i am also getting this exact same issue with this exact same step by step. i would LOVE to know why this is happening for release builds but not debug builds.

For me this works:
add this code in _/android/build.gradle_

subprojects {
  project.configurations.all {
      afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 26
                buildToolsVersion '26.0.2'
            }
        }
    }
     resolutionStrategy.eachDependency { details ->
        if (details.requested.group == 'com.android.support'
              && !details.requested.name.contains('multidex') ) {
           details.useVersion "26.0.2"
        }
     }
  }
}

26.0.2 is the vs that I've seted in _/android/app/build.gradle_ file for buildToolsVersion.
Give a shoot.

@rodrigofbm, you workaround not works for me =/

* Where:
Build file '/home/felipe/Projects/personal/grioty/android/build.gradle' line: 33

* What went wrong:
A problem occurred configuring project ':app'.
> Android tasks have already been created.
  This happens when calling android.applicationVariants,
  android.libraryVariants or android.testVariants.
  Once these methods are called, it is not possible to
  continue configuring the model.

Can you explain what this code are doing? Perhaps I can understand what is happening with my project.
Thanks!

@FSPinho try only this:

subprojects {
  project.configurations.all {
      afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 26
                buildToolsVersion '26.0.2'
            }
        }
    }
  }
}

Thanks!
But the errors are occurring exactly due to this two lines.
compileSdkVersion 26
buildToolsVersion '26.0.2'

Can you send me information about the development environment?
With the terminal open in the project folder: react-native info

Environment:
  OS: macOS High Sierra 10.13.4
  Node: 6.11.3
  Yarn: Not Found
  npm: 6.0.1
  Watchman: 4.9.0
  Xcode: Xcode 9.3.1 Build version 9E501
  Android Studio: 3.0 AI-171.4443003

Packages: (wanted => installed)
  react: 16.0.0 => 16.0.0
  react-native: ^0.55.4 => 0.55.4

for my case, I uses below
Gradle v4.4
classpath 'com.android.tools.build:gradle:3.1.1'
classpath 'com.google.gms:google-services:3.2.0'

compileSdkVersion = 27
buildToolsVersion = '27.0.3'

So you have to change the code for:

subprojects {
  project.configurations.all {
      afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 27
                buildToolsVersion '27.0.3'
            }
        }
    }
  }
}

About that, I had tried it. still the same error result.

For Gradle v4.4.
the minimum compile version seems to be 27.0.3 or 27.1.0 either one.

It just like something linking to this problem after I install react-native-camera latest version. Forced to update to newer version in order to compile. And here it is, this problem show up.

@kkusanagi I have the same problem after installing react-native-camera v1.1.4. Did you solve it?

hi, @pkhien95 . This is how it work for me now by using react-native-camera v0.10.0.
About newest version, sorry, still got problem.

Environment:
OS: macOS High Sierra 10.13.4
Node: 6.11.3
Yarn: Not Found
npm: 6.0.1
Watchman: 4.9.0
Xcode: Xcode 9.3.1 Build version 9E501
Android Studio: 3.0 AI-171.4443003

Packages: (wanted => installed)
react: 16.0.0 => 16.0.0
react-native: ^0.51.1 => 0.51.1
react-native-camera: 0.10.0

In android android/gradle/wrapper/gradle-wrapper.properties change this
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

Add below in android/gradle.properties to SOLVE this thread problem TEMPORARILY workaround. Need remove in future before year 2019.
android.enableAapt2=false

Then you may meet another error as duplicate file for drawable-* png file.
As to solve this, goto android/app/src/main/res folder and delete all drawable- folder only left mipmap-* and values. Also temporarily, please back up deleted folder for IN CASE.

in android/build.gradle, setting like below.

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        mavenCentral()
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:3.1.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 27     //do this in android/app/build.gradle too
                buildToolsVersion '27.0.3'  //do this in android/app/build.gradle too
            }
        }
    }
}

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        //maven {
        //    url 'https://maven.google.com'
        //}
        google()
    }
}

@kkusanagi Thanks. This is my solution for the latest version of react-native-camera (1.1.4):

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "27.1.1"
            }
        }
    }
    afterEvaluate {
        android {
            compileSdkVersion 27
            buildToolsVersion "27.0.3"

            defaultConfig {
                targetSdkVersion 27
            }
        }
    }
}

In my case, none of the above worked, nor was necessary.....

aapt in build tools 23 is a 32bit binary... I'm on a 64 bit system. I didn't have correct 32 bit libs installed so it didn't run.

Installing libncurses5:i386, libstdc++6:i386 and zlib1g:i386 fixed it.

@pkhien95 Your solution works for me, thank you for saving my day.

in android/gradle.properties, setting like below.
android.enableAapt2=false

@Scimanyd your solution work for me . thank for that

@Scimanyd Thanks bro, your solution worked, but what exactly does it do though.

