Great work guys with the library, but currently there is a small problem:
Paging version: 3.3.0-alpha02-0.5.1
Platform: JVM
The built-in logging cannot be configured.
This leads to thousands of lines of VERBOSE and DEBUG output.
Currently the JVM PagingLogger is hardwired for some reason: isLoggable() always returns true.
PagingLogger.jvm.kt:
package androidx.paging
import androidx.annotation.RestrictTo
@RestrictTo(RestrictTo.Scope.LIBRARY_GROUP)
public actual object PagingLogger {
public actual fun isLoggable(level: Int): Boolean {
return true
}
// consider using java.util.logging APIs instead
public actual fun log(level: Int, message: String, tr: Throwable?) {
print("\n$message")
}
}example log spam when scrolling a paginated list:
