This is my first time writing an ionic 2 app. I have cloned from github a tutorial app and successfully built it on my local pc.
$ npm install
$ ionic platform add android
$ ionic build android
This command works $ ionic serve --livereload (I can run my app in the browser, set breakpoint and debug in visual studio code. Everything works perfectly)
But when I attempt to deploy the app on my android emulator
(target:Android 7.0, cpu/abi: Intel Atom (x86_64), Ram 2048, VN Heap:64), this app craches.
This is the command to deploy app to emulator:
$ ionic run android
And this is the crach:
I have looked at many threads over the internet. Some suggest to reinstall every thing. (But ionic server works perfectly...). Here are my system specifications:
npm:
ionic 2:
Please any help would be greatly appreciated
I also had the same problem with ionic when running on emulator.
I solved it by making sure that the value for FadeSplashScreenDuration and SplashScreenDelay are set as Integers, instead of doubles in the config.xml file under your ionic project folder.
It might be not the solution you were looking for but lately I had the same problem and couldn't found the solution.
My target on emulator had android 7.0 version (API 24).
It started to working when i created new device with android 6 (API 24).

This question is related to ionic 3 and I want to know how to run an ionic app using a real device.
I have developed an hybrid application and I was not able to connect my app with server. It works fine in my laptop browser. But it does not work in devApp and android apk.
I have tried many solutions but was not able to get the perfect solution. I have made a proxy server to access the api by ionic devApp but it doesn't even show a single error.
I think this problem is related about CORS.
Use the additional parameter of --devapp when running your ionic serve.
ionic serve --devapp
Should work now.
For me allowing port 8100 in my firewall was needed. Then everythig works.
CORS is not a problem when you build your app on a real device.
To run your app on android device :
ionic cordova platform add android
ionic cordova build android
ionic cordova run android (Connect your device before executing this)
Try Reinstalling cordova-plugin-whitelist plugin.
I'd the same problem. But I just uninstalled and installed again the ionic DevApp and it solved it.
Try using the command ionic serve -c this for view the app into Ionic devApp
I am not sure if this helps now - In your DevAPp you have settings where you can manually enter IP address and port. This will be the private IP (192.x.x.x) and 8100 that is displayed when you start the ionic serve --devapp from the terminal.
On this website (https://ionicframework.com/docs/intro/deploying/) I read that I should give this command on the command prompt: ionic cordova run android --prod --release
I tried it but it only tried to start the app on an emulator (I have some problems with it, so it didn't actually start the emulator). Does this command also create a file I can put on my mobile and install the app? I don't want to put the app on Google play, just on my mobile.
I tried putting the android-debug.apk on my mobile and running it but my mobile couldn't install it (.../platforms/android/build/outputs/apk/android-debug.apk)
I'm not trying to test the app on my mobile, I'm trying to install it.
If you want to deploy the apk to your device
ionic cordova run android --device is indeed correct. (try adding --device)
You only need --prod --release when building for production (longer buildtime).
Before running (= building, installing and starting your app) check if your device has USB-debugging enabled. You can check if your device is connected by running adb devices. Since the run command includes building, yes run should create a apk for you.
As you said you also could install the apk manually. Here make sure to use the correct apk. android-debug.apk is the development build (no --release tag) and since your trying to run a production one (--release) you are looking for android-release.apk or android-release-unsigned.apk.
go to settings -> security in your phone then check Unknown sources (Allow installation of apps from sources other than the play store) and try to put the android-debug.apk again. this should work
my ionic project works fine with ionic serve --lab ,but while copied the.apk file in build folder to my phone and install the app but blank screen appears ,
Please can anyone suggest what might be my problem
my app is using google maps,key is provieded for both app and browser in index.html
Have you tried running it in the emulator ? Since its much easier to see the error logs . Try ionic emulate android -l or ios -l (whichever OS you are building for) and then once the execution starts run the command consolelogs it will log all the activity and you will have a better understanding about why its not working.
