I'm trying to stream a video to a custom TextureView. The Video is shown in fullscreen mode. The layout is the same for portrait mode and landscape mode:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/root_layout"
    tools:context=".SampleActivity">
    <com.my.package.MyCustomTextureView
        android:id="@+id/texture_custom"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:keepScreenOn="true" />
    ...
</RelativeLayout>
The Activity in the Manifest is set to handle the orientation changes itself:
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".SampleActivity"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:label="@string/app_name"
        android:theme="@style/FullscreenTheme" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
When the orientation changes, the Activity seems to find the correct size:
public class SampleActivity extends FragmentActivity {
    ....
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        RelativeLayout root = (RelativeLayout) findViewById(R.id.root_layout);
        MyCustomTextureView view = (MyCustomTextureView) findViewById(R.id.texture_custom);
        Log.d(TAG, "onConfigurationChanged newConfig: " + newConfig.screenWidthDp + "x" + newConfig.screenHeightDp + " root: "+root.getWidth() + "x" + root.getHeight() + " view: " + view.getWidth() + "x" + view.getHeight());
        ....
    }
}
Activity log output, when I pass from portrait to landscape (note: this is before the layout change):
09-29 15:30:28.975  22303-22303/com.my.package D/com.my.package.SampleActivity onConfigurationChanged newConfig: 598x335 root: 1080x1920 view: 1080x1920
...but the Custom Texture View is receiving the wrong values:
public class MyCustomTextureView extends TextureView implements TextureView.SurfaceTextureListener {
    ....
    @Override
    public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int width, int height) {
        Log.v(TAG, "onSurfaceTextureSizeChanged params: " + width + "x" + height + ", old values " + mMyWidth + "x" + mMyHeight + ", method values: " + getWidth() + "x" + getHeight());
    }
    ....
}
TextureView log output, when I pass from portrait to landscape:
09-29 15:30:29.037  22303-22303/com.my.package V/com.my.package.MyCustomTextureView﹕ onSurfaceTextureSizeChanged params: 1080x1080, old values 1080x1920, method values: 1080x1080
If I go back to portrait mode, it seems to retrieve the correct size once again:
Activity:
09-29 15:30:45.019  22303-22303/com.my.package D/com.my.package.SampleActivity onConfigurationChanged newConfig: 360x567 layout: 1920x1080 view: 1080x1080
TextureView:
09-29 15:30:45.096  22303-22303/com.my.package V/com.my.package.MyCustomTextureView onSurfaceTextureSizeChanged params: 1080x1920, old values 1080x1920, method values: 1080x1920
What am I doing wrong?
