Question

我正在开发一个Android应用程序，现在我发现我的应用程序仅适用于API 22及更高版本的设备。在API小于22的所有设备（虚拟）中，它几乎在启动后立即崩溃（没有响应）。我想这是因为内存不足而发生的。

如果我在＆＃34; Memory＆＃34;上查看Android监视器（在Android Studio中）图我可以看到 this，和 this

看起来android有足够的内存，但没有时间分配

如何在我的代码中找到确切的位置？

Answer 1

如何在我的代码中找到确切的位置？ - 调试！

深度调试后，我猜我发现了什么问题。问题是我使用了自定义的ImageView并且占用了太多内存，因此我将尝试改进我的自定义ImageView。

由于内存不足，Android应用程序无法响应
