+- Terms and Conditions

+### Important WebView Error Note
+
+Some websites may fail to load small internal resources such as favicon, analytics scripts, CSS, images, or iframe content. KAlertDialog only reports the error callback for the main page load, so your app does not show false error messages when the main WebView page loads successfully.

+### WebView page is not loading
+
+If your WebView dialog does not load an online URL, make sure your app has Internet permission:
+
+```xml
+<uses-permission android:name="android.permission.INTERNET" />
+```
+
+Also make sure the URL starts with `https://`:
+
+```java
+.setWebViewUrl("https://example.com/privacy-policy")
+```
+
+---
+
+### WebView shows error even when page loads
+
+Some websites may fail to load small sub-resources such as favicon, analytics scripts, images, CSS files, or iframe content. These are not always main page errors.
+
+KAlertDialog handles this by reporting WebView errors only when the main page fails to load.
+
+If you use `setWebViewPageListener()`, show user-facing errors only inside `onPageError()`.
+
+---
+
+### WebView content is too small on tablets
+
+For tablets, use a larger WebView height:
+
+```java
+.setWebViewHeight(460)
+```
+
+If you are using a `layout-sw600dp` dialog layout, make sure the dialog width is larger, for example:
+
+```xml
+android:layout_width="560dp"
+```
