android - Returning Imageuri=null (but data extras) from camera capture -


while debugging below code, getting value of picuri null , can see picuri=null data:"intent" {act=inline-data (has extras)}" in trace. why picuri not having corresponding uri , have data extras?

public void onclick(view v) {         if (v.getid() == r.id.capture_btn) {             try {                 // use standard intent capture image                 intent captureintent = new intent(                         mediastore.action_image_capture);                 // handle returned data in onactivityresult                 startactivityforresult(captureintent, camera_capture);             } catch (activitynotfoundexception anfe) {                 toast toast = toast.maketext(this, "this device doesn't support crop action!",                         toast.length_short);                 toast.show();             }         }     }      protected void onactivityresult(int requestcode, int resultcode, intent data) {         if (resultcode == result_ok) {             if (requestcode == camera_capture) {                 // uri captured image                 picuri = data.getdata();                                         }                  } }

  1. here pass camera intent

    private void intentcamera() { intent cameraintent = new intent(mediastore.action_image_capture); startactivityforresult(cameraintent, camera_request); }
  1. and after captured image
protected void onactivityresult(int requestcode, int resultcode, intent data) {   if (requestcode == camera_request && resultcode == result_ok) {     bitmap photo = (bitmap) data.getextras().get("data");      imageview.setimagebitmap(photo);     knop.setvisibility(button.visible);       // call method uri bitmap     uri tempuri = getimageuri(getapplicationcontext(), photo);      // call method actual path     file finalfile = new file(getrealpathfromuri(tempuri));      log.e("resultcapturedimage-->",mimagecaptureuri); }    }  public uri getimageuri(context incontext, bitmap inimage) { bytearrayoutputstream bytes = new bytearrayoutputstream(); inimage.compress(bitmap.compressformat.jpeg, 100, bytes); string path = images.media.insertimage(incontext.getcontentresolver(),  inimage, "title", null); return uri.parse(path); }  public string getrealpathfromuri(uri uri) { cursor cursor = getcontentresolver().query(uri, null, null, null, null);  cursor.movetofirst();  int idx = cursor.getcolumnindex(mediastore.images.imagecolumns.data);  return cursor.getstring(idx);  }

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
