建立失败：cordova建立android

Question

I'm newbie here for cordova & android.

I'm just trying to setup a project via commands.

    $ cordova create hello com.example.hello "HelloWorld"
    $ cd hello
    $ cordova platform add android

These all ran successfully. But when i go for `$ cordova build android` then it throws errors.

Can any one please suggest me where am i going wrong over here?

& please let me if you need any more info about it.

Answer 1

Have you added the environment variable? If not then add these...

• export PATH = ${PATH}:/.../platform-tools
• export PATH = ${PATH}:/.../tools
• export PATH = ${PATH}:/.../build-tools

You must place the correct path of your sdk.

Answer 2
