+## Troubleshooting
+
+#### Problem: Duplicate class for kotlin-stdlib:1.8.x
+
+If your project use kotlin 1.7 or lower, you may have this problem, you can choose one of  the following three ways to fix it.
+
+1. Upgrade your kotlin version to 1.8
+
+2. Add bom library to your app module's `build.gradle` file, it will align the kotlin version with 1.8
+   
+   ```kotlin
+   implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.8.10"))
+   ```
+
+3. add `resolutionStrategy` to your app module's  `build.gradle` file to force specifying your kotlin version to build.
+   
+   ```kotlin
+   configurations.all {
+       resolutionStrategy {
+           force("org.jetbrains.kotlin:kotlin-stdlib:1.7.20")
+       }
+   }
+   ```
