Hello everyone, I known String message have a NonNull annotation

logger/logger/src/main/java/com/orhanobut/logger/LoggerPrinter.java

Line 182 in 4a85b78

@NonNull private String createMessage(@NonNull String message, @Nullable Object... args) {

but when we use Logger.e(throwable, throwable.getMessage(), TAG); the throwable.getMessage() sometimes is null, and we app crashed. so I add a judgment to message of LoggerPrinter#createMessage().

Exception
