Troubleshooting the Plaid Link Android SDK

The Link SDK logs information to LogCat at several points in the flow. Pass a LinkLogLevel value with the LinkTokenConfiguration to see the logs. The levels from least to most verbose: ERROR, WARN, INFO, DEBUG, VERBOSE.

1val linkTokenConfiguration = linkTokenConfiguration {
2  token = "LINK_TOKEN_FROM_SERVER"
3  logLevel = if (BuildConfig.DEBUG) LinkLogLevel.VERBOSE else LinkLogLevel.ERROR
4}

A troubleshooting guide for common OAuth errors is below.

• In Link, after clicking "Continue" on the OAuth screen, nothing happens.

• The user may be using an unsupported browser that is not compatible with Plaid's OAuth redirects, such as DuckDuckGo. For more details on which browsers are supported, see Supported browsers.

• After completing OAuth in the browser or financial institution's app, the user is not redirected back to your app.

• The webpage is unable to locate an app on the device with a package id matching the one used to create the Link token.

• After completing OAuth in the browser or financial institution's app, the Google Play store opened.

• The webpage is unable to locate an app on the device with the package id matching the one used to create the Link token.

After completing OAuth in the browser or financial institution's app, Link opens and then closes again.

• The webpage redirected back to the wrong application on the device causing Link to open and immediately close again as it gets data from a different session.
• You may have both a test and a release version of your app installed on your device and used the wrong package name when creating the Link token.
