Since not every engine respects pauseEngine(), or they're in a state
where it simply gets ignored, put all threads in a group coma. Without
this, code still kept looping and wasting cpu cycles, while the user
might want to do use her/his droid for something else.
Don't just kill the whole process when the Activity is stopped. Instead,
use its events to pause or resume audio and the running engine (if any).
Of course not every engines implements that... but at least an incoming
call doesn't kill the game now (lol).
- make the startup sequence more linear
- use SurfaceHolder events
- get rid of the surface lock
- remove unnecessary JNI calls
- make the ScummVM class implement Runnable
- cleanup
Most games register a music channel, and when there is no music,
they still stream silence (and run through all the Converter::flow
code!). Scan the buffer for that to pause the AudioTrack. Ugly, but
worth it - reduces CPU usage on many games and hence saves battery life.
Only works in situations without any registered channels (or all paused)
at the mixer (like on the launcher or GMM).
CPU usage before (Galaxy Tab):
~5% scummvm
~15% mediaserver
After:
~2% scummvm
0% mediaserver
;)
This was probably set to ensure onCreateInputConnection() gets called,
but it is regardless of this flag. Now the soft keyboard doesn't show
up on startup on devices without physical keyboard, which prevents
unnecessary surface changes.
- EVENT_SCREEN_CHANGED must happen _after_ we have a new surface,
not when the the old surface vanishes. fixes port on galaxy tab
- textures have to be redefined with glTexImage2D() to make
glTexSubImage2D() not fail on screen changes
- move all android specific make stuff from module.mk to android.mk
- don't create automatically generated files in the source tree
- don't fail when building outside of the source tree
- clean android build files on "make clean"
- cleanup
