Top 10 Android Tools Apps in February 2015 (playboard.me)

Automatically mount and dismount USB sticks on various devices like the Galaxy Nexus, Nexus 7 and Nexus 10. The Nexus 4 is not supported - this is an issue with the device, not with StickMount !

!!! REQUIRES ROOT !!!

Various Nexus and "stock Android" devices do not automatically "mount" mass storage devices (such as USB sticks). StickMount has been made to solve this problem, and give you access to the files on your USB connected storage from all your apps.

StickMount is known to work on many devices, but is built *only* with *Nexus* devices in mind.

Once StickMount is installed and you connect a USB stick with a "USB host / OTG cable", the device will show you a popup if you want to open StickMount. It is advised to tell the device that you want to do this by default.

If you have just installed StickMount and you already had a USB stick connected, you must manually launch the program, or disconnect/reconnect the USB stick for StickMount to start working.

Mass storage devices are mounted to "/sdcard/usbStorage/xxxx/".

----- (Pro) Kill apps preventing unmount -----

Sometimes an app has a file in use located on the USB device, and won't let go of it. This can prevent StickMount from unmounting the USB device. It will seem like the device stays connected (this is harmless). StickMount Pro provides an option that attempts to kill (terminate) all the apps that are preventing the unmount from succeeding.

----- (Pro) Media scan -----

StickMount Pro supports triggering the media scanner on each (un)mount action. This will automatically make the files on your USB device available in apps like Gallery and Music. Please note that the media scanner is not a visible process on all Android devices - it might actually work silently in the background without any visual cues. It may take a minute for your files to show up, so don't panic if they don't show immediately.

Even if you have this option enabled, you can prevent folders from being scanned by placing an empty file called ".nomedia" in that folder. If you put it in the root of the USB device, the entire device will not be scanned.

----- (Pro) Mount as partition label -----

Instead of using the block device name for the partition, use the partition label as mount name, falling back to uuid or block device name if the label is unavailable.

----- (Pro) Create symbolic links -----

Create symbolic links in /mnt and /storage to the actual mounts in /sdcard/usbStorage/

----- Filesystem support -----

The filesystems supported depends on your device firmware. On most devices, at least vfat/fat/fat32 and ext2/3/4 are supported. On the latest Android versions, ntfs is also supported in read-only mode. Some devices also support exfat out the box, but most do not.

StickMount can utilize the "ntfs-3g" and "mount.exfat-fuse" binaries to add support for ntfs (untested) and exfat, but these are not included. If you place the "ntfs-3g" or "mount.exfat-fuse" files in the root of your internal storage ( /sdcard ), StickMount will automatically use them.

You can find the needed files here:
ntfs-3g: http://forum.xda-developers.com/attachment.php?attachmentid=1145436&stc=1&d=1340293802
mount.exfat-fuse: http://forum.xda-developers.com/attachment.php?attachmentid=806200&d=1323109372

----- Troubleshooting -----

For some users, the app appears not to work, while in fact it is the device itself or the cable not working. One OTG cable is not the other OTG cable. If you have a USB stick with a light on it, it should light up when you connect it to the Galaxy Nexus using your OTG cable. If it does not, either your cable or your Nexus is faulty. 99 out of 100 times it is going to be your cable. That the cable works fine with another device does not mean anything! Cables known to work on a one devices may not work on another device.

SD card unmounting: If your SD card unmounts when unmounting a USB device, you have a bug in your kernel. This is *not* a bug in StickMount !

Shows enumerated usb devices, and allows you to mount external mass storage devices to the filesystem. Supports advanced features like the ability to reload partition tables and reseting USB devices. It can also control the USB Host functionality of S5PC210 devices with the appropriate kernel patch (more about this later)

The application does not use the USB Host API, so it can also run on older, 2.x devices. Because of that however almost all functionality (except for the listing of USB devices) requires root (superuser) access, and a recent version of busybox installed!

