    <p>I have used the same way of Zxing Intent to open scanner from my application. But my application just opens scanner and does nothing. Also, I am getting some FileNotfoundException. </p> <p>Do I have to add any permission in manifest?</p> <p>This is my class where I use Intent:</p> <pre><code>public class BarCodes extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button ok; ok=(Button) findViewById(R.id.b1); ok.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent intent = new Intent("com.google.zxing.client.android.SCAN"); intent.setPackage("com.google.zxing.client.android"); intent.putExtra("SCAN_MODE","QR_CODE_MODE"); startActivityForResult(intent, 0); } }); System.out.println("SSSSSSSSSSSSS"); } public void onActivityResult(int requestCode, int resultCode, Intent intent) { if (requestCode == 0) { if (resultCode == RESULT_OK) { String contents = intent.getStringExtra("SCAN_RESULT"); System.out.println("contentsssssssssssssssssssssss" + contents); String format = intent.getStringExtra("SCAN_RESULT_FORMAT"); // Handle successful scan } else if (resultCode == RESULT_CANCELED) { // Handle cancel } } } } </code></pre> <p>Also LogCat is here:</p> <pre><code>java.lang.RunTimeException:Unable to instantiate activity componentInfo{com.pkg.BarCode...} caused by : java.lang.classNotFoundException:com.pkg.Scan in loader dalvik.System Loader… </code></pre> <p>What might be the problem?? </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
