React-native: Double tapping R after making a change in index.android.js doesn't reload the app.

[vijaybritto]

Description

Installed react native for android as per official docs. Ran the app. It loads in the emulator. But whenever I make a change in index.android.js and press R twice, it doesn't reload the app as mentioned.

Additional Information

• React Native version: 0.42.0
• Platform: Android
• Operating System: OSX 10.11.6
• Dev tools: Android studio

Figured it out.
cmd + M open the developer options. It has the option for hot reloading. Enabling that works.
It has to be mentioned in the docs.

You don't need to turn on hot reloading for refresh to work.

Still doesn't work for me. Enabled live reload in the developer options (Ctrl+M) and tried changing index.android.js.

Hot reload works though...

found out that for android you need to enable keyboard in config.ini:

hw.keyboard=yes

[llaine]

@darthbinamira which config.ini ?

[darthbinamira]

in ubuntu it is in ${HOME}/.android/avd/<avd name>/config.ini

This didn't solve the problem actually.

Hola, en mi caso uso Ubuntu pero corro la app en un dispositivo real, y no se actualiza agitando el dispositivo que hago?

Gracias

@3jFernando agita tu dispositivo hasta que aparezca el popup del menú y luego presiona "Enable Hot Reloading". Ahora cuando hagas los cambios en tu archivo ya se podrá ver en tu dispositivo.
