Anyone know what could it be? Thanks for any help.

回答1:

If you are on windows try opening your Android Studio in Administrative Mode (Run as administrator)

回答2:

I encounter this problem before. I fixed this issue by killing or ending "monitior.exe" running process using Taskmanager in Windows. Then click ADM (Android Device Monitor) and it works

回答3:

I had the same issue with Mac OS X.

To solve it:

Open a terminal window
Navigate to your SDK
Locate the 'tools' folder
cd into it
run: sudo ./monitor
Type in your password

Good to go!

This is due to the error that the android device monitor not able to locate the jre so in order to solve this :

please follow the following Steps:

Step 1 : In your android studio find the jdk path, then inside jdk locate the jre and copy it. (In case of Linux jre is located inside android studio folder)

Step 2 : After copying jre paste it inside the (Android/Sdk/tools/lib/monitor-x86_64/) i.e monitor-x86_64 directory

I tried this for linux operating system, Android device monitor started well without any error.

Thanks, Hope this will help to someone!

This is the problem due to updating SDK tools Android SDK Tools

close the Android Studio
open the SDK Manager.exe from SDK folder
Now install Android SDK tool in my case tool is Rev.24.3.2
open Android Studio it will show new tool is available install it,install that one and try to restart it.

回答6:

No need to restart android-studio. Just do this:

Navigate to C:\Android\sdk\tools.
Find monitor.bat
Right-click and Run as administrator

回答7:

restart the studio and Run as administrator works for me.

回答8:

you don't need to restart android Studio only you need to open cmd as administrator and navigate to you SDK tools directory and write monitor in my case C:\Android\sdk\tools\monitor

回答9:

I had the same problem with my Android Studio 2.3.1 running on Ubuntu 14.04LTS. I was using openjdk 7. I updated it to openjdk 8 and viola! problem got solved.

回答10:

I used jdk-12 in Windows-10 platform, and kinda faced the same problem. This is what I did:

Changed the monitor.exe file's compatibility to "Run as Administrator"-- Didn't work
Checked if the java path (JAVA_HOME and PATH) variables are set, in the Environment Variables. --Didn't work
Finally uninstalled jdk-12 and installed jdk-8 and altered the path (JAVA_HOME and PATH) variables in Environment Variables. -- Worked!!!!! And then the adb opened without any error.
