error
JAVA_HOME is not set and no 'java' command could be found in your PATH.
cause
user variable were set via the control panel but the system variable not in sync, had to set as admin in command prompt


solution
https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html

dependencies for windows
  • java sdk (same version as the jre within the android sdk folder), android has the jre but lacks the jdk
  • android studio (android runs on java)
  • paths and windows environment variable must be set
and then you can use the react-native cli on vscode

  1. command prompt terminal choco install -y nodejs.install openjdk8
  2. browser search and install android studio
  3. android studio app > config>sdk manager> sdk> check for android 10 q else add
  4. control panel pane set ANDROID_HOME, the url is inside the sdk manager
  5. command prompt terminal set JAVA_HOME, it should be under c:/programme files/java
  6. control panel pane set the PATH for android home > platform tools and java home>bin (where the java file is)
  7. vscode terminal npm i -g react native cli
  8. vscode terminal npx react-native init [name]
  9. vscode terminal react-native run-android

(actually not very expensive i guess, she is into expensive gifts). ms prettii and mr suave ever played accidental touch ( hand brushing as they both reached for the mouse, then longing looks). she sent him a sticker of fingers touching on group chat before. anyway suave decided to teach us newbies coding in chinese (cos ...

this just came out. his recent songs are getting better, i'm impressed. metaphors and imagery on point. flying, running barefoot, looking back, blackened nails, tears in sleep, warm bright sunlight, dancing alone, flying free like a bird i relate to this because my life is to be honest, so-so in the friends department and non existent in the romance department.  i don't feel like really sad, or regret, or i need to change it. friends are busy and settled down,  some are less able to provide a listening ear (maybe to them it is childish, immature, or being listened to means you have have to reciprocate so maybe not, they have theirs at home already, they are stressed and have no more bandwidth for anything else).  that is the reality of being an adult. maybe the occasional sympathy and warmth from a colleague or friend or stranger. but that doesn't do it for me. i don't need the superficial. and i feel it is so easy to have values not align one day, or per...