+1 for using Chrome Remote Debugging feature. It give you the same output as you would receive from running you app in the browser.
Additionally, I have found that sometimes if your app is already compiled, the ionic CLI doesnt always copy your current files into the APK, and uses the older cached files instead. If you are banging your head against the wall, run the following commands to make sure you have your latest code in your APK.
ionic platform remove android
ionic platform add android
ionic run android
I suggest you use the Chrome Remote Debugging feature. I encountered the same, and looked for answers to my symptom for hours. Once I connected to the chrome remote debugger, I got the console.log back, and noticed there was a problem in my routing setup.
It was a problem with ionic CLI. I've updated it to the latest and reinstalled all dependencies.
i am facing this error when i want to run ionic build android command.
i tried everything and obviously i have no idea what to do here .
i have SDK and JDK , Gradle and other things .
if i run the ionic serve command it works with no problem and the app shown in the browser but i can't build the app with build command .
i installed the cordova and ionic using this tutorial http://learn.ionicframework.com/videos/windows-android/ and i think i dont miss anything around here .
when i run android command , it shown up the android sdk manager with the API installed , when i run gradle it works . but this one does not work
here is the picture of the error :
This happens to me with ios builds and re-installing the platform will always worked for me. try that
ionic platform remove android
ionic platform add android
read here on almost the same thing (but with ios)
HTH
I am totally new to Cordova, but now I have installed Cordova with NPM and installed Android SDK and set up an AVD which seems to work perfectly, until I want to emulate my project. Where the actual app for some reason is not loaded into the emulator.
The following action is done:
marvin:HelloWorld$ cordova -d emulate android
cordova library for "android" already exists. No need to download. Continuing.
Wrote out Android application name to "HelloWorld"
Wrote out Android package name to "com.example.hello"
Calling plugman.prepare for platform "android"
Preparing android project...
Processing configuration changes for plugins.
Iterating over installed plugins: []
Writing out cordova_plugins.js...
Running on emulator for platform "android" via command ""/home/marvin/Development/projects/HelloWorld/platforms/android/cordova/run" --emulator" (output to follow)...
Then it start Android emulator up, but the app is not there. Does anybody have a suggestion to fix this issue, so I am capable of actually testing in my emulator?
Thank you in advance.
I just had the same problem, and I was missing PATH to platform-tools in android sdk folder, after I added it everything was in place.
I had the same problem as well; I could run the cordova emulate android command just fine, and the emulator would eventually start up and function, however, the test app was never installed on the device. I was not getting any errors from the Cordova CLI or the console or anything.
I found that there is a bug report about this issue here: https://issues.apache.org/jira/browse/CB-4285
Two solutions have been found for this issue:
1. Make sure you are using an Oracle JDK and not an IBM JDK, and
2. Make sure the AVD that emulate starts up has a min-target-sdk set to API 10 (Android 2.3.3) or higher. (This was my problem.)
Sometimes it works deleting the previously installed version of the app in the emulator. For this you could also launch it with the option "Wipe user data" checked.
Just for the record, none of the other solutions worked for me.
I had the same issue. Following solved it for me.
Make sure that API level of your AVD is greater than minSdkVersion specified in config.xml specified in your cordova app.
If anyone still having this issue:
I had a same problem with device being offline.
if ddms is running it looks after connected devices.
adb kill server
and than run ddms
Also make sure your app id doesn't begin with a number or any other character like "_". For example, if your app id is com.4company.MyApp or com._company.MyApp it just won't load on the emulator. The first one is because Java doesn't allow names beginning with a number, and the second one I guess it's a Cordova thing.
You should also use adb logcat to show the emulator errors on the command line.
For me, the app was not starting up because I had a second emulator running in the background. Uninstalling bluestacks (android emulator for windows) fixed the issue in my case. Running "adb logcat" should tell you if you have multiple emulators running.
I just had the same problem, and It was my emulator device that was with the API 15. Just updated to API 17 and the problem solved.
