    <activity         android:name=".splashactivity"         android:label="@string/title_activity_splash"         android:screenorientation="portrait">         <intent-filter>             <action android:name="android.intent.action.main" />              <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>

but keep phones , tablet. if way of course layout won't on 7 , 10 inch screens.

question

how set such app run in portrait mode in mobile phones , landscape mode on 7 , 10 inch screens.

thanks in advance.

create new file named bools.xml in values folder below:

<?xml version="1.0" encoding="utf-8"?>     <resources>     <item type="bool" name="islargelayout">false</item> </resources>

create file in values-large folder named bools.xml below: 

<?xml version="1.0" encoding="utf-8"?>     <resources>     <item type="bool" name="islargelayout">true</item> </resources>

now in activity before calling setcontentview resource , based on value decide port or land orientation:

boolean islargelayout = getresources().getboolean(r.bool.islargelayout); if(islargelayout) {     // tablet mode     setrequestedorientation(activityinfo.screen_orientation_landscape); } else {     // handset mode     setrequestedorientation(activityinfo.screen_orientation_portrait); }
