React native environment Creation (NODEJS Environment) development of Android environment

(1)

Installation: NPM install-g REACT-NATIVE-CLI

REACT-NATIVE-CLI is a command-line tool for developing react native

The above line of code will help you install the react-native command in terminal. Of course, you only need to run this line of code once.

(2)

The react-native command line has trouble dragging code from NPM's official source for well-known network reasons. Please replace the NPM repository source with a domestic mirror:

set registry https://registry.npm.taobao.org --globalnpm config set disturl https://npm.taobao.org/dist --global

Also, remember to precede the init with 不要 sudo (otherwise the directory owner of the new project becomes root instead of the current user, causing a series of permissions problems, use Chown fix).

(3) withreact-native init AwesomeProject 出现不成功，类似的“Uncaught Error: EPERM: operation not permitted,” 表示的 权限错误

Add an as administerator to the back.

(4)

npm install --save [email protected]  最后一个版本；node 升级

1, the key that generated the signature

This process will be used keytool , the development of Android should have been exposed to the thing. See Key and certificate management tools for details.
Execute in the main directory of the project:

keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000[注：在产生的时候需要提供密钥和存储密码，后续会用到]mv my-release-key.keystore android/app/

2, modify android/gradle.propertiesFile, add the following

MYAPP_RELEASE_STORE_FILE=my-release-key.keystoreMYAPP_RELEASE_KEY_ALIAS=my-key-aliasMYAPP_RELEASE_STORE_PASSWORD=xxMYAPP_RELEASE_KEY_PASSWORD=xx[注意替换xx为你自己设置的密钥和存储密码]

3, modify android/app/build.gradleSignature configuration in the file:

...android {   ...   defaultConfig {     ...   }   signingConfigs {     release {         storeFile file(MYAPP_RELEASE_STORE_FILE)         storePassword MYAPP_RELEASE_STORE_PASSWORD         keyAlias MYAPP_RELEASE_KEY_ALIAS         keyPassword MYAPP_RELEASE_KEY_PASSWORD     }   }   buildTypes {     release {       ...       signingConfig signingConfigs.release     }   }}

4, then go to Android directory to do the following:

./gradlew assembleRelease

will be at the end android/app/build/outputs/apk/app-release.apk .

Before each execution, be careful to delete the apk.

Failed to read key from KeyStore This problem, is because the configuration of the wrong, fuck find the wrong exhausted;

Release {
StoreFile file ("Release.keystore")
Storepassword ' 111111 '
Keyalias ' Alias_name '
Keypassword ' 111111 '
}
Debug {
StoreFile file ("Release.keystore")
Storepassword ' 111111 '
Keyalias ' Alias_name '
Keypassword ' 111111 '
}
