Facing an error when running my android app on an emulator

Hi I'm just starting to learn how to code on android studio.
After running npm run android on my terminal, I've faced some errors which I could not solve.
The error message is as follows :

I hope you guys can help me with it.

I managed to fix this issue by adding a line google() to ~/my-app/android/build.gradle in the following section:
allprojects {
respositories{
google() //right here
}
}
Just a guess, but I believe it is a regression to do with the new Android Studio 3.2.0 release.

This is in react native which in fact i never used, this isn't an answer but i cant comment as my reputation is too low for that(pardon me). Have you installed android build tools? The ':app:_internal_aapt2_binary' is a configuration file that the system needs to compile the application which is a part of build tools.
If you are using android studio 3.0, then in gradle , change the dependency from
compile files('xyz')
to
implementation files('xyz')

react-native run-android => Could not resolve all dependencies for configuration ':classpath'

I insert java_home in environment correctly and test it in cmd. I am connecting to the internet with the proxy and can download react-native packages. adb devices run correctly on cmd, but when running "react-native run-android" command I give below error:

Make sure you have an Android emulator running or a device connected and
have
set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html
Even I add Google() to build.gradle in allprojects{} It doesn't work again. and still giving that error.
By the way, I am using JDK version 9 and gradle version 2.3.3

Unfortunately, Jcenter blocks requests from Iran due to US sanctions. You can use Hotspot Shield to connect to Jcenter, other VPN's providers may not work correctly.
and i suggest you to update your gradle by this changes:
1- change gradle version to classpath 'com.android.tools.build:gradle:3.1.1' in android/build.gradle
2- change distributionUrl from android/gradle/wrapper/gradle-wrapper.properties to distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
3- add repository to android/build.gradle like this:
repositories {
mavenLocal()
google()
jcenter()
maven { url "https://jitpack.io" }
maven { url 'https://maven.google.com' }
}
4- start Hotspot Shield and build project.
I hope this may help you.

It was already mentioned in this question, Android obsolete library Android Support Library is no longer available.
Using jfxmobile plugin version 1.3.1 solves the issue, as it uses the multidex library that should be found here: ANDROID_HOME/extras/android/m2repository/com/android/support/multidex/1.0.1/multidex-1.0.1.aar.
Note you need to install with the Android SDK Manager both Extras/Google Repository and Extras/Android Support Repository.
Also is advisable to create a properties file with the ANDROID_HOME variable, under /Users/<user>/.gradle/gradle.properties:
ANDROID_HOME=/Users/yotti/Library/Android/sdk
and remove the line in the build.gradle -> jfxmobile -> android -> androidSdk.
As for the Charm dependencies you are using the wrong repository, you need:
repositories {
jcenter()
maven {
url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
}
}
Finally, you don't show a ControlsFX dependency, so it is not possible to have the exception posted in the first place.

React Native: Could not resolve all dependencies for configuration

How can i resolve this problem? I've read many articles here, Local Maven repository for Support Library has been installed in my computer.
Thanks very much!

I just solve this problem this morning.
If you noticed there is a list of dependencies map defined in settings.gradle inside android folder.
Here is what I did:
Go to android folder
Run this command ./gradlew installDebug --info
And then it will show a list of dependencies that android need. It also show which dependencies are not resolved.
In my case I'm lack of 'react-native-network-info' so all I need to do is npm install that package.
Maybe your situation will difference but I think this can help you.

In react-native this problem is due to flipper dependencies, it is solved by increasing its version to 0.105.0. (file: gradle.properties)

The following error occurs when trying to build an android app with cordova and the cordova-crosswalk plugin:

Please notice that section:
Could not resolve all dependencies for configuration ':_armv7DebugCompile'.
It can happen because building an android project with the crosswalk plugin try to build two apks : one for ARM, the other for x86.
The solution is to install Android Support Repository :
Open the SDK manager (from command line, type android).
Under Extras, Make sure you have Android Support Repository and Google Repository downloaded.

Update answer
Seems starting from crosswalk 16, Android Support Repository and Google Repository is not enough.
You need to install Local Maven repository for Support Libraries from Extras as well.

for me Solution was:
i updated crosswalk to #15.44.384.13
ionic browser add crosswalk#15.44.384.13
then i changed config.xml:
<preference name="xwalkVersion" value="15+" />
cuz versions "16+" - "18+" not work for me

It may be the problem when you did not include google support respository and android support repository under extras. as well as when you not update the cordova with your cordova platform.because cordova and cordova platform must be use latest version.update your Cordova with npm update cordova -g --save and cordova platform with cordova platform update platform_name(like android).

This worked for me
1.goto platforms\android\cordova-plugin-crosswalk-webview folder
2.Open .gradle file
3.find
dependencies { compile xwalkSpec }
and replace with
dependencies {
compile 'org.xwalk:xwalk_core_library:22.52.561.4'
}
**
note: 22.52.561.4 is version of crasswalk on your machine
to know it , open ionic app , chrome://inspect then
window.navigator.userAgent
This will print some lines , copy xwalk details from there

I know it's a little late to add an answer. but I faced this issue for a long time and none of these steps fixed it. If your IP is from Iran, then you should build your project with VPN on. It seems that dependencies are banned for some countries.
