zxing中的ActivityNotFoundException

Question

I am new in android. I am developing a App in which i have to used zxing for scanning bar code and QR code. In my App i can not use third party software. That means i can't use these line of code in my App

 IntentIntegrator integrator = new IntentIntegrator(shopping.this);
            integrator.initiateScan();

So, in that case i used these line code after reading several tutorial .

    Intent intent = new Intent("com.google.zxing.client.android.SCAN"); 
              intent.setPackage("com.google.zxing.client.android"); 
             // intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
              intent.putExtra("SCAN_FORMATS", "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR,EAN_13,EAN_8,UPC_A,QR_CODE");
              startActivityForResult(intent, 0); 

But unfortunately this is showing Exception for me, my total log-cat output is as follow-

But when i just replace this line

   Intent intent = new Intent("com.google.zxing.client.android.SCAN");

to this line

   Intent intent = new Intent(shopping.this, CaptureActivity.class);

and i run my App it successfully run for me , but problem is that it is only scanning **QR Code , it not working for BAR code . For convenience for those who want to help i am going to show my Manifest file

Answer 1

Do you have this 3rd party application installed in your phone or emulator where ever you are running the application?

Android operating system couldn't find the activity.

          01-06 06:00:02.161: E/AndroidRuntime(956): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.google.zxing.client.android.SCAN pkg=com.google.zxing.client.android (has extras) }

Use try and catch block, make sure the application is installed in your phone, if it's not : point the user to 3rd party application on playstore.

Answer 2

使用提供的IntentIntegrator类，因为它将处理您需要处理的情况，例如未安装应用程序。

Answer 3

You are getting ActivityNotFoundException as Zxing application is not installed in your device. So Please check whether it is installed or not. If it's not then redirect user to playstore-page of Zxing:

I've implemented some code for these. Modify it according to your needs:

boolean isZxingInstalled;
/*
 *Checking whether Zxing is installed or not
 */ 
try
{
ApplicationInfo info = getPackageManager().getApplicationInfo("com.google.zxing.client.android", 0 );
boolean isZxingInstalled = true;
    }
catch(PackageManager.NameNotFoundException e){
                isZxingInstalled=false;
          }

/*
 * Store the boolean value on the basis of Zxing is installed or not
 */

if(isZxingInstalled) //If it is then intent Zxing application
 {
         //start the facebook app
         Intent intent = new Intent("com.google.zxing.client.android.SCAN");
          intent.setPackage("com.google.zxing.client.android"); 
          intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
          intent.putExtra("SCAN_FORMATS",    "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR,EAN_13,EAN_8,UPC_A,QR_CODE");
          startActivityForResult(intent, 0); 
  }
 else //It's not then redirect user to PlayStore-ZxingPlage
  {
    /*
     *Checking whether PlayStore is installed in device or not?
     */
     boolean isPlayStoreInstalled
     try
     {
      ApplicationInfo i=getPackageManager().getApplicationInfo("com.google.vending", 0 );
      boolean isPlayStoreInstalled = true;
      }
     catch(PackageManager.NameNotFoundException e){
                isPlayStoreInstalled=false;
          }

      /*
       * If it is the download Zxing
       */ 
      if(isPlayStoreInstalled)
       {
        Intent DownloadZxing = new Intent(Intent.ACTION_VIEW,Uri.parse("market://detailsid=com.google.zxing.client.android"));
        startActivity(DownloadZxing);
        }
      else //Toast message indicating No PlayStore Found
       {
         Toast.makeText(this,"Install PlayStore First",Toast.LENGHT_SHORT).show();
        }
  }

Hope these may help!! :)
