The application consists of a simple splash screen and webview. But when it comes to the webview side, there is a problem of freezing in the application. It doesn't work exactly when I scroll. There is no freeze in the normal browser. What is the problem
Splash Screen

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
startActivity(new Intent(SplashScreen.this,MainActivity.class));
finish();
}
}, 1200);
}
}

I researched and analyzed a lot but I couldn't find
Try enabling hardware acceleration in manifest in your activity
android:hardwareAccelerated="true"
