'while' statement cannot complete without throwing an exception

You are probably using Android Studio or IntelliJ.

If so, you can add this above your method containing the infinite loop to suppress warnings:

@SuppressWarnings("InfiniteLoopStatement")

　　

Or add this "magic" comment above the statement:

//noinspection InfiniteLoopStatement

　　

This will tell the IDE that this is ok.

More generally, when you get a false positive warning, do Alt+Enter and do what showed on the screenshot below (select class only if your class is full of false positive, for the same warning)

有時候這個告警是多余的，例如我們手寫的監控線程。

如果有消除告警強迫症。在線程的執行方法上加入注解。

@SuppressWarnings("InfiniteLoopStatement")
public void run() {
    ...
}
