ChatHead服务在Nexus设备上的Lollipop和Marshmallow中不起作用

Question

I am Working on a service which will draw a overlay icon on some predefined applications eg WhatsApp, FB Messenger, Instagram etc. we set their packages predefined so that our service can detect.

*Its Working Totally Fine on till 19API (Before and Equal to Kitkat Api level)

But its not working on Lollipop and Marshmallow we are testing on Nexus 5,6,5x,6p and Hawaii Devices P8.

in these devices we got error E/Surface: getSlotFromBufferLocked: unknown buffer: 0x9db36030

Don't Know what does it mean and what the issue behind. Please Help me Here is my Service Code below

Any Help would be great...

For Lollipop:

it works for me. But You have to add this permission in your mainfest.

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

Anyway you can check if you got the permission before drowing:

if (Settings.canDrawOverlays(context)) {
    // Here you go, you can draw you chathead view
}

For Marshmallow

Since it needs an extra permission, It does not work directly. I tried to find the settings and send user there. I found that you can send the user from your app directly to the permission page in the settings with this intent .

ACTION_MANAGE_OVERLAY_PERMISSION

montioned on in the documentation of Settings.canDrawOverlays(context) page

UPDATE: This is the documentation of canDrawOverlays :

Checks if the specified context can draw on top of other apps. As of API level 23, an app cannot draw on top of other apps unless it declares the SYSTEM_ALERT_WINDOW permission in its manifest, and the user specifically grants the app this capability. To prompt the user to grant this approval, the app must send an intent with the action ACTION_MANAGE_OVERLAY_PERMISSION, which causes the system to display a permission management screen.

Hope this helps.
