Question

我已经研究了一段时间并尝试过很多东西，但是，我还没有弄清楚这个错误，为了帮助我将我的代码包含在内，它理论上应该起作用，因为它是一个反应的例子-native-android-speech https://github.com/mihirsoni/react-native-android-speech我在尝试中覆盖了大多数方法，我不确定是不是因为它是在不久前编写的，并且与较新版本的反应存在一些兼容性问题。

main activity.java 包com.zero;

import android.os.Bundle;

public class MainActivity extends ReactActivity implements DefaultHardwareBackBtnHandler {

    @Override
    protected String getMainComponentName() {
        String stuff = this.getComponentName().toString();
        return stuff;
    }

    @Override
    public boolean getUseDeveloperSupport(){
        return BuildConfig.DEBUG;

        return Arrays.<ReactPackage>asList(
                new MainReactPackage());
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ReactRootView mReactRootView = new ReactRootView(this);

        ReactInstanceManager mReactInstanceManager = ReactInstanceManager.builder()

提前感谢您的帮助。

当您使用最新版本的react时，我认为您不应该覆盖onCreate，而是尝试在packages数组中添加插件

import android.os.Bundle;

import com.facebook.react.LifecycleState;
import com.facebook.react.ReactActivity;
import com.facebook.react.ReactInstanceManager;
import com.facebook.react.ReactPackage;
import com.facebook.react.ReactRootView;
import com.facebook.react.modules.core.DefaultHardwareBackBtnHandler;
import com.facebook.react.shell.MainReactPackage;
import com.mihir.react.tts.*;

import java.util.Arrays;
import java.util.List;

public class MainActivity extends ReactActivity implements DefaultHardwareBackBtnHandler {

    @Override
    protected String getMainComponentName() {
        return "zero";
    }

    @Override
    public boolean getUseDeveloperSupport(){
        return BuildConfig.DEBUG;
    }

    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
                new MainReactPackage(),
                new RCTTextToSpeechModule());
    }

}
