import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class HelloNeon extends Activity
{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        /* Create a TextView and set its content.
         * the text is retrieved by calling a native
         * function.
         */
        TextView  tv = new TextView(this);
        tv.setText( stringFromJNI() );
        setContentView(tv);
    }

    /* A native method that is implemented by the
     * 'helloneon' native library, which is packaged
     * with this application.
     */
    public native String  stringFromJNI();

    /* this is used to load the 'helloneon' library on application
     * startup. The library has already been unpacked into
     * /data/data/com.example.neon/lib/libhelloneon.so at
     * installation time by the package manager.
     */
    static {
        System.loadLibrary("helloneon");
    }
}

On the screen when i run i get error:

"Sorr! The application HelloNeon (process com.example.neon) has stopped unexpectedly. Please try again."

Answer 1

I guess the error is "The application HellowNeon (process com.example.neon) has stopped unexpectedly Please Try again :-)". So you can

Filter your log to just Error and look for FATAL EXCEPTION

Also You can debug by setting breakpoints in Eclipse.Select "Debug" rather than the standard "Run", which will allow you to step through and so on.
