react-native run-Androidがエラーで失敗しました:タスク ':app:dexDebug'の実行に失敗しました

私はWindows8.1を使用しています。 react-native-cli: 1.0.0およびreact-native: 0.31.0を使用

プロジェクトにreact-native-mapsを追加した後、コマンドreact-native upgradeを実行し、すべての質問に[〜#〜] y [〜#〜]を指定しました。次に、depsをrnpm linkにリンクし、MainApplication.Javaファイルにも変更を加えます。

MainApplication.Javaの変更点は次のとおりです。

// Other imports ...
import com.airbnb.Android.react.maps.MapsPackage;

public class MainApplication extends Application implements ReactApplication {

 private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
    @Override
    protected boolean getUseDeveloperSupport() {
       return BuildConfig.DEBUG;
    }

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
         new MainReactPackage(),
         new MapsPackage() // I have added this for react-native-maps
      );
    }
  };

 @Override
 public ReactNativeHost getReactNativeHost() {
   return mReactNativeHost;
 }
}

次のコマンドを実行するとエラーが発生します:react-native run-Android

このエラーについてはわかりません。これに似た質問をいくつか見ましたが、答えが見つかりませんでした。私はReact-NativeとAndroid開発に慣れていないので、このことを理解するのに苦労しています。

この問題は通常、新しいコンポーネントのgradle依存関係に起因します。インストールしたことがわかりますreact-native-maps

プロジェクトをクリーンアップすることで解決できます。

  1. あなたのReactネイティブプロジェクト:

cd Android/&& ./gradlew clean

  1. 戻って、もう一度実行してみてください。

cd .. && react-native run-Android

25

これらの手順を使用します

1.)cd Android

2.)gradle clean

3.)プロジェクトを実行します。

このエラーは、エミュレータが更新されるたびにシステムで発生します。

もう少し詳しく言うと:

あなたのMainApplication.Javaファイル、変更、

protected boolean getUseDeveloperSupport() { { <-----

これについて

public boolean getUseDeveloperSupport() { <-----

少なくとも私のためにそれを構築しました

私にとっての問題は、パッケージャーが前のビルドのバックグラウンドで実行されていたことでした。

パッケージャサーバーを閉じて、次のコマンドで起動しようとする場合があります。

react-native run-Android

それは私の問題のために成功しました。

cmdを使用してプロジェクトのルートからこれを実行するだけです。

cd Android && gradlew clean
