关于React Native windows 下踩过的坑总结(都是从网上找来的)

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()
);
}
};

@Override
public ReactNativeHost getReactNativeHost() {
return mReactNativeHost;
}
}
上面不要忘了 在清单文件中配置啊

import com.facebook.react.ReactActivity;

public class MainActivity extends ReactActivity {

/**
* Returns the name of the main component registered from JavaScript.
* This is used to schedule rendering of the component.
*/
@Override
protected String getMainComponentName() {
return "<%= name %>";
}
}

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.zhangyu.android/com.facebook.react.devsupport.DevSettingsActivity}; have you declared this activity in your AndroidManifest.xml?

<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />

用手机比较比较容易出问题 ,于是乎我就用夜神模拟器, 可是 adb devices 也检测不到
　
解决方法 : 控制台cd进Android SDK下的platform-tools目录，然后执行
代码:
adb connect 127.0.0.1:62001