The application needs a device that has USB Host (or USB OTG) functionality. Most modern high-end devices have this ability. Check the documentation and specification of your device (this functionality is usually called USB OTG or USB Host)

If your device doesn't have native USB OTG functionality, there are kernel patches for some older devices to enable the functionality, most notably for:

- S5PC210 (Hummingbird) based Samsung phones (Galaxy S, Captivate, Nexus S)
- QSD8250 (Snapdragon) based HTC phones (G1, Nexus One, Desire, Incredible)

You can find appropriate kernel drivers for these phones here:
- Hummingbird / Samsung phones: http://forum.xda-developers.com/showthread.php?t=1450298
- Snapdragon / HTC phones: http://sven.killig.de/android/N1/2.2/usb_host/

Note that these drivers might require skills to install, and may damage your phone and void your warranty!

The app. detects and offers solutions to issues around USB Host and OTG cables. THIS SOFTWARE WILL NOT MOUNT OR SHOW THE FILES ON A USB DRIVE. It verifies your OTG cable is good and that Android can see the USB device. Other software may be required to see the files.

Usage:
1. Disconnect your OTG cable when prompted.
2. Connect your OTG cable when prompted.
3. If everything is OK, you will get 4 green check marks. If nothing happens or you get less than 4 green checks, tap More Info (Web) for a description of the problem.

Software can not overcome a hardware limitation. If your device does not support OTG, nothing will happen when you connect the cable. Please do not write a bad review because your hardware does not support OTG! If your device does support OTG and it is not detected by this software, please contact me via the "Email Developer" link.

Required hardware:
1. An OTG cable
2. A flash/pen drive, card reader or camera.

USB Host Diagnostics determines your device's USB host capabilities.

USB host is a very powerful feature of recent Android based smartphones and tablets, but on many firmwares (both stock and custom) the feature is somewhat broken.

For example, at launch the Galaxy Nexus told all the apps and the Market that it supported USB host, but USB host did not actually work (this was fixed in the Android 4.0.2 update). This broke several apps.

That is just one example of many. There are even cases where OEMs advertise USB host support, but the device does not support it at all. It appears as if USB host support isn't tested by Google or the OEMs when they push out new firmwares and devices at all.

As we cannot depend on Google or the OEMs to correctly provide information regarding USB host support, and the Android framework will regularly lie about it to both the Market as well as Android apps, this application was created so you can test your device's USB host capabilities for yourself.

If you allow it, the app will also submit your results to my website, so together we can create a complete database of devices and firmwares and their USB host support.

This tool may also come in handy for those porting firmwares.

Requirements:
- Android 2.3.1 or newer
- (Optional) Root
- USB OTG cable (unless your device has a fullsize USB port)
- USB memory stick, or another USB device to test the connection with

This app is available EXCLUSIVELY from Play Store to protect Users from malicious app tampering.
A large number of phones/tablets provide basic USB OTG support for mouse and keyboard, but don't provide support for USB Mass Storage devices.

The purpose of this app is to determine if your phone/tablet can provide support for USB Mass Storage devices (e.g. USB Memory Stick) and specifically a connected USB Mass Storage device.

This app checks for the presence of any connected USB Mass Storage device. Screen is updated every couple of seconds, so is Conclusion when any device is connected. Special checks determine the presence of a Mobius ActionCam or #16 camera (with or without SD card inserted).

This tool is a simple tool for Developpers.You can call Settings UI which can toggle Enabling USB Debug etc,same as Settings -> Applications -> Development.You can check your own appearance to select there.(in your environment,item numbers shown may be different from screenshots).I place this tool at my home screen.
I made this tool for practice purpose and my own use.

※This tool is not usb driver.Please install usb driver if you can't connect device and pc.Usually you can download it from device vendor's site.

ps
I got inquiry,so add notes.
At first, I try to make this tool as widget which can toggle USB Debug settings directly if you touch it.But I don't adapt it because it's not recommended way from Android 1.5. So I choose normal Activity which just finishes after calling Settings UI.

Requires root access!! Does not work on KitKat and above for now.

This application allows you to enable USB Mass Storage mode on select Samsung and Sony devices.

This will export your microSD card over USB as a mass storage device, this will NOT work with your internal memory due to hardware and software limitations.

You can also create shortcuts to easily toggle between UMS on and off.

