If your Android app utilizes
WebView
to display web content, it's
recommended to configure it so that content can be optimally monetized with ads.
This guide shows you how to provide information about how to configure a
WebView
object.
Enable third-party cookies
To improve your user's ad experience and be consistent with Chrome's
cookie policy, enable third-party
cookies on your WebView
instance.
Java
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
Kotlin
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true)

預設的「WebView
」設定不會針對廣告進行最佳化。使用
WebSettings
敬上
用來設定 WebView
的 API:
- JavaScript
- 存取本機儲存空間
自動播放影片
Java
import android.webkit.CookieManager;
import android.webkit.WebView;
public class MainActivity extends AppCompatActivity {
private WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webview);
// Let the web view accept third-party cookies.
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
// Let the web view use JavaScript.
webView.getSettings().setJavaScriptEnabled(true);
// Let the web view access local storage.
webView.getSettings().setDomStorageEnabled(true);
// Let HTML videos play automatically.
webView.getSettings().setMediaPlaybackRequiresUserGesture(false);
}
}
Kotlin
import android.webkit.CookieManager
import android.webkit.WebView
class MainActivity : AppCompatActivity() {
lateinit var webView: WebView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
webView = findViewById(R.id.webview)
// Let the web view accept third-party cookies.
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true)
// Let the web view use JavaScript.
webView.settings.javaScriptEnabled = true
// Let the web view access local storage.
webView.settings.domStorageEnabled = true
// Let HTML videos play automatically.
webView.settings.mediaPlaybackRequiresUserGesture = false
}
}
Load web view content
Cookies and page URLs are important for web view monetization and only function
as expected when is used with a
network-based URL. For optimized WebView
performance,
load web content directly from network-based URLs. Avoid using
WebViewAssetLoader
, loading
assets from the device, or generating web content dynamically.
Java
import android.webkit.CookieManager;
import android.webkit.WebView;
public class MainActivity extends AppCompatActivity {
private WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webview);
// Let the web view accept third-party cookies.
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
// Let the web view use JavaScript.
webView.getSettings().setJavaScriptEnabled(true);
// Let the web view access local storage.
webView.getSettings().setDomStorageEnabled(true);
// Let HTML videos play automatically.
webView.getSettings().setMediaPlaybackRequiresUserGesture(false);
// Load the URL for optimized web view performance.
webView.loadUrl("https://webview-api-for-ads-test.glitch.me");
}
}
Kotlin
import android.webkit.CookieManager
import android.webkit.WebView
class MainActivity : AppCompatActivity() {
lateinit var webView: WebView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
webView = findViewById(R.id.webview)
// Let the web view accept third-party cookies.
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true)
// Let the web view use JavaScript.
webView.settings.javaScriptEnabled = true
// Let the web view access local storage.
webView.settings.domStorageEnabled = true
// Let HTML videos play automatically.
webView.settings.mediaPlaybackRequiresUserGesture = false
// Load the URL for optimized web view performance.
webView.loadUrl("https://webview-api-for-ads-test.glitch.me")
}
}
Test the web view
During app development, we recommend that you load this test URL:
https://webview-api-for-ads-test.glitch.me#webview-settings-tests
to verify these settings have the intended effect on ads. The test URL has success criteria for a complete integration if the following are observed:
Web view settings
- Third-party cookies work
- First-party cookies work
- JavaScript enabled
- DOM storage enabled
Video ad
- The video ad plays inline and does not open in the full screen built-in player
- The video ad plays automatically without clicking the play button
- The video ad is replayable
After testing is complete, substitute the test URL with the URL the web view intends to load.
