reaktives Ausführen von Android mit Fehler fehlgeschlagen: Ausführung fehlgeschlagen für Task ': app: dexDebug'
Ich verwende Windows 8.1. mit react-native-cli: 1.0.0 und react-native: 0.31.0
Nachdem ich react-native-maps zum Projekt hinzugefügt hatte, führte ich den Befehl react-native upgrade aus und gabYzu allen Fragen. Dann verknüpfte deps mit rnpm link sowie Änderungen in der MainApplication.Java-Datei.
Hier sind Änderungen an MainApplication.Java:
// 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;
}
}
Jetzt erhalte ich eine Fehlermeldung, wenn ich den Befehl ausführt: react-native run-Android
λ react-native run-Android
JS server already running.

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
Ich habe keine Ahnung von diesem Fehler. Ich sah einige ähnliche Fragen, konnte aber keine Antwort finden. Ich bin neu in der Entwicklung von React-Native und Android, daher habe ich Schwierigkeiten, diese Dinge zu verstehen.
Dieses Problem ist normalerweise auf die Abhängigkeit von neuen Komponenten zurückzuführen. Ich kann sehen, dass Sie React-Native-Maps installiert haben.
sie können es lösen, indem Sie das Projekt reinigen.
- In Ihrem React Native-Projekt:
cd Android/&& ./gradlew sauber
- gehen Sie zurück und versuchen Sie es erneut.
cd .. && reagieren-native run-Android
Verwenden Sie diese Schritte
1.) cd android
2.) gradle sauber
3.) Führen Sie jetzt das Projekt aus.
Dieser Fehler tritt in meinem System auf, wenn der Emulator aktualisiert wird.
um genauer zu sein:
Ändern Sie in Ihrer MainApplication.Java-Datei,
protected boolean getUseDeveloperSupport() { { <-----
auf diesem
public boolean getUseDeveloperSupport() { <-----
das hat es zumindest für mich gebaut
Das Problem für mich war, dass der Packager vom vorherigen Build im Hintergrund ausgeführt wurde.
Sie können einfach versuchen, den Packager-Server zu schließen und mit zu starten
react-native run-Android
Das war für mein Problem erfolgreich.
führen Sie dies einfach aus dem Stammverzeichnis Ihres Projekts mit cmd aus:
cd Android && gradlew clean
