 # Android Studio
 
 [TOC]
 
 ## Usage
 
 Make sure you have followed [android build instructions](android_build_instructions.md) already.
 
 ```shell
 build/android/gradle/generate_gradle.py
 ```
 
 This creates a project at `out/Debug/gradle`. To create elsewhere:
 
 ```shell
 build/android/gradle/generate_gradle.py --output-directory out/My-Out-Dir --project-dir my-project
 ```
 
 By default, only common targets are generated. To customize the list of targets
 to generate projects for:
 
 ```shell
-build/android/gradle/generate_gradle.py --target //some:target_apk --target //some/other:target_apk
+build/android/gradle/generate_gradle.py --target //chrome/android:chrome_public_apk --target //android_webview/test:android_webview_apk
 ```
 
 For first-time Android Studio users:
 
 * Avoid running the setup wizard.
     * The wizard will force you to download unwanted SDK components to `//third_party/android_tools`.
     * To skip it, select "Cancel" when it comes up.
 
 To import the project:
 
-* Use "Import Project", and select the directory containing the generated project, by default `out-gn/Debug/gradle`.
+* Use "Import Project", and select the directory containing the generated project, by default `out/Debug/gradle`.
 
 You need to re-run `generate_gradle.py` whenever `BUILD.gn` files change.
 
 * After regenerating, Android Studio should prompt you to "Sync". If it doesn't, use:
+    * Button with two arrows on the right side of the top strip.
     * Help -> Find Action -> "Sync Project with Gradle Files"
-
+    * After `gn clean` you may need to restart Android Studio.
 
 ## How it Works
 
 Android Studio integration works by generating `build.gradle` files based on GN
 targets. Each `android_apk` and `android_library` target produces a separate
 Gradle sub-project.
 
 ### Symlinks and .srcjars
 
 Gradle supports source directories but not source files. However, some

 This wrapper can also be used to invoke gradle commands.
 
     cd $GRADLE_PROJECT_DIR && bash gradlew
 
 The resulting artifacts are not terribly useful. They are missing assets,
 resources, native libraries, etc.
 
 * Use a [gradle daemon](https://docs.gradle.org/2.14.1/userguide/gradle_daemon.html) to speed up builds:
     * Add the line `org.gradle.daemon=true` to `~/.gradle/gradle.properties`, creating it if necessary.

 ### What works
 
 * Tested with Android Studio v2.2.
 * Java editing and gradle compile works.
 * Instrumentation tests included as androidTest.
 * Symlinks to existing .so files in jniLibs (doesn't generate them).
+* Editing resource xml files.
 
 ### What doesn't work (yet) ([crbug](https://bugs.chromium.org/p/chromium/issues/detail?id=620034))
 
-* Make gradle aware of resources and assets
+* Make gradle aware of assets
+* Layout editor
 * Add a mode in which gradle is responsible for generating `R.java`
 * Add support for native code editing
 * Make the "Make Project" button work correctly
