Error on running an application: java.lang.exceptionininitializererror

Question

I have dowloaded an android app source code, and this is the only activity:

package net.itskewpie.freerdp;

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

public class FreeRDPActivity extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        System.out.println("111111111111111111111");
        String b = test();
        System.out.println(b);

        }

   static{     
       System.loadLibrary("freerdp");
      }
   public native String test();

}

when I try to run it I get this:

08-13 14:15:34.307: W/dalvikvm(335): Exception Ljava/lang/UnsatisfiedLinkError; thrown  while initializing Lnet/itskewpie/freerdp/FreeRDPActivity;
08-13 14:15:34.317: W/dalvikvm(335): Class init failed in newInstance call (Lnet/itskewpie/freerdp/FreeRDPActivity;)

08-13 14:15:34.357: E/AndroidRuntime(335): FATAL EXCEPTION: main
....

What's the problem?

Well it sounds like it can't find the freerdp native library... — Jon Skeet

and what can i do to solve this problem? i have to compile the native library with NDK? they are written in c — SegFault

Add a System.out.println( System.getProperty("java.library.path") ) before the line System.loadLibrary("freerdp");. It will print the paths where java looks for native libraries. Make sure that freerdp (I think it would have a .so extension) resides in one of those places — c.s.

I suggest you consult the freerdp documentation. I have no experience of linking native libraries on Android... — Jon Skeet

The exception ExceptionInInitializerError is a fatal error that is thrown when an unchecked exception is thrown (and not caught) during static initialization of a class.

The stacktrace indicates that the exception that is being thrown is UnsatisfiedLinkError. This is most likely being thrown because:

the runtime cannot find the native code library freerdp, or
the library is not defining a method implementation that matches the native method declaration FreeRDPActivity.text().

in the folder "include->libfreerdp-core" there is freerdp.c.. i have to compile it before running the app?

Stephen C Over a year ago

@Butterfly89 - Of course you do! Did you read the freerdp build / installation instructions?

SegFault Over a year ago

yes...excuse me,this is the first time i do this and i don't know how to move! i've read something from this page github.com/awakecoding/FreeRDP-Manuals/blob/master/Developer/… ..i've understood that i have to install NDK to do it, right?

I apologize again for the inconvenience!

Assuming that you are trying to cross-compile for Android, the instructions are here: github.com/awakecoding/FreeRDP-Manuals/blob/master/Developer/…. I can't help you further.
