Question

I have made Qr code Scanner using Intent using Zxing library and i have kept Library in application so that my app no longer require barcode scanner. But When barcode scanner is already in operating system, when i start my application , a dialog box appear asking complete action using : barcode scanner or My application . When I have all library in my own application Then how can i avoid this Dialog Box. Please help me out.

Example code :

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

Answer 1

To use:

Intent intent=new Intent("com.google.zxing.client.android.SCAN");
intent.setClassName("com.google.zxing.client.android", "com.google.zxing.client.android.CaptureActivity");
startActivityForResult(intent, 0);

Or:

Intent intent=new Intent("com.google.zxing.client.android.SCAN");
intent.setClassName(this, "com.google.zxing.client.android.CaptureActivity");
startActivityForResult(intent, 0);
