Android Device Monitor will not start

Android Device Monitor fails to start with an error message that says to read the log file. However, the log file has a lot of information that is impossible to interpret without a better understanding of the program. Several people seem to have posted a similar question, but I can't find any useful answer.

On Windows 7 64 bit, I have Android Studio 1.0.2 and Eclipse Luna installed, both in 64 bit versions. Each have their own Android SDK installed. Everything in both environments seems to be working normally. I have Jre7 64 and jdk7 64 installed, and also jre7 32 for a separate program that requires the 32 bit java. JAVA_HOME is set to "C:\Program Files\Java\jre7" and the first path in the PATH variable is "C:\Program Files\Java\jre7\bin".

I am unable to start the device monitor from the tools directory of either SDK installation using the monitor.bat file. I am also unable to start the device monitor from it's 64 bit sub-directory using the monitor.exe file directly, which is what the batch file calls anyway.

This one has me completely stumped. Everything seems to be installed and working correctly. I am reluctant to spend hours trying various possible solutions, such as removing and reinstalling java, removing and installing the Android SDK, etc. when I have low confidence in those solving the issue. I've already spent a good bit of time trying to find an answer. If anyone can shed some light on this, it would be great.

Regards

try to modify your monitor.ini file present in tools/lib/monitor-x86 folder. First of all backup it, then replace the content of this file with

-Xms256m
-Xmx512m

Now rerun monitor.bat. Hopefully this will fix your issue.

I was also facing the same problem. I have also tried running Android device monitor via monitor.bat but i get the following error in the log file

  1. Make sure the JAVA_HOME environment variable refers to the correct Java Runtime Environment location on your C:\ drive.
  2. Make sure you launch the 64-bit verions of Eclipse or Android Studio.
