Disable portrait mode on Android
I want my app to run only on landscape orientation, so I have added android:screenOrientation="landscape"in every activity in the manifest.
android:screenOrientation="landscape"
But surprisingly I'm getting so many crashes in Crashlytics and it's showing in the data that the crash occurs while the device is in a portrait mode (how come it's on a prorate mode).
the crash says

and this is my onCreate method
@Override
protected void onCreate(Bundle savedInstanceState) {
setTheme(((AppTheme)getApplicationContext()).getCurrentTheme());
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_layout);
ButterKnife.bind(this);
presenter = new Presenter(this);
setupPages();
enterImmersiveMode();
}
I'm wondering how it's recorded on Crashlytics that the crash occurs when the device is on portrait mode . so I guess that when it's on portrait mode it can't get the layout cuz all the layout in (layout-land) not in the layout folder.
post the entire crash

I don't want to encourage laziness. Here is the answer.
However, please use Google next time. This is some basic information you can find easily.
Add android:screenOrientation="landscape" to the activity in the manifest.
android:screenOrientation="landscape"
<activity android:name=".MainActivity"
android:screenOrientation="landscape">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
it's not laziness this is what I'm doing. But after publishing my app, I opened Crashlytics and there is so many crashes that occurs when the app is portrait

You can also change orientation on runtime with setRequestedOrientation(android.content.pm.ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); but you should call before setContentView
setRequestedOrientation(android.content.pm.ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setContentView
it's set to landscape and working correctly with me, but I'm getting many crashes. I don't know why !

It's quite strange indeed. If set in AndroidManifest.xml it should not change even if user rotates his/her device
