Android Studio opencv C++ compile link libraries error at runtime -


i'm using android studio 1.3.2 gradle 2.6 experimental ndk.

this error:

dlopen("/data/app/face.rt.jeanc.facert-2/lib/arm/libface.so", rtld_lazy) failed: dlopen failed: "/data/app/face.rt.jeanc.facert-2/lib/arm/libface.so" has unexpected e_machine: 40

also, lib face should appears libface.so in folders (armabi, armabi-v7, etc) doesn't appear (compile ?)

here build.gradle:

apply plugin: 'com.android.model.application'  model {     android {         compilesdkversion = 23         buildtoolsversion = "23.0.1"          defaultconfig.with {             applicationid = "face.rt.jeanc.facert"             minsdkversion.apilevel = 19             targetsdkversion.apilevel = 19             versioncode = 1             versionname = "1.0.1"         }      }      android.buildtypes {         release {             minifyenabled = false             proguardfiles += file('proguard-rules.txt')         }     }      android.ndk { // keeping make correctly support c++ code editing , debugging         modulename = "face"         ldlibs += ['log']         cppflags += "-std=c++11"         cppflags += "-fexceptions"         cppflags += "-i${file("src/main/jni/prebuilts/include")}".tostring()         cppflags  += "-i${file("c:/android-dev/sdks/opencv-android-sdk/sdk/native/jni/include")}".tostring()         cppflags  += "-i${file("c:/android-dev/sdks/opencv-android-sdk/sdk/native/jni/include/opencv")}".tostring()         cppflags  += "-i${file("c:/android-dev/sdks/opencv-android-sdk/sdk/native/jni/include/opencv2")}".tostring()         ldlibs += ["android", "egl", "glesv2", "dl", "log", "z"]// , "ibopencv_core"          stl = "gnustl_shared" //"stlport_static"     }       android.productflavors {     // detailed abifilter descriptions, refer "supported abis" @     // https://developer.android.com/ndk/guides/abis.html#sa     create("arm") {             ndk.with {                 abifilters += "armeabi"                  file curdir = file('./')                 curdir = file(curdir.absolutepath)                 string libsdir = curdir.absolutepath+"\\src\\main\\jnilibs\\armeabi\\" //"-l" +                  ldlibs += libsdir + "libnative_camera_r4.3.0.so"                 ldlibs += libsdir + "libopencv_contrib.a"                 ldlibs += libsdir + "libopencv_core.a"                 ldlibs += libsdir + "libopencv_highgui.a"                 ldlibs += libsdir + "libopencv_imgproc.a"                 ldlibs += libsdir + "libopencv_info.so"                 ldlibs += libsdir + "libopencv_java.so"                 ldlibs += libsdir + "libopencv_legacy.a"                 ldlibs += libsdir + "libopencv_ml.a"                 ldlibs += libsdir + "libopencv_ts.a"              }         }         create("armv7") {             ndk.with {                 abifilters += "armeabi-v7a"                  file curdir = file('./')                 curdir = file(curdir.absolutepath)                 string libsdir = curdir.absolutepath+"\\src\\main\\jnilibs\\armeabi-v7a\\" //"-l" +                  ldlibs += libsdir + "libnative_camera_r4.3.0.so"                 ldlibs += libsdir + "libopencv_contrib.a"                 ldlibs += libsdir + "libopencv_core.a"                 ldlibs += libsdir + "libopencv_highgui.a"                 ldlibs += libsdir + "libopencv_imgproc.a"                 ldlibs += libsdir + "libopencv_info.so"                 ldlibs += libsdir + "libopencv_java.so"                 ldlibs += libsdir + "libopencv_legacy.a"                 ldlibs += libsdir + "libopencv_ml.a"                 ldlibs += libsdir + "libopencv_ts.a"              }         }          create("x86") {             ndk.with {                 abifilters += "x86"                  file curdir = file('./')                 curdir = file(curdir.absolutepath)                 string libsdir = curdir.absolutepath+"\\src\\main\\jnilibs\\x86\\" //"-l" +                  ldlibs += libsdir + "libnative_camera_r4.3.0.so"                 ldlibs += libsdir + "libopencv_contrib.a"                 ldlibs += libsdir + "libopencv_core.a"                 ldlibs += libsdir + "libopencv_highgui.a"                 ldlibs += libsdir + "libopencv_imgproc.a"                 ldlibs += libsdir + "libopencv_info.so"                 ldlibs += libsdir + "libopencv_java.so"                 ldlibs += libsdir + "libopencv_legacy.a"                 ldlibs += libsdir + "libopencv_ml.a"                 ldlibs += libsdir + "libopencv_ts.a"             }         }         create("mips") {             ndk.with {                 abifilters += "mips"             }         }         create("fat") {          }     } }  dependencies {     compile filetree(include: ['*.jar'], dir: 'libs')     compile 'com.android.support:appcompat-v7:23.0.1'     compile project(':opencvlibrary2411') }

this part of code "should" load different libraries:

////// jni c++ static {system.loadlibrary("face");}  //externals c++ libraries static {system.loadlibrary("libnative_camera_r4.3.0.so");} static {system.loadlibrary("libopencv_contrib.a");} static {system.loadlibrary("libopencv_core.a");} static {system.loadlibrary("libopencv_highgui.a");} static {system.loadlibrary("libopencv_imgproc.a");} static {system.loadlibrary("libopencv_info.so");} static {system.loadlibrary("libopencv_java.so");} static {system.loadlibrary("libopencv_legacy.a");} static {system.loadlibrary("libopencv_ml.a");} static {system.loadlibrary("libopencv_ts.a");}

i'm kinda stuck , need help.

edit: in version of android studio , experimental plugin don't have android.mk file compile jni c++. wondering if or have compile manually ?

if manually how do since don't have android.mk ?

your build succeed, don't copy shared libs opencv libs directory of app. follow advice in how use opencv in android studio using gradle build tool?

note possible combine full power of android.mk experimental plugin: see define local_src_files in ndk{} dsl.

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
