I have just build and installed NRD90U on Nexus 6P. Now I am trying to run the CTS. I have downloaded the Android 7.0 R4 Compatibility Test Suite (CTS) - ARM and copied the media files to the device.

For CTS 7.0 I have installed (adb install -r android-cts/testcases/CtsAdminApp.apk) this as helper and configured android.deviceadmin.cts.CtsDeviceAdminReceiver* under: "Settings >

Security > Select device administrators".

When I am trying to run CTS (run cts --plan ) I am getting

this error:

"E/TestInvocation: Caught exception while running invocation

"E/TestInvocation: Not all target preparation steps completed"

android.tradefed.targetprep.TargerSetupError:Not all Target

Preparation steps completed.

com.android.complatibility.common.tradefed.targetprep.APKInstrumentPreparer.run

(APKInstrumentPreparer.java)

com.android.complatibility.common.tradefed.targetprep.DeviceInfoCollector.setup(DeviceInfoCollector.java)

com.android.tradefed.invoker.TestInvocation.com.android.(TestInvocation.java)

. . . :Invocation failed:

com.android.tradefed.targetprep.TargetSetupError:Not all target

preparation steps completed"

Can anybody please help me to solve it.
