at the " logger = LogManager.getLogger();" line, is there something else i need
to do so that it recognize my new configFactory ?
{code:title=Log4J2ConfigurationFactory.java|borderStyle=solid}
public class Log4J2ConfigurationFactory extends XmlConfigurationFactory {
private AssetManager assetManager;
public Log4J2ConfigurationFactory(AssetManager assetManager) {
super();
this.assetManager = assetManager;
}
@Override
protected ConfigurationSource getInputFromUri(URI configLocation) {
InputStream inputStream = null;
ConfigurationSource configSource = null;
try {
inputStream = assetManager.open("log4j2.xml");
configSource = new ConfigurationSource(inputStream);
} catch (IOException e) {
//Log.e("tag", e.getMessage());
}
return configSource;
}
}
{code}
> Look for log4j2.xml in assets folder (or the application data) in an Android
> APK.

> Key: LOG4J2-728
> URL: https://issues.apache.org/jira/browse/LOG4J2-728
> Project: Log4j 2
> Issue Type: Bug
> Components: Configurators
> Affects Versions: 2.0-rc2
> Environment: Android
> Reporter: Nelson MELINA
> Labels: android
>
> To add files in an Android apk, you need to put them in an assets folder and
> then they are in an "assets" folder in the APK.
> Log4j 2 needs to find it there when it exists (not the case now).
> Also would it be possible to load the xml configuration file from the
> application data (
> https://developer.android.com/guide/topics/data/data-storage.html ) ?
