I set the c:/android-sdk/tools path to the path environment and commands like emulator is working just fine. But the adb command is still not recognized, what should I do ?
In the path system variable I added the android-sdk path and the tools path so far. Is there something else that needs to be done? Because commands like adb devices do not work. It says that the command is not recognized. By the way I want to do adb install comeapp.apk.
You have two ways:
First go to the particular path of Android SDK:
1) Open your command prompt and traverse to the platform-tools directory through it such as
$ cd Frameworks\Android-Sdk\platform-tools
2) Run your adb commands now such as to know that your adb is working properly :
$ adb devices OR adb logcat OR simply adb
Second way is :
1) Right click on your My Computer.
2) Open Environment variables.
3) Add new variable to your System PATH variable(Add if not exist otherwise no need to add new variable if already exist).
4) Add path of platform-tools directory to as value of this variable such as C:\Program Files\android-sdk\platform-tools.
5) Restart your computer once.
6) Now run the above adb commands such adb devices or other adb commands from anywhere in command prompt.
Also on you can fire a command on terminal setx PATH "%PATH%;C:\Program Files\android-sdk\platform-tools"
If you get your adb from Android Studio (which most will nowadays since Android is deprecated on Eclipse), your adb program will most likely be located here:
%USERPROFILE%\AppData\Local\Android\sdk\platform-tools
Where %USERPROFILE% represents something like C:\Users\yourName.
If you go into your computer's environmental variables and add %USERPROFILE%\AppData\Local\Android\sdk\platform-tools to the PATH (just copy-paste that line, even with the % --- it will work fine, at least on Windows, you don't need to hardcode your username) then it should work now. Open a new command prompt and type adb to check.
