I have everything, android sdk, eclipse, environment variables, setup on my Windows 7 machine. I follow the official guide from developer.android.com to run the MyFirstApp example. I tried command line and eclipse with AVD (virtual device). The emulator is running ok and the AVD is up . But I am stopped at the adb install step with the following error on both command line and eclipse: Code: E:\Workspace\MyFirstApp>adb install bin\MyFirstApp-debug.apk failed to copy 'bin\MyFirstApp-debug.apk' to '/data/local/tmp/MyFirstApp-debug.apk': No such file or directory My sdk is installed at a location without any white space in the path: "C:\Users\myname\AppData\Local\Android\android-sdk" I am on Windows. Why the error message is showing a linux style location, /data/local/tmp/MyFirstApp-debug.apk? I cannot use above command on Windows? Where the adb install try to install the apk to?
