How i can fix this error?

The problem is that your app is targeting 16 API level of Android and you are trying to run it in a lesser API (15). Try changing the API level in the manifest but, I think that the lesser Android API is 16 if you want to run React Native Apps.

According to this page:
Supported target operating systems are >= Android 4.1 (API 16) ...
You are tying to build into a device with API 15. Not going to work.

Add the following method into your build.gradle (before the allprojects method)
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "28.0.0"
}
}
}
}
Change your react native version to 0.57.3 in package.json
And be happy

Can somebody please let me know how to sort this issue? Thank you.
It says Duplicate class copied. How to solve this issue. I tried exclude in build.gradle but it's not helping.

I encountered same issue while building my app and I solved it by
Update android SDK
Remove platform using proper command
ionic cordova platform remove android (if you are using latest CLI)
then add android platform again and build it.
if it still dont work, try downgrading nodejs to previous version and build.

Solved the question.
I needed to do exclude META-INF

So, i don't know what is my error because I have install all application required.
Thanks!

My solution:
This solution solved Android problems, if you need solved iOS
problems, maybe you need learn about ios-sim
# First, Install nodejs
brew install node
# install cordova
sudo npm install -g cordova
# install cordova
sudo npm install -g ionic
sudo npm install -g ionic
# install android sdk: android, adb, etc
brew install android-sdk
# Execute android
android
# after run android you need install
# Tools: Andoird SDK Tools, Android SDK Platform-tools, Android SDK Build-tools
# Android 4.4.2 (API 19)
# Extras: Android Support Library
# install ant
brew install ant
Then, after install all dependencies, you can create a new ionic project
like to
ionic start <YouAppNameHere> blank
Then you need add android platform support with
ionic platform add android
And finally, you can build and emulate you project for android devices with
ionic build android
or
ionic emulate android
You can move/copy you old www folder data to you new www folder, and
the old plugins can be installed manually using ionic plugin add <YouPluginNameHere>

ionic build android :CordovaLib:compileDebugJavaWithJavac

I am unable to figure this out, I have tried installing SDK tools in my SDK manager for versions 20 through 24. I keep getting this error when I run
ionic build android
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':CordovaLib:compileDebugJavaWithJavac'.
Compilation failed; see the compiler error output for details.
Most articles I have seen with this error points to updating SDK tools which is not helping me.

How to disable gradle in cordova?

I Upgraded my cordova from 4.3 to 5.0.0 few days ago.
After that I'm facing with various errors and build fails!
Every time I want to build my app, I have to follow this long instruction to get successful build:
cordova platform remove android
cordova platform add android
exit and reopen node.js command prompt as administrator
cordova build android
I want to pull out my hairs!
I think problem is from gradle. Is there any way to disable gradle in Cordova?

You can force CLI to use Ant during a build with the following command:
cordova build android -- --ant

I had the same problem. My solution was to run cordova clean.