Tested or reported working on:
* Samsung Galaxy S4 (GT-I9500, GT-I9505, SGH-I337, SGH-M919)
* Samsung Galaxy SIII (GT-I9300, GT-I9305, SPH-L710)
* Samsung Galaxy Note II (GT-N7100)
* Samsung Grand Duos (GT-I9082)
Thanks to d4fseeker and Sakaschi for the methods used to enable UMS.

As of version 2.2, there's a new pro version that has auto-switching. If you have donated before, please contact me and I'll arrange a workaround for you as it's unfair for you to pay twice, thank you :)

Flashing with Mobile ODIN does NOT increase your custom kernel flash counter or make the yellow warning triangle appear.

Discussion and support: http://forum.xda-developers.com/showthread.php?t=1347899

MANUAL

Flashing with Mobile ODIN is easy. You start by starting the app and the app will check your system has everything it needs to continue (like root). It may need to download an additional package, so it is advised you have Wi-Fi available.

Now you should see the main Mobile ODIN screen. It will list a set of partitions. Clicking a partition will allow you to select a file from your SD card to flash to that partition. Do not worry about selecting the wrong file - Mobile ODIN will not let you. Separate files (named after the partition) as well as .tar and .tar.md5 files are supported.

From the desktop ODIN you may be used to "PDA", "PHONE", and "CSC" buttons. All three of these buttons have been replaced by the "Open file ..." button. This button will open the file you select from the SD card, and find all the partitions it can flash inside that file. So if you select a .tar file containing kernel and modem, the Kernel and Modem partitions will be set up to use that .tar file for flashing.

Now that we have selected what we want to flash, if you have the Pro version you can proceed to the EverRoot section. The EverRoot options allows you to root your firmware while it is being flashed. Never again will you be without root! Select here which apps you want to inject in the firmware that is being flashed.

Now that we are all done selecting partitions and configuring EverRoot, we continue to "Flash firmware". Mobile ODIN will gather all the information it needs and perform the flash. Before starting, however, it will check that your battery level is over 50%, and if applicable offer to verify MD5 checksums on the files you have selected to flash. If all is well, it will reboot into recovery mode, and flash the firmware you have selected.

This is the official Smart Connect app from Sony. With Smart Connect you can decide what happens when you connect your Android smartphone or tablet to an accessory or other device. It is device and time sensitive. You can choose between single and multiple actions such as starting the music player, a slideshow, turning GPS or Wi-Fi on/off - whatever you want.

Smart Connect also helps you set up and manage smart accessories such as SmartWatch, SmartTags, and app-enabled Bluetooth® headsets from Sony. When you connect your smart accessory, Smart Connect identifies it and downloads any required app for that specific device. It will also find any app extensions available for that accessory.

Previously connected devices are listed within Smart Connect to give you easy access to information and device options.

Note
Smart Connect replaces LiveWare™ manager from Android 4.0

OTG Disk Explorer lets you to read USB flash drives as well as card readers from your Nexus 7 or Nexus 10 tablets. All you have to do is connect the flash drive to an OTG(On-the-go) cable then plug in the micro USB connector of your tablet, then open this app you will see all files in USB drive and you can open them with your favorite app viewers or editors. Current support FAT32 disk format of flash drives.

Note: Before you buy this program, It is strongly suggest that you may install free OTG Disk Explorer Lite and test if your device and flash drive work well,

▌Please do not un-install this app!
You can hide the launcher icon from within the app. You can still access the app from within the options menu of the main app.

▌ FAQ
----------
(1) What is automatic mount? Will it work for me?
The app listens for USB_DEVICE_ATTACHED and BOOT_COMPLETED intents. If your device does not send the intent, automatic mount will not work.
Also, once main app should have been opened manually beforehand for it to work.

(2) What is automatically open file manager?
After mount, the app can automatically open the file explorer..
Only some file managers (eg OI File Manager) support the intent for opening at a specified folder and are recommended.
Other file managers are just launched and are indicated with an asterix (*).

(3) Features are not unlocked / Getting repeated License check Retry?
First time verification will need internet access. The license policy is managed by google (ServerManagedPolicy), so license check may happen maximum once per session in the main app. If you find it annoying, feel free to contact me, I may change it.
