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?
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:
- Android SDK Tools, revision 24.0.2
- Android SDK Platform-tools, revision 23.0.2
- 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.
Answer:
You should install Android SDK Build Tools 23.0.1 via Android SDK. Don’t forget to check Show Packages Details
.
Answer:
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.
Answer:
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).
Answer:
I had this error:
Failed to find Build Tools revision 23.0.2
When you got updated/installed:
- Android SDK Build Tools
- Android SDK Tools
Change version number in build.gradle
FROM
buildToolsVersion "23.0.2"
TO
buildToolsVersion "25.0.2"
Answer:
Check your $ANDROID_HOME, sometimes is /usr/local/opt/android, but it’s not your install sdk path, change it and fix this problem
Answer:
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"
Answer:
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.
Answer:
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.
Answer:
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….
Answer:
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.
Answer:
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.