@matt-goingout you are genious, vlws!!! nince

@matt-goingout

In my case, none of the above worked, nor was necessary.....

aapt in build tools 23 is a 32bit binary... I'm on a 64 bit system. I didn't have correct 32 bit libs installed so it didn't run.

Installing libncurses5:i386, libstdc++6:i386 and zlib1g:i386 fixed it.

where and how to install these libraries?

@viv3kk just run sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386 in ubuntu

@Scimanyd I feel like it's worth noting that

WARNING: The option 'android.enableAapt2' is deprecated and should not be used anymore.
Use 'android.enableAapt2=true' to remove this warning.
It will be removed at the end of 2018.

It seems that this will not be a viable option in the long run.

"apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386 in ubuntu"

How about MacOS? how to install it?

@pkhien95
i'm also run into the same error, tried your solution, and got this error:

Execution failed for task ':app:preReleaseBuild'.
> Android dependency 'com.android.support:support-v4' has different version for the compile (27.1.0) and runtime (27.1.1) classpath. You should manually set the same version via DependencyResolution

How does your android/build.gradle and android/app/build.gradle looks like?

Hey, guys.

I've also got the same issue after upgrade from RN 0.55 to 0.56, then I added this to my android/build.gradle, and it helped me to generate .apk, but this .apk doesn't work! It just shows the launch screen and then stops...
Does anyone has an idea?

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "27.1.1"
            }
        }
    }
    afterEvaluate {
        android {
            compileSdkVersion 27
            buildToolsVersion "27.0.3"

            defaultConfig {
                targetSdkVersion 27
            }
        }
    }
}

For those who are doing this before generating apk

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

it generate unnecessary drawable images in drawable folder. so make sure to remove it and try again.

android-> app -> src -> main -> res -> drawable

After trying all the above solutions, facing the same issue. A bit digging into the matter and the workaround to build release apk is:
Delete your android dir in your root folder.

react-native upgrade to build the android dir again

Now generate the release apk by command line

I have the same issue after moving to react-native 0.57

android.enableAapt2=false didn't help me.

Same problem, can't solve it: https://github.com/rebeccahughes/react-native-device-info/issues/365#issuecomment-425609406

My solution that helps me with 0.57 react-native

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion rootProject.ext.compileSdkVersion
                buildToolsVersion rootProject.ext.buildToolsVersion
            }
        }
    }
}

Solve here:

https://github.com/rebeccahughes/react-native-device-info/issues/365#issuecomment-425609406

So you have to change the code for:

subprojects {
  project.configurations.all {
      afterEvaluate {project ->

            }
        }
    }
  }
}

Worked for me! Thanks My bro

@rodrigofbm thanks dude it worked for me

@antonsivogrivov thanks it worked for me

So you have to change the code for:

this worked for me. version 0.57

My solution that helps me with 0.57 react-native

subprojects {

        }
    }
}

this worked for me. version 0.57 👍

@kkusanagi Thanks. This is my solution for the latest version of react-native-camera (1.1.4):

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "27.1.1"

在转向react-native 0.57之后，我遇到了同样的问题

android.enableAapt2 = false没有帮助我。

解决了吗？

I had the same issue, @rodrigofbm 's solution worked for me.
Just add the following at the end of _../android/build.gradle_ file

subprojects {
  project.configurations.all {
      afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 26

            }
        }
    }
}

I have the same problem, but i have no idea，did you solved it?

So you have to change the code for:

subprojects {
  project.configurations.all {
      afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {

                buildToolsVersion '27.0.3'
            }
        }
    }
  }
}

work for me like a boss! thank for saving time

@antonsivogrivov where should i add this:
subprojects {
project.configurations.all {
afterEvaluate {project ->
if (project.hasProperty("android")) {
android {
compileSdkVersion 27
buildToolsVersion '27.0.3'
}
}
}
}
}

@vivek-walecha-657 in <ROOT>/android/build.gradle

if you are on 0.57 ++ I would recommend using @antonsivogrivov solution. as it has the variables defined from RN.

Hello there 👋 this issue has been reported for an old version of React Native. Ideally, we'd like everyone to be using 0.59 (see the awesome changes it brought) but we know updating can be a pain. During 0.59 update, some changes were made to the android build system, things like compileSdkVersion and others have been updated. I'll close the issue now.

But please, if it's actually still an issue with 0.59 please comment below and we can reopen it. Even better, please send us a pull request with a fix 😊

"react-native-appodeal": "^2.1.5",

This is still happening and has an issue linked here that is open: https://github.com/facebook/react-native/issues/22234

FWIW, having this bit in <root>/android/build.gradle:

subprojects { project -> 
  afterEvaluate {
        if((project.plugins.hasPlugin('android') || project.plugins.hasPlugin('android-library'))) {
            android {
                compileSdkVersion rootProject.ext.compileSdkVersion
                buildToolsVersion rootProject.ext.buildToolsVersion
            }
        }
    }
}

and this bit in <root>/android/app/build.gradle:

subprojects {
    project.configurations.all {
        afterEvaluate {project ->
            if (project.hasProperty("android")) {
                android {
                    compileSdkVersion rootProject.ext.compileSdkVersion
                    buildToolsVersion rootProject.ext.buildToolsVersion
                }
            }
        }
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion rootProject.ext.buildToolsVersion
            }
        }
    }
}

is what did the trick.

