Free PowerPoint Openoffice Remote is an Android app that will allow you to control Open Office Presentation or PowerPoint software remotely. There is a .jar file that needs to be installed in your computer for this to work, which means that you also need Java in your computer as a requirement.
This won’t be useful to most users but to those of us who have a SD card that is either no longer recognized by the phone for some reason or just plain doesn’t work anymore, this will help.
I’m going to show you how to mount your phone’s /cache partition as your /sdcard partition, allowing the use of apps and widgets that require an SD card to work properly. A basic knowledge of ADB and Linux commands will be helpful but not entirely necessary, you should be able to just copy and paste the commands. This could be adapted to mount any writable partition as the SD card partition, such as using /data instead of /cache, which should allow a bit more information because of partition restrictions.
Things you will need:
* (optional) Terminal Emulator installed on your device.
I’ll try to explain the steps as best as I can while keeping the commands readable.
1: Boot into the main Android OS /*this is fairly obvious;
2: Plug your phone into your computer /*again obvious;
3: Open a command prompt/bash/terminal window /*we will by typing the commands here;
4: Type “adb devices” without quotes /*start the adb server if it isn’t and list attached devices;
4A: Linux only: type “sudo adb devices” instead and enter your root password /*start adb as root and list devices;
5: If your device is listed type “adb remount” without quotes, if it isn’t make sure you have usb debugging enabled and try again /*mount the main system as read/write;
6: (optional) type “adb shell” without quotes. if you prefer type all following commands in Terminal Emulator /*start the shell session for linux commands;
7: type “su” without quotes. You should get a #. If this is your first time using TE you will get a dialog asking you to allow su permissions for TE. Click “always allow” or “remember” and “yes” /*get su permissions for shell;
8: type “umount /sdcard” without quotes /*unmount the sdcard, just for good measure;
9: type “mount -o rw,remount /” without quotes /*mount the root filesystem system as read/write;
10: type “umount /sdcard” without quotes /*again,for good measure;
11: type “ln -s cache /sdcard” without quotes /*create a symlink to the /cache partition. now when apps look for /sdcard their data is saved in /cache;
12: Run the app or widget that requires SD card access. It should now work.
This will be undone with a reboot but it should allow you to at least get things working properly. Since this uses the /cache partition it uses the phone’s internal memory, which is very limited so be careful with what you download. This is a temporary fix until a replacement SD card can be obtained. You will still get that annoying notification that you don’t have an SD card inserted but apps and widgets should work just fine with it.
I have noticed that ROM Manager will not work with this method, nor will the camera, but an app called “Weather and Toggle Widgets” will allow you to do an initial setup and continue working even after a reboot. I have obviously not tested each and every app for compatibility but with minor tweaking this could come in handy for much more.
Comment organiser ses écrans sous Android, From HowToGeek.com :
It’s nice to have plenty of applications in our Android phone, until we realize that these applications clutter up our phone by consuming our limited screen space. These are some tips to organize your screen for optimal productivity.
Using Folders to Organize Your Applications
Most Android phones come with 3 to 5 home screens that may not be enough to place all our application shortcuts, but we can use folders to group your home screen shortcuts into some quick pop-up menus.
This is how to create folders on our home screen—tap and hold your home screen for a few seconds to bring up the “Folders” menu.
Select the “New Folder” option from the menu and you should see an empty folder on your screen.
Tap the folder and hold down the folder header to rename it.
Drag the appropriate applications into the folder.
We use the vacation folder to give us quick access to some handy applications that we use when we are travelling with our Android. Maps, Locations, and Navigation are particularly handy when we want to get some direction on the road and KLM currency converter helps us calculate exchange rates on the fly.
Try out the Folder Organizer
Rather than creating folders and putting applications into these folders, we can use Folder Organizer to group our Android applications shortcuts by labeling them. Each shortcut can have multiple labels so that we can assign one application to multiple groups.
The easiest way to install Folder Organizer is by typing “Folder Organizer” into the search text field in Android Market. There are two versions of Folder organizer, the full version that will cost you some money and the lite version that comes for free. We found that the lite version is robust enough to manage the shortcuts on our home screen.
Once installed, Folder Organizer will label some of our applications with its default label—for example, the Folder Organizer will label Angry Birds with “Games”. We can also associate our applications with our own custom label to group them in a folder. Open up the folder organizer screen from your application screen to start assigning labels to your Android applications.
Tap the Labels icon to open up the label screen.
Tap the plus icon to add a new label.
Give the label a proper name. For example, we create da “social networking” label for our social networking software such as Facebook, Twitter, Foursquare, TweetDeck, etc.
Tap the arrow button to bring up the label menu and tap the Items button to assign a label to your applications.
Choose Apps to assign a label to our applications.
We chose to label Foursquare, Google Reader, Mobile Facebook, TweetDeck, and Yammer as our social networking applications.
This is what our social networking folder looks like.
Although we only have a limited number of home screens on our Android, we do have the ability to create folders to group applications according to their context to give us faster access for any occasion.
Minimizing the Need to Swipe Screens
Although we can configure our Android home screen to have up to seven screens, we like to minimize the need to swipe between screens as much as possible by accessing all of our essential application shortcuts from the main screen. If we have used all the available space on the main screen, we can place application shortcuts in the search button or the menu bar.
Doesn’t the search button bring up the search dialog ? Can I put shortcuts in the search button ? The answer to both is “Yes”, with the help of a nifty application called “Quick Settings” that allows us to access the system settings shortcuts through the search button. The easiest way to install Quick Settings is by searching for it through the Android Market.
Hold down your Android “search” button for a few second to bring up the Quick Settings main screen then tap the “menu” button to bring up the customize menu.
Hold down the “Drag Icon” to re-arrange the system settings item that we want to see in Quick Setting’s main screen.
The second place to put shortcuts is the Menu bar using an application called the Smart Bar.
Smart Bar places some useful utilities on your menu bar for quick access. You should see the Smart Bar from your Android application screen once you have installed it through the market.
Tap the Smart Bar icon from the application screen to begin using the Smart Bar features.
Tap the “SmartBar Settings” menu to customize the Smart Bar’s utilities that we want to place on our menu bar. Select the utilities that you want to access from the search button by tapping the check box.
Swipe down the menu bar to access the Smart Bar’s application utilities that we have configured.
“Task Manager” shows us a list of running applications and the memory that they are using. “Application Manager” is a utility to backup, restore, and uninstall applications. “Show Recent Apps” gives us quick access to the most recent 12 applications that we have been using. “End all tasks but current one” frees up our phone’s memory by killing applications that are dormant.
Folders, Quick Settings, and SmartBar are only some of the great tools that give us quick access to application shortcuts on our Android home screen. Of course there are other ways to manage our application short cuts on the home screen.
