运行此行代码时出现Out Of Memory异常

private val TAG = KotlinFilePicker()::class.java.canonicalName

并且在禁用时它工作正常

有人可以用这种方式指出出错了吗

Answer 1

不应该

private val TAG = KotlinFilePicker::class.java.canonicalName

代替？

由于您的stacktrace声明如下：

Failed to allocate a 170 byte allocation with 68 free bytes and 68B until OOM" (recursive case)

这意味着我们在这里有无尽的递归。仔细看看代码，我们看到你创建了一个类的实例，它试图创建TAG属性，然后创建KotlinFilePicker的另一个实例......直到所有内存耗尽

Answer 2

您正在创建一个新的KotlinFilePicker()，它拥有自己的TAG，可以创建新的KotlinFilePicker()等。

要修复它，请使用KotlinFilePicker::class.java.canonicalName。

使用Kotlin :: class.java.canonicalName时出现OutOfMemory异常
