I am facing the problem while retrieving the contacts from the contact book in Android 8.0 Oreo java.lang.IllegalStateException: Only fullscreen opaque activities can request orientation
I am trying to get the contact in my activity from the phone contact book and it works perfect for Lollipop, Marshmallow, Nougat, etc but it will gives me the error for Oreo like this please help me. My code is here below.
Demo Code :-
private void loadContacts() {
contactAsync = new ContactLoaderAsync();
contactAsync.execute();
}
private class ContactLoaderAsync extends AsyncTask<Void, Void, Void> {
private Cursor numCursor;
#Override
protected void onPreExecute() {
super.onPreExecute();
Uri numContacts = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String[] numProjection = new String[]{ContactsContract.CommonDataKinds.Phone.CONTACT_ID, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.TYPE};
if (android.os.Build.VERSION.SDK_INT < 11) {
numCursor = InviteByContactActivity.this.managedQuery(numContacts, numProjection, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC");
} else {
CursorLoader cursorLoader = new CursorLoader(InviteByContactActivity.this, numContacts, numProjection, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC");
numCursor = cursorLoader.loadInBackground();
}
}
#Override
protected Void doInBackground(Void... params) {
if (numCursor.moveToFirst()) {
try {
final int contactIdIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID);
final int displayNameIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
final int numberIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
final int typeIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE);
String displayName, number, type;
do {
displayName = numCursor.getString(displayNameIndex);
number = numCursor.getString(numberIndex);
type = getContactTypeString(numCursor.getString(typeIndex), true);
final ContactModel contact = new ContactModel(displayName, type, number);
phoneNumber = number.replaceAll(" ", "").replaceAll("\\(", "").replaceAll("\\)", "").replaceAll("-", "");
if (phoneNumber != null || displayName != null) {
contacts.add(phoneNumber);
contactsName.add(displayName);
contactsChecked.add(false);
filterdNames.add(phoneNumber);
filterdContactNames.add(displayName);
filterdCheckedNames.add(false);
}
} while (numCursor.moveToNext());
} finally {
numCursor.close();
}
}
Collections.sort(contacts, new Comparator<String>() {
#Override
public int compare(String lhs, String rhs) {
return lhs.compareToIgnoreCase(rhs);
}
});
InviteByContactActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
mContactAdapter.notifyDataSetChanged();
}
});
return null;
}
}
private String getContactTypeString(String typeNum, boolean isPhone) {
String type = PHONE_TYPES.get(typeNum);
if (type == null)
return "other";
return type;
}
static HashMap<String, String> PHONE_TYPES = new HashMap<String, String>();
static {
PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_HOME + "", "home");
PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE + "", "mobile");
PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_WORK + "", "work");
}
}

In android Oreo (API 26) you can not change orientation for Activity that have below line(s) in style
<item name="android:windowIsTranslucent">true</item>
or
<item name="android:windowIsFloating">true</item>
You have several way to solving this :
1) You can simply remove above line(s) (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 your activity (in onCreate())
'>=' change to '!=' thanks to Entreco comment
//android O fix bug orientation
if (android.os.Build.VERSION.SDK_INT != Build.VERSION_CODES.O) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
3) You can create new styles.xml in values-v26 folder and add this to your style.xml. (Thanks to AbdelHady comment)
<item name="android:windowIsTranslucent">false</item>
<item name="android:windowIsFloating">false</item>
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.
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.
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.
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.
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.
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.
If you have to use setRequestedOrientation(), there is no way but sacrifice the windowIsTranslucent attribute on Android 8.0
values\styles.xml for api level 25- (<8.0)
<style name="Base.Theme.DesignDemo" parent="Base.Theme.AppCompat.Light">
...
<item name="android:windowIsTranslucent">true</item>
...
</style>
values-v26\styles.xml for api level 26 (=8.0)
<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>
values-v27\styles.xml for api level 27+ (>8.0)
<style name="Base.Theme.DesignDemo" parent="Base.Theme.AppCompat.Light">
...
<item name="android:windowIsTranslucent">true</item>
...
</style>
Many people have given a fix, so I'll talk about the source of the problem.
According to the exception log：
Caused by: java.lang.IllegalStateException: Only fullscreen opaque activities can request orientation

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(

}
}
mActivityInfo.isFixedOrientation()：
/**

*/
public boolean isFixedOrientation() {
return isFixedOrientationLandscape() || isFixedOrientationPortrait()
|| screenOrientation == SCREEN_ORIENTATION_LOCKED;
}
/**

boolean isFixedOrientationPortrait() {
return isFixedOrientationPortrait(screenOrientation);
}

final boolean isSwipeToDismiss = !attributes.hasValue(com.android.internal.R.styleable.Window_windowIsTranslucent)

