and

public class frontpageactivity extends activity { private static final string number = "number"; private static final string my_pref = "mypref"; private static final string na = "na"; private imageview imageview; private string enteredphonenumber; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_frontpage); bitmap bitmap = getintent().getparcelableextra("mapphoto"); if (bitmap != null) { imageview.setimagebitmap(bitmap); } getenteredphonenumber(); button callbutton = (button) findviewbyid(r.id.callbutton); this.imageview = (imageview) this.findviewbyid(r.id.pictureimageview); callbutton.setonclicklistener(makephonecall); } public void gotocamera(view v) { intent intent = new intent(this, cameraactivity.class); startactivity(intent); } private void getenteredphonenumber() { sharedpreferences sharedpref = getsharedpreferences(my_pref, mode_private); enteredphonenumber = sharedpref.getstring(number, na); } private onclicklistener makephonecall = new onclicklistener() { @override public void onclick(view v) { intent callintent = new intent(intent.action_call); callintent.setdata(uri.parse("tel:18181818," + enteredphonenumber)); startactivity(callintent); } }; }

i hope can spot error, because can't.

it might problem image size taken camera. if image size more cannot image activity in intent.

once seek limit size of image next while making photographic camera request.

intent cameraintent = new intent(android.provider.mediastore.action_image_capture); cameraintent.putextra( android.provider.mediastore.extra_size_limit, "720000"); startactivityforresult(cameraintent, camera_request_idphoto);
