performance - High Javascript CPU use for webapp -


i've reached point i'm fishing , hoping catch something.

the chrome performance tool shows whole cpu (so far tool detects, @ least) taken timeupdate events, nothing else firing. event isn't referenced anywhere in code or in dependencies (via github search).

i reached point ran $("body").empty().off() , $(window).off() remove events , elements doing anything, , inserted debugging code loop through functions , redefine them undefined.

i ran logging on setinterval , settimeout clear of those.

i worked through chrome inspector's "event listener" tab , manually removed events.

i run cleanup helper nukes else think of:

window.cleanupelements = ->   $("*").off()   $("style").remove()   $("link").remove()   $("script").remove()   false

this white page no body content, functions, timers, intervals, or events still sitting pretty @ 50%+ cpu use.

ideas?

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
