当我滚动浏览我的 webview 应用程序时，我的应用程序冻结了

Question

该应用程序由一个简单的初始屏幕和 web 视图组成。但是到了webview端，就出现了应用卡顿的问题。当我滚动时它不完全工作。普通浏览器没有冻结。有什么问题

启动画面

    @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);



    }
}

我研究和分析了很多，但我找不到。该应用程序正在运行。但我认为它并不稳定。

我解决了问题。 android:hardwareAccelerated = 我添加了“true”清单文件，问题已解决。

<activity
            android:name=".MainActivity"
            android:hardwareAccelerated="true">
        </activity>
