Tests
are
big

• A
layer
on
the
top
of
instrumenta=on
tests
• A
set
of
hamcrest

Sophis#cated
modularity
for
Android
• Android
does
not
support
reusing
components
from
another
applica=on
• Package
conflict
• Resources
not
found
in
R
• Libraries
do
share
the
same
package
• Rindirect
removes
those
limita=ons
by
genera=ng
the
missing/
required
R
files
• Automated
during
your
build
process
• Allow
advanced
modularity
• Improve
component
sharing

25. Roboject
A
CDI
for
Android
• Android
code
can
be
really
=resome
• A
lot
of
asynchronocity
• Service
bindings,
intents…
• Predominance
of
the
main
thread
• UI
code
can
be
smaller
• Retrieving
a
View,
Senng
a
Layout
• Roboject
dras=cally
simplifies
Android
code
• @InjectX
where
X
is
Service,
Intent,
Extra,
View,
Layout…
• Addi=onal
lifecycle
method
:
onReady
• Reduce
the
amount
of
code
required
to
develop
Android
applica#ons
• Minimum
run#me
overhead
• Extensible
