I've found this code fragment in the newest API 23 SDK's source code
WifiServiceImpl.java Line964
if (!canReadPeerMacAddresses && !isActiveNetworkScorer && !isLocationEnabled()) {
return new ArrayList<ScanResult>();
}
It could explain this issue.The method "isLocationEnabled" read Location settings then returns false at this condition, and getScanResults returns null.

Thank you for your comment.
getScanResults() returns current results on Lollipop and older even if GPS is disabled.
Scan results should have no relation to GPS.

I had confirmed the same with Nexus 5 Preview 3 (build num.: MPA44G).

This is affecting App which need scanned wifi networks but not necessarily want GPS enabled. And by enabling GPS it is gonna drain the battery faster. Which may result in inefficient user experience..
Why location service is mandated now. Is google collecting geo location along with wifi networks for other project?

I also asked this problem on M-preview issue tracker.
On MRA58K, we still have to enable GPS to get ScanResults.

For typical android users, it is may be quite difficult to find relation between Wi-Fi scanning and location settings.
ScanResults should be available if location permission is granted.

Thanks for the suggestion. Our development team has looked into this bug and decided that it is working as per the design.
WifiManager#getScanResults() returns an empty list if location is turned off for the device.

Description
What steps will reproduce the problem?
1. Update Espresso from 2.x to 3.0.0
2. Don't update `com.android.support.test.runner` from 0.5 to 1.0 because it's not working out of the box.
3. Observe that build fails because Espresso 3.0.0 can not be used with Test Runner 0.5 (unless you start hacking build process to force that)
How are you running your tests (via Android Studio, Gradle, adb, etc.)?
./gradlew connectedAndroidTest, Composer (
What is the expected output? What do you see instead?
Espresso should NOT depend on test runner. It's just a UI test library. It should not matter what test runner you use with Espresso.
It's like if AsserJ would depend on JUnit.
