We encourage all developers using WebView in their apps to join the\nBeta program so you can try out new WebView versions 4 weeks before they're\nreleased to the public.\n| **Caution:** Beta releases may be less stable than the main release track. Beta users are the first to try out new features, but may also experience more crashes and some apps may not work properly.\n\nHow do I subscribe to the Beta program?\n\nYou can subscribe to WebView Beta on Android 10 and higher by joining the\n[WebView testing program](https://play.google.com/apps/testing/com.google.android.webview) with the account you use on your device. You can do\nthis by clicking the **\"Become a tester\"** button:\n**Figure 1**: Become a tester.\n\nYou're now a Beta tester for WebView! If you visit the Play Store on your\ndevice, you should now see an update available for the Beta track. Install this\nupdate to start using WebView Beta.\n\nHow do I unsubscribe from the Beta program?\n\nTo leave the [WebView testing program](https://play.google.com/apps/testing/com.google.android.webview) and unsubscribe from receiving Beta\nupdates in the future, click the **\"Leave the program\"** button.\n\nAfter you unsubscribe, WebView Beta is still installed on your device, but it\nautomatically updates to the main (Stable) track as soon as the next Stable\nrelease comes out.\n| **Caution:** If you don't want to wait for the next Stable release, you can uninstall WebView updates to immediately get back to Stable. However, we don't recommend doing this, because uninstalling WebView updates may delete user data if apps on your device use WebView to store data.\n\nOther ways to test WebView\n\n- Did you know WebView also has other testing tracks? For a more bleeding edge experience, try out the [Dev or Canary channels](https://chromium.googlesource.com/chromium/src/+/HEAD/android_webview/docs/prerelease.md#trichrome-dev).\n- If you want to try out experimental features or report crashes back to Google, you can install the separate [WebView Beta package](https://play.google.com/store/apps/details?id=com.google.android.webview.beta) instead.\n\nWebview DevTools\n\nWebView DevTools are a set of on-device tools to help debug your WebView apps.\n\nThe best way to launch WebView DevTools is to download WebView Beta, Dev, or\nCanary. These channels contain a launcher icon which launches WebView DevTools.\n**Figure 2**: WebView DevTools.\n\nWebview Crashes\n\nWithin the WebView Beta, Dev, and Canary apps, you can view WebView crashes that\nhave occurred on the device.\n\n- Similar to `chrome://crashes`.\n- Crashes from all apps on the device.\n- File a bug to provide more info.\n\nWebview Flags\n\nSimilarly, the testing apps contain a series of [flags](/guide/webapps/debugging#Testing) you may use to\nenable/disable experimental features.\n\nUsing WebView on older versions of Android\n\nJetpack's [androidx.webkit](/jetpack/androidx/releases/webkit) enables you to use WebView APIs on older versions\nof Android that would otherwise not support them. There are several benefits to\nAndroidX WebKit:\n\n- It is a Jetpack library updated regularly.\n- It is easy to use by design,\n- It enables your WebView apps to work on more devices.\n\nAdd the dependencies for the artifacts you need in the `build.gradle` file for\nyour app or module: \n\nGroovy \n\n```groovy\ndependencies {\n implementation \"androidx.webkit:webkit:1.14.0\"\n}\n```\n\nKotlin \n\n```kotlin\ndependencies {\n implementation(\"androidx.webkit:webkit:1.14.0\")\n}\n```\n\nDeveloper resources\n\nThe following are additional resource for developers.\n\nVideo\n\n- [AndroidX Webkit](https://www.youtube.com/watch?v=7Wq8Lwt_Cbg)\n- [Modern WebView best practices - Android Dev Summit '18](https://www.youtube.com/watch?v=HGZYtDZhOEQ)\n\nDocumentation\n\n- [Web-based content](/guide/webapps)\n- [Espresso Web](/training/testing/espresso/web)\n- [Bug template for reporting issues](https://issues.chromium.org/issues/new?component=1456456&template=1923373)"]]
