Java Reflection getting message from WhatsApp by inner class on Android Notification -

i´m looking way messages whatsapp notifications when there more 1 line.

i´m trying value private variable inside inner class via reflection in android. i´m trying 'mtexts' arraylist of charsequence used build inboxstyle notification. i´m looking messages whatsapp since last whats update there no on notifications listened notificationlistener() have multiple lines notification (i can first line).

any way lines worth it.

this code.

@override     public void onnotificationposted(statusbarnotification sbn) {         super.onnotificationposted(sbn);       class[] declaredclasses = sbn.getnotification().getclass().getclasses();          (class c : declaredclasses){              if(c.getname().contains("notification$inboxstyle")){                 class inboxstyleclass = c.getclass();                  field[] fields = inboxstyleclass.getdeclaredfields();                  for(field field : fields){                      if(field.getname().contains("mtext")){                          field fmtext = null;                         try {                             fmtext = inboxstyleclass.getdeclaredfield("mtexts");                         } catch (nosuchfieldexception e) {                             e.printstacktrace();                         }                          arraylist<charsequence> mtextsarraylist = null;                          fmtext.setaccessible(true);                          try{                             mtextsarraylist = (arraylist<charsequence>) fmtext.get(**wich object may use here**);                         }catch(illegalaccessexception e){                             e.printstacktrace();                         }                          for(charsequence value : mtextsarraylist){                             log.i("xxx","results are: "+value.tostring());                         }                     }                 }              }          }  } 

i reach mtext field correctly can´t value it.

i tried use new notification.inboxstyle() object

 notification.inboxstyle istyleobjecttogetthevalue = new notification.inboxstyle(); 

to see if works well, , does

inboxstyle = (arraylist<charsequence>) fmtext.get(istyleobjecttogetthevalue); 

but need values notification. idea on how can achieve that?

i tried message lines inflating remoteviews can retrieve statusbarnotification.getnotification().the_remote_view because using devicemonitor can take screenshoot of device , see ids of views... had no lucky that.

any way lines worth it.

all welcomed!! thanks!!

according docs remoteview.apply():

view apply(context context, viewgroup parent) - inflates view hierarchy represented object , applies of actions.

you can create parent , provide context remoteview.apply(). inspect resulting view find text:

@nullable public view getbigcontentview (statusbarnotification statusbarnotification) {     remoteviews bigcontentview = statusbarnotification.getnotification().bigcontentview;     return bigcontentview != null ? bigcontentview.apply(ctx, null) : null; } 

this might not work in nougat phones, according documentation (reading more tells me google did not mean read parameter , should used when building notification):

 * of n, field may null. expanded notification view determined  * inputs {@link notification.builder}; custom remoteviews can optionally  * supplied {@link notification.builder#setcustombigcontentview(remoteviews)}.
