Clean Blank Android App fails to build - 'fail

问题:

New to Android, Tried to build a clean 'Blank App' android project.

I get the below error, which is confusing because I have version 24 installed using the SDK manager not sure why its looking for versoin 23. It doesn't give me any kind of line number to look at though, any suggestions? Thank you.

Open the SDK Manager and find the version of the Android SDK Build-tools which is installed and that you want to use. Then go to Gradle Scripts > build.gradle (Module: app). Set the buildToolsVersion to your version.

Edit: There is an easier solution. Right click on the project > Open Module Settings. Choose the Complie Sdk Version and Build Tools Version you want to use.

If you cannot find 23.0.0 rc1 in sdk mananger, you can modify gradle's sdk version. How? edit build.gradle like this, and change buildToolsVersion.

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.sunjiajia.androidnewwidgetsdemo"
        minSdkVersion 14
            targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

find the BuildTools ids you want to install,

ANDROID_HOME=/Users/prayagupd/Library/Android/sdk/

$ANDROID_HOME/tools/android list sdk -a | grep "revision 23"
  10- Android SDK Build-tools, revision 23.0.3
  11- Android SDK Build-tools, revision 23.0.2
  12- Android SDK Build-tools, revision 23.0.1
  13- Android SDK Build-tools, revision 23 (Obsolete)

Then, install the buildTool version you want, eg. 23.0.1 as 23 is obsolete.

$ANDROID_HOME/tools/android update sdk -a -u -t 12

You can achieve the same thing using

$ANDROID_HOME/tools/android sdk

which will show the buildTools in UI as below,

Then ./gradlew clean build should be SUCCESSFUL.
