How to make text appear in an android notification? -

-

i trying create notification on android in order notify user if happening. here example code (called mainactivity)

notificationcompat.builder mbuilder =             new notificationcompat.builder(this)             .setsmallicon(r.drawable.stoxx_icon)             .setcontenttitle("my notification")             .setcontenttext("hello world!"); intent resultintent = new intent(this, mainactivity.class);  taskstackbuilder stackbuilder = taskstackbuilder.create(this); stackbuilder.addparentstack(mainactivity.class); stackbuilder.addnextintent(resultintent); pendingintent resultpendingintent =             stackbuilder.getpendingintent(                 0,                 pendingintent.flag_update_current             ); mbuilder.setcontentintent(resultpendingintent); notificationmanager mnotificationmanager =         (notificationmanager) getsystemservice(context.notification_service); int mid = 1001; mnotificationmanager.notify(mid, mbuilder.build());

the notification shown on screen (no lock screen, normal un-locked screen) , when swipe notification bar down (like figure 2 in documentation) can see well, text follows: 

myapplication contents hidden

i expecting see following content: 

my notification hello world!

i looked in documentation did not find can use solve problem(i looked @ setvisibility, seems relevant lock-screen not have here). maybe overlooked it, maybe nothing have notification. idea how solve problem?

setting setvisibility(notificationcompat.visibility_public) makes text readable on lock screen (not want) , setvisibility(notificationcompat.visibility_secret) not show notification on lock screen @ all.

what want:

  • lock-screen: notification shown 'contents hidden'
  • unlocked screen: notification shown content given in code.

what visibility_private:

  • lock-screen: notification shown 'contents hidden'
  • unlocked screen: notification shown 'contents hidden'

what visibility_public:

  • lock-screen: notification shown with content given in code.
  • unlocked screen: notification shown with content given in code.

what visibility_secret:

  • lock-screen: notification not shown @ all.
  • unlocked screen: unknown

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
