    <p>I'm new to android and is currently developing a quest/tresurehunt application. It is a prototype and is going to be evaluated in the field and i would therefore like to implement some sort of cheat to skip checkpoints if the application should crash during the tests.</p> <p>My application work the way that when you select a quest a activity will be loaded to handle all checkpoints and the user location(ActivityAdapter.java). This activity will open the diffrent navigation tool activities and pass information to them based on the next checkpont using intent. I have implemented a long press event in the app i would like to activate the skip/cheat. My problem is that i can't figure out how to do this.</p> <p>Location changed event of ActivityAdapter.java:</p> <pre><code>public void onLocationChanged(Location location) { location.distanceBetween(location.getLatitude(), location.getLongitude(), lat, lng, dist); if (dist[0]&lt;= 10) { if (cid == checkpoints.size()) { Intent intent = new Intent(ActivityAdapter.this, SuccessActivity.class); intent.putExtra("title", checkpoints.get(cid).get("title")); startActivity(intent); } else { new loadAndStartQuest().execute(); } } } </code></pre> <p>loadAndStartQuest() just find the next checkpoint and start the right activity (navigationtool). I have tryed creating a object of the ActivityAdapter and set a variable and add it to the the if statement which did not work. I guess it is because it will create another instance of the activity and not affect the current/running one. So how would you communicate between two running activities?</p>

    1. COI am not an Android developer, but in my Java code, when I needed to pass stuff between running processes, I usually either used an event listener model, some pub/sub topic, or simply had setter methods to set flags between the running objects/threads, depending on how fancy I wanted to be. Or, better yet...why not simply make your "cheat" call the code to mark the quest as completed, then the normal code would just flow right past it, right?

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.
