Is other Activities are also have that code? 
I meant, other Activity that doesn't extends BaseActivity?

I would prefer to set in <code>AndroidManifest.xml</code> file in each activity tag like >> <code>android:screenOrientation="portrait"</code>

blocks|key|238477|text|将此行android:screenOrientation="portrait"添加到活动中的项目清单文件中。希望一切顺利。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|238478|entityMap^0|3|10|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

add this line <code>android:screenOrientation="portrait"</code> in your project manifest file inside activity. Hope it work well.

Try this 

<pre><code>&lt;activity

 android:configChanges="orientation|keyboardHidden|screenSize"
 android:label="@string/title_activity_test_edit"
 android:screenOrientation="sensorPortrait"

Portrait orientation, but can be either normal or reverse portrait based on the device sensor.

As you mentioned, 

<blockquote>
 phones have forced portrait mode, while tablets support portrait mode
 as well as landscape mode
</blockquote>

Set screen orientation in <code>manifest</code> will not work.
Use <code>layout-land-sw600dp</code>, <code>layout-land-sw720dp</code> folders for landscape view for tablets. Also please take a look at this <a href="https://stackoverflow.com/questions/9627774/android-allow-portrait-and-landscape-for-tablets-but-force-portrait-on-phone">SO thread</a>

I'm currently developing an app, in which phones have forced portrait mode, while tablets support portrait mode as well as landscape mode. Some pages the layouts have respective landscape versions in the layout-land folder.

The problem

While using the app on a phone (so portrait only) and when autorotate on the phone is enabled, the landscape layout file gets loaded while the app is displayed as portrait mode. 

When does this occur

To recreate this behaviour I open an activity and rotate the device. Then when I navigate to another activity, or close and open the application, the landscape layout gets loaded. 

Method of forcing portrait mode

To force portrait mode on phones, I call

<pre><code>setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
</code></pre>

in my BaseActivity <code>onCreate</code> method.

Other details

targetSdkVersion: 26
using support library 26.0.0

Thank you for helping!

Edit 1:

Unfortunately using (a combination of) the following settings in the manifest file gives the same behaviour.

<ul>
<li><code>android:screenOrientation="sensorPortrait"</code></li>
<li><code>android:screenOrientation="portrait"</code></li>
<li><code>android:configChanges="orientation"</code></li>
</ul>

Edit 2:

I've now tested on multiple devices (emulator, One plus, Motorola, Samsung and some more) and this oddity only happens on a Samsung A5 (api 23) for me.

Landscape layout file is loaded, while portrait mode is forced. (Android)

我目前正在开发一个应用程序，其中手机有强制肖像模式，而平板电脑支持肖像模式以及景观模式。有些页面的布局在布局-土地文件夹中有各自的景观版本。问题当在手机上使用应用程序时(所以只使用肖像)，当手机上的自动登录功能启用时，当应用程序显示为纵向模式时，景观布局文件就会被加载。这发生在什么时候要重新创建这种行为，我打开一个活动...
