-

Hello I am new to Android. I am developing an application with alarm functionality here to give me sound fade in functionality I'm using media player to open ringtone for alarm. Here is my code for playing alarm sound 

  try {if (mp == null) {System.out.println ("------- mp" is now zero - -------- "); Uri Mayuri = Uri.Pars ("android.resource: //com.android.crazy/raw/airtel"); Mp = MediaPlayer.create (alarm. This, myURI); } Mp.setDataSource (songName); Mp.prepareAsync (); Mp.setLooping (true); } Hold (exception e) {e.printStackTrace (); } Mp.start ();   
 Here I have to give sound Fadin functionality Please advise me how to insert sound fade for any particular amount like 5 minutes  
 Thanks in advance  < / Div> 
 
 
 You can use this method:  
  set volume (float left volumes, right volume Float);   
 To create a "feed in" effect, you will just start with zero and keep it at a slightly higher interval. In this way, some things will increase the volume of half to 5% of each other  
  last handler H = new handler (); Float leftVol = 0f; Float right = 0f; Runnational enhancement = new Runnabal () {Public Zero Run () {mp.setVolume (leftVol, rightVol); If (leftVol> 1.0f) {leftVol = .05f; RightVol + = .05f; H.postDelayed (Growth, 500); }}}; H.post (increaseVol);   
 If you change into the remaining wov and right wal then how much each tick can be increased if inside the statement.    and how long you can change each tick by changing 500 parameters in the post.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
