USB Accessory API on Samsung Galaxy S2 Android

Question

I am not able to launch my android application on to the Samsung Galaxy S2. I am trying to use the Google Add on Library for USB Accessory. When I launch the same application on Google Nexsus S it works fine.

In the application manifest file I have used the following tag (under the application tag):

<uses-library android:name="com.android.future.usb.accessory"/>

The error that i am getting on the console is

[2011-08-11 12:00:28 - App] Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY
[2011-08-11 12:00:28 - App] Please check logcat output for more details.
[2011-08-11 12:00:29 - App] Launch canceled!

Now if I omit the following line from manifest:

<uses-library android:name="com.android.future.usb.accessory"/>

I get the following error on LogCat:

08-11 11:58:40.250: ERROR/AndroidRuntime(30780): java.lang.NoClassDefFoundError: com.android.future.usb.UsbManager

Any ideas to get round this problem?

My goal is to use the USB host (or at least use the USB Accessory API) on Galaxy S2.

I got solution to this problem.

We just need to push one xml file into the device's "/etc/permissions" folder.

android.hardware.usb.accessory.xml with the content

<?xml version="1.0" encoding="utf-8"?>
<permissions>
    <feature name="android.hardware.usb.accessory" />
    <library name="com.android.future.usb.accessory"
           file="/system/framework/com.android.future.usb.accessory.jar" />
</permissions>

If you are getting the "read only file system" error. then you need to root your device like this.

After all reboot. It will work fine.

I have my Samsung Galaxy S II and I can run the applications there without any problems.

You mean to run your applications in "debugg-mode" from the Eclipse? Or you mean to create the .apk and after to install it on your phone?

If it is to run it directly from your Eclipse to your phone, you have to know that first of all, it is neccesary to have the Samsung Drivers installed on the computer, I recommend you to install Samsung kies. Download Samsung Kies

After you install the drivers and so on, remember you have to click on "debug mode" on your phone. It is on "preferences->Applications->development->Usb Debugging

The Problem is with the shared library missing on the phone..! — Noby, Jan 23 '12 at 12:55

I have Samsung Galexy SII. I am facing the same problem before couple of days. Not can able to run my Android Apps in to SII and it works fine. There are no any issue like required shared library or anything else.

Sollution of that Issue:

I just have install the Samsung Kies from here.

Then restart both, Device and PC. and then turn on the USB debugging in to device.

Now connect your Mobile with the PC and then try.

It will surly works.

Enjoy. :)

My OS is Ubuntu 10, Kies for it are not available. – Noby Jan 24 '12 at 10:26
Ohh. . . Let me for your OS. – Shreyash Mahajan Jan 24 '12 at 10:27
@Noby: Sorry budy as i got is, Ubuntu not support Samsung kies. So you should have to try your app in windows/Mac. :( – Shreyash Mahajan Jan 24 '12 at 10:41
@Noby:I suppose you could try running the Windows version in Wine, but I'm not sure if that would be successful. It would require a bit of tinkering most likely to get it working. – Shreyash Mahajan Jan 25 '12 at 10:58
