问题
I'm using Windows 7 Ultimate 64 bit edition and Eclipse 3.5 with the Android plugin. Every time I create a new project and try to publish it, I get an error like this:
[2010-02-15 22:48:10 - EPG3]Uploading EPG3.apk onto device 'emulator-5554' [2010-02-15 22:48:15 - EPG3]Failed to upload EPG3.apk on device 'emulator-5554' [2010-02-15 22:48:15 - EPG3]java.io.IOException: Unable to upload file: timeout [2010-02-15 22:48:15 - EPG3]Launch canceled!
The emulator is working perfectly, adb can see it, I can even logcat from it, but it can't push or pull anything from it. Nothing appears in logcat to suggest the emulator even received any command. It doesn't matter if I have the Firewall on or off, or if I try invoking adb install to bypass the plugin. Nothing works even with a blank app.
Any ideas?
回答1:
Not sure if this helps but I had the same exception when I tried uploading a project to the device and fixed it by increasing the value of "adb connection time out (ms)"
PC: (eclipse -> window -> settings -> android -> ddms) MAC: (eclipse -> preferences -> android -> ddms)
I was pretty pissed at myself that it took me so long to find the setting so I thought I'd share.
回答2:
I just ran into this error. To resolve it, I deleted my .apk file and built the project again. Voila! Upload works now.
回答3:
Isnt this a problem with resources loading? Tried all the hello examples without problems, now the first with drawables and now I/O problem as you had.
I think its the reason that in the example they speak of a drawable folder, but in my default project structur there are 3 drawable folders.
Keep on debugging ;)

I got this error about every 30-40 compilations. I don't how, but this solution work for me.
Go to bin/ folder and rename your EPG3-debug.apk file to EPG3.apk (if you are using debug mode) or EPG3-release.apk to EPG3.apk (in Run mode), return to Eclipse, now you can Debug/Run your application. This should "unchoke" this whole situation, so you can make changes in your code and next time Debug/Run program normally (until you get this error once again, then you must repeat this tip).
回答5:
See this question — Windows 7 and Android don't seem to get on so well initially it seems: Failed to parse the output of 'adb version'?
Are you able to telnet to localhost 5037? That's where the adb server listens for incoming connections from adb clients.

Did you try to add the path of the tools directory to your system PATH as described here ?
