Ecco il file mia Gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 19 
    buildToolsVersion "23.0.0 rc2" 

    defaultConfig { 
     applicationId "lk.lankahomes.baman.srilankatemples" 
     minSdkVersion 16 
     targetSdkVersion 21 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile 'com.android.support:appcompat-v7:21.0.1' 
    compile 'com.android.support:recyclerview-v7:21.0.1' 
} 

qualcuno può aiutarmi a risolvere questo problema grazie.

Answer 1

E ' succede perché il 21.0.1per librerie di supportonon esiste.

È possibile utilizzare in build.gradle uno di questi:

dependencies{ 

    //it requires compileSdkVersion 23 
    compile 'com.android.support:appcompat-v7:23.2.0' 
    compile 'com.android.support:appcompat-v7:23.1.1' 
    compile 'com.android.support:appcompat-v7:23.1.0' 
    compile 'com.android.support:appcompat-v7:23.0.1' 
    compile 'com.android.support:appcompat-v7:23.0.0' 

    //it requires compileSdkVersion 22 
    compile 'com.android.support:appcompat-v7:22.2.1' 
    compile 'com.android.support:appcompat-v7:22.2.0' 
    compile 'com.android.support:appcompat-v7:22.1.1' 
    compile 'com.android.support:appcompat-v7:22.1.0' 
    compile 'com.android.support:appcompat-v7:22.0.0' 

    //it requires compileSdkVersion 21 
    compile 'com.android.support:appcompat-v7:21.0.3' 
    compile 'com.android.support:appcompat-v7:21.0.2' 
    compile 'com.android.support:appcompat-v7:21.0.0' 

} 

La stessa considerazione è valida anche per il com.android.support:recyclerview-v7

Answer 2

Penso che la causa sia la linea buildToolsVersion "23.0.0 rc2".

cambiamento a buildToolsVersion "21.0.1"

o provare

compileSdkVersion 21 
buildToolsVersion "22.0.1" 

e

compile 'com.android.support:appcompat-v7:22.2.0' 

e sì quello sharj ha detto è anche corretto, è forse mancano gli strumenti di costruzione

Answer 3

ho affrontato problema simile e installato SDK Android costruire strumenti -v23.0.1 e riferito Android guida all'installazione https://facebook.github.io/react-native/docs/android-setup.html#content

ma non è stato possibile individuare "repository di supporto Android", per l'ultima versione del gestore SDK, l'opzione è stata modificata in "repository locale di Maven per la libreria di supporto ies".