I have resolved my issue with this command ./gradlew app:assembleRelease

if you want to build just debug apk for offline then try this command
./gradlew

simple you have no need to do any this

FWIW, having this bit in <root>/android/build.gradle:

subprojects { project ->

        if((project.plugins.hasPlugin('android') || project.plugins.hasPlugin('android-library'))) {

            }
        }
    }
}

This worked for me as well [email protected]

For me this works:
add this code in _/android/build.gradle_

subprojects {
  project.configurations.all {
      afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 26
                buildToolsVersion '26.0.2'
            }
        }
    }
     resolutionStrategy.eachDependency { details ->
        if (details.requested.group == 'com.android.support'
              && !details.requested.name.contains('multidex') ) {
           details.useVersion "26.0.2"
        }
     }
  }
}

26.0.2 is the vs that I've seted in _/android/app/build.gradle_ file for buildToolsVersion.
Give a shoot.

working for me

@fossage where to place the bit inside the files?
<root>/android/build.gradle
<root>/android/app/build.gradle
can you paste a sample, thx

/android/build.gradle
a bellow of the code

FWIW, having this bit in <root>/android/build.gradle:

subprojects { project -> 
  afterEvaluate {
        if((project.plugins.hasPlugin('android') || project.plugins.hasPlugin('android-library'))) {
            android {
                compileSdkVersion rootProject.ext.compileSdkVersion
                buildToolsVersion rootProject.ext.buildToolsVersion
            }
        }
    }
}

and this bit in <root>/android/app/build.gradle:

subprojects {
    project.configurations.all {
        afterEvaluate {project ->
            if (project.hasProperty("android")) {
                android {
                    compileSdkVersion rootProject.ext.compileSdkVersion
                    buildToolsVersion rootProject.ext.buildToolsVersion
                }
            }
        }
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'

                details.useVersion rootProject.ext.buildToolsVersion
            }
        }
    }
}

is what did the trick.

thanks a lot it worked now with 0.59.1, i was struggling from last 3 days sometime i hate react native i thought to move native development but people like you always change my mind :-)

Nothing works for me on react native 0.59.0

In my case, i removed the resolutionStrategy block what I was using...

My android/build.gradle are like this:

buildscript {
    subprojects { project -> 
    afterEvaluate {
            if((project.plugins.hasPlugin('android') || project.plugins.hasPlugin('android-library'))) {
                android {
                    compileSdkVersion rootProject.ext.compileSdkVersion
                    buildToolsVersion rootProject.ext.buildToolsVersion
                }
            }
        }
    }

ext {
    buildToolsVersion = "28.0.3"
    minSdkVersion = 16
    compileSdkVersion = 28
    targetSdkVersion = 27
    supportLibVersion = "28.0.0"
}
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
    }
}


wrapper {
    gradleVersion = '4.4'
    distributionUrl = distributionUrl.replace("bin", "all")
}

    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            // For each separate APK per architecture, set a unique version code as described here:

            def versionCodes = ["armeabi-v7a":1, "x86":2]
            def abi = output.getFilter(OutputFile.ABI)
            if (abi != null) {  // null for the universal-debug, universal-release variants
                output.versionCodeOverride =
                        versionCodes.get(abi) * 1048576 + defaultConfig.versionCode

./gradlew app:assembleRelease

Suffering from this with RN 0.61.2.

Fixed with this after react-native bundle:

git clean -df android/app/src/main/res/

I have resolved my issue with this command ./gradlew app:assembleRelease

This definitely worked for me. Thanks

in android/gradle.properties, setting like below.
android.enableAapt2=false

Thanks so much, very helpful for me!

./gradlew app:assembleRelease

finally something worked.
I have been trying to create build from last 24 hours, but nothing was working until i found this.
Thanks mate

I have the same problem after using react-native-ble-manager(6.5.1).
@kkusanagi Thanks. The following is my solution.

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")){
            android {
                compileSdkVersion 28
                buildToolsVersion '28.0.3'
            }
        }
    }
}

I was stuck in this for the last three days. finally, I was able to solve.
This was because of the duplicate resources generated in your \yourProject\android\app\src\main\res\
Just check here that some unwanted files will be created. delete some of the images in that folder are not required. and delete the raw folder in this folder. it works

Thanks

./gradlew app:assembleRelease

ty bro I have solved this problem
