What methods should be used for handling requests in cases of unstable internet connection?

In Android applications, the following methods are used to handle requests during unstable internet connections:

• Retry: automatic reattempts of the request at certain intervals with exponential backoff.
• Caching: storing responses locally (e.g., using Room or SharedPreferences) to display data when there is no network.
• Error handling: informing the user about network issues and allowing manual retry.
• Using WorkManager: for deferred execution of tasks that require network connectivity when the connection is restored.

Example using Retrofit and OkHttp for retries:

val okHttpClient = OkHttpClient.Builder()
    .addInterceptor(RetryInterceptor(maxRetries = 3))
    .build()

val retrofit = Retrofit.Builder()
    .client(okHttpClient)
    .baseUrl("https://api.example.com/")
    .build()

Where RetryInterceptor implements the logic for retrying on network errors.

Thus, combining retries, caching, and user notification helps make the app more resilient to internet problems.
