Note that the OAuth requests to Google API services from embedded browsers are no longer allowed. More info can be found here: https://developers.googleblog.com/2016/08/modernizing-oauth-interactions-in-native-apps.html?m=1

From now on authentication for Google API services will happen via an external browser window.
A new property ExternalBrowser was added to activate this feature. On Windows and Mac platforms this will work automatically. On Android and iOS some extra configuration is required.

Android

• In the Android Libraries section of the Target Platforms list of a project
  • Disable the file “android-support-v4.dex.jar”
  • Add the files “android-support-v13.jar” and “CustomTabs.jar” Both these files are located in the “Android-CustomTabs-Support” subfolder of the installation folder.

iOS

• Add the SafariServices framework to the SDK Manager by right-clicking the iOSDevice 64 target and clicking "Edit SDK". Click in the frameworks section and add a new framework based on the information below:

Use the VoiceFont parameter of the Synthesize call to change the language of the resulting audio. Besides English there are several other languages available, including German, French and Spanish. You can also choose to use a Female or Male voice.

Example:

If a login page from a cloud service is not correctly displayed in the TMSFMXCloudWebBrowser control, you can force your app to use a newer emulated IE version in the Windows registry by adding the executable name at the following location in the registry: HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER \Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION Detailed information can be found here: https://msdn.microsoft.com/en-us/library/ee330730(VS.85).aspx#browser_emulation

The TTMSFMXPayPal control supports the Sandbox environment from the PayPal API that allows processing test payments. Make sure the APIEnvironment property is set to peSandbox and that you are using a Sandbox account. You can find/create Sandbox accounts at the PayPal developers page.
