Popup over incoming-call screen

Question

I want to create a customized popup over the android's incoming call screen where I wish to add information for the user. I want the popup to not disable any clickability from the background so that the user could still answer the call.

I know it is possible since many applications do it, e.g. MeZeZe app: enter image description here

Some more information:

A translucent theme did not work since it cancels the former activity's clickability.
A toast is not an option - I don't want it to disappear.
I know there are many similar threads - I read many of them and none answer my specific problem.
I already know how to "make something happen" once a call is receiver, so no need for INCOMING_CALL activity tips.

Would appreciate any help! Thanks

Can you share your solution for this? Maybe on github? Thanks! — albertosh, Jan 12 '13 at 00:11

Consider this alternate solution: [Provide the caller id for incoming call from my own app](https://stackoverflow.com/questions/48870782/provide-the-caller-id-for-incoming-call-from-my-own-app/57733654#57733654) — Jacob Michaelis, Sep 04 '19 at 14:38

If you want to keep the Call activity still clickable, but not have any controls on your overlay, you can do this by calling

getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);

In the onCreate() method of the activity that is shown over the call.

The layout parameters useable together with this are:

android:windowBackground="@android:color/transparent" 
android:windowIsTranslucent="true" 
android:windowAnimationStyle="@android:style/Animation.Translucent"

Is there any way I can take control of the complete screen so I have a customized incoming screen? – user1163234 Mar 05 '12 at 12:31
Hi, I have an issue. If i get a call while in my app ( ie any of the view of an activity in my app is in focu ) this is not working properly. The android incoming call screen comes and disappears , with my app activity window displayed and whatever screen overriding i am doing, that is also visible. Please help – png Jun 06 '12 at 11:04

This worked for me with a few additions:

In the BroadcastReceiver I added the following lines to the intent:

        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

Furthermore, I added a delay of roughly 1.5 seconds before I fire PopupWindow activity to make sure it is coming after the incoming call system screen.

In the Manifest file I added:

<activity android:name=".PopUpIncomingCallActivity" 
          android:theme="@android:style/Theme.Translucent">

</activity>

to make sure that the layout of the Popup screen is translucent.

In the Popupscreen layout xml file I added the following propperties:

    android:windowAnimationStyle="@android:style/Animation.Translucent"
    android:windowBackground="@android:color/transparent"
    android:windowIsTranslucent="true"

However this solution still has a drawback:

The Popup screen appears above the incoming call system screen and therefore a user has to perform an action (such as clicking a button, pressing a key or touching the screen) to close the Popup screen, as the incoming call screen remains underneath and is not accessible until the popup screen is closed.

It will not only show the activity on lock screen but will also allow to receive an incoming call behind your activity screen.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    final Window win = getWindow();
    win.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
            | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
    win.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
            | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
    win.addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);

    setContentView(R.layout.activity_main);
