Checkout java.lang.IllegalStateException: Only fullscreen opaque activities can request orientation | Android Oreo

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

            android:windowSoftInputMode="stateHidden|adjustResize" />


<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>

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.

Registering Static Broadcast receiver in Oreo | Android 8 Registering Static Broadcast receiver

There are some Broadcast Limitations in Oreo, it no longer supports to registering broadcast receivers for implicit broadcasts in app manifest. And NEW_OUTGOING_CALL is one of them, read here

You can use PHONE_STATE action for your purpose as it hasn’t categorized as a implicit broadcasts yet

public class StateReceiver extends BroadcastReceiver {

  public void onReceive(Context context, Intent intent) {
   // will trigger at incoming/outgoing call

    try {
        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
        String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
        String outgoingNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
    catch (Exception e){

In manifest,

        <receiver android:name=".StateReceiver">
            <action android:name="android.intent.action.PHONE_STATE" />

Also you need to add and check READ_PHONE_STATE permission
