unsatisfiedlinkerror

We have this app that loads native library, and this library provides native methods for us to call. On some phones (particularly the slower ones), this causes a problem. An UnsatisfiedLinkError occurs whenever (I think) the library is still being "loaded" and a method is called prematurely. Is there a way to handle this issue? Like checking if a library is already loaded. Even on slower devices, the call to System.loadLibrary() is very fast; but if your app runs multithreaded, or if the class that involves the static constructor is only loaded in response to some UI event - then there could

I have java program Client.class that uses cpp shared library libclient.so via JNI. libclient.so is built as shared and uses cpp shared library libhttp.so. libclient.so and libhttp.so are placed in folder /home/client/lib64 Client.class is placed in /home/client/bin Client can load library with System.load and environment variable LD_LIBRARY_PATH System.loadLibrary and -Djava.library.path The first way works fine. export LD_LIBRARY_PATH = /home/client/lib64 java -classpath ./bin Client The secon way fails. java -classpath ./bin -Djava.library.path=./../lib64 Client java.lang

Update 8/7/2013: The problem is solved now, but the reason for the error was quite unexpected, all the usual suspects for such errors were eliminated on start, and I have learned something new. See my answer below. I'm pretty desperate here. Have an Android app with a native library, from where I call a method. No problem on all the systems I tested, and the program was out in Google Play without any trouble reports, used by thousands of users. Now, apparently a new ROM - Android version 4.2.2 - for HTC One phone is out. Users claim that it's the official build, upgraded form the official

I am getting experiencing a similar problem to this question: UnsatisfiedLinkError with sqlite4java Jar on Mac OS X However, I am running on a Mac, and I have the relevant libraries in my lib folder. However, if I run this as is I get the UnsatisfiedLinkError. If I run "java -jar sqlite4java.jar -d" I get the following output: sqlite4java 282 130321:222850.424 FINE [sqlite] Internal: loading library 130321:222850.425 FINE [sqlite] Internal: java.library.path=/Users/mikey/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib

I need capture a video stream from my USB webcam, for this i use Opencv 2.4.6 for developing in Java. I follow the steps listed in here I add the "C:\opencv\build\java\x64" dir to my System PATH and include the "opencv-246.jar" file into my libraries on ECLIPSE. When y run the explame import org.opencv.core.Core; import org.opencv.core.CvType; import org.opencv.core.Mat; public class Main { public static void main(String[] args) { System.loadLibrary(Core.NATIVE_LIBRARY_NAME); Mat m = Mat.eye(3, 3, CvType.CV_8UC1); System.out.println("m = " + m.dump()); } } i get m = [1, 0, 0; 0, 1, 0; 0, 0, 1]

just trying to do a simple openCV android program. Downloaded and installed OpenCV for Android following the instructions here and added the OpenCV Library 2.4.2 as a library project for my own android project like the instructions state. However when I compile the standard "Hello World Program", as follows, it fails if I include the Mat mat = new Mat(); line, but succeeds otherwise. package com.example; import org.opencv.core.Mat; import android.app.Activity; import android.os.Bundle; public class HelloAndroidActivity extends Activity { /** Called when the activity is first created. */

In my project I want to capture image from my webcam. I configured step by step following the instructions from this "OpenCV-JavaCV : eclipse project configuration windows 7" blog post . After configuration is finished, i tested samples codes and the application found my webcam SETUP: Setting up device 0 SETUP: Namuga 1.3M Webcam SETUP: Couldn't find preview pin using SmartTee SETUP: Capture callback set SETUP: Device is setup and ready to capture. and then i got an error which is .dll error. I use windows 7 x64. Exception in thread "Thread-2" java.lang.UnsatisfiedLinkError: C:\Users
