问题
On Windows 7 64-bit, running Eclipse 3.6 64-bit, JDK (jdk1.6.0_23) 64-bit and Android 2.3 (bitness?), running a program via Eclipse's Run|Run (Ctrl+F11) invokes the android emulator, but won't install .apk on the emulator (and certainly won't run it).
(update, answering @Computerish's question) All I am getting at Eclipse's Console is:
[2010-12-16 10:23:33 - HelloAndroid] ------------------------------
[2010-12-16 10:23:33 - HelloAndroid] Android Launch!
[2010-12-16 10:23:33 - HelloAndroid] adb is running normally.
[2010-12-16 10:23:33 - HelloAndroid] Performing com.example.helloandroid.HelloAndroid activity launch
[2010-12-16 10:23:33 - HelloAndroid] Automatic Target Mode: launching new emulator with compatible AVD 'AVD23'
[2010-12-16 10:23:33 - HelloAndroid] Launching a new emulator with Virtual Device 'AVD23'
This problem doesn't happen on Windows XP, running Eclipse 3.5.2 and Android 2.2 (all 32-bit).
I tried the solution suggested by the accepted answer in this thread but it didn't help. Task manager shows adb's Image Name as 'adb.exe *32'. Perhaps there is a mismatch between the bitness of Eclipse+JDK (64-bit) and the Android emulator/SDK?
Is Android development using 64-bit JDK not possible (yet)?
回答1:
OK, here is the final answer (as of today): Android development, using 64-bit JDK only, is not possible (yet).
If you install the 64-bit Eclipse and install only the 32-bit JDK, Eclipse will refuse to start.
So, if you decided to install the 64-bit Eclipse, you need to install both the 64-bit JDK and the 32-bit JDK.
Thereafter, even the infamous installer_r08-windows.exe will run (and even invoke "SDK Manager.exe" automatically for you).
But 64-bit Eclipse still won't install .apk on Android emulator.
Conclusion: Google is absolutely correct in stating that Android is not supported (yet) under 64-bit Windows. The fact that some geniuses manages to do some magic to make their environment work is beyond me.

I suppose that 32-bit ADB waits for 32-bit JDK. Just install 32-bit JDK - and everything should work after that. i'm running Android SDK on 64 bit machine with both installed JDK's 32 and 64 bits - and everything is OK
回答3:
I know this might be late, but I found a fix for it.
I'm running:
-64-bit Windows 7
-64-bit Java 1.7 SDK
-64-bit Eclipse for Java Developers + ADT Plugin
-64-bit Android SDK
So what I do is save my java source files, and run the application through Eclipse. I close the emulator after it fully loads to the home screen. Next, I go to my command prompt in Win7 and type emulator -verbose -avd youravdname. After you press enter, Eclipse will decide to upload and install the .apk file onto the emulator. Now you can see your new activities!
It's very cumbersome, and I wonder why this even works. I seriously spent hours wondering if I even installed everything correctly.

I had the same problem as the original poster and I'm also using Android SDK 2.3, Eclipse Helios, JDK 1.6.0_23 64-bit on Windows 7 Professional 64-bit.
However, once I've killed the adb.exe *32 process and then restarted eclipse and then tried running HelloAndroid app again, the emulator started successfully, the app *.apk was loaded and ran perfectly.
I didn't do anything else and I haven't installed JDK 32-bit on my machine.
