Build Setup for Android

Copy lines to android/settings.gradle:

include ':RCTWeChat'
project(':RCTWeChat').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-wechat/android')

Copy lines to android/app/build.gradle

dependencies {
  implementation project(':RCTWeChat') // Add this line
}

Copy lines to proguard-rules.pro:

-keep class com.tencent.mm.sdk.** {
  *;
}

Then update MainActivity.java or MainApplication.java:

import com.theweflex.react.WeChatPackage; // 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 WeChatPackage()); // Add this line
    return packages;
  }

Integrating with login and share

If you are going to integrate login or share functions, you need to create a package named 'wxapi' in your application package and a class named WXEntryActivity in it.

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();
  }
}

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>
