Android Gradle project sync failed due to target version

Question

Since a new API of Android 6.0 is available in SDK Manager a hint was appeared in application level build.gradle file to update

FROM

androidTestCompile 'com.android.support:support-annotations:22.0.1' compile 'com.android.support:appcompat-v7:22.0.1' 

TO

androidTestCompile 'com.android.support:support-annotations:23.0.0'     compile 'com.android.support:appcompat-v7:23.0.0' 

I haven't downloaded new update from sdk manager for Android 6(API 23) yet but still changed the following details as shown below,

BEFORE

compileSdkVersion 22 buildToolsVersion "22.0.1" targetSdkVersion 22 androidTestCompile 'com.android.support:support-annotations:22.0.1' compile 'com.android.support:appcompat-v7:22.0.1' 

AFTER

    compileSdkVersion 23     buildToolsVersion "23.0.0"     targetSdkVersion 23     androidTestCompile 'com.android.support:support-annotations:23.0.0'     compile 'com.android.support:appcompat-v7:23.0.0' 

As I haven't downloaded new API 6.0 yet, following error occurred

Error:Cause: failed to find target with hash string 'android-23' in: C:\Users\DRONE\AppData\Local\Android\sdk 

So now again I changed the setting in application level build.gradle file as what it was before, but the error is not being resolved. Same error is occurring.

How do I solve this now?

Answer 1

Normally it is caused by not having API 23. After updating the SDK to the newer version, it often rewrites build.gradle to the highest API version SDK provided even if you didn't upload it. The easiest way - download API 23.

Answer 2

I think it may caused by you don't have 23 API, Go to Tools > Android > SDK Manager and check to see if API-23 is installed.
