ContentProviderDatabaseDriver#getTableNames. The method lazily initializes mTableNames, which can lead to race conditions if accessed concurrently by multiple threads. While other methods reading this field may be benign, concurrent execution of getTableNames could result in initialization errors.🔧 Changes Made
Marked
getTableNames(ContentProviderDatabaseDescriptor)as synchronized to ensure thread-safe lazy initialization of mTableNames.
