[android-developers] Problems to access to Android Screenshot Library from an IntentService

[Jonathan Chacón Barbero]

Hello,



I am still developing an App to take screenshots from a service in background. 
I decided to install Android Screenshot library from ADB.
But now the problem is this:

When I try to connect to Android Screenshot library (AsL) from an IntentService 
using this code I get a null pointer exception:
try {
bindService (new Intent(pl.polidea.asl.ScreenshotService.BIND), aslServiceConn, 
Context.BIND_AUTO_CREATE);
} catch (Exception e) {
Log.e(TAG, e.toString());
}

How can I access to a Bind service from an Intent service?

Regards
Jonathan Chacón

 If you can do it from a computer with AndroidViewClient/culebra 
 (https://github.com/dtmilano/AndroidViewClient 
 https://github.com/dtmilano/AndroidViewClient) installed, `culebra` could 
 generate a script for you that would look like (I've just edited it and added 
 the while):

 Hello, 
 
 I need to take a screenshot each four seconds and I thought to develop a 
 service with a timer to take the screenshot but I don't know how to take the 
 screenshot with a not root device. 
 
 I found ASL (Android Service Library) but I don't know how to include it to 
 install and start ASL from my App. 
 
 Any suggestion please?
