Build Setup for Android

注意

请根据本文档严格配置，否则会导致微信无法回调你的应用，例如授权登录后无法跳回 APP，或者小程序无法拉起 APP 如果配置过程有不明白，可以查看 样本工程 在样本工程里搜索 'react-native-wechat-lib support' 便可以找到所有需要添加配置的地方

注册模块

添加到 MainApplication.java 或 MainActivity.java:

import com.wechatlib.WeChatLibPackage; // Add this line

  @Override
  protected List<ReactPackage> getPackages() {
    @SuppressWarnings("UnnecessaryLocalVariable")
    List<ReactPackage> packages = new PackageList(this).getPackages();
    // Packages that cannot be autolinked yet can be added manually here, for example:
    // packages.add(new MyReactNativePackage());
    packages.add(new WeChatLibPackage()); // Add this line
    return packages;
  }

登录和分享回调

如果您打算集成登录或共享功能，则需要这样做 在应用程序包和类中创建名为 "wxapi" 的包, 命名为 WXEntryActivit

package your.package.wxapi;

import android.app.Activity;
import android.os.Bundle;
import com.wechatlib.WeChatLibModule;

public class WXEntryActivity extends Activity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    WeChatLibModule.handleIntent(getIntent());
    finish();
  }
}

Then add the following node to AndroidManifest.xml:

<manifest>
  <application>
    <activity
      android:name=".wxapi.WXEntryActivity"
      android:label="@string/app_name"
      android:exported="true"
    />
  </application>
</manifest>

Integrating the WeChat Payment

If you are going to integrate payment functionality by using this library, then create a package named also wxapi in your application package and a class named WXPayEntryActivity, this is used to bypass the response to JS level:

package your.package.wxapi;

import android.app.Activity;
import android.os.Bundle;
import com.theweflex.react.WeChatModule;

public class WXPayEntryActivity extends Activity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    WeChatModule.handleIntent(getIntent());
    finish();
  }
}

Then add the following node to AndroidManifest.xml:

<manifest>
  <application>
    <activity
      android:name=".wxapi.WXPayEntryActivity"
      android:label="@string/app_name"
      android:exported="true"
    />
  </application>
</manifest>

如果遇到安卓App拉起小程序后，小程序无法返回App的情况，需要在AndroidManifest.xml的WXEntryActivity中添加下面这段配置:

android:taskAffinity="your packagename"
android:launchMode="singleTask"

保证跳转后回到你的app的task。 实际上，我的代码如下：

<manifest>
  <application>
    <activity
      android:name=".wxapi.WXEntryActivity"
      android:label="@string/app_name"
      android:exported="true"
      android:taskAffinity="org.xxx.xxx.rnapp"
      android:launchMode="singleTask"
    />
  </application>
</manifest>
