    <p>Im building a custom home screen with a custom lockscreen.</p> <p>When the screen turn off, I launch the lock screen (activity), However, when the lock screen is killed (by "finish()"), it goes back to the last activity in my homescreen apk, and not to the real activity (apk) that was visible right before the screen went off.</p> <p>For example, if i'm in Calculator application, or in Clock applicaiton, And the lock screen turns on, When the lock screen activity is finished, It doesn't return to Calculator/Clock</p> <p>Here's where I register the lock screen (in the main launcher activity) for receiving screen on/off events:</p> <pre><code>private void doLockScreenOperations() { KeyguardManager keyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE); lock.disableKeyguard(); IntentFilter lockfiFilter = new IntentFilter(); lockfiFilter.addAction(Intent.ACTION_SCREEN_OFF); lockfiFilter.addAction(Intent.ACTION_SCREEN_ON); getApplicationContext().registerReceiver(new LockScreenReceiver(), lockfiFilter); } </code></pre> <p>Here's the receiver itself, where I launch the lock screen's activity:</p> <pre><code>public class LockScreenReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (action.equals(Intent.ACTION_SCREEN_OFF)) { if (LockScreenActivity.isLockScreenAlive == false) { Intent lockIntent = new Intent(context, LockScreenActivity.class); lockIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(lockIntent); } } else if (action.equals(Intent.ACTION_SCREEN_ON)) { } } } </code></pre> <p>The LockScreenActivity is, at that moment, a simple activity with a button that is called finish() when the button is clicked.</p> <p>I have no idea how to fix this.</p> <p>Thanks in advance!</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.
