ANDROID_HOME set to non-existent path when trying to run

unmind4@unimind4-MS-7850:~/groshi$ meteor run android
                                              
Your system does not yet seem to fulfill all requirements to build apps for
Android.
                                              
Please follow the installation instructions in the mobile guide:

Status of the individual requirements:        
✓ Java JDK                                    
✗ Android SDK: 'ANDROID_HOME' environment variable is set to non-existent path:
  ~/Android/Sdk
  Try update it manually to point to valid SDK directory.
✗ Android target: Android SDK not found. Make sure that it is installed. If it
  is not at the default location, set the ANDROID_HOME environment variable.
✗ Gradle: Could not find gradle wrapper within Android SDK. Might need to
  update your Android SDK.
  Looked here: ~/Android/Sdk/tools/templates/gradle/wrapper
unmind4@unimind4-MS-7850:~/groshi$ cd ~/Android/Sdk
unmind4@unimind4-MS-7850:~/Android/Sdk$ ls
build-tools  extras   platforms       skins          tools
emulator     patcher  platform-tools  system-images

Not sure about the second error as the path seems to be fine. The path mentioned in the gradle error however does not exist.
