android - fade in and out music while speaking a text -

-

I have an Android application that uses TTS (Text to Speech) API, everything is working perfectly But now I want to stop music (like the user playing music with the music) in or out, or even when the app speaks a text right now, I think both music and TTS messages are sent to the same stream (music) ), And understanding voice messages is important The Kil be.

I have tried to run the text on a different stream, such as audio manager. STREAM_NOTIFICATIONS stops this music, but when the text is spoken, it does not come back, so I did not achieve the goal. Nothing has been received so far, so I hope someone can help here. Thanks!

Whatever the last thing I'm doing though is not true, in case of a fairly dirty trick. Can help someone:

It is fixed with requestAudioFocus and AudioManager's abandomAudioFocus methods on ADI 8.

But for pre-versions, you can try to run TTS through a different stream channel, say STREAM_NOTIFICATIONS, then you just have to return the audio focus to STREAM_MUSIC how you can get it ? To send a silent string ("") to TTS but this time there will be an effect through STREAM_MUSIC: the music is closed, your TTS will speak the message, and in the end your music will come back after the sound alert. Not good or something to feel proud of, but ... if someone knows differently, I appreciate it.

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

-
I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
