kandi X-RAY | retrolambda Summary

retrolambda is a Java library typically used in Telecommunications, Media, Telecom, Server, Runtime Evironment, Maven applications. retrolambda has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub, Maven.

Just as there was Retroweaver et al. for running Java 5 code with generics on Java 1.4, Retrolambda lets you run Java 8 code with lambda expressions, method references and try-with-resources statements on Java 7, 6 or 5. It does this by transforming your Java 8 compiled bytecode so that it can run on an older Java runtime. After the transformation they are just a bunch of normal .class files, without any additional runtime dependencies. [Read more details] #backported-language-features). There is also [limited support] #known-limitations) for backporting default methods and static methods on interfaces. This feature is disabled by default. Retrolambda supports backporting to Java 7, Java 6 and Java 5 runtimes. And for adventurous developers there are [other backporting tools] that may let you go from Java 5 down to Java 1.4. Nowadays Android Studio has [built-in support for Java 8 features] so that is probably the first thing to try out. Otherwise, Retrolambda works also for Android: Serge Zaitsev has written [an article about it] and there is a [Gradle plugin] #gradle-plugin) which makes it easy.

            Firebase crashlytics not able to read crash reports
            Asked 2022-Apr-11 at 14:08

            I have configured crashlytics as per Firebase Documentation https://firebase.google.com/docs/crashlytics/get-started?platform=android. But crash reports not generated and uploaded to server.

            Kindly refer my build details.

            Solved!..
            There was another utility logger library initialized in the application class that prevented crashlytics from collecting log. https://github.com/hypertrack/hyperlog-android

            Also the initialization & manifest part is not necessary unless you want to explicitly enable/disable crashlytics working.

            if you go to the missing library's Github page, you see that it was available only through jcenter, and since jcenter is down, you need to clone the library and build it yourself and put it on the classpath.

            Building CN1 app doesn't work due to problem with retrolambda
            Asked 2021-Jan-16 at 06:31

            My app won't build for iPhone and Android anymore, apparently due to a problem with retrolambda.

            I haven't build for quite some time (I think 6-7 months), but I don't think the way my app uses lambda functions has changed significantly (but I may be wrong, since I am not sure how to read the error message), so I was wondering if something has changed in the CN1 build process?

            If not, any help on how to 'decode' the below error log to understand the problem would be really great. I think I've identified the offending code, but it seems to be written in the same way that compiled successfully before.

            This fails in the retro-lambda stage but has nothing to do with that. See this error:
