java.lang.IllegalStateException: Only fullscreen opaque activities can request orientation

The problem seems to be happening when your target sdk is 28. So after trying out many options finally this worked.

<activity
            android:name=".activities.FilterActivity"
            android:theme="@style/Transparent"
            android:windowSoftInputMode="stateHidden|adjustResize" />

style:-

<style name="Transparent" parent="Theme.AppCompat.Light.NoActionBar">
     <item name="android:windowIsTranslucent">true</item>
     <item name="android:windowBackground">@android:color/transparent</item>
     <item name="android:windowIsFloating">true</item>
     <item name="android:windowContentOverlay">@null</item>
     <item name="android:windowNoTitle">true</item>
     <item name="android:backgroundDimEnabled">false</item>
 </style>

Note:parent="Theme.AppCompat.Light.NoActionBar" is needed for api 28. Previously had something else at api 26. Was working great but started to give problem at 28. Hope it helps someone out here. EDIT: For some only by setting <item name="android:windowIsTranslucent">false</item> and <item name="android:windowIsFloating">false</item> worked.May be depends upon the way you implement the solution works.In my case it worked by setting them to true.

In Android O and later this error happens when you set

 android:screenOrientation="portrait"

in Manifest.

Remove that line and use

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

in your activity.

This will fix your issue.

In android Oreo (API 26) you can not change orientation for Activity that have below line in style

 <item name="android:windowIsTranslucent">true</item>

You have two way for solving this :

1) You can simply remove above line (or turn it to false) and your app works fine.

2) Or you can first remove below line from manifest for that activity

android:screenOrientation="portrait"

Then you must add this line to java file

    //android O fix bug orientation
    if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }

Google throws this exception on Activity's onCreate method after v27, their meaning is : if an Activity is translucent or floating, its orientation should be relied on parent(background) Activity, can't make decision on itself.

Even if you remove android:screenOrientation="portrait" from the floating or translucent Activity but fix orientation on its parent(background) Activity, it is still fixed by the parent, I have tested already.

One special situation : if you make translucent on a launcher Activity, it has't parent(background), so always rotate with device. Want to fix it, you have to take another way to replace <item name="android:windowIsTranslucent">true</item> style.

If you use a fullscreen transparent activity, there is no need to specify the orientation lock on the activity. It will take the configuration settings of the parent activity. So if the parent activity has in the manifest:

android:screenOrientation="portrait"

your translucent activity will have the same orientation lock: portrait.

The only solution that really works :

Change:

<item name="android:windowIsTranslucent">true</item>

to:

<item name="android:windowIsTranslucent">false</item>

in styles.xml

But this might induce a problem with your splashscreen (white screen at startup)... In this case, add the following line to your styles.xml:

 <item name="android:windowDisablePreview">true</item> 

just below the windowIsTranslucent line.

Last chance if the previous tips do not work : target SDK 26 instead o 27.

I used android:screenOrientation="behind" instead of android:screenOrientation="portrait". Basically, you created a dialog (in an activity) and dialog can't request orientation by itself it needs parent activity to do this (because a parent is visible in the background and has own layout).

"behind" The same orientation as the activity that's immediately beneath it in the activity stack.

Many people have given a fix, so I'll talk about the source of the problem.

According to the exception log：

The code that triggered the exception in Activity.java

    //Need to pay attention mActivityInfo.isFixedOrientation() and ActivityInfo.isTranslucentOrFloating(ta)
    if (getApplicationInfo().targetSdkVersion >= O_MR1 && mActivityInfo.isFixedOrientation()) {
        final TypedArray ta = obtainStyledAttributes(com.android.internal.R.styleable.Window);
        final boolean isTranslucentOrFloating = ActivityInfo.isTranslucentOrFloating(ta);
        ta.recycle();

