无法打开Android设备监视器-重新安装？

Question

Like others, when I open Android Device Monitor I get the error:

"An error has occurred. See the log file C:\\Users\\Me.android\\monitor-workspace.metadata.log."

When I looked in the log file, the error was:

!MESSAGE Unhandled event loop exception
!STACK 0
java.lang.NullPointerException
    at com.android.ddmuilib.logcat.LogCatPanel.updateUnreadCount(LogCatPanel.java:1212)

I tried some quick solutions others found:

• Running as Administrator (I'm on Windows)

• echo $JAVA_HOME outputs a location (and I think it's there), but need to check this out more

This worked until just yesterday, so I am worried I may have accidentally uninstalled or deleted something (just did some clean-up).

How can I reinstall Android Device Monitor?

Answer 1

I opened SDK Manager and deleted the most recent 3 tools, then I reinstalled them. That seems to have fixed it. It did take a while, so it might be worth trying only uninstalling the most recent set of tools.
