Just a short update:
I have created a branch called gsoc-janschejbal, where I will be
putting all my changes. To get familiar with the project, I implemented
ActionBar support and committed it to the branch. Any feedback is
welcome, of course.
To ensure compatibility with old devices, I used the ActionBarSherlock
library (http://actionbarsherlock.com/), which is licensed under the
same license as Vespucci. I also added some icons from the official
Action Bar Icon Pack by Google, which specifically mentions that it
may be freely used.
To optimally utilize the limited space on the action bar, I decided to
remove the application icon and name. The editing mode is now selectable
trough a dropdown (Dropdown navigation), the four remaining menu items
are added as actions (submenus stay submenus).
The commit also contains two unrelated changes: I bumped MAX_ZOOM_WIDTH
again to allow users to easily move between cities and countries, and I
added some horrible proof-of-concept code for on-device rendering (which
requires the mapsforge library). It really just shows that it is
possible, but is done in the most hack-ish way I came up with.
I located the cause for the high CPU usage while the app is idle:
Updating the compass arrow (which happens quite often) invalidates the
entire map (see the sensorListener in Main.java). I'm probably not going
to do anything about this, at least not until I am done with my actual task.
Kind regards,
Jan
