Accessing native library code from rho elements application

Bhoomesh gupta Mar 29, 2013 8:36 AM

Hello All,

I have one issue and one question while working with native extension + native library(.jar) file

Issue#1

We added native (.jar) library and able to compile rho elements application.

While we are creating new object from library we are getting following runtime exception :

“java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()”

Can anyone faced this problem? If so, how did you approached to solve?

Qustion#1

How to get native android UI reference in native extension. Do we need to use “com.rhomobile.rhodes.RhodesActivity” or something else?

I have situation that, i need to display an alert during application sleep/wake through native extension.

Hi,

To run in UI thread you may use com.rhomobile.rhodes.util.PerformOnUiThread.exec(Runnable r) util.
In order to access UI Context object use com.rhomobile.rhodes.util.ContextFactory.getUiContext() util.

  Thanks Alexey,
  
  I haven't check with above API's you mentioned. I will check with above API's and let you know the results..
  Do you know, where can i find rhomobile android API's documentation? I found below link for source code
  https://github.com/rhomobile/rhodes/tree/master/platform/android/Rhodes/src/com/rhomobile/rhodes
  But, i did not find any documentation at above link.
  Documentation at below link has all Ruby API's not Android native API's.
  http://docs.rhomobile.com/rhodesapi/rhoutils-api. Could you please suggest us.
  
  Thanks,
  Bhoomesh

    Unfortunately there is no documentation for Rhodes internal native API.
    You may just look rhodes sources.

  import com.rhomobile.rhodes.util.PerformOnUiThread;
  
  PerformOnUiThread.exec(new Runnable(){
  @Override
  public void run() {
  //Your method here..
  }
  });
