Camera cannot autofocus and cannot start surfaceView when the activity access in the second time

[hei1682004]

Although I have added:
< uses-feature android:name="android.hardware.camera.autofocus" / >

The camera still cannot autofocus
how to fix it?

camera.getParameters().setFocusMode(android.hardware.Camera.Parameters.FOCUS_MODE_CONTINUOUS_VIDEO);
may have to be set but I do not know how to access the camera instance of libstreaming

Is it possible to control the parameter of camera myself?

---

In onDestory of activity,
super.onDestroy();
mClient.release();
mSession.release();
have been added.
And other coding almost exactly with example 3.

but when I get into this activity again,
the surface view does not show anything.
(I have checked and confirm that the onDestory is run when I get back to the previous activity)
what's wrong?
