Android Studio - Can not open device monitor

Question

I just downloaded Android Studio and it seems to import my existing Eclipse project well.

However, if I try to open "Android Device Monitor" I get the message "An error has occurred" with a reference to a log file.

My log file is included underneath. I am not sure why there is a reference to "Eclipse" int it? Anyhow, all in all, I have no idea where to go from here

Answer 1

1. Install JRE into C:\Java\jre folder.
2. Copy monitor-x86_64 folder from *C:\Users\User%Name\AppData\Local\Android\Sdk\tools\lib* to *C:\Java*.
3. Copy jre folder from C:\Java\jre to C:\Java\monitor-x86_64\jre.
4. Set PATH C:\Java\monitor-x86_64\jre\bin.
5. Run C:\Java\monitor-x86_64\monitor.exe as administrator.
6. PROFIT!

Answer 2

alternatively simple :

1.do several times

taskkill /IM monitor.exe

until one process remains and "can never be killed".

2.open task manager

find the monitor and expand it with PLUS + sign

you will find a message with a fail or similar

right click and select "kill"

3. then, immediately monitor GUI will appear on your screen, as if something was preventing it to be visible.

Answer 3

win10 x64 - i had java 9.0.1, android device monitor was crashing all the time.

then i removed this java version from system and installed java 8 (u151), it helped

if you have multiple java installations - check the PATH variable, the monitor looks up for javaw.exe file, and if it's version doesnt work with monitor - it crashes

Answer 4

The solution posted in the following link worked for me. I added the answer below, but you can take a look at the link for more information. Also, I am using Windows 8 and it worked as well.

This is what I had to do to resolve it in Windows 7 64 bit:

1. Run the task manager
2. End the process for monitor
3. Also end the java processes. Just doing monitor won't do the trick.
4. Relaunch the monitor. Now it runs.
