eclipse - NAND error in Hello World project in the official Android developer tutorial

Question

I'm working on the Hello World project at http://developer.android.com/resources/tutorials/hello-world.html

The trouble comes when I run the application. The sequence of messages I get is something like:

[2012-04-30 15:13:19 - HelloAndroid] ------------------------------
[2012-04-30 15:13:19 - HelloAndroid] Android Launch!
[2012-04-30 15:13:19 - HelloAndroid] adb is running normally.
[2012-04-30 15:13:19 - HelloAndroid] Performing com.example.helloandroid.HelloAndroid activity launch
[2012-04-30 15:13:19 - HelloAndroid] Automatic Target Mode: launching new emulator with compatible AVD 'my_avd'
[2012-04-30 15:13:19 - HelloAndroid] Launching a new emulator with Virtual Device 'my_avd'
[2012-04-30 15:13:25 - Emulator] NAND: could not write file /tmp/android-jhsu/emulator-7iTL7m, File exists

What exactly is stopping the process from executing properly? What do I need to do to fix this?

UPDATE 1:

OK, I tried your suggestions about clearing the avd.

I went into my android_sdk_linux directory and entered "tools/android list avd". The output was:

Available Android Virtual Devices:
Name: my_avd
Path: /home/jhsu/.android/avd/my_avd.avd
Target: Android 4.0.3 (API level 15)
ABI: armeabi-v7a
Skin: WVGA800

So I entered "tools/emulator -avd my_avd -wipe-data". The output was:

NAND: could not write file /tmp/android-jhsu/emulator-5FHEn7, File exists

But I looked in the /tmp/android-jhsu directory and saw no file at all, not even a hidden file.

Where do I go from here?

Answer 1

I was able to fix it exporting ANDROID_TMP

export ANDROID_TMP=/home/myuser
