Question

我是Android开发人员的新手，我已经经历了类似的主题，但还没有帮助。我创建了一个应用程序，它在我添加扫描QR码的功能之前就已经运行了。它可以在模拟器上运行但是当我在我的三星设备上运行时，它会启动到白色屏幕，这就是我的日志所说的：

Answer 1

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

Answer 2

将此添加到

中的AndroidManifest.xml

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