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 reques
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>
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 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...
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())
//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>
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>
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.
