eclipse - Android Crash - how to debug this? -


i'm getting intermittent crashes in android app running on physical device. app has several screens buttons , listview. has 2 threads - main ui thread , worker thread receives information on wifi. worker thread never directly touches ui components. when gets information on wifi uses runonuithread call routine writes arraylist read ui.

in past when got crash in stack trace in debug tab of debug perspective , find of own code , clue bug was, stack dump has nothing of mine - it's internal. furthermore, says "runtime exception", not exception . . .

thread [<1> main] (suspended (exception runtimeexception))
activitythread.performstopactivityinner(activitythread$activityclientrecord, activitythread$stopinfo, boolean) line: 2434
activitythread.handlestopactivity(ibinder, boolean, int) line: 2479 activitythread.access$1800(activitythread, ibinder, boolean, int) line: 117 binderproxy(activitythread$h).handlemessage(message) line: 952 activitythread$h(handler).dispatchmessage(message) line: 99 looper.loop() line: 130 activitythread.main(string[]) line: 3687
method.invokenative(object, object[], class, class[], class, int, boolean) line: not available [native method] method.invoke(object, object...) line: 507 zygoteinit$methodandargscaller.run() line: 842
zygoteinit.main(string[]) line: 600 nativestart.main(string[]) line: not available [native method]

thread [<8> binder thread #2] (running)

thread [<7> binder thread #1] (running)

thread [<9>> thread-10] (running)

thread [<10> binder thread #3] (running)

another factor: crash happens sporadically, , there's no specific sequence reproduce - has doing - pressing button or receiving data - won't crash sitting on table doing nothing - it's not same thing reproduce it.

how figure out i'm going wrong?

this line gives me hunch:

method.invokenative(object, object[], class, class[], class, int, boolean) line: not available

the fact it's coming out of native api suggests may api version problem. check problems view (if you're using eclipse) , grep code @suppresslint annotations , make sure you're not ignoring or suppressing "new api" or "inlined api" compiler warnings.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
