facebook + android : Only fullscreen opaque activities can request orientation

问题

Facebook SDK version 4.27.0

Android OS version 8.0

App crashes with exception, this is the trace log I have found over Crashlytics:

Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.xxx.yyy/com.facebook.FacebookActivity}: java.lang.IllegalStateException: Only fullscreen opaque activities can request orientation

Can anyone help me with this ?

PS: In Android Source, after looking at this line number 987, it seems that this line is the culprit.

Also, in my manifest:

<activity
    android:name="com.facebook.FacebookActivity"
    android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
    android:label="@string/app_name"
    android:screenOrientation="portrait" />

回答1:

Removing this attribute:

android:screenOrientation="portrait"

from FacebookActivity tag, may solve the problem.

回答2:

When i removed this <item name="android:windowIsTranslucent">true</item> from style problem was solved.

回答3:

From the latest fb integration guide, we don't need to specify either theme or orientation that is causing crash on android 8.0 . So we should use latest fb sdk with their new settings:

<activity android:name="com.facebook.FacebookActivity"
    android:configChanges=
            "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
    android:label="@string/app_name" />

回答4:

remove this line from your style menu

  <item name="android:windowIsTranslucent">true</item>

回答5:

Changed

<style name="AppTheme" parent="android:Theme.Translucent.NoTitleBar"></style>`

to

 <style name="AppTheme" parent="android:Theme.Holo.NoActionBar.TranslucentDecor"></style>

then remove

<item name="android:windowIsTranslucent">true</item>
