android - How do you control Eclipse's generated Bluetooth java files? -

i've got android project built under eclipse-indigo works fine. copied many of files , rebuilt under eclipse-juno. app runs if install and/or run eclipse, if try generate apk, get: conversion dalvik format failed: unable execute dex: multiple dex file define landroid/bluetooth/ibluetooth; comparing directories shows src/android.bluetooth/ibluetooth.aidl , ibluetoothcallback.aidl identical, gen/android.bluetooth exists in working version not broken one. replacing these files manually makes eclipse whine, of course, question is: how control how eclipse generates particular files aidl inputs? alternatively, if has intelligent suggestion how rid of stupid error, i'll take instead :-) the answer not install android development kit, seems have borked libraries. instead, install eclipse java developers, , install android sdk separately. allowed correct libraries appear, , didn't give stupid errors duplicate dex files.

ruby - How to do blocking subscribe using bunny RabbitMQ client? -

in java rabbitmq client can (code in ruby): consumer = queueingconsumer.new(channel); channel.basicconsume(queue_name, true, consumer); consumer.nextdelivery.getbody and third line blocks thread until message comes. how achieve in bunny client? can use block: channel.queue('').bind(@x, :routing_key => rk).subscribe(block: true) |_, _, payload| # end or non blocking pop: delivery_info, properties, payload = q.pop is there way achieve in jruby client using bunny? reason want after receiving message continue job in current context. the call subscribe blocking due passing :block => true . if need access payload outside of block, can take advantage of ruby's scoping rules: the_payload = nil queue = channel.queue('').bind(@x, :routing_key => rk) queue.subscribe(block: true) |delivery_info, _, payload| the_payload = payload channel.consumers[delivery_info.consumer_tag].cancel end # the_payload 1 received in block!
