java.lang.OutOfMemoryError用4张图片开发应用程序

Question

所以我正在尝试学习Android开发，我试图在ConstraintLayout中开发“Netflix App”，由于某些原因我的应用程序崩溃并且我得到了所有这些错误，我检查了照片的大小，它们都少了那么1mb

希望你们能解释一下并解决我的错误。

禁用高级Android分析器为我做了诀窍。您可以按如下方式禁用它：

转到运行/调试配置 - ＆gt;分析 - ＆gt;取消选中启用高级分析

Answer 2

您正在加载的图像太大，占用太多内存来加载它们。 你可以尝试https://developer.android.com/topic/performance/graphics/load-bitmap 我建议使用库来加载图像，如Glide或Picasso。
