Hi guys, I'm making an small app for a client and he want to protect the images showed from an screen capture.

Can I detect the ScreenCapture Method to show an Imageview for protect the real image?

My Banks mobile app does this. I'm not sure how it is implemented though.

My Banks mobile app does this. I'm not sure how it is implemented though.

I'm thinkin on intercept the key Volume and I dont know if the powerKey will intercept.
If I will intercept both the show an ImagenView for 2 o 3 Seconds saying, "You Cannot Make screenshots from our App".

But I'm asking before to start it, maybe has a better way to do it.
I found this https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#setScreenCaptureDisabled(android.content.ComponentName, boolean)

But I dont know how to use setScreenCaptureDisabled()

Volume key isn't the only way to take a screenshot. My Xiaomi has a soft button in the notification drawer.

Im sure someone will be able to explain how to use setScreenCaptureDisabled.

Maybe Found the solución here:
https://www.b4x.com/android/forum/threads/disable-screen-capture-functionality.35753/

I go to try.

I confirmed this solution work on my device. Just Insert this code starting the Activity_Create

Sub Activity_Create(FirstTime As Boolean)
#If Java
import android.annotation.TargetApi;
import android.content.Context;
import android.view.WindowManager.*;
public void _onCreate() {
    this.getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);
}
#End If

When I try to capture, show a message saying Can't capture, maybe memory is full.
Or something like that.
