Troubleshooting the Plaid Link Android SDK 
===========================================

#### Enabling Logs 

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`.

```kotlin
val linkTokenConfiguration = linkTokenConfiguration {
  token = "LINK_TOKEN_FROM_SERVER"
  logLevel = if (BuildConfig.DEBUG) LinkLogLevel.VERBOSE else LinkLogLevel.ERROR
}


```

```java
LinkLogLevel logLevel = BuildConfig.DEBUG ? LinkLogLevel.VERBOSE : LinkLogLevel.ERROR;

LinkTokenConfiguration linkTokenConfiguration = new LinkTokenConfiguration.Builder()
    .token("LINK_TOKEN_FROM_SERVER")
    .logLevel(logLevel)
    .build();

```

#### Troubleshooting OAuth errors 

A troubleshooting guide for common OAuth errors is below.

#### No redirect out of app 

##### Link user experience 

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

##### Common causes 

*   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](https://plaid.com/docs/link/web/index.html.md#supported-browsers) .

##### Troubleshooting steps 

#### No redirect back to app 

##### Link user experience 

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

##### Common causes 

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

##### Troubleshooting steps 

#### The Play Store opened upon redirect 

##### Link user experience 

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

##### Common causes 

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

##### Troubleshooting steps 

#### Link opens, then immediately closes upon redirect 

##### Link user experience 

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

##### Common causes 

*   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.
