# WebView Demo App

**See this page rendered in [Gitiles
markdown](https://android.googlesource.com/platform/frameworks/support/+/androidx-main/webkit/integration-tests/testapp/README.md).**

The WebView/Webkit demo app serves as both a practical demonstration how to use
the latest AndroidX Webkit APIs and as a means to exercise those APIs for manual
testing.

## Reading example code

Examples are organized so that each Activity showcases a small subset of related
APIs. To get started, [find the
Activity](https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:webkit/integration-tests/testapp/src/main/java/com/example/androidx/webkit/)
for the APIs you're interested in learning about.

## Building the demo app

```shell
cd frameworks/support/

# Optional: you can use Android Studio as your editor
./studiow

# Build the app
./gradlew :webkit:integration-tests:testapp:assembleDebug

# Install the app
./gradlew :webkit:integration-tests:testapp:installDebug

# Check for Lint warnings
./gradlew :webkit:integration-tests:testapp:lintDebug

# Run automated espresso tests
./gradlew :webkit:integration-tests:testapp:connectedAndroidTest

# Optional: launch the app via adb
adb shell am start -n com.example.androidx.webkit/.MainActivity
adb shell am start -n com.example.androidx.webkit/.ForceDarkActivity # or, any exported Activity
```

## Extending the demo app

1. Add a new Activity under
   [src/main/java/com/example/androidx/webkit/](src/main/java/com/example/androidx/webkit/).
1. Add this Activity to the end of the `MenuListView.MenuItem[]` array in
   [MainActivity.java](src/main/java/com/example/androidx/webkit/MainActivity.java),
   or in a suitable lower-level Activity, like
   [SafeBrowsingActivity.java](src/main/java/com/example/androidx/webkit/SafeBrowsingActivity.java).
1. Export this Activity in AndroidManifest.xml. Try to organize your Activity
   with other related Activities, or leave space if things are unrelated.
1. If reasonable, write automated test cases for your new Activity, following
   [internal
   documentation](https://docs.google.com/document/d/1dKmNuGiwlJcd-NkIBLK_1RCJCY588usxP0Uw3kOaLWk/edit?usp=sharing).
1. Before uploading a change, please take a [screen
   recording](https://developer.android.com/studio/command-line/adb#screenrecord)
   using the new Activity in the testapp (Googlers should add this to
   http://go/wvsl-demo-app-recordings for posterity).
1. After landing a change, Googlers should upload screenshots and describe
   expected behavior on http://go/wvsl-demo-app-guide for future reference.

## Downloading prebuilt APKs

We **do not** publicly distribute prebuilt APKs. Googlers can download prebuilt
APKs by following [these
instructions](https://docs.google.com/document/d/1K_uOjyTn_UldZP1YxmvCEYXibDn2YB-S_76r3Y-z0bg/edit?usp=sharing).

## Expected behavior (Googlers only)

Most Activities have documentation for the expected behavior. See descriptions
and screenshots at http://go/wvsl-demo-app-guide, and can see screen recording
videos at http://go/wvsl-demo-app-recordings.
