With 25rc1 of the SDK tools I am having a problem when starting the emulators from $PATH
➜ ~ which emulator /home/ligi/bin/android-sdk/tools/emulator ➜ ~ emu
Do not use $ANDROID_HOME/tools/emulator, it will cause error when you launch every time unless you change dir.
$ANDROID_HOME/tools/emulator
There is a another emulator in $ANDROID_HOME/emulator.It is a good choice
$ANDROID_HOME/emulator
