Java.lang.UnsupportedOperationException: For security reasons, WebView is not allowed in privileged processes

[luisflaviovz]

Hi,

Why am I getting this error when rendering my layout?

Rendering Problems
The following classes could not be instantiated:

• com.mopub.mobileads.MoPubView (Open Class, Show Exception, Clear Cache)

Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE

Hello Luisflaviovz,

Have you declared the following permissions and activities in your Android Manifest per the “Getting Started” documentation here?

This error seems to be the result of the web view not having the appropriate permissions.

If using the Base Bundle, please declare the following permissions in your AndroidManifest.xml file.

  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Please declare the following activities:

  <activity android:name="com.mopub.mobileads.MoPubActivity" android:configChanges="keyboardHidden|orientation|screenSize"/>
  <activity android:name="com.mopub.mobileads.MraidActivity" android:configChanges="keyboardHidden|orientation|screenSize"/>
  <activity android:name="com.mopub.common.MoPubBrowser" android:configChanges="keyboardHidden|orientation|screenSize"/>
  <activity android:name="com.mopub.mobileads.MraidVideoPlayerActivity" android:configChanges="keyboardHidden|orientation|screenSize"/>

If using the Full Bundle, please declare the following permissions in your AndroidManifest.xml file.

  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Please declare the following activities:

  <activity android:name="com.mopub.mobileads.MoPubActivity" android:configChanges="keyboardHidden|orientation|screenSize"/>
  <activity android:name="com.mopub.mobileads.MraidActivity" android:configChanges="keyboardHidden|orientation|screenSize"/>
  <activity android:name="com.mopub.common.MoPubBrowser" android:configChanges="keyboardHidden|orientation|screenSize"/>
  <activity android:name="com.mopub.mobileads.MraidVideoPlayerActivity" android:configChanges="keyboardHidden|orientation|screenSize"/>
  <activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />
  <activity android:name="com.millennialmedia.android.MMActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:configChanges="keyboardHidden|orientation|keyboard" />

Let us know if this resolves your issue. If not, we can troubleshoot further.

Thanks!

I encountered the same problem and I am sure I have added the permissions and the activities in the xmls.
