Wakelock in android app to keep it alive

Wakelock in android app to keep it alive.

Also make the background black or configurable to save power on oled screens.

My fork GfxTablet+ (see earlier message) has configurable background color, and also inversion of colors. (It does everything GfxTablet does and much more - you have to install networktablet+ instead of networktablet on your Linux desktop computer; the new protocol is incompatible with the one used by GfxTablet, but both apps can be used independently). There is no wakelock at this point, but it would be extremely easy to add that. I'll definitely include a wakelock in the next release.

Thanks. I have tried your fork, it is not for me.

The Android app appears to have everything and the kitchen sink while all I want is a tablet input device.
Then the next detractor was that the xinput driver hung my x session on the first try, and I had to kill it from a different console to regain x, while the original one seems to be very stable so far.

Sorry for that - I have tried it here on different Linux/Debian systems, and
it works very well for me without any drawback; but I haven't made tests on
other Linux variants.

For sure, networktablet+ requires a lot of interaction with X, while
networktablet only interacts through uinput. If you only need a tablet
input device, what you can do is to download the Android SDK, add a
wakelock to GfxTablet, and recompile. Actually, one needs only adding
one line :

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

in the routine from CanvasActivity.java :
protected void onCreate(Bundle savedInstanceState) ...

Best,

An easy "wakelock" solution is to use Tasker with a simple profile that keeps the screen on for "24/hrs", or however long you want to set it for. I have a "screen on" task setup for a handful of apps that I don't want timing out the minute I set the tablet down.
