Hi everybody,
I implemented a camera preview SurfaceView that is loosely based on
the camera preview example from the android apis demo.
On the same activity, i have some live sensor readings displayed.
I always had the idea that the activity is running very slow and i
previously got some image freezings when I switched between two
different activities that both displayed the camera preview. That was
when I was building for SDK 1.1 today I migrated my application to 1.5
and catched the following error message:
06-15 23:56:26.272: ERROR/AndroidRuntime(726):
java.lang.RuntimeException: Out of memory
06-15 23:56:26.272: ERROR/AndroidRuntime(726): at
android.hardware.Camera.native_setup(Native Method)
06-15 23:56:26.272: ERROR/AndroidRuntime(726): at
android.hardware.Camera.<init>(Camera.java:82)
06-15 23:56:26.272: ERROR/AndroidRuntime(726): at
android.hardware.Camera.open(Camera.java:64)
For clarity, I will post the code of my Preview class at the end.
Any idea what could be wrong?
Thanks a lot for your replies.
