Ionic cordova run android FAILURE


#1

Hi, when I try to start my Ionic App with the
ionic cordova run android
or the
ionic cordova emulate android
the process fails :frowning:

I’ve this output in Console:

FAILURE: Build failed with an exception.

* What went wrong:

[OK] Your app has been deployed.
     Did you know you can live-reload changes from your app with --livereload?

I’ve checked in the specified path and the aapt2.exe doesn’t exist.

How can I resolve this trouble?


My IONIC App doesn't run in an emulated device

Nobody can help me?
:frowning: :frowning: :frowning:


#3

What is your ionic info output?


#4

ionic info:

cli packages: (C:\Users\...\AppData\Roaming\npm\node_modules)

    @ionic/cli-utils  : 1.19.1
    ionic (Ionic CLI) : 3.19.1

global packages:

    cordova (Cordova CLI) : 8.0.0
 

local packages:

    @ionic/app-scripts : 3.1.8
    Cordova Platforms  : android 7.0.0
    Ionic Framework    : ionic-angular 3.9.2

System:

    Node : v7.9.0
    npm  : 4.2.0 
    OS   : Windows 7

Environment Variables:

    ANDROID_HOME : not set

Misc:

    backend : pro

#5

Remove all the icon and splash image inside the ./resources/android (broken image may be). Then generate again by running ionic cordova resources and build it again. Run your command ionic cordova run android afterward.


#6

I’ve removed the images as you told me, I’ve generate images again, then I’ve tried to rebuild project with
ionic cordova build
but I’ve the same error :frowning:


#7

Did you install Android? Try to install Android Studio, open a new Project with it and open the SDK Manager from the toolbar (should be 2nd symbol from right) and install Android 8, Android SDK Build Tools, Android SDK Platform-Tools, Android SDK Tools and Support Repository. Also add the Android SDK Location you find in the SDK Manager to your Path variable:

set ANDROID_HOME=C:\<installation location>\android-sdk-windows
set PATH=%PATH%;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools


#8

I’ve installed Android Studio and the reccomended packages yet, but now I’ll try to uninstall and reinstall them as you have told me.
I’ll let you know as soon as the operation is over :slight_smile:


#9

Now the Android SDK Location is added, in ionic info I have:

ANDROID_HOME : C:\Users…\Android\Sdk

and it’s the right directory!

But the output of ionic cordova run android is:

...
cordova run android
Android Studio project detected

rocess with a non-zero exit code.

[OK] Your app has been deployed.
     Did you know you can live-reload changes from your app with --livereload?

I don’t understand this trouble :sob::sob::sob:


#10

Is it working with ionic serve or do you get the same error?

It seems like many people are getting this error.


#11

Wow! Okay, lets try something else. The project path, if the project path is long, try to change the project location to a direct/short path

For example:
Old path: c:\users\your-user-name\projects-container\folders\project-folder
New path: c:\users\your-user-name\project-folder

If I could remember, I once had a similar issue though mine was as a result of changing my project folder name from upper case to lower case (PRojects -> projects).


#12

ionic serve

Is working correctly, It launch my Browser and run the app :disappointed_relieved:


#13

I get
Subproject Path: CordovaLib
Subproject Path: app
Starting a Gradle Daemon (subsequent builds will be faster)

What do you get with gradle -v ?

You may have to install gradle correctly.


#14

I’ve tried to change the Project location to a shorter one but it doesn’t work.
I’ve also tried to change name of the Project folder with a new name without any uppercase char, but it doesn’t work.


#15

Gradle doesn’t exist, gradle isnt’ a recognized command from my prompt.

I’ve installed the latest gradle (4.4.1) with Chocolatey.

Now I’ve the same output when I’m trying to run the app:

...
cordova run android
Android Studio project detected

[12:27:55]  lint finished in 6.93 s

#16

I would recommend two options.

First check, if gradle -v now works. You may have to add the path:

In File Explorer right-click on the This PC (or Computer) icon,
then click Properties -> Advanced System Settings -> Environmental Variables.

Under System Variables select Path, then click Edit.
Add an entry for C:\<gradle-path>\bin . Click OK to save.

or use set PATH=%PATH%;C:\<gradle-path>\bin and check with echo %path%

Another option is to reinstall android platform for your project by using ionic cordova platform remove android and ionic cordova platform add android


#17

Now gradle -v works and the output is:

------------------------------------------------------------
Gradle 4.4.1

But when I’m trying to remove android platform I’ve this error:

I think it is enough to delete the android folder from platforms in your project by hand.

You could also try to reinstall nodejs. If you get that error in many commands, it may be a problem with node, cordova or the ionic cli


#19

I’ve done it, manually remove folder, remove and install nodejs, but the error persists :frowning:
I can’t add android platform now, so far this command has never given me any kind of problem :confused:


#20

Can you test it with a new ionic project? If it occurs there, too, we know that its a problem with the tools.
