"No media found". How to insert image in android -

-

I'm new to Android programming so if someone helps me then I would be really grateful

I am trying to implement Steganography in Android but my problem is that I do not know how to insert images in Android. That's why I'm getting "no media was found" . Please help me with it.

I tried

c: & gt; Adb push c: \ image1.png /sdcard/image1.png

But I get this command prompt.

failed to copy 'c: The correct directory for my emulator is mnt / sdcard . It works for me: 

  adb push README mnt / sdcard   
 Also keep in mind that you  adb shell ls & lt; Path & gt; , which may be sent to you on the right track  
  edit  - apparently  sdcard  to  mnt / sdcard  and also works for me using the named file Doing  image1.png  is also working. Maybe you have a problematic file already on that place?  
  Edit  - I think you have to turn off the USB mounting option when you will use ADB to push files. It seems that your comment about the gallery is not searching for your media.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
