我制作的应用程序在我的手机上运行良好。当我在Google Play商店中将其作为alpha版本推出时，我遇到了一些内存不足错误的报告/崩溃。

发送的错误：

当我调试时，我注意到setButtonLessons有完整的101 json列表，这可能导致OOM崩溃。有没有办法可以在mayby 10的块中加载这个arraylist而不是整个json数组（101 atm但会变大）。

删除button.setBackgroundResource（R.drawable.buttonsoranje）;通过在其前面添加“//”，我更新了应用程序，并要求朋友进行测试。他带来了以下错误：

1 个答案:

答案 0 :(得分：1)

这种错误是由于drawble ressources所以问题是以下几行：

button.setBackgroundResource(R.drawable.buttonsoranje);
