HelloJNI Android'java.lang.UnsatisfiedLinkError：stringFromJNI'

Question

I googled a lot for a solution for my problem but I have found anything that helped me. I am an Android beginner and have problems with the HelloJNI sample from the Android NDK.

I work with Eclipse and put the hello-jni.c file as well as the Android.mk in the jni/ folder of my Android project. Then I put the Hellojni.java file into the src/ folder in a package. I can build the code with the ndk-build tool. So I get the hello-jni.so file which is put into libs/armeabi .

Everything seems to be fine. In the main activity of the Android project, I can create an object of Hellojni like Hellojni x = new Hellojni(); . But when I try to open the function stringFromJNI like x.stringFromJNI(); the error occurs which I wrote in the title of this topic.

Is there anything wrong? Unfortunately the source code of the project is on another computer so that it is difficult to put it here. But I could try to do that in case you need it to give me a hint. Thanks in advance.

你有这样称呼本地图书馆吗？

System.loadLibrary("hello-jni.so");
