How to get a list of all apps installed on a Symbian device

Comments

One small bug:

If application UID begin with char (a/b/c/d/e/f) then output UID printed to file begin with "ffffffff" prefix.

Example, original uid e602d449 - in file we have ffffffffe602d449

Solution:

replace

buf.AppendNum(aInfo.iUid.iUid, EHex);

with

buf.AppendNum((TUint)appInfo.iUid.iUid, EHex);

Description

The following code creates a text file containing a list of all applications and their UID values. It can be run on any Symbian OS phone.

Solution

 #include <f32file.h>    // link against efsrv.lib
 #include <apgcli.h>     // link against apgrfx.lib, apparc.lib
 
 _LIT(KFileName, "c:\\applications.txt"); 
 const TInt KMaxSize = 512;
 
 LOCAL_C void WriteAppInfoToFileL()
   {
   RFs fs;
   RFile file;
   RApaLsSession lsSession;
 
   // Connect to file server
   User::LeaveIfError( fs.Connect() );
   CleanupClosePushL( fs );
 
   // Connect to application architecture server
   User::LeaveIfError( lsSession.Connect() );
   CleanupClosePushL( lsSession );
 
   // Open (replace if exists) the file for writing
   file.Replace( fs, KFileName, EFileWrite | EFileStreamText );
   CleanupClosePushL( file );
 
   TApaAppInfo appInfo;
   TBuf<KMaxSize>  buf;
   TBuf8<KMaxSize> fileBuf;
 
   // Get info on all apps, then iterate through each app  
   // and write its info (caption, name, uid) to file
   lsSession.GetAllApps();  
   while( lsSession.GetNextApp( appInfo ) == KErrNone )
     {
     buf.Zero();
     buf.AppendNum( (TUint)aInfo.iUid.iUid, EHex );
     buf.Append( _L("\t") );
     buf.Append( appInfo.iCaption );
     buf.Append( _L("\t") );
     buf.Append( appInfo.iFullName );
     fileBuf.Copy( buf );
     fileBuf.Append( _L("\n") );
     file.Write( fileBuf );
     }
 
   CleanupStack::PopAndDestroy( 3 ); // file, lsSession, fs
   }
