permissions - Android 6 Error in Reading Device ID? -


while reading device id etc. getting error in android 6.

how ever working fine in other versions 4.0,5.1 etc..

this code:

public class mydevids extends appcompatactivity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          setrequestedorientation(activityinfo.screen_orientation_nosensor);          packageinfo pinfo = null;         try {             pinfo = getpackagemanager().getpackageinfo(getpackagename(), 0);         } catch (namenotfoundexception e) {             e.printstacktrace();         }         string version = pinfo.versionname;         textview versiontext = (textview) findviewbyid(r.id.tv7);         versiontext.settext("version  : " + version);          telephonymanager telephonymanager = (telephonymanager) getsystemservice(context.telephony_service);         string imei_id = telephonymanager.getdeviceid();         textview imei_idt = (textview) findviewbyid(r.id.tv9);         string imei_idv = "<b><font color=#008000>" + imei_id + "</b></font>";         imei_idt.settext(html.fromhtml("imei id  : " + imei_idv));          string device_id = settings.secure.getstring(getcontentresolver(), settings.secure.android_id);         textview device_idt = (textview) findviewbyid(r.id.tv10);         string device_idv = "<b><font color=#008000>" + device_id + "</b></font>";         device_idt.settext(html.fromhtml("device id  : " + device_idv));     }  }

this error getting

java.lang.runtimeexception: unable start activity componentinfo{com.test.devid/com.test.devid.mydevids}: java.lang.securityexception: getdeviceid: neither user 10102 nor current process has android.permission.read_phone_state.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
