Google pre-launch stability errors for: com.google.android.apps.mtaas.deviceadmin

I'm trying to submit an update to an existing app to production, but I seem to be failing in the prelaunch for one specific device on on android sdk 26. I can reproduce this on emulation of sdk 26. The testing video seemed to just show the automated testing opening and closing the app and clicking around for about 5 minutes. I didn't seem to see any errors in the app itself.
I'm received several errors and all seem to be related to items related to com.google.android.apps.mtaas .
My app doesn't use any DeviceAdmin features so I'm not sure where these are coming from. Also, after looking at the full logcat file none of these process ID's match with the process ID's of my running app, and some of these seem to occur in the logs before I see much activity from the testing opening/closing my app.
Does anyone have any clue where to begin? I can't seem to recreate it, and without any hint to how they might relate to my code(if they do at all) I can't properly attempt to implement any fix.
I've seen numerous threads about false positives related to the prelaunch reports generating false positivies, but I'm not sure if that's the case here or not.

In XML file you are using different recyclerview and java you are casting different recyclerview that's why the error is coming. Use the same type of recyclerview in both XML and java file.

here is the error log of Interstital ad when open app it will directall crash, i currently test add in the api Level 26, The error like Only fullscreen activities can request orientation , idont know why this is happening.
is there any soluthion for this ? then help me.

EDIT
the newer (above 16) admob version fixed the issue
Old Answer
add this in your manifest
<activity
android:name="com.google.android.gms.ads.AdActivity"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
tools:replace="android:theme"
/>

just simply add this line in your gradle file
targetSdkVersion = 26

If your target SDk version >= 27 then you get this error so try to add below code
void setRequestedOrientation(int requestedOrientation) {
if (ActivityInfo.isFixedOrientation(requestedOrientation) && !fullscreen
&& appInfo.targetSdkVersion > O) {
throw new IllegalStateException("Only fullscreen activities can request orientation");
....
}
