Disable portrait mode on Android

Question

I want my app to run only on landscape orientation, so I have added android:screenOrientation="landscape"in every activity in the manifest.

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

com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1084)
dalvik.system.NativeStart.main (NativeStart.java)

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.

does activity_layout exist? There could be an error within activity layout. the error means there is an issue with a resource (hence the R). — letsCode, Jul 02 '18 at 15:11
hmm I don't think this will fix the problem, cuz it's working perfectly with me, but in the Crashlytics this is the crash I found, and it occurred many times, and when I dig deeper to see the crash data, I found it occurs when the app in portrait mode, so I'm wondering how it comes in portrait mode in the first place. — Ran, Jul 02 '18 at 15:14

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.

    <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 – Ran Jul 02 '18 at 14:46
check the updated question, maybe I didn't explain it well the previous time – Ran Jul 02 '18 at 14:52
no..u didnt explain any of this before... like... at all. – letsCode Jul 02 '18 at 14:53
my mistake, maybe I didn't know how to explain, do you have any idea on that ? – Ran Jul 02 '18 at 14:54
post your entire crash – letsCode Jul 02 '18 at 14:56
@DrioDev this is the entire crash – Ran Jul 02 '18 at 14:59

You can also change orientation on runtime with setRequestedOrientation(android.content.pm.ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); but you should call before setContentView

it's set to landscape and working correctly with me, but I'm getting many crashes. I don't know why ! – Ran Jul 02 '18 at 15:06
It's quite strange indeed. If set in AndroidManifest.xml it should not change even if user rotates his/her device – Thracian Jul 02 '18 at 15:24
