Failed to find Build Tools revision 23.0.1

问题:

I am trying to build my first app with react-native.

I am following these 2 tutorial:

• https://facebook.github.io/react-native/docs/getting-started.html#content
• https://facebook.github.io/react-native/docs/android-setup.html

I am sure that I installed all the requirements from the second link but when I try running my app with react-native run-android, I get the following error:

I executed this command while running genymotion.

This is all that I have installed in Android SDK:

I tried to install Android build tools 23.0.1 but I get this error:

What should I do?

回答1:

I faced the same problem and I solved it doing the following:

Go to /home/[USER]/Android/Sdk/tools and execute:

$android list sdk -a

Which will show a list like:

1. Android SDK Tools, revision 24.0.2
2. Android SDK Platform-tools, revision 23.0.2
3. Android SDK Platform-tools, revision 23.0.1

... and many more

Then, execute the command (attention! at your computer the third option may be different):

$android update sdk -a -u -t 3

It will install the 23.0.1 SDK Platform-tools components.

Try to build your project again.

回答2:

You should install Android SDK Build Tools 23.0.1 via Android SDK. Don't forget to check Show Packages Details.

回答3:

Either install v23.0.1 of the build tools (the fifth row in your screenshot), or change your code to use the build tools version you already have installed (v23.0.3). This can be specified in your app's build.gradle file:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        ...
    }
}

As per duncanc4's comment below,

The build.gradle file you want to edit is in the android/app folder within your project directory.

回答4:

The error you're getting seems to be related to system's permissions, since it's not able to create a folder.

Try running the sdk-manager using root (with su or sudo commands).

回答5:

I had this error:

Failed to find Build Tools revision 23.0.2

When you got updated/installed:

1. Android SDK Build Tools
2. Android SDK Tools

Change version number in build.gradle

FROM

buildToolsVersion "23.0.2"

TO

buildToolsVersion "25.0.2"

How to find what Build Tools version you have

回答6:

Check your $ANDROID_HOME, sometimes is /usr/local/opt/android, but it's not your install sdk path, change it and fix this problem

回答7:

While running react-native In case you have installed 23.0.3 and it is asking for 23.0.1 simply in your application project directory. Open anroid/app/build.gradle and change buildToolsVersion "23.0.3"

Nothing helped until I found this solution : https://stackoverflow.com/a/39068538/3995091

In Android SDK, the build tools with the correct version where shown as installed, but still I got the same error saying they couldn't be found. When I used the above solution, I found out they were indeed not installed, although Android SDK thought they were. Installing them solved it for me.

回答9:

In the Gradle Console (link available in the window bottom right), you have two tabs: the error is shown in Gradle Build tab. Click on the Gradle Sync tab, then click on the Install Build Tools XX.X.X and sync project link. This will download the build version required by your project.

You may also change your project SDK version but you don't always have this option if it is imposed.

回答10:

If you already install the correct Android SDK Platform-Tools (Build Tool) and you still get an error, try to invalidate the cache; File -> Invalidate caches / Restart....

回答11:

On my system, Android SDK Manager showed /usr/local/Cellar/android-sdk as the SDK path, when $ANDROID_HOME was /Users/james/Library/Android/sdk. I just added a symlink for the correct build tools version.

回答12:

Two solutions: You have to instal the required buildToolVersion or set it as described above.
Notice that if you are trying to set the buildToolsVersion "23.0.3" using Android Studio 3.0 or more it won't work until you remove all builversion you have keeping just one last version you use. I read this somewhere else and this works for me. Hope this helps.

Just install it from Android Studio ;)
