问题描述：

E/MicroMsg.SDK.WXApiImplV10: register app failed for wechat appsignature check failed 2021-06-22 17:31:42.655
E/MicroMsg.SDK.WXApiImplV10:sendReq failed for wechat app signature check failed

解决方案：

注册失败，所以是漏了，补上。

  api = WXAPIFactory.createWXAPI(ApplicationUtils.getInstance().getActivity(),BuildConfig.WECHAT_APP_ID,false);
  api.registerApp(BuildConfig.WECHAT_APP_ID);

问题描述：

E/ActivityThread: Failed to find provider info for com.tencent.mm.sdk.comm.provider
E/MicroMsg.SDK.MMessageAct: send fail, ex = Unable to find explicit activity class {com.tencent.mm/com.tencent.mm.plugin.base.stub.WXEntryActivity}; have you declared this activity in your androidManifest.xml?

解决方案：

经过一番排查，最终发现，其实是测试机没有安装微信哈哈哈。解决方案，判断手机是否安装了微信：

 public static boolean isWeixinAvilible(Context context) { 
    final PackageManager packageManager = context.getPackageManager();// 获取packagemanager 
    List<PackageInfo> pinfo = packageManager.getInstalledPackages(0);// 获取所有已安装程序的包信息 
    if (pinfo != null) { 
      for (int i = 0; i < pinfo.size(); i++) { 
        String pn = pinfo.get(i).packageName; 
        if (pn.equals("com.tencent.mm")) { 
          return true; 
        } 
      } 
    } 
    return false; 
  }