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>.
Just Set Orientation of activity in Manifiest.xml
android:screenOrientation="unspecified"
OR for restricted to Portrait Orientation
You can also use in Activity, In onCreate method call before super.onCreate(...) e.g.
#Override
protected void onCreate(Bundle savedInstanceState) {
setOrientation(this);
super.onCreate(savedInstanceState);
setContentView(R.layout.your_xml_layout);
//...
//...
}
// Method
public static void setOrientation(Activity context) {
if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.O)
context.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
else
context.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
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
remove the orientation
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.
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" />
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);
}
I recently faced the issue and here's the solution.
No need to change the screen orientation parameter which you set at android manifest file.
Just add two folders in
res>values
as res>values-v26
and res>values-v27
Then copy your styles.xml and themes.xml file there.
and change the following parameters from TRUE to FALSE.
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowIsTranslucent">false</item>
It will work.
A common bug of Android 8.0
some of the answers wasnt clear for me and didnt work,
so this was causing the error:
<activity
android:name=".ForgotPass_ChangePass"
android:screenOrientation="portrait" <--- // this caused the error
android:windowSoftInputMode="stateHidden|adjustPan|adjustResize"/>
android studio was suggeting to set screenOrientation to fullSensor
android:screenOrientation="fullSensor"
yes this will fix the error but i wan to keep my layout in the portrait mode, and fullSensor will act based on the sensor
"fullSensor" The orientation is determined by the device orientation
sensor for any of the 4 orientations. This is similar to "sensor"
except this allows any of the 4 possible screen orientations,
regardless of what the device will normally do (for example, some
devices won't normally use reverse portrait or reverse landscape, but
this enables those). Added in API level 9.
source: android:screenOrientation
so the solution that worked for me i used "nosensor" :
<activity
android:name=".ForgotPass_ChangePass"
android:screenOrientation="nosensor"
android:windowSoftInputMode="stateHidden|adjustPan|adjustResize"/>
"nosensor" The orientation is determined without reference to a
physical orientation sensor. The sensor is ignored, so the display
will not rotate based on how the user moves the device.
see android documentation here
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.
only 8.0.0 throw the exception, above 8.0 has remove the exception
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
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>
Probably you showing Activity looking like Dialog(non-fullscreen), so remove screenOrientation from Manifest or from code. This will fix the issue.
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>
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 resolved this issue by removing android:screenOrientation="portrait" and added below code into my onCreate
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
while my theme properties are
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowDisablePreview">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.
this happened after 27,use targetSdkVersion 26 replace, wait for google fixed it
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 don't want to post since it seems simple. For the sake of simplicity I'll provide as much detail as I can without throwing up a bunch of logcat and expecting a cure all.
Following the google tutorial for styling an action bar. Win7, Android Studio, Android 5, API 19 KitKat (Min SDK Version 11) no support library, Gradle 1.8 I think.

}
#Override

// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will

WHAT I'VE TRIED:
Normally in the onCreate I would put super.onCreate(savedInstanceState);However, when I debug that line is the one that throws the error so some other people on SO commented it out to not inherit the previous overriden onCreate. I did the same
setContentView(R.layout.activity_main); Also gives me an error when debugging. Checked the manual, they said that you must define the ListView if it gives you an error like that. But I'm not using a listview, I only defined TextView Therefore, I commented it out
I changed my style from <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> to <style name="AppTheme" parent="Theme.AppCompat.Light">
Other than that I pretty much followed the tutorial exactly to my project. If I could just identify what all these problems mean that would be great (SO is always a last resort I may just skip this tutorial). Thanks so much
EDIT CustomActionBarTheme from themes.xml:
<!-- Theme applied to app/activity -->
<style name="CustomActionBarTheme"
parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/MyActionBar</item>
<item name="actionBarStyle">#style/MyActionBar</item>
</style>
First of all in your onCreate method:
you have to call the super method
you have to define your layout with setContentView method
you have to use the getSupportActionBar() instead of getActionBar method
Something like:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
Then you have to change the style CustomActionBarTheme used by your MainActivity, because the ActionBarActivity requires an AppCompat theme
<!-- Theme applied to app/activity -->
<style name="CustomActionBarTheme"
parent="Theme.AppCompat.Light">
......
</style>
Finally I suggest you switching to the new app-compat v 22.2.0 changing your build.gradle
dependencies {
compile 'com.android.support:appcompat-v7:22.2.0'
}
With this version the ActionBarActivity is deprecated. You can use now the AppCompatActivity
For Theme.AppCompat you need to include the support library in your gradle.build file:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
}
Additionally ActionBarActivity is deprecated, use AppCompatActivity
The reason you are having this problem is because the activity you are trying
to apply the theme to is extending ActionBarActivity which
requires the AppCompat theme to be applied.
Change the parent of the actual java code to be just plain Activity and
you should be able to leave the theme on it.
