android - how to set heap size to minimum when application was closed -

i developing 1 android application using more images resolution 640*960 approximately. these images loaded bitmaps proper scaling factor.

when loading bitmpas heap size increasing , not decreasing though recycling bitmpas. read few theory's regarding issue maximum says 1 time heap increased not decreased @ all.

my problem if close application when heap size 10mb , , when reopen application heap starts 10mb. causes vm exceeds maximum heap memory , out of memory after time.

what have this, , guarantee application never close out recycling bitmaps.

can 1 please suggest me how minimze heap memory , solve oom.

even faced same problem....you can refer link loading bitmaps http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

once heap size has exceeded limit garbage collector runs...and cleans unwanted object.so improve not phone call garbage collector run automatically.

applications running on api level 11+ can have android:largeheap="true" on element in manifest request larger-than-normal heap size

in oncreate method in activity can utilize this(i did'nt seek this) dalvik.system.vmruntime.getruntime().setminimumheapsize(yournumberhere);

ruby - How to find out why rails server hangs at 100%? -

can think of way find out our rails production server hangs? cpu @ 99% assume gets lost in while/for/each loop. unfortunately can't find candidate loop.

the problem not occur in development , our test suit has 100% code coverage.

we attaching ruby via gdb, didn't know go there. ideas?

once have attached gdb busy looping process phone call rb_backtrace gdb:

> phone call rb_backtrace()

the output rb_backtrace similar crash report, , output go log files similar standard ruby error backtrace.

from there should step closer solution since see in ruby code process stuck.

java - Suppressing GPG signing for Maven-based continous integration builds (Travis CI) -

java - Suppressing GPG signing for Maven-based continous integration builds (Travis CI) -

i'm using travis-ci provide continuous integration builds few java open source projects i'm working on.

normally works smoothly, have problem when pom specifies gpg signing, e.g.

<plugin> <groupid>org.apache.maven.plugins</groupid> <artifactid>maven-gpg-plugin</artifactid> <version>1.4</version> <executions> <execution> <id>sign-artifacts</id> <phase>verify</phase> <goals> <goal>sign</goal> </goals> </execution> </executions> </plugin>

this causes travis build fail - apparently because not have passphrase available while running mvn install. see this build example.

what best way configure maven and/or travis skip gpg signing ci test builds, still perform gpg signing when proper release build?

you need create profile & create sure run when release build.

remove current plugin, , add together in profile this:

<profiles> <profile> <id>release-sign-artifacts</id> <activation> <property> <name>performrelease</name> <value>true</value> </property> </activation> <build> <plugins> <plugin> <groupid>org.apache.maven.plugins</groupid> <artifactid>maven-gpg-plugin</artifactid> <version>1.4</version> <executions> <execution> <id>sign-artifacts</id> <phase>verify</phase> <goals> <goal>sign</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </profile> </profiles>

and when need release, add together property mvn command:

mvn -dperformrelease=true ...

c# - Steps for using Google custom search API in .NET -

i trying utilize google custom search api in .net project. have api key provided company. have created custom search engine using google business relationship , copied 'cx' value.

i using next code:

string apikey = "my company key"; string cx = "cx"; string query = tbsearch.text; webclient webclient = new webclient(); webclient.headers.add("user-agent", "only test!"); string result = webclient.downloadstring(string.format("https://www.googleapis.com/customsearch/v1?key={0}&cx={1}&q={2}&alt=json", apikey, cx, query));

i getting next error: "the remote server returned error: (403) forbidden. "

i have tried next code too:

google.apis.customsearch.v1.customsearchservice svc = new google.apis.customsearch.v1.customsearchservice(); svc.key = apikey; google.apis.customsearch.v1.cseresource.listrequest listrequest = svc.cse.list(query); listrequest.cx = cx; google.apis.customsearch.v1.data.search search = listrequest.fetch(); foreach (google.apis.customsearch.v1.data.result result1 in search.items) { console.writeline("title: {0}", result1.title); console.writeline("link: {0}", result1.link); }

here next exception @ fetch():

google.apis.requests.requesterror access not configured [403] errors [message[access not configured] location[ - ] reason[accessnotconfigured] domain[usagelimits]

is cx parameter required? getting error because using key provided company , using cx parameter custom search engine using google account?
