Failed to instantiate type ch.qos.logback.ext.loggly.LogglyAppender in Android

[keyuraashra]

I am working on Android native app and I have successfully integrated logback with LOGCAT and now trying to integrate it with loggly but I am getting some issue with it and I thought this is the best place to get guidance/resolution of it.

build.gradle :-

compile 'org.logback-extensions:logback-ext-loggly:0.1.2'

logback.xml :-

<configuration>

    <appender name="LOGCAT" class="ch.qos.logback.classic.android.LogcatAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="LOGGLY" class="ch.qos.logback.ext.loggly.LogglyAppender">
        <endpointUrl>
            https://logs-01.loggly.com/inputs/d6415bd0-88f4-407d-8e89-bd9c4c95ef6f/tag/logback
        </endpointUrl>
        <encoder>
            <pattern>%d{"ISO8601", UTC} %p %t %c{0}.%M - %m%n</pattern>
        </encoder>
    </appender>

    <logger name="co.pointwise.android.sdk" level="debug" additivity="false">
        <appender-ref ref="LOGGLY" />
    </logger>

    <root level="debug">
        <appender-ref ref="LOGCAT" />
    </root>
</configuration>

Any idea what is going wrong here?

[tony19]

For starters, it looks like logback-extensions isn't in your classpath based on:

Caused by: java.lang.ClassNotFoundException: Didn't find class "ch.qos.logback.ext.loggly.LogglyAppender" on path: DexPathList[[zip file "/data/app/co.librarytest-2/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]

Can you add the library to your classpath and retest?

[keyuraashra]

I am testing with Jar now, just want to add one more thing which might help. I am working on library project and I am including AAR file in main project and I have integrated logback in library project. Is there anything which cause the issue in this case as i can see its printing on base.apk with Dex?

proguard:-
-keep class ch.qos.** { ; }
-keep class org.slf4j.* { ; }
-keepattributes *Annotation

[manvinderKalsi]

Did this ever worked. I am having a hard time getting this configured in my application.
Have to do it through in code statements and then getting error: android.os.NetworkOnMainThreadException

Is there anything i am missing?

[grote]

Adding this to my proguard file gets rid of the error:

-keep class ch.qos.logback.classic.android.LogcatAppender

[vijaycaimi]

worked for me by adding new version of logback
