android - how to use Instrumentation under the uiautomator project? -


i'm working on uiautomator project , uiobject.getfromparent turn out wrong element me , source code of uiautomator , found out answer because uiselector used.

i found uiautomator using instrumentation ui element stuff :

getinstrumentation().getuiautomation().getrootinactivewindow();

i want accessibilitynodeinfo node uiautomator uiautomator didn't exposed this.

i’m trying way new class extends instrumentationtestcase,by getinstrumentation() return null me.

i found answer on android instrumentation test case - getinstrumentation() returning null needs injectinstrumentation(instrumentationregistry.getinstrumentation()); , told instrumentationregistry official android testing-support-lib:0.1

i have download android support repository , import testing-support-lib-0.1-source.jar project still can't see instrumentationregistry.

anyone have idea cast?

i'm using extension of instrumentationtestcase , works fine this:

@override public void setup() throws exception{     super.setup();     instrumentation instrumentation = instrumentationregistry.getinstrumentation();     accessibilitynodeinfo root = instrumentation.getuiautomation().getrootinactivewindow(); }

i imported

import android.test.instrumentationtestcase; import android.support.test.instrumentationregistry; import android.view.accessibility.accessibilitynodeinfo;

and installed

android support repository (15) android support library (22.2)

hope helps.
