Preview page flowchart
To help you debug your Dynamic Links, you can preview your Dynamic Links' behavior on
different platforms and configurations with an automatically-generated
flowchart. Generate the flowchart by adding the
d=1 parameter to
any short or long Dynamic Link. For example,
app_code.app.goo.gl/path?d=1 for a
short Dynamic Link.
The preview page looks like this:
iOS self-diagnostic tool
If you are having issues with your Dynamic Link integration on iOS, use the self-diagnostic tool which is built into the Dynamic Links SDK versions 2.1.0 and newer.
The tool can be invoked from anywhere in your code as follows.
By default, the tool prints debug information, including any detected errors, to standard output. For example, let's say your iOS app isn't receiving Dynamic Links as expected. The self-diagnostic tool will output information like:
---- Firebase Dynamic Links diagnostic output start ---- Firebase Dynamic Links framework version 2.1.0 System information: OS iOS, OS version 11.0, model iPhone Current date 2017-08-14 22:52:56 +0000 AutomaticRetrievalEnabled: YES ERROR: Specified custom URL scheme is com.google.AppInvitesSample.dev but Info.plist do not contain such scheme in CFBundleURLTypes key. AppID Prefix: EQHXZ8M8AV, Team ID: EQHXZ8M8AV, AppId Prefix equal to Team ID: YES performDiagnostic detected 1 ERRORS. ---- Firebase Dynamic Links diagnostic output end ----
In this example, Dynamic Links isn't working because the custom URL scheme isn't properly configured.
