Troubleshooting

This section attempts to outline issues that users frequently encounter when first getting accustomed to using react-native-keyboard-controller. These issues may or may not be related to react-native-keyboard-controller.

Incompatible kotlinVersion and failed Android builds​

Sometimes you may see failed Android builds complaining that your version of kotlin is lower than expected version.

error: module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.6.0, expected version is 1.4.1.

To overcome this issue you will need to set higher version of the kotlin:

react-native or expo bare workflow​

You need to modify android/build.gradle and specify correct kotlinVersion:

buildscript {
    ext {
        kotlinVersion = "1.6.21"
    }
}

For more information please, see how it's configured in example project.

Expo managed workflow​

If you are using Expo managed workflow you need to install expo-build-properties

npx expo install expo-build-properties

And add plugin inside of your app.json or app.config.js with following configuration:

{
  "expo": {
    "plugins": [
      [
        "expo-build-properties",
        {
          "android": {
            "kotlinVersion": "1.6.21"
          }
        }
      ]
    ]
  }
}

Swift support​

Since part of this library is written using swift language - your project needs to support it. For that you can create empty .swift file with bridging header. See this step-by-step guide if you have problems.

Animations frame drops​

Sometimes you may see that animation performance is poor. If you are using sentry@5 make sure enableStallTracking is disabled (i. e. enableStallTracking: false) or upgrade to sentry@6,

See this issue for more details.

MutexLockWithTimeout C++ exception​

This exception is thrown when you are trying to use KeyboardProvider or KeyboardAwareScrollView on Android with the new architecture enabled. A top of stacktrace will look like this:
