问题
Whenever I call this method in the Android emulator:
SensorManager sensorManager = (SensorManager)getSystemService(Context.SENSOR_SERVICE);
The emulator hangs. When searching for this problem, I find a lot of references of this being fixed back in 2009, but I'm currently using the latest SDK/Tools available at the current time (Dec 2011). API level 8 / v2.2.
Must I really implement code for checking if I run in the emulator and avoid all sensor based code?
回答1:
I experienced something similar with API7 in the emulator: the mentioned code causes the emulator to quit the program immediatly without any warning or log message. (API4 & API10 are ok; I did not test API8 specifically).
I have solved it by setting accelerometer to false in the AVD settings. (I tried this because of issues with the accelerometer in API14/API15 with launch from snapshot.)

I had the same issue with SDK r16 (Dec 2011), turning off accelerometer and magnetic field did not help.
So finally I recreated AVD and turned off 3 things in avd properties: Accelerometer, Magnetic field and Orientation. Now it works good.
