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

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

@FSPinho try only this:

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

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
            }
        }
    }
}

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.

@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
            }
        }
    }
}

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'
            }
        }
    }
  }
}

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.

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.

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.

This worked for me as well react-native@0.59.9

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.

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
            }
        }
    }
}

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.

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？

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

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
            }
        }
    }
}

this worked for me. version 0.57 👍

@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.

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
            }
        }
    }
}

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'
            }
        }
    }
  }
}

Worked for me! Thanks My bro

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

How about MacOS? how to install it?

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

where and how to install these libraries?

./gradlew app:assembleRelease

Here is my Gist with my sample project bulid.gradle , package.json using react native 55.4

https://gist.github.com/Abhishekgarg727/daf031fb9f94fdfd985e84db57dedbe1

@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.

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

Suffering from this with RN 0.61.2.

Fixed with this after react-native bundle:

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

and i have same problem

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 😊

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

Thanks so much, very helpful for me!

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

This definitely worked for me. Thanks

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

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 😃

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'
            }
        }
    }
  }
}

work for me like a boss! thank for saving time

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
                buildToolsVersion '26.0.2'
            }
        }
    }
     resolutionStrategy.eachDependency { details ->
        if (details.requested.group == 'com.android.support'
              && !details.requested.name.contains('multidex') ) {
