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
λ react-native run-Android

Make sure you have an Android emulator running or a device connected and have set up your Android development environment:
https://facebook.github.io/react-native/docs/Android-setup.html
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。
- あなたのReactネイティブプロジェクト：
cd Android/&& ./gradlew clean
- 戻って、もう一度実行してみてください。
cd .. && react-native run-Android
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
