Block android rotation [duplicate]

You should go in the manifest of your project and for each activity you should add the following line

    android:screenOrientation="portrait"

Example

 <activity
            android:name=".MainActivity"
            android:screenOrientation="portrait"
            android:label="@string/title_activity_main" >
        </activity>

Put this in each Activity setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
