You can also download "slf4j I had the same on Android. This is how i fixed it: including ONLY the file: slf4j-api Obviously, the rest of the libs can be there android-support-v4, etc Versions: Eclipse Kepler 06 14 - 02 29 ADT Sign up or log in Sign up using Google.

Since 1. This is deemed to be better than leaving the user wondering about the reasons of the StackOverflowError. If SLF4J is bound with slf4j-jcl. This error indicates that appropriate SLF4J binding could not be found on the class path.
This error is reported when org. MDC class has not been initialized correctly. Same cause and remedy as the previously listed item. Note that the replayed logging calls are subject to filtering by the underlying logging system. In principle, replaying only occurs for apllications which are already multi-threaded at the time the first logging call occurs.
Highly configurable logging systems such as logback and log4j may create components which invoke loggers during their own initialization. However, since the binding process with SLF4J has not yet completed because the underlying logging system was not yet completely loaded into memory , it is not possible to honor such logger creation requests. To avoid this chicken-and-egg problem, SLF4J creates substitute loggers during this phase initialization.
Calls made to the substitute loggers during this phase are simply dropped. After the initialization completes, the substitute logger will delegate logging calls to the appropriate logger implementation and otherwise will function as any other logger returned by LoggerFactory. If any substitute logger had to be created, SLF4J will emit a a listing of such loggers.
This list is intended to let you know that any logging calls made to these loggers during initialization have been dropped. The trace level was added to log4j in version 1. Thus, starting with SLF4J 1. However, as reported in issue 59 , in some environments it may be difficult to upgrade the log4j version.
With an earlier slf4j-api. Placing slf4j-api. Note that this problem only occurs with logback version 1. Class path contains SLF4J bindings targeting slf4j-api versions prior to 1.
IllegalStateException: org. LoggerFactory in failed state. The method o. Under the hood the Java compiler transforms the varargs part in methods into Object[]. Thus, the Logger interface generated by the compiler is indistinguishable in 1. It follows that SLF4J version 1. Given the extent of the improvement, users are highly encouraged to migrate to SLF4J 1. By backward-compatible, we mean that existing logging frameworks do not have to be changed in order for the user to benefit from the fluent logging API.
See the relevant FAQ entry for more details. As customary in programming tradition, here is an example illustrating the simplest way to output "Hello world" using SLF4J. It begins by getting a logger with the name "HelloWorld". This logger is in turn used to log the message "Hello World". To run this example, you first need to download the slf4j distribution , and then to unpack it. Compiling and running HelloWorld will result in the following output being printed on the console.
The warning will disappear as soon as you add a binding to your class path. Compiling and running HelloWorld will now result in the following output on the console. The sample code below illustrates the typical usage pattern for SLF4J.
See the question "What is the fastest way of logging? The idea is to build a logging event piece by piece with a LoggingEventBuilder and to log once the event is fully built. Logger interface, return an instance of LoggingEventBuilder. For disabled log levels, the returned LoggingEventBuilder instance does nothing, thus preserving the nano-second level performance of the traditional logging interface.
The following log statements are equivalent in their output for the default implementation :. The fluent logging API allows the specification of many different types of data to a org.
Logger without a combinatorial explosion in the number of methods in the Logger interface. It is now possible to pass multiple Markers , pass arguments with a Supplier or pass multiple key-value pairs. Key-value pairs are particularly useful in conjuction with log data analysers which can interpret them automatically.
The key-value pair variant of the API stores the key-value pairs as separates objects. Webm converter. Flv converter. Mkv converter. Avi converter. Mov converter. Wmv converter.
