Milliseid meetodeid saab kasutada programmi vigade haldamiseks ja töötlemiseks?

In Android, the following methods are used for error management and handling:

1. Exception handling (try-catch) — the standard way to catch and handle exceptions that occur during execution.

2. Using onError in RxJava or other reactive libraries — for asynchronous error handling.

3. Error handling in callbacks and listeners — for example, in network requests via Retrofit, error handling can be implemented in callback methods.

4. Using CoroutineExceptionHandler in Kotlin Coroutines — to catch exceptions in coroutines.

5. Logging errors — via Log.e() or external libraries (Crashlytics, Timber) for later analysis.

6. Custom error handlers — for example, a global exception handler via Thread.setDefaultUncaughtExceptionHandler.

Example of exception handling:

try {
    // code that may throw an exception
} catch (IOException e) {
    // input/output error handling
    Log.e("TAG", "Error reading file", e);
}
