and gradle file is:

    import com.android.build.gradle.tasks.packageapplication  buildscript {     repositories {         mavencentral()     }     dependencies {         classpath 'com.android.tools.build:gradle:1.2.3'     } } apply plugin: 'com.android.application'  repositories {     mavencentral() }  dependencies {     compile 'com.nineoldandroids:library:2.4.0'     compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'     compile 'com.android.support:support-v4:22.1.1'     compile filetree(dir: 'libs', include: '*.jar') }  android {     compilesdkversion 19     buildtoolsversion '19.1.0' /*     signingconfigs {         release {             storefile file(system.console().readline("\n\$ enter keystore path: "))             storepassword system.console().readline("\n\$ enter keystore password: ")             keyalias system.console().readline("\n\$ enter key alias: ")             keypassword system.console().readline("\n\$ enter key password: ")         }     }      buildtypes {         release {             signingconfig signingconfigs.release         }     } */     getndkdirectory()      defaultconfig {         minsdkversion 10         targetsdkversion 22     }     sourcesets {         main {             manifest.srcfile 'androidmanifest.xml'             java.srcdirs = ['src']             resources.srcdirs = ['src']             aidl.srcdirs = ['src']             renderscript.srcdirs = ['src']             res.srcdirs = ['res']             assets.srcdirs = ['assets']         }          instrumenttest.setroot('tests')     }     buildtypes {         debug {             debuggable true             jnidebuggable true         }     } }    /*  * jni hack gradle - works alright, copies native libs on build folder no problem  * https://gist.github.com/khernyo/4226923  */  task copynativelibs(type: copy) {     from(new file('libs')) { include '**/*.so' }     new file(builddir, 'native-libs') }  tasks.withtype(javacompile) { options.encoding = "utf-8" }  clean.dependson 'cleancopynativelibs'  tasks.withtype(packageapplication) { pkgtask ->     pkgtask.jnifolders = new hashset<file>()     pkgtask.jnifolders.add(new file(projectdir, 'native-libs')) }

i trying load files like:

static {     system.loadlibrary("nativeaudio"); }

i receive following error: 

java.lang.unsatisfiedlinkerror: couldn't load plumble loader dalvik.system.pathclassloader[dexpathlist[[zip file "/mnt/asec/com.morlunk.mumbleclient-1/pkg.apk"],nativelibrarydirectories=[/mnt/asec/com.morlunk.mumbleclient-1/lib, /vendor/lib, /system/lib, /system/lib/arm]]]: findlibrary returned null

i tried many refrences unable solve issue. using android studio , gradle version: 1.2.3

unlike eclipse adt, gradle android plugin looks native libraries in src/main/jnilibs folder default.

you can change folder location in following source set:

android {     sourcesets.main {         jnilibs.srcdir 'src/main/libs'     } }

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
