Question

我正在开发一个Android应用程序，我的主类代码是这样的。

但它在启动相机前显示错误。我该如何解决这个问题？

 public void onClick(View view) {
            Intent intent = new Intent("com.google.zxing.client.android.SCAN");
            intent.putExtra("SCAN_FORMATS", "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR");
            startActivityForResult(intent, 0);    //Barcode Scanner to scan for us
        }
    });

这是我的STACKTRACE

Answer 1

android.content.ActivityNotFoundException：找不到处理Intent的活动{act = com.google.zxing.client.android.SCAN}

您需要先安装ZXing应用程序，然后再尝试通过Intent使用它。

考虑使用IntentIntegrator方法自动检查和安装ZXIng应用程序。

在我的Android应用程序上使用zxing扫描仪时出错
