general question:
i have an app i'm developing that uses rhino to execute java script code.
when i run it on my emulator it works well but when i install it on my device it crushes and gives a Use *#9900# to take log message.
i am not sure what that error really means.
i have gone over the code and cleared all log and system out commands and added debug=false on the android manifest.
do i need to install on my device any other software,such as an interpreter so it could run java script?

Every time if I want to run RN project I want to start an android studio and start the emulator manually and then go to the terminal and run the RN. if i run the project without starting an emulator it's giving me an error.
error I got when I run the project without starting an emulaotr
from my experience this is expected behavior. On Mac, running an iOS project is able to open the built in emulator, but never on Android. The error is just letting you know there are no devices running.
One helpful thing you can do is create a shortcut or terminal command to open your emulator without opening Android Studio, which is kind of a pain to open just to start an emulator. You can do this using something like what is mentioned here: https://stackoverflow.com/a/33487044/3218158
I have a problem with the game crashing after the build. If I run the game in Unity, then everything works. And when I build it on android, when I start the first training scenes work fine, but when I reach the main stage, the game crashes. There is a error in Unity:
Google.JarResolver.ResolutionException: Cannot find candidate artifact for com.google.android.gms:play-services-games:8.4+
Maybe that's the problem. If that's not the problem, how do you know what it is?
So this looks like plugin resolve problem. But more information wouldnt be bad and you should learn how to see your device logs on Android. Here is how:
You should check the logs of your mobile device in the moment of the crash. You can do it by using "adb logcat".
First you should download SDK Platform Tools.
Then, enable USB debugging on your phone.
Connect your phone to your PC and give the permission it needs. It will ask you when you first connect it.
Open command line on your computer, go to your SDK Platform Tools folder, copy the directory and paste it after writing "cd " to your command line
Now you can use adb to figure out your Android crashes. To filter the ADB you can use
adb logcat -s Unity ActivityManager PackageManager dalvikvm DEBUG
This way you will only see Unity related logs from your device.
Im trying to generate an APK to test my android build, it used to work before, i dont know what went wrong that it stopped working, whenever i try to run on device either on android studio or my own device, it does not build even though its error clean. App actually installs, but when its about to run it closes down and this message appears
Heres what i got from checking the logcat on Android Studio: https://imgur.com/a/FdE4WMo
Try uninstalling the app from the device and then run it again.
The dev / debug build uses an encryption key that's specific to the machine so I think that maybe you are trying to install a different app over the original one?
i want to preview my nativescript code on an android emulator which as i use the command line which is, i navigated to my app folder which which was successfully but when i type "tns preview" to run an android emulator to see my code in action i get
Found peer TypeScript 3.1.6

# Fatal

#
TypeScript compiler failed with exit code 3221225477
and an android emulator is connected successfully, even nativescript notice the emulator, please what do i do
i have tried the Nativescript sidekick to start the emulator but the nativescript sees the android emulator and it did not report an error indication but when i select the android emulator and click "Run on Device" i get
Build failed. TypeScript compiler failed with exit code 3221225477
even i have tried using my android device for previewing it which i install the nativescript playground & nativescript preview but if i scan the QR Code it is not previewing, please help out
please i need a solution
Preview is to be used with real device for quick testing. The basic idea is to avoid setting up whole iOS / Android SDKs on your local machine.
Produces a QR code which can be used to preview the app on a device without the need to install various SDKs and tools or configure your environment for local iOS or Android development.
To scan the QR code and deploy your app on a device, you need to have
the NativeScript Playground app:
App Store (iOS):
https://itunes.apple.com/us/app/nativescript-playground/id1263543946?mt=8&ls=1
Google Play (Android):
https://play.google.com/store/apps/details?id=org.nativescript.play
If you want to view your app on your android emulator, run the command
'tns run android --emulator'
This is assuming you already have an emulator set up on your machine.
To see a list of your available devices run the command
'tns device'
If you have not set up an emulator follow setup here: https://docs.nativescript.org/tooling/android-virtual-devices
I've created a Test project in eclipse to run some tests for one of my android library. I can run it without problems in eclipse on my device. Is it possible to run these tests on other devices without having them connected to eclipse? I want to send the test project apk to other people so they can run the tests on their device.
I think I'd need something like a test runner app that runs the test and displays the result on the device itself. Does anyone know such an app?
Thanks
Is it possible to run these tests on other devices
without having them connected to eclipse?
yes it is!!
just send the tested .apk file to their mobile, install and use app.
no need any test runner app for this, i have checked it.
