1) Checkout Flutter source
git clone https://github.com/flutter/flutter

2) In examples/hello_services/android, create local.properties file
Content for my setup:
sdk.dir=/Users/raju/Library/Android/sdk
flutter.sdk=/Users/raju/dev/flutter
flutter.buildMode=debug

3) Open project folder examples/hello_services/android with Android Studio
Tested with Android Studio 2.2.2. The IDE will show a message like:
"Gradle settings for this project not configured yet.
Would you like the project to use the Gradle wrapper?"

Clicked OK, Android Studio will index and build the project. Shows error message:

Error:Cause: failed to find target with hash string 'android-22' in: /Users/raju/Library/Android/sdk
Install missing platform(s) and sync project

I have Android SDK 6.0 installed, with SDK Build tools 24.0.0.

4) Set the SDK target version
In file examples/hello_services/android/app/build.gradle, I set the following
version numbers:

android {
compileSdkVersion 23
buildToolsVersion '24.0.3'

5) Rebuild project
Output:

• What went wrong:
  Execution failed for task ':app:compileDebugJavaWithJavac'.

  Compilation failed; see the compiler error output for details.

• Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

6) Fix compile error by commenting out line #20 in ExampleActivity.java
To fix this compile error, I commented out this line and rebuild the project.
hello_services/android/app/src/main/java/com/example/flutter/ExampleActivity.java:20

Build output:

followed the instructions...but got this..

$ adb shell pm uninstall com.example.flutter

Error while Installing APK

[jason-simmons]

For the INSTALL_FAILED_NO_MATCHING_ABIS error: currently the Gradle example only supports ARM targets and will not build APKs that run on an x86 emulator

[eseidelGoogle]

We have a team working on improving hello_services right now. FYI @mit-mit

[mit-mit]

This should now be working with no steps required. You should be able to open all the samples, as well as new projects created with flutter create, in Android Studio.

There is only a single know issue: Note that you need to build the Flutter app at least once before opening in Android Studio (see #8365)

[mit-mit]

Also, the current hello_services sample will be split into two samples that are both being updated. Please keep an eye on #7810.

I will close this bug for now.
