            android:launchMode="singleTop">
            <intent-filter>
                <action android:name="intent.to.front" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
    </application>

So if you know answer, please help and why is it only happening to xperia device?

Answer 1

Lollipop devices add there own square to notification icons. You need to make sure that your image has an alpha background so when a color fill is applied to it, you can still see the image.

If you still want it to appear as it does on older devices you can do some checking code to see what version of Android they are running and supply a different icon.

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {

}
