问题 I'm having some problems with Android Studio at the moment because I recently started using "Vector Assets". I've done absolutely everything necessary to display them correctly in my application (using the app:srcCompat="" in the xml, android {defaultConfig {vectorDrawables.useSupportLibrary true}} in the build.gradle, and AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); in the onCreate() method before setContentView() ).

Or do I have to set the DefaultUncaughtExceptionHandler? I read JavaDocs: Uncaught exception handling is controlled first by the thread, then by the thread's

Then I added some codes from http://shivasoft.in/blog/java/snmp/create-snmp-client-in-java-using-snmp4j/ and http://shivasoft.in/blog/java/snmp/creating-snmp-agent-server-in-java-using-snmp4j/ to check my agent. But now These strings printed in console: Exception in thread "main" java.lang.RuntimeException: java.net.BindException: Address already in use: Cannot bind at org.snmp4j.transport.TransportMappings
