Segmentation Fault trying to set battery level in android emulator

Question

I am using Android SDK tools on Ubuntu. I have created a Nexus One Virtual Device that uses API-17. I run this emulator which attaches to port 5554.

After this, I connect to this port using telnet, and try to set power level:

power capacity 40

But, when I do this, I get segmentation and emulator gets killed. Also, when I goto Settings > Battery in emulator, it shows "Battery Status Not Available" and battery is 0%.

All other commands work, except the power related ones. What should I do?

Answer 1

I just had the same problem and luckily found a solution.

1. Go to your Android Virtual Devices folder. On Windows 7 it's this folder for example:

   C:\Users\{yourUserName}\.android\avd\{yourAVDName}.avd

2. Open the config.ini file

3. Set the battery option to yes: hw.battery=yes
4. Restart your Virtual Device and be happy :-)

It has been raised as an issue already, but I'm not sure why they didn't fix it yet.
