[android-developers] Re: getExternalStorageDirectory() on NEXUS S
It's forced into the built-in space that will get picked up by the Android media scanner when it indexes EXTERNAL_CONTENT_URI. btw I don't think the media scanner picks it up. The media scanner would need to be explicitly told to look at '/mnt/emmc' On Jan 4, 12:45 pm, Tabman tabishfay...@gmail.com wrote: Thanks Doug, Your reply is very helpful, you also replied to another post of mine so thanks again :) On Dec 20 2010, 1:51 am, Doug beafd...@gmail.com wrote: On Dec 19, 2:14 pm, Tabman tabishfay...@gmail.com wrote: I have a question related to this.

However, it works on Galaxy S devices because its built-in external space is wired to that URI --AND-- if you do have a sdcard in the device, it will mount THAT filesystem underneath the internal storage space. So if the internal storage space was at /mnt/sdcard, your additional sdcard would be at /mnt/sdcard/external_sd. And when the Android media scanner runs to index media referenced by EXTERNAL_CONTENT_URI, it will scan all of /mnt/sdcard, including the sdcard. So they're doing it in a more compatible way that lets you get at the media on the user's sdcard in addition to the built-in space. I don't know what the Nexus S or HTC Hero do. I also don't know what this Picasa Tool Pro does. Maybe it doesn't query against the Android content providers for media and does its own thing instead.

[android-developers] Re: getExternalStorageDirectory()
Actually, use: File pathDir = Environment.getExternalStorageDirectory(); That is, don't use toString() unless and until you actually need it. A File object is more useful. Don't perform string operations to construct file paths. For example, write File logDir = new File(pathDir, logg); logDir.mkdirs(); File logFile = new File(logDir, generateLogDirName()); OutputStream logStream = new FileOutputStream(logfile); BufferedWriter logWriter = new BufferedWriter(new OutputStreamWriter(logStream, UTF-8)); No toString() method needed -- wanted!