        //Exception occurred
        if (isTranslucentOrFloating) {
            throw new IllegalStateException(
                    "Only fullscreen opaque activities can request orientation");
        }
    }

mActivityInfo.isFixedOrientation()：

        /**
        * Returns true if the activity's orientation is fixed.
        * @hide
        */
        public boolean isFixedOrientation() {
            return isFixedOrientationLandscape() || isFixedOrientationPortrait()
                    || screenOrientation == SCREEN_ORIENTATION_LOCKED;
        }
        /**
        * Returns true if the activity's orientation is fixed to portrait.
        * @hide
        */
        boolean isFixedOrientationPortrait() {
            return isFixedOrientationPortrait(screenOrientation);
        }

        /**
        * Returns true if the activity's orientation is fixed to portrait.
        * @hide
        */
        public static boolean isFixedOrientationPortrait(@ScreenOrientation int orientation) {
            return orientation == SCREEN_ORIENTATION_PORTRAIT
                    || orientation == SCREEN_ORIENTATION_SENSOR_PORTRAIT
                    || orientation == SCREEN_ORIENTATION_REVERSE_PORTRAIT
                    || orientation == SCREEN_ORIENTATION_USER_PORTRAIT;
        }

        /**
        * Determines whether the {@link Activity} is considered translucent or floating.
        * @hide
        */
        public static boolean isTranslucentOrFloating(TypedArray attributes) {
            final boolean isTranslucent = attributes.getBoolean(com.android.internal.R.styleable.Window_windowIsTranslucent, false);
            final boolean isSwipeToDismiss = !attributes.hasValue(com.android.internal.R.styleable.Window_windowIsTranslucent)
                                            && attributes.getBoolean(com.android.internal.R.styleable.Window_windowSwipeToDismiss, false);
            final boolean isFloating = attributes.getBoolean(com.android.internal.R.styleable.Window_windowIsFloating, false);
            return isFloating || isTranslucent || isSwipeToDismiss;
        }

According to the above code analysis, when TargetSdkVersion>=27, when using SCREEN_ORIENTATION_LANDSCAPE, SCREEN_ORIENTATION_PORTRAIT, and other related attributes, the use of windowIsTranslucent, windowIsFloating, and windowSwipeToDismiss topic attributes will trigger an exception.

After the problem is found, you can change the TargetSdkVersion or remove the related attributes of the theme according to your needs.

I can't agree to most rated answer, because

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

causes an error

java.lang.IllegalStateException: Only fullscreen opaque activities can request orientation

but this makes it works for me

<style name="TranslucentTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

and use it for your Activity, when you extends from

InterstitialActivity extends AppCompatActivity

in AndroidManifest.xml

    <activity
        android:name=".InterstitialActivity"
        ...
        android:screenOrientation="portrait"
        android:theme="@style/TranslucentTheme" />

Just remove this line android:screenOrientation="portrait" of activity in Manifiest.xml

That activity will get orientation from it's previous activity so no need to apply orientation which has <item name="android:windowIsTranslucent">true</item>.

in the manifest file set second activity parentActivityName as first activity and remove the screenOrientation parameter to the second activity. it means your first activity is the parent and decide to an orientation of your second activity.

<activity
        android:name=".view.FirstActiviy"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme" />

<activity
        android:name=".view.SecondActivity"
        android:parentActivityName=".view.FirstActiviy"
        android:theme="@style/AppTheme.Transparent" />

values-v26create styles.xml (v26)

<style name="Base.Theme.DesignDemo" parent="Base.Theme.AppCompat.Light">
    ...
    <!-- android 8.0(api26)，Only fullscreen opaque activities can request orientation -->
    <item name="android:windowIsTranslucent">false</item>
    ...
</style>

it seems when target sdk is pie (api level 28.0) and windowIsTranslucent is true

<item name="android:windowIsTranslucent">true</item>

and you try to access orientation. problem comes with android oreo 8.0 (api level 26) there are two ways to solve this

1. remove the orientation
2. or set windowIsTranslucent to false

if you are setting orientation in manifest like this

android:screenOrientation="portrait"

or in activity class like this

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

remove form both places.

and observed when u set windowIsTranslucent to true, it takes orientation from parent activity.

