- 1)Create a package name
wxapi
under the projectandroid
directory/app/src/main/java/packageName
, and then create a newWXEntryActivity
under this package name, the code is as follows:
package packageName.wxapi;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import com.tencent.mm.opensdk.constants.ConstantsAPI;
import com.tencent.mm.opensdk.modelbase.BaseReq;
import com.tencent.mm.opensdk.modelbase.BaseResp;
import com.tencent.mm.opensdk.modelbiz.SubscribeMessage;
import com.tencent.mm.opensdk.modelbiz.WXLaunchMiniProgram;
import com.tencent.mm.opensdk.modelbiz.WXOpenBusinessView;
import com.tencent.mm.opensdk.modelbiz.WXOpenBusinessWebview;
import com.tencent.mm.opensdk.modelmsg.SendAuth;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.IWXAPIEventHandler;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;
public class WXEntryActivity extends Activity implements IWXAPIEventHandler {
private IWXAPI api;
@Override
protected void onCreate(Bundle savedInstanceState) {
Log.d("flutter_wechat_login", "onCreate");
super.onCreate(savedInstanceState);
api = WXAPIFactory.createWXAPI(this, "", false);
try {
Intent intent = getIntent();
api.handleIntent(intent, this);
}
catch (Exception e) {
e.printStackTrace();
}
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
api.handleIntent(intent, this);
}
@Override
public void onReq(BaseReq req) {
}
@Override
public void onResp(BaseResp resp) {
Log.d("flutter_wechat_login", "onResp -> " + resp.errCode);
Intent intent = new Intent("flutter_wechat_login");
intent.putExtra("errCode", resp.errCode);
intent.putExtra("errStr", resp.errStr);
intent.putExtra("type", resp.getType());
if (resp.getType() == ConstantsAPI.COMMAND_SENDAUTH) {
SendAuth.Resp authResp = (SendAuth.Resp) resp;
Log.i("flutter_wechat_login", "COMMAND_SENDAUTH");
intent.putExtra("code", authResp.code);
intent.putExtra("state", authResp.state);
intent.putExtra("lang", authResp.lang);
intent.putExtra("country", authResp.country);
}
sendBroadcast(intent);
finish();
}
}
- 2)Configure
android/app/src/main/AndroidManifest.xml
WeChat needs to verify the package name, so the path of the Activity must be
your package name.wxapi.WXEntryActivity
, whereyour package name
must be the package name filled in by the WeChat open platform registration application.
