I know there are documents on this, but I have no clue how to get the app to actually show up on the phone. All I get after running is a Node.js window on my PC instead of phone.
I am using Expo for this purpose. There is a link to it https://expo.io/
It's pretty easy to set up and use.
When you run it from, for example, Visual Studio Code you can run it on your real device, just installing Expo app from AppStore/GooglePlay (Scan the QR code) as well as on PC in Android Studio etc.
Use expo
Expo enables you to run your react-native app on your local android or iOS simulator as well as physical devices.
In the past, the android simulator was painfully slow and I use the device only to debug the android applications.
What's the preferred development environment, simulator, or device for React native application?
Actually, emulator can be super fast given the fact that you can configure them as you want (Giving as many RAM as your computer has).
My job is to do mobile app with RN and I almost only user the emulator. For the feature that does not work on it (Opening file with app proposition, for example), I'm using a device.
I also stopped using the debug mode for Android because it is so slow! If you want to look at the console.log, you can open a terminal at the root of your project and run react-native log-android. It will allow to see the log without being force into debugging
TypeError inside of index.android.bundle
I have this error when running my React native on my physical android device but everything works perfectly on any android emulator i've tried. I don't really know what can I do since this error is in the bundle so i'm at a loss at where to really fix this error.
I'v build a simple blank Firemonkey application in XE7.
This app runs on an Nexus7 (Android).
Now I want to run this app on a BlackBerry OS10.
I have a BlackBerry Simulator on my pc.
I can run the .apk on the simulator. After the installation I can run the app.
Afther the default splashscreen of the firemonkeylogo, I get a message 'App has stopped'. Then the app stop.
I get also this error on a BlackBerry Z10.
Can someone help me to look in the right direction?
Solved:
With the last updates of Blackberry I can run the apk on a blackberry device.
I'm working on Titanium with alloy framework and quit new in it. I have develop some simple apps and these are working fine on my laptop's browser.Now i want to test it on my android mobile but unable to deploy it on my device. I've installed device driver on system and connected device on debugging mode but when i try to run as android device in titanium , i get Invalid "--android-sdk" value "C:\android-sdk-win" error. while ni case of native android apps (with java/eclipse) my device is working fine and I'm able to test my apps on my mobile in debugging mode. Don't know what is the problem with Titanium. I've searched internet for this problem but couldn't find any good solution. Any help will be highly appreciated.
I guess you don't have any SDK in "C:\android-sdk-win".
You should ensure you have the correct Android SDK/NDK paths configured in Titanium:Preferences:Studio:Platforms:Android.
