javah

在eclipse中建一项目，建一class，即TestHello.java文件 1 package esmart.colfile.parse 3 public class TestHello { 4 static { 5 System.loadLibrary( " TestHello " ); 6 } 8 public static native void hello(String msg); 10 public static void main(String[] args) { 12 hello( " Hello,Kimm! " ); 14 } 15 } 往往报如下的错误，就是因为shell命令的格式不对，应该严格按照我下面描述的格式来写，尤其注意第二步第三句的点和空格，就不会出错了。 错误： 无法访问 esmart.colfile.parse.TestHello 找不到文件 esmart.colfile.parse.TestHello.class javadoc: 错误 - 找不到类 esmart.colfile.parse.TestHello。 Error: 未在命令行中指定任何类。请尝试使用 -help 打开cmd命令框，输入shell命令，按照如下顺序输入 : 第一步 ：进入TestHello.java文件的上级目录，编译该文件，则能在G:\work\eclipse

Hi guys i am using android ndk and for that i am trying to create a c header file using javah tool how to use and where to use this tool i am unable to understand so please any one can tell me the procedure how to do that i am waiting for the reply please......... Javah should be in the bin folder of your JDK Something like this: C:\Program Files\Java\jdk1.6.0_19\bin For simplicities sake take the path name folder from the bin directory in your Android project and place it in the above directory. Then use the command prompt javah -jni com.pathname.ClassName And the header file will be created

I've just wasted 2 hours trying to do something which I've already done twice before. I can't remember the exact procedure I used the previous two times, but it really shouldn't be giving me this much trouble: I have a project folder called "BoardGUIv3". I want to produce a header file based on a class called "CANController", with the source located in "BoardGUIv3/src/model" and the class file in "BoardGUIv3/bin/model". I've done exactly this thing before, but for some reason I can't seem to do this simple, one-line command again. I'm pretty sure it's something along the lines of javah

I have a simple class for use on JNI, which i need to export to a header file (.h). I've read that I need to use the javah command, by going to the src folder of the project, and type: javah -jni com.main_package.NativeClass On windows it works fine, but on my main OS (Linux) it doesn't. It keeps telling that it can't find the class. I've tried to use many combinations of the command and to run it on many possible paths, but it didn't work. I've followed many tutorials and websites (including here) and tried their combinations too. I even tried using Eclipse's external tool for this, as shown

I am following this tutorial on how to use NDK with Android Studio: http://www.ph0b.com/android-studio-gradle-and-ndk-integration/ I have android studio 0.9.3 installled on windows 8, and i follow each step of the tutorial in the video, and at the step to generate jni folder i do this in the android studio's terminal : D:\ANDROID\workspace\NDKSample\app\src\main>javah -d jni -classpath D:\ANDROID\kits\sdk\platforms\android-19\android.jar;D:\ANDROID\workspace\NDKSample\app\build\intermediates\classes\debug com.jihv.gildas.ndksample.MainActivity and I have this error : Error: cannot access
