  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" ></uses-permission>
  <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" ></uses-permission>

如果想要响应微信分享登录resp需要在mainActivity同级目录下创建wxapi文件夹
下面新建WXEntryACtivity集成Activity(需要在AndroidManifest.xml注册）

<activity android:name=".wxapi.WXEntryActivity" android:exported="true" android:launchMode="singleTop"></activity>

    private IWXAPI api;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        api = WXAPIFactory.createWXAPI(this, "wxb25d3dec3db1affc", false);
        onNewIntent(getIntent());
        finish();
    }
        @Override
    public void onReq(BaseReq baseReq) {
    }
    @Override
    public void onResp(BaseResp baseResp) {
        sendBroadcastToWechat(baseResp);
    }
    private void sendBroadcastToWechat(BaseResp baseResp) {
        Intent intent = new Intent();
        intent.setAction("sendResp");
        if (baseResp instanceof SendAuth.Resp) {
            SendAuth.Resp resp = (SendAuth.Resp) (baseResp);
            intent.putExtra("code", resp.errCode == 0 ? resp.code : "-1");
            intent.putExtra("type", "SendAuthResp");
            sendBroadcast(intent);
        } else {
            intent.setAction("sendResp");
            intent.putExtra("code", baseResp.errCode + "");
            intent.putExtra("type", "ShareResp");
            sendBroadcast(intent);
        }
    }
    protected void onNewIntent(Intent intent) {
        api.handleIntent(intent, this);
    }

如果想要响应微信支付resp需要在mainActivity同级目录下创建wxapi文件夹(需要在AndroidManifest.xml注册）

<activity
  android:name=".wxapi.WXPayEntryActivity"
  android:exported="true"
  android:launchMode="singleTop">
  <intent-filter>
      <action android:name="android.intent.action.VIEW"></action>
      <category android:name="android.intent.category.DEFAULT"></category>
      <data android:scheme="your AppId"></data>
  </intent-filter>
</activity>
  下面新建WXEntryACtivity集成Activity

 public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler {
    private IWXAPI api;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        api = WXAPIFactory.createWXAPI(this, "wxb25d3dec3db1affc", false);
        onNewIntent(getIntent());
        finish();
    }
    @Override
    public void onReq(BaseReq baseReq) {
    }
    @Override
    public void onResp(BaseResp baseResp) {
        sendBroadcastToWechat(baseResp);
    }
    private void sendBroadcastToWechat(BaseResp baseResp) {
        Intent intent = new Intent();
        intent.setAction("sendResp");
        intent.putExtra("code", baseResp.errCode + "");
        intent.putExtra("type", "PayResp");
        sendBroadcast(intent);
    }
    protected void onNewIntent(Intent intent) {
        api.handleIntent(intent, this);
    }
}
