NewRelic.recordHandledException( exception: Exception?, exceptionAttributes: Map<String?, Any?>?)NewRelic.recordHandledException(throwable: Throwable?)NewRelic. recordHandledException( throwable: Throwable?, attributes: Map<String?, Any?>?)Description
Records a handled exception or other throwable type. Optionally takes map with additional attributes showing context.
Use recordHandledException() within a try{...} catch(){...} block to help understand how often your application is throwing exceptions, and under what conditions.
In addition to associated custom attributes, the events will also have associated session attributes. You can view event data in the mobile monitoring UI in the Crash event trail, or via NRQL.
Parameters
Parameter | Type | Description |
|---|---|---|
|
| Required. The exception to be recorded. |
|
| Optional. A map of attributes to be associated with the exception. |
Return values
Returns true if recorded successfully, or false if not.
Examples
Here's an example of recording a ClassCastException from within an on-click listener:
Java
public class MainActivity extends Activity { ... coolButton.setOnClickListener(new View.OnClickListener() { Map myMap = new HashMap<>(); @Override public void onClick(View view) { try { myMap.put("Key", "Value"); Integer stringVar = (Integer) myMap.get("Key"); // throws ClassCastException } catch (Exception e) { NewRelic.recordHandledException(e, myMap); } } }); ...}Kotlin
class MainActivity : AppCompatActivity() { ... binding.fab.setOnClickListener { view -> val myMap = mutableMapOf<String,Any>() try { myMap["Key"] = "Value" Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) .setAnchorView(R.id.fab) .setAction("Action", null).show() }catch (exception:Exception) { NewRelic.recordHandledException(exception,myMap) } } ...}Syntax
Objective-c
recordHandledException:(NSException* __nonnull)exception withAttributes:(NSDictionary* __nullable)attributes;Description
Records a handled exception (Objective-c only). Optionally takes a map with additional attributes showing context.
The recordHandledException API is useful for crash analysis; the captured events will help you understand how often your application is throwing exceptions and under what conditions. In addition to associated custom attributes, the events will also have associated session attributes.
This API takes an instance of an NSException and an optional NSDictionary attribute dictionary, then creates a recordHandledException event. You can view event data in the Crash event trail UI, and query them with NRQL.
Important
This function should not be used with Swift code. Please use recordError to track handled errors in Swift code.
Parameters
Parameter | Type | Description |
|---|---|---|
|
| Required. The exception to be recorded. |
|
| Optional. Dictionary of attributes that give context. |
Return values
Returns true if the event is recorded successfully, or false if not.
Examples
Here's an example of a simple handled exception:
try { @throw [NSException exceptionWithName:@"versionException" reason:@"App version no longer supported" userInfo:nil];} @catch (NSException* e) { [NewRelic recordHandledException:e];}Here's another example or a handled exception with a dictionary:
NSException* exception = [NSException exceptionWithName:@"MyException" reason:@"I have my reason" userInfo:nil];
NSDictionary* dictionary = @{@"int" : @1, @"Test Group" : @"A | B"};
