What devices?
What Android versions exactly?
Also post your ionic info output please.

Did you remote debug the problem on the device already? Follow these instructions here to debug the problem in Chrome dev tools: https://ionic.zone/debug/remote-debug-your-app#android Look at the console and network tabs for errors.

Your choice but you can share your repo with me and I’ll take a quick look


#5

Your CLI is so old it doesn’t contain important information. Run ionic platform list to get this information please. (Or upgrade your CLI and run ionic info again)

ionic platform list

As this is an old error, you might want to search the forum for older solutions or workarounds

This might be better if it is upgraded as well, 6.2.3 or even 6.3.0.

@Sujan12 if i update android platform to 6.3.0 then below error occur

Error: Could not find an installed version of Gradle either in Android Studio,
or on your system to install the gradle wrapper. Please include gradle
in your path, or install Android Studio


#10

Pretty clear error message.

Make ionic cordova requirements happy basically.


#11

Install Android Studio to fix this issue. Or install Gradle manually and ad the Gradle path to your environment variables.


#12

@Sujan12 i have already include gradle and install Android Studio if i am downgrade my android platform to 6.3 to 6.1 then these error goes and work


#13

Yes of course, because your local installation is correct for 6.1. - but not for 6.3.

With cordova-android 6.3 ionic cordova requirements doesn’t output any errors for you?


#14

you were able to solve this problem … I’m having the same problem as you


#15

I ran your line of code and I throw myself the following

Java JDK: installed 1.8.0
Android SDK: installed true
Android target: installed android-28,android-27,android-26,android-23,android-22
Gradle: installed /usr/local/Cellar/gradle/4.8.1/bin/gradle

But the app does not work for me in Android 5.0 … I have no idea that it could be
