public class WXPayEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {
private static final String TAG = "MicroMsg.SDKSample.WXPayEntryActivity";
private IWXAPI api;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
api = WXAPIFactory.createWXAPI(this, "your wechat appid");
api.handleIntent(getIntent(), this);
}
@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) {
//add your code logic...
Log.d(TAG, "onPayFinish, errCode = " + resp.errCode);
if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {
if (resp.errCode == BaseResp.ErrCode.ERR_OK) {
Log.d(TAG, "success");
} else if (resp.errCode == BaseResp.ErrCode.ERR_SENT_FAILED || resp.errCode == BaseResp.ErrCode.ERR_COMM) {
Log.d(TAG, "failed");
} else if (resp.errCode == BaseResp.ErrCode.ERR_USER_CANCEL) {
Log.d(TAG, "user cancel");
