我正在尝试让我的应用程序向firebase发送信息，首先它允许它将信息发送到firebase，但是第二次它显示了一条消息 “跳过n＃frames！应用程序可能在其主线程上做了太多工作。”和“后台并发复制GC释放185001（8MB）AllocSpace对象，0（0B）LOS对象，31％免费，12MB / 18MB ......”。
这个主要功能是发送有关游戏的信息，如果它的按钮已经长时间点击（OnLongClickListener）。
此函数的java文件是：

并检索这些信息。
UserFavESport.java
public class UserFavESport {

}
public UserFavESport(String favEsports, String favEsportsDev, String favEsportsRel, String favEsportsGenre, String favEsportsImg) {

this.favEsportsRel = favEsportsRel;
this.favEsportsGenre = favEsportsGenre;
this.favEsportsImg = favEsportsImg;
}
public String getFavEsports() {
return favEsports;
}
public void setFavEsports(String favEsports) {
this.favEsports = favEsports;
}
public String getFavEsportsDev() {
return favEsportsDev;
}
public void setFavEsportsDev(String favEsportsDev) {
this.favEsportsDev = favEsportsDev;
}
public String getFavEsportsRel() {
return favEsportsRel;
}
public void setFavEsportsRel(String favEsportsRel) {
this.favEsportsRel = favEsportsRel;
}
public String getFavEsportsGenre() {

}
public void setFavEsportsGenre(String favEsportsGenre) {

}
public String getFavEsportsImg() {
return favEsportsImg;
}
public void setFavEsportsImg(String favEsportsImg) {
this.favEsportsImg = favEsportsImg;
}
}
对此的任何帮助将不胜感激。

错误＆＃34;应用程序可能在其主线程上做了太多工作＆＃34;告诉你在主线程上做了很长时间的操作。我们应该总是避免在主线程上执行长操作，而是在后台线程上执行。除了在按钮的长按单元监听器中显示toast之外，所有代码都应该是新线程而不是主线程。只需在click侦听器方法中创建一个新线程，并将此工作委托给新线程。
如果要将结果传回UI线程，可以使用Thread和Runnable处理主线程数据或使用Async任务。