I had the same problem, and my solution was to eliminate the line

android:screenOrientation="portrait"

and then add this in the activity:

if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

Just Set Orientation of activity in Manifiest.xml

android:screenOrientation="unspecified"

It is a conflict (bug) between Themes inside style.xml file in android versions 7 (Api levels 24,25) & 8 (api levels 26,27), when you have

android:screenOrientation="portrait" :inside specific activity (that crashes) in AndroidManifest.xml

&

<item name="android:windowIsTranslucent">true</item> 

in the theme that applied to that activity inside style.xml

It can be solve by these ways according to your need :

1- Remove on of the above mentioned properties that make conflict

2- Change Activity orientation to one of these values as you need : unspecified or behind and so on that can be found here : Google reference for android:screenOrientation `

3- Set the orientation programmatically in run time

After doing some research, it seems that this problem may be due to a google bug. For me, I was able to leave this line in my Activities onCreate method:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

AND I changed my targetSdkVersion to 26. Having that line in my onCreate still resulted in a crash while my targetSdkVersion was still set at 27. Since no one else's solution has worked for me thus far, I found that this works as a temporary fix for now.

I faced this problem only in SDK 26 (8.0.0) if using windowIsTranslucent 'true' and forcefully setting orientation:

Here's the solution:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);   

        // fixing portrait mode problem for SDK 26 if using windowIsTranslucent = true
        if (Build.VERSION.SDK_INT == 26) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
        } else {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }        
    }



       <style name="SplashActivty" parent="AppTheme">
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowNoTitle">true</item>
    </style>



<!-- Splash screen -->
        <activity
            android:name="edu.aku.family_hifazat.activities.SplashActivity"
            android:label="@string/app_name"
            android:screenOrientation="unspecified"
            android:theme="@style/SplashActivty">

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

        </activity>

I was getting this error when I try to capture image or take image from gallery what works for me is to remove both

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

and

android:screenOrientation="portrait"

now my activity is using this theme:

  <style name="Transparent" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:colorBackgroundCacheHint">@null</item>
        <item name="android:windowAnimationStyle">@android:style/Animation</item>
        <item name="android:windowIsTranslucent">false</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:backgroundDimEnabled">false</item>
    </style>

only 8.0.0 throw the exception, above 8.0 has remove the exception

The only thing that worked for me was changing

android:screenOrientation="portrait"

to

android:screenOrientation="unspecified"

in the manifest for all translucent activities.

That way it is compatible with all API versions since the translucent activity seems to inherit its orientation from the parent activity as of targetApi: 28.

The style can be left as it is including <item name="android:windowIsTranslucent">true</item>.

I do not know if this is a bug from Google or an intended behavior but I (at least momentarily) solved it by changing compileSdkVersion and targetSdkVersion back to 26 in Gradle...

If you haven't resolved your problem just register the ad activity in the manifest like this:

<activity
android:name="com.google.android.gms.ads.AdActivity"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
tools:replace="android:theme"
 />

You also need to update to the latest version of the sdk.

Probably you showing Activity looking like Dialog(non-fullscreen), so remove screenOrientation from Manifest or from code. This will fix the issue.

this happened after 27,use targetSdkVersion 26 replace, wait for google fixed it

I've just removed the tags "portrait" from the non full-screen elements and everything went fine.

android:screenOrientation="portrait"

Use

android:screenOrientation="behind"

And Theme

<style name="translucent" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowBackground">#beaaaaaa</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowAnimationStyle">@android:style/Animation</item>
    <item name="android:typeface">normal</item>
    <item name="android:windowSoftInputMode">adjustPan</item>
    <item name="windowActionBar">false</item>
</style>

User extend AppCompatActivity & it will work !!

If the activity created by yourself, you can try this in the Activity:

@Override
public void setRequestedOrientation(int requestedOrientation) {
    try {
        super.setRequestedOrientation(requestedOrientation);
    } catch (IllegalStateException e) {
        // Only fullscreen activities can request orientation
        e.printStackTrace();
    }
}

This should be the easiest solution.

I had the same problem and I fixed it just by setting this: <item name="android:windowIsFloating">false</item> in styles.xml
