Hi,

Your article is very helpful. But I am not able to build the application properly.
I have created the jni code as explained in the \"apps\" dir. and the application is in /home/abc/workspace.

When i run the application thru eclipse on emulator, i get the error \"The aaplication Jni Sample has stopped unexpectedly.Please try again\".
and when i see the logcat, i found \"Exception Ljava/lang/UnsatisfiedLinkError; thrown during Lcom/msi/linuxmagazine/jnidemo/Hello;.\" message.

I think the System.loadLibrary() can not locate the library properly.
Can you please tell me if i have missed any step?

Thanks in advance!

Hi,
Very useful information. I could develop my own libraries and successfully created applications using those libraries.

Now i want to move more deep into Native code development. My sample library method is trying to read from /dev/dsp and write to a file in SDCard. To write in to SDCard file we have to specify (something like this) in android manifest. But not able to open /dev/dsp.
How can i access the a/dev/dsp file in my native code library method??
