Android Studio GridLayout Compatibility for older Androids -


i'm getting error when trying emulate app on 2.3 avd:

    03-10 01:06:56.500      407-407/com.ak.ak0 e/androidruntime﹕ fatal exception: main java.lang.runtimeexception: unable start activity componentinfo{com.ak.ak0/com.ak.ak0.mainactivity}: android.view.inflateexception: binary xml file line #21: error inflating class gridlayout         @ android.app.activitythread.performlaunchactivity(activitythread.java:1647)         @ android.app.activitythread.handlelaunchactivity(activitythread.java:1663)         @ android.app.activitythread.access$1500(activitythread.java:117)         @ android.app.activitythread$h.handlemessage(activitythread.java:931)         @ android.os.handler.dispatchmessage(handler.java:99)         @ android.os.looper.loop(looper.java:123)         @ android.app.activitythread.main(activitythread.java:3683)         @ java.lang.reflect.method.invokenative(native method)         @ java.lang.reflect.method.invoke(method.java:507)         @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:839)         @ com.android.internal.os.zygoteinit.main(zygoteinit.java:597)         @ dalvik.system.nativestart.main(native method)  caused by: android.view.inflateexception: binary xml file line #21: error inflating class gridlayout         @ ................

thing is, unless i'm not understanding gradle file correctly, i'm using android support libraries compatibility:

apply plugin: 'android'  android { compilesdkversion 19 buildtoolsversion "19.0.3"  defaultconfig {     minsdkversion 9     targetsdkversion 19     versioncode 2     versionname "1.0.1"  }  signingconfigs {     release {         storefile file("//")         storepassword "//"         keyalias "//"         keypassword "//"     } }  buildtypes {     release {         runproguard true         proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.txt'          signingconfig signingconfigs.release     } } }  dependencies { compile 'com.android.support:gridlayout-v7:19.0.1' compile 'com.android.support:appcompat-v7:19.0.1' compile filetree(dir: 'libs', include: ['*.jar']) }

the dependencies part build.gradle file automatically generated, i'm expecting them used (although not have concrete knowledge of functionality). question is, what's missing that's causing problem ?

ok running android studio: although adds dependency libraries itself, things not added automatically. following needs added @ beginning of xml file including gridlayout:

xmlns:grid="http://schemas.android.com/apk/res-auto"

apart this, gridlayout tags xml file must replaced android.support.v7.widget.gridlayout

if, me, found out afterwards space needs modifications compatibility, space tags need replaced android.support.v7.widget.space

i know integration tests preferred need ran in controller test, i'm testing gem injecting html code in view, xhr can't run in feature spec (if can, please explain me how :) ) so rspec controller tests can assert selector present (with capybara) : response.body.should have_selector('#foobar') has_selector? call all method capybara find selector. what want last child of body , assert id in particular. afaik it's not possible have_selector. what : all('body:first-child').first.id.should == '#foobar' however, capybara dsl, defined (more or less): def all(*args) page.all(*args) end and page empty unless use visit it's integrations specs. how can use capybara all method inside rspec controller test ? i can't test right after googling seems trick def page capybara::node::simple.new(response.body) end source
