npm install --save react-native-vector-icons
npm install --save native-base
npm install --save react-native-calendars
npm install --save react-native-multiple-select

LANCER ANDROID

react-native run-android

Si probleme
android {
defaultConfig {
ndk {
abiFilters 'armeabi-v7a', 'x86'
}
}
}

SI problème, lancer une première fois le projet avec android studio et compiler, ça installera ce qu'il manque.
et créer un virtual device si necessaire
Si autre probleme
lancer a la main le bundler :

react-native start -- -reset-cache

Si tout merde

rm node_modules\react-native\local-cli\core__fixtures__\files\package.json
cd android    ./gradlew clean
rm -rf node_modules    npm install

pour debuger via adb (permet de voir les causes de plantage des version release par exemple)

adb logcat *:E

LANCER IOS

react-native run-ios

emacs ios/gextrareact/Info.plist

(ajouter ou modifier si ça existe ! en général il y a une règle localhost)

RENAME PROJECT ID ANDROID

I've changed project subfolder name from:

"android/app/src/main/java/MY/APP/OLD_ID/"

to:

"android/app/src/main/java/MY/APP/NEW_ID/"

Then manually switched the old and new package ids:
In: android/app/src/main/java/MY/APP/NEW_ID/MainActivity.java:

package MY.APP.NEW_ID;

In android/app/src/main/java/MY/APP/NEW_ID/MainApplication.java:

package MY.APP.NEW_ID;

In android/app/src/main/AndroidManifest.xml:

package="MY.APP.NEW_ID"

In android/app/BUCK:

android_build_config(
    package="MY.APP.NEW_ID"
)
android_resource(
    package="MY.APP.NEW_ID"
)

And in android/app/build.gradle:

applicationId "MY.APP.NEW_ID"

Gradle' cleaning in the end (in /android folder):

./gradlew clean

RENAME PROJECT NAME ANDROID

In package.json

"name" : "gextranet",

In index.js

AppRegistry.registerComponent('gextranet', () => App);

In app.json

{
    "name": "gextranet",
    "displayName": "gextranet"
}

In android/settings.graddle

rootProject.name = 'gextranet'

In android/app/src/main/java/net/gextra/app/MainActivity

protected String getMainComponentName() {
    return "gextranet";
}

In android/app/src/main/res/values/strings.xml

gextranet

emacs android/app/build.gradle

...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {

cd android    ./gradlew assembleRelease

ca cree un fichier ici : android/app/build/outputs/apk/app-release.apk

react-native run-android --variant=release

tester manuellement :

adb devices
adb -s [device] install example.apk
adb -s 9885e64d5131533535 install android/app/build/outputs/apk/app-release.apk
