How to disable default incoming call/text notification?

Question

I want to disable incoming call and text notification and use my app to show notification.

Logic is that my app will stay in background and on incoming call/text my app will popup with a page where I will show notification.

Please can anyone help me how Can I disable default incoming call/text notification.

Basically you want to override other apps notification functionality and use your app to display their notifications? — Ümañg ßürmån, Aug 21 '18 at 10:09

I was able to hide incoming call notifications by using full screen activity. incoming call notification is not visible only activity is visible.

obviously you need to create service to detect incoming call which will launch your activity.

Here is code I used for full screen activity

protected void onCreate(Bundle savedInstanceState) {
        this.getWindow().getDecorView().setSystemUiVisibility(getSystemUiFlags());

        setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

        super.onCreate(savedInstanceState);
        if (Build.VERSION.SDK_INT < 16) {
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }
        setContentView(R.layout.myviewxml);
}

the function

private static int getSystemUiFlags() {
    return View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_IMMERSIVE
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN;
}

The manifest entry

    <activity
        android:name=".MyActivity"
        android:label="@string/title_activity"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar"></activity>

Hope this helps somebody.
