Linking Steps

Before using this library to work with your app, you should follow the below steps to link this library with your app project, if there is something that not working, please check the list here.

Linking iOS

  • Link RCTWeChat library from your node_modules/react-native-wechat/ios folder like react-native's Linking Libraries iOS Guidance, Note: Don't forget to add it to "Build Phases" of your target project.

  • Add the following libraries to your "Link Binary with Libraries":

    SystemConfiguration.framework
    CoreTelephony.framework
    libsqlite3.0
    libc++
    libz
    
  • Add "URL Schema" as your app id for "URL type" in Targets > info, See the following screenshot for the view on your XCode Set URL Schema in XCode

  • Only for iOS 9, add wechat and weixin into LSApplicationQueriesSchemes in Targets > info > Custom iOS Target Properties. Or edit Info.plist then add:

      <key>LSApplicationQueriesSchemes</key>
      <array>
        <string>weixin</string>
        <string>wechat</string>
      </array>
    
  • Code the following in AppDelegate.m of your project to enable [LinkingIOS]

    #import "../Libraries/LinkingIOS/RCTLinkingManager.h"
    
    - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
    sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
    {
      return [RCTLinkingManager application:application openURL:url
                                sourceApplication:sourceApplication annotation:annotation];
    }

Linking Android with Gradle

  • Add following lines into android/settings.gradle

    include ':RCTWeChat'
    project(':RCTWeChat').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-wechat/android')
  • Add following lines into your android/app/build.gradle in section dependencies

    dependencies {
      compile project(':RCTWeChat')    // Add this line only.
    }
  • Add following lines into MainActivity.java or MainApplication.java:

    import com.theweflex.react.WeChatPackage;       // Add this line before public class MainActivity
    ...
    
    /**
     * A list of packages used by the app. If the app uses additional views
     * or modules besides the default ones, add more packages here.
     */
    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        new MainReactPackage(), 
        new WeChatPackage()        // Add this line
      );
    }
  • Create a package named 'wxapi' in your application package and a class named 'WXEntryActivity' in it. This is required to get authorization and sharing response from wechat.

    package your.package.wxapi;
    
    import android.app.Activity;
    import android.os.Bundle;
    import com.theweflex.react.WeChatModule;
    
    public class WXEntryActivity extends Activity {
      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        WeChatModule.handleIntent(getIntent());
        finish();
      }
    }
  • (Optional) Create a package named 'wxapi' in your application package and a class named 'WXPayEntryActivity' in it. This is required to get payment response from WeChat.

    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();
      }
    }
  • Add activity declare in your AndroidManifest.xml

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