android set image as contact icon/wallpaper -

-

I have written my own imageviewer and now I have the set as functionality in the Android country . image viewer. Now this is possible because Facebook has it. I have attached a screenshot to make myself more clear Enter image details here

PS I want to give a more detailed description of what happened wrong. After selecting the "Contact icon" in the menu, a list of my contacts appears, when I select a contact, the application stops the force. If I choose "home / lock screen wallpaper" then it opens my phone gallery. Here is my code snippet: 

  Bitmap icon = mbitmap; Intent setAs = new intent (Intent.ACTION_ATTACH_DATA); SetAs.setType ("image / jpg"); BytereonOperputsTream Bytes = New ByteOrthroughs (); Icon.compress (bitmap compoforat.jpg, 100, bytes); File f = new file (environment .getExternalStorage directory () + file. Separator + "/my_tmp_file.jpg"); Try {F.createNewFile (); FileOutputStream fo = New FileOutputStream (f); Fo.write (bytes.toByteArray ()); } Hold (IOException e) {e.printStackTrace (); } SetAs.putExtra (Intent.EXTRA_STREAM, Uri.parse ("File: ///sdcard/my_tmp_file.jpg")); Initial Activity (Intent.createChooser (setAs, "Set as Image"));   
 I have also added the result permissions for my manifest and I am able to write my image in the phone's SD card.  
 Logcat Output   
 
 
:  
  // is called when click on "Set as". Private stationary Boolean on STAsolved (menu incakara on invoke, last activity activity) {onInvoke.run (new menu callback) {public zero-zero (Yuri U, IIIM image) {if (U == blank} image == empty) {Return;} intent to intent = uTil.CreateCatAsIntent (image); activity.art activity (intent .createchor (intent, activity.gate text) (R. string .seetmage)));}}); Back true; }

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...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
