    <p>I have an activity, called ScanRouter, that calls ZBar Scanner via startActivityForResult. Once I scan a code, onActivityResult in ScanRouter processes the result, passes the result to another activity via intents and ScanRouter is "finish()".</p> <p>However, after the result is passed to the new activity, if the back button is pressed, ScanRouter reopens ZBar. If I set ScanRouter to noHistory=true, then onActivityResult doesn't work.</p> <p>How can I prevent ScanRouter from firing again if the back button is pressed? I thought finish() would remove it from the stack but that is apparently not true. I would like to go back to the activity that originally called ScanRouter rather than ScanRouter itself.</p> <p>ScanRouter: Portion of the code that matters</p> <pre><code>@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case ZBAR_SCANNER_REQUEST: case ZBAR_QR_SCANNER_REQUEST: if (resultCode == RESULT_OK) { // TODO go back to the caller and give them the result String value = data.getStringExtra(ZBarConstants.SCAN_RESULT); **returnIntent(value);** } else if(resultCode == RESULT_CANCELED &amp;&amp; data != null) { // TODO go back to the caller and give them the error String error = data.getStringExtra(ZBarConstants.ERROR_INFO); if(!TextUtils.isEmpty(error)) { Toast.makeText(this, error, Toast.LENGTH_SHORT).show(); } } break; } } protected void returnIntent(String value) { Intent intent = new Intent(this, Manager.class); intent.putExtra("operation", caller); intent.putExtra("code", value); startActivity(intent); **this.finish();** } </code></pre>

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.
