Question

我在android应用程序中完成了QR扫描程序的实现。它确实在6.0和其他一些操作系统版本中工作，但是当我点击QR扫描仪没有获得句柄意图时它在棒棒糖5.1版本中崩溃了。

代码：

     public  void aadahrScan() {
            Intent intent = new Intent("com.google.zxing.client.android.SCAN");
            startActivityForResult(intent, 0);
        }

     @Override
        public void onActivityResult(int requestCodeTools, int resultCodeTools, Intent intentTools) {
            if (requestCodeTools == 0 && intentTools != null) {
                requestCodeTools(resultCodeTools, intentTools);
            }
        }

Error:

我添加了清单文件，但我也提供了访问摄像机所需的所有权限

请事先解决此问题

将此添加到您的canActivate(): Observable<boolean> { return this.auth.authState .take(1) .map(authState => !!authState) .do(auth => !auth ? this.router.navigate(['/login']) : true); }：
