I noticed that whwn I build from the cupcake branch, the browser
crashes immediately, because the bad armv5 gears.so is present in
/data/data/com.android.browser/app_plugins/. I don't have this problem
when I install the 1.5 alpha version. Are all the Koolu changes in the
public tree?
In any case, I decided to try to build a good gears.so for Freerunner.
It worked, and I know have GMail and Google Calendar working offline
in the browser!
Here's the procedure I followed:
* Checkout Gears source with SVN:
svn checkout http://gears.googlecode.com/svn/trunk/ gears-read-only
* Change into the gears directory:
cd gears-read-only/
* Update the tree to version or the binary on the cupcake branch, 0.5.17.0
svn -r 3291 update
* Patch config.mk as follows:
Index: gears/tools/config.mk

* Setup the environment
export ANDROID_BUILD_TOP=/home/jim/projects/mydroid-cupcake/
export
ANDROID_TOOLCHAIN=$ANDROID_BUILD_TOP/prebuilt/linux-x86/toolchain/armv4t-android-eabi-4.2.1/bin/
export ANDROID_PRODUCT_OUT=$ANDROID_BUILD_TOP/out/target/product/freerunner/
* Build
cd gears/
make OS=android MODE=opt
* The build creates
gears/gears/bin-opt/installers/gears-android-opt-0.5.17.0.zip I
extracted gears.so from there and used adb to copy it to
/data/data/com.android.browser/app_plugins/ on my FR. After
restarting, the browser doesn't crash, and prompts for permission to
use Gears when I go to sites that use it.
Hope this helps!
Jim
