I'm having this exact same problem with android 1.5. Specifically,
when I plug in the USB, press the MENU button, and select
"Notifications," the "USB connected" option appears. But when I click
it, nothing happens. I've concluded [as Devin Yu did] that the
UsbStorageActivity is getting launched and creating it's view. But
for some reason, it does not appear on the screen as expected.
Details follow. I hope you can suggest where I should look next.
== DETAILS ==
logcat reports the following as I perform the steps described above
(augmented with some D/B log messages that I added):
W/InputManagerService( 833): Window already focused, ignoring focus
gain of: com.android.internal.view.IInputMethodClient$Stub
$pr...@43694d18
I/ActivityManager( 833): Starting activity: Intent { comp={android/
com.android.internal.app.UsbStorageActivity} }
W/ActivityManager( 833): startActivity called from non-Activity
context; forcing Intent.FLAG_ACTIVITY_NEW_TASK for: Intent
{ flags=0x800000 comp={android/
com.android.internal.app.UsbStorageActivity} }
D/B ( 833): onCreate called.
D/B ( 833): Setting up view.
D/B ( 833): Done Setting up view.
D/B ( 833): onCreate Done.
W/InputManagerService( 833): Window already focused, ignoring focus
gain of: com.android.internal.view.IInputMethodClient$Stub
$pr...@43675e68
I took the InputManagerService warning message as benign because it
happens when any of the main screen context menu apps return.
I tried to launch the UsbStorageActivity using am as Dianne Hackborn
recommends, but it fails. Is there something wrong with my command
line?:
$ adb shell am start -n android/
com.android.internal.app.UsbStorageActivity
Starting: Intent { comp={android/
com.android.internal.app.UsbStorageActivity} }
[1] Killed am start -n andr...
...and logcat says:
