Android应用启动至设备上的白屏

Question

我是Android开发人员的新手，我已经经历过类似的话题，但还没有帮助。 我创建了一个应用程序，该应用程序在添加扫描二维码的功能之前正在运行。 它可以在模拟器上运行，但是当我在三星设备上运行它时，它将启动到白屏，这就是我的日志所说的：

Launching app

Answer 1

这是由于冷启动问题。 请参阅https://developer.android.com/topic/performance/launch-time.html
如果在启动时执行大量初始化，则可能会发生这种情况。

Answer 2

将此添加到您的AndroidManifest.xml

<application>
    android:allowBackup="true"
    android:hardwareAccelerated="false"
    android:largeHeap="true"
</application>
