Hello guys! Can someone explain me why extension function not working with Log class or Crashlytics?

fun Log.dd(msg: String? = "null", tag: String = "test1") = Log.d(tag, msg)

They dont work with statics

[STAYER]

Thanks! They really have private constructor with no chance to create instance.

did you mean msg: String? = null

[Rajkumar Singh]

or msg: String? = "null"

[STAYER]

@Rajkumar Singh, it's just example. I realize 2 extensions, this:

fun Any.logE(msg: String, tr: Throwable? = null, tag: String = "test1") = when (tr) {
    null -> Log.e(tag, msg)
    else -> Log.e(tag, msg, tr)
}

And this:

fun Any.crashlyticsLog(tr: Throwable, msg: String): Unit {
    logE(msg, tr)
    Crashlytics.log(msg)
    Crashlytics.logException(tr)
}

So i can log errors to Logcat and report to crashlytics in one line.
For example:

try {
    //Do something
} catch(e: Exception) {
    crashlyticsLog(e, "some info")
}

@STAYER you need to take a look into Timber library. It's built for that

[STAYER]

@pavi2410 yep, i use Timber in new project, and it is nice)
