android - Should we expect the app in holo design or material design when using AppCompat -


i have app runs on android 2.3 , above.

recently, i'm in process of migrating sherlockactionbar, appcompat, following guideline what common issues when migrating actionbarsherlock actionbarcompat?

this had done far.

upgrade sdk version

change sdk from

<uses-sdk     android:minsdkversion="10"     android:targetsdkversion="21" />

to 

<uses-sdk     android:minsdkversion="10"     android:targetsdkversion="22" />

theme upgrade

change theme from

theme.sherlock.light.darkactionbar

to

theme.appcompat.light.darkactionbar

code update

following code change guideline what common issues when migrating actionbarsherlock actionbarcompat?.

note, i'm still stick actionbar instead of toolbar. eventually, shall move code toolbar. since migration huge project. rather done bit bit.

my expectation that

  1. app runs on android 2.3 till android 4, should have old school holo design. expect app same, 1 built using sherlockactionbar.
  2. app runs on android 5+, have new material design.

however, here's how app before & after migration, 2.3 app.

before migration

after migration

it seems after migration, can observe that

  1. action bar height higher.
  2. the dialog box ok cancel buttons, had changed 3d material flat.

i wondering, should correct expectation on old app (app runs on 2.3 till 4+), when built against appcompat, latest sdk 22 target? should material app, or holo app?

from support library features section appcompat:

this library adds support action bar user interface design pattern. library includes support material design user interface implementations.

so seeing expected behavior- appcompat designed bring actionbar , material devices api 7 , up.

prior release of version 21 of appcompat alongside android lollipop (api 21), appcompat did indeed provide actionbar holo theming. however, never styled other components, ever actionbar itself.
