Java 将映射键集转换为字符串数组时出现OOM错误-Android

我有下面的课

class Util {
  private static Map<String, String> params;

  public static String getSignedUrl(Context context) {
    params= null; // reset previous instance
    params= new HashMap<>();
    ...
    addDefaultParams();
    addCustomParams();
    String signedUrl = getSignedUrl();
    ....
    return signedUrl;
  }

  private static String getSignedUrl() {
     String[] keyArray = params.keySet().toArray(new String[0]); // OOM error here!
     .....
     return signedUrl;
  } 

  private static void addDefaultParams() {
    //add some default params
    params.add(key, value);
  }

  private static void addCustomParams() {
    //add some custom params
    params.add(key, value);
  }

}

这是因为

params

是一个静态字段吗？。但我正在重置

params

的上一个实例，因此我不确定这会导致OOM问题

在此方面的任何帮助都将不胜感激。提前谢谢

您可以向我们显示错误消息吗？在此处发布错误堆栈。无法添加整个堆栈跟踪，但添加了部分堆栈跟踪@deHaar@AmitTiwary编辑如果使用多个线程，则代码和数据将不是线程安全的。
