Not sure how to best disable all of these tests, so leaving them enabled for now, but PTAL ASAP.

To get the full stack as the error stack trace recommends, do the following:

- Go to https://build.chromium.org/p/chromium.linux/builders/Android%20Tests%20%28dbg%29/builds/45611
- (Optional) Check non-green only
- Open the result_details link in the failing target
- Open link to failing test suite, in this case "org.chromium.chrome.browser.payments.PaymentRequestDynamicShippingSingleAddressTest"
- Open logcat link besides failing test: testSelectValidAddressAndPay
- Scroll up to find actual StrictMode stack trace

Mathieu could you please take a look? This is causing significant flakiness on the Chromium waterfall on the "Android Tests (dbg)" bot. Are these payment tests the cause of the StrictMode violation a more fundamental issue?

Elly: Can you provide us with the "adb logcat" of the failed test run? That's the only place that contains the stack trace that caused the strict mode violation, but I can't find it in the links that you've provided.

Found the logcat here:

https://luci-logdog.appspot.com/v/?s=chromium%2Fandroid%2Fswarming%2Flogcats%2F389d7181692ff011%2F%2B%2Flogcat_org.chromium.chrome.browser.payments.PaymentRequestDynamicShippingSingleAddressTest.testSelectValidAddressAndPay_20170915T082759-UTC_0cbbdb8c0c36f2d4

But it does not contain any payment package symbols...

Looks like violation happens in Android call android.view.Display.getRotation(Display.java:533), which is called from Chromium code org.chromium.ui.display.PhysicalDisplayAndroid.updateFromDisplay(PhysicalDisplayAndroid.java:124). Not sure we can do anything with Android system calls, except suppressing strict mode checks for that particular line of code.

This came up as well in  issue 765936 .

It looks like this is still happening:
https://build.chromium.org/p/tryserver.chromium.android/builders/linux_android_rel_ng/builds/412240
https://build.chromium.org/p/tryserver.chromium.android/builders/linux_android_rel_ng/builds/412258

Maybe you could suppress the strict mode violation if there is no other way to fix this? 
This is done for loading preferences as well (https://cs.chromium.org/chromium/src/chrome/android/java/src/org/chromium/chrome/browser/preferences/PreferenceUtils.java)

 Issue 778234  has been merged into this issue.
