I have Webview in my app.Recently i tried to login in gmail but got Error "Error 403:disallowed_useragent".
From Documentation I used
Mozilla/5.0 (Linux; Android 4.4; Nexus 4 Build/KRT16H) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/30.0.0.0 Mobile Safari/537.36 But my app crash
E/chromium: [ERROR:validation_errors.cc(76)] Invalid message: VALIDATION_ERROR_DESERIALIZATION_FAILED (safe_browsing.mojom.SafeBrowsing.0 ) E/chromium: [ERROR:render_process_host_impl.cc(4990)] Terminating render process for bad Mojo message: Received bad user message: Validation failed for safe_browsing.mojom.SafeBrowsing.0 [VALIDATION_ERROR_DESERIALIZATION_FAILED (safe_browsing.mojom.SafeBrowsing.0 )] [ERROR:bad_message.cc(27)] Terminating renderer for bad IPC message, reason 123 E/chromium: [ERROR:validation_errors.cc(76)] Invalid message: VALIDATION_ERROR_DESERIALIZATION_FAILED (network.mojom.URLLoaderFactory.0 ) E/chromium: [ERROR:render_process_host_impl.cc(4990)] Terminating render process for bad Mojo message: Received bad user message: Validation failed for network.mojom.URLLoaderFactory.0 [VALIDATION_ERROR_DESERIALIZATION_FAILED (network.mojom.URLLoaderFactory.0 )] [ERROR:bad_message.cc(27)] Terminating renderer for bad IPC message, reason 123 E/chromium: [ERROR:aw_browser_terminator.cc(125)] Renderer process (14677) crash detected (code -1). E/chromium: [ERROR:aw_browser_terminator.cc(90)] Render process (14677) kill (OOM or update) wasn't handed by all associated webviews, killing application. So I like to know How to construct a user agent string which i can use for every site.I will be more thank full if someone tells me the importance of user agent.
