- Method Detail
  - allowRetry
```
boolean allowRetry(int retryCount,
                   long elapsedRetryTime)
```
    Called when retrying an operation failed for some reason. Return true if another attempt is allowed to make.
    
    Parameters:
    
    retryCount - The number of times retried so far (1 for the first time).
    
    elapsedRetryTime - The elapsed time since the operation attempted. (in milliseconds)
    
    Returns:
    
    true if anther attempt is allowed to make. otherwise, false.
  - nextRetryWaitTime
```
long nextRetryWaitTime(int retryCount,
                       long elapsedRetryTime)
```
    Called before making an attempt to retry a failed operation. Return 0 if an attempt needs to be made immediately.
    
    Parameters:
    
    retryCount - The number of times retried so far (0 for the first time).
    
    elapsedRetryTime - The elapsed time since the operation attempted. (in milliseconds)
    
    Returns:
    
    the elapsed time that the attempt needs to wait before retrying. (in milliseconds)
