I am using Biggu barcode library.
Packaged library has been listed everything using demo and sample application.
But I am getting no class definition found error
java.lang.NoClassDefFoundError: com.biggu.scannerdemo.ScannerActivity
But the class is in package and manifest file lists all the activities.
Build path has biggu_scanner-1.1.0.jar file in its path.
package com.biggu.scannerdemo;
import com.biggu.barcodescanner.client.android.Intents;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class Demo extends Activity {
private static final int SCANNER_REQUEST_CODE = 0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button)findViewById(R.id.btn);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), com.biggu.scannerdemo.ScannerActivity.class);
intent.putExtra(Intents.Preferences.ENABLE_BEEP, true);
intent.putExtra(Intents.Preferences.ENABLE_VIBRATE, true);
((Activity)v.getContext()).startActivityForResult(intent, SCANNER_REQUEST_CODE);
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK && requestCode == SCANNER_REQUEST_CODE) {
Bundle extras = data.getExtras();
String result = extras.getString("SCAN_RESULT");
TextView textView = (TextView)findViewById(R.id.txt);
textView.setText(result);
}
}}
ScannerActivity is having the below code
package com.biggu.scannerdemo;
import com.biggu.barcodescanner.client.android.CaptureActivity;
public class ScannerActivity extends CaptureActivity {
@Override
public int get_R_id_preview_view() {
return R.id.preview_view;
}
@Override
public int get_R_id_viewfinder_view() {
return R.id.viewfinder_view;
}
@Override
public int get_R_layout_scanner() {
return R.layout.scanner;
}
@Override
public int get_R_raw_beep() {
return R.raw.beep;
}
}
Android manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
