我有点难过。

我已经为我的所有活动添加了多窗口支持intent-filter

  <intent-filter>
     <category android:name="android.intent.category.MULTIWINDOW_LAUNCHER" />
  </intent-filter>

例子：

<activity
    android:name="xx.Rights"
    android:label="@string/title_activity_rights"
    android:parentActivityName="xx.MainActivity"
    android:screenOrientation="portrait"
    android:theme="@style/AppTheme.NoActionBar">
    <intent-filter>
        <category android:name="android.intent.category.MULTIWINDOW_LAUNCHER" />
    </intent-filter>
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value="xx.MainActivity" />
</activity>

我已经添加了库支持

 <uses-library android:required="false" android:name="com.sec.android.app.multiwindow" />
 <meta-data android:name="com.sec.android.support.multiwindow" android:value="true" />

分屏效果很好。我可以在我的 Galaxy S7 上创建半手机分屏以及弹出视图。但是在长时间使用后，多次弹出或分屏 - 我的分屏或弹出功能突然停止。

(ActivityName) does not support split screen view无论我参加什么活动，我都会收到祝酒词。所有活动都经过测试并在某个时候起作用。不知道是什么触发了这个停止。

这是我在成功和失败使用期间的 Logcats。

分屏

12-21 10:58:34.706 11166-11166/xx D/ViewRootImpl: #3 mView = null
12-21 10:58:36.546 11166-11166/xx D/ViewRootImpl: MSG_RESIZED: ci=Rect(0, 0 - 0, 0) vi=Rect(0, 0 - 0, 0) or=1
12-21 10:58:36.546 11166-11166/xx D/ViewRootImpl: MSG_RESIZED: ci=Rect(0, 0 - 0, 0) vi=Rect(0, 0 - 0, 0) or=1

返回全屏

12-21 11:00:51.196 18608-18608/xx D/ViewRootImpl: MSG_RESIZED_REPORT: ci=Rect(0, 96 - 0, 0) vi=Rect(0, 96 - 0, 0) or=1

激活新活动，突然无法在任何地方使用分屏。
