Emulator doesn't work after msg-"sad result from adb&qu

Hi everyone,

When i use the Google APIs Google Inc. sdk 1.6, i generally, got the error in the console of eclipse. Actually, after running the emulator some time and even after 1 or 2 hours, i generally got the msg "sad result from adb" and after that emulator won't work and than i am not able to run any application onto the emulator.

Have anybody any idea regarding this issue?

I am waiting for your suggestions.

Thanks.

Regards,

If I could get Eclipse and the emulator to speak nicely to each other for a whole 2 hours without restarting them, I would be a happier coder

Sorry, to be more clear, a web search reveals "sad result from adb" seems to be thrown by an IOException in Android Project source according to this very long web page on android.git.kernel.org

AdbHelper seems to do with ADB & DDMS, the Dalvik Debug Monitor Server.

Android ships with a debugging tool called the Dalvik Debug Monitor Server (DDMS), which provides port-forwarding services, screen capture on the device, thread and heap information on the device, logcat, process, and radio state information... DDMS acts as a middleman to connect the IDE to the applications running on the device. On Android, every application runs in its own process, each of which hosts its own virtual machine (VM). And each process listens for a debugger on a different port.

Whenever I've seen that error (rarely, in my case) ddms/the emulator does not seem able to recover from it, and it's unclear if it was caused by exceptions in my code, cos when I restart everything the code seems to run fine.

What I was trying to get at in my previous post was, the whole system is wobbly anyway -- Eclipse is not fast in the first place, and over the course of 1-2 hours gradually reduces the UI to a crawl, and then I have to quit it & the emulator. Sometimes on first run it just seems unable to connect to emulator, and I have to restart it. There's loads of little issues.

Like my friends who use Eclipse for non-droid work, on OS X and Windows, I just live with restarting the whole lot every 1-2 hours.

Sorry, I don't have any helpful hints Pranav
