Build failed on android.

[zenato]

Hello,

react-native version: 0.56
react-native-pdf version: 3.0.16

I ran test app but an build error occurred.
Check the log below.

react-native run-android
....
FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':app'.

Could not resolve all dependencies for configuration ':app:_debugApk'.
A problem occurred configuring project ':react-native-pdf'.
> The SDK Build Tools revision (23.0.1) is too low for project ':react-native-pdf'. Minimum required is 25.0.0

@zenato you need to bump up the version SDK build Tool in the build.gradle file.

@vikas5914

My build.gradle

ext {
buildToolsVersion = "26.0.3"
minSdkVersion = 16
compileSdkVersion = 26
targetSdkVersion = 26
supportLibVersion = "26.1.0"
}

The cause of this problem seems to be this project build.gradle.

make the targetSdkVersion 22

[zenato]

I used react native v0.56 default configuration.
Do I have to downgrade targetSdkVersion?
Do you have any plans to upgrade targetSdkVersion?

[vikas5914]

sorry, can you try to lower the buildToolsVersion

[zenato]

@vikas5914 Hmm...

I can't downgrade SDK version.

See react native 0.56 release document.
https://github.com/facebook/react-native/releases

Android projects are now compiled using the Android 26 SDK.
The target API level is left unchanged in this release.

Starting August 2018, new apps submitted to the Play Store will need to target API 26 as a minimum. You can now opt your project in to use API 26 (or newer) as the target. Please let us know about any issues, as we'd like to finalize support for Android API 26 by the time 0.57.0 is released.

[wonday]

I have updated android build tool to 26.0.3 at v3.0.17

@wonday Thank you for your upgrade.
I was able to solve the problem.
