    <p>My code works fine if the GPS is enabled, but when it needs to be enabled it force crashes. Something to do with trying to get the location when the GPS is not enabled. I try to open up Settings for the user to enable GPS but it just continues trying to record GPS (hence force-crashing).</p> <p>I don't know when and where to call Main.</p> <p>First <code>StartupSettings</code> is called:</p> <pre><code>public class StartupSettings extends Activity{ boolean hasGps = false; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.startup_dialog); checkGPS(); } public void checkGPS() { LocationHandler2 lh = new LocationHandler2(); hasGps = lh.enableGPS(this); if (hasGps == true) { TextView tv = (TextView) findViewById(R.id.checkGPSConnection); tv.setTextColor(Color.GREEN); } } </code></pre> <p>The <code>enableGPS()</code> method called by the <code>StartUpSettings() Activity</code> above:</p> <pre><code>public class LocationHandler2{ LocationManager mlocManager; public boolean enableGPS(final StartupSettings main) { mlocManager = (LocationManager)main.getSystemService(Context.LOCATION_SERVICE); if(!mlocManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) { //Ask the user to enable GPS AlertDialog.Builder builder = new AlertDialog.Builder(main); builder.setTitle("Location Manager"); builder.setMessage("Would you like to enable GPS?"); builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { //Launch settings, allowing user to make a change Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); main.startActivity(i); } }); builder.setNegativeButton("No", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { //No location service, no Activity main.finish(); } }); builder.create().show(); } else { return true; } return true; } </code></pre> <p>I want to then call <code>Main</code> which starts up an <code>AsyncTask</code> called <code>StartProcess()</code></p> <pre><code>public class Main extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.pages); StartProcess sProcess = new StartProcess(); sProcess.execute(this); } </code></pre> <p>The <code>StartProcess AsyncTask</code>:</p> <pre><code>public class StartProcess extends AsyncTask&lt;Main, Void, Void&gt; { @Override protected Void doInBackground(Main... params) { LocationHandler2 lh = new LocationHandler2(); try { lh.getLocationStartEnd(params[0],0); } catch (InterruptedException e) { e.printStackTrace(); } return null; } } </code></pre> <p>Logcat:</p> <pre><code>02-26 17:33:31.264: E/AndroidRuntime(10560): FATAL EXCEPTION: AsyncTask #1 02-26 17:33:31.264: E/AndroidRuntime(10560): java.lang.RuntimeException: An error occured while executing doInBackground() 02-26 17:33:31.264: E/AndroidRuntime(10560): at android.os.AsyncTask$3.done(AsyncTask.java:200) 02-26 17:33:31.264: E/AndroidRuntime(10560): at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:273) 02-26 17:33:31.264: E/AndroidRuntime(10560): at java.util.concurrent.FutureTask.setException(FutureTask.java:124) 02-26 17:33:31.264: E/AndroidRuntime(10560): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:307) 02-26 17:33:31.264: E/AndroidRuntime(10560): at java.util.concurrent.FutureTask.run(FutureTask.java:137) 02-26 17:33:31.264: E/AndroidRuntime(10560): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1068) 02-26 17:33:31.264: E/AndroidRuntime(10560): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:561) 02-26 17:33:31.264: E/AndroidRuntime(10560): at java.lang.Thread.run(Thread.java:1096) 02-26 17:33:31.264: E/AndroidRuntime(10560): Caused by: java.lang.IllegalArgumentException: provider==null 02-26 17:33:31.264: E/AndroidRuntime(10560): at android.location.LocationManager.requestLocationUpdates(LocationManager.java:653) 02-26 17:33:31.264: E/AndroidRuntime(10560): at mfc.generalguixapi8.LocationHandler2.getLocationStartEnd(LocationHandler2.java:120) 02-26 17:33:31.264: E/AndroidRuntime(10560): at mfc.generalguixapi8.StartProcess.doInBackground(StartProcess.java:13) 02-26 17:33:31.264: E/AndroidRuntime(10560): at mfc.generalguixapi8.StartProcess.doInBackground(StartProcess.java:1) 02-26 17:33:31.264: E/AndroidRuntime(10560): at android.os.AsyncTask$2.call(AsyncTask.java:185) 02-26 17:33:31.264: E/AndroidRuntime(10560): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305) 02-26 17:33:31.264: E/AndroidRuntime(10560): ... 4 more 02-26 17:34:37.694: E/global(10620): Deprecated Thread methods are not supported. 02-26 17:34:37.694: E/global(10620): java.lang.UnsupportedOperationException 02-26 17:34:37.694: E/global(10620): at java.lang.VMThread.stop(VMThread.java:85) 02-26 17:34:37.694: E/global(10620): at java.lang.Thread.stop(Thread.java:1379) 02-26 17:34:37.694: E/global(10620): at java.lang.Thread.stop(Thread.java:1344) 02-26 17:34:37.694: E/global(10620): at mfc.generalguixapi8.SplashScreen$1.run(SplashScreen.java:36) 02-26 17:36:18.134: E/global(10713): Deprecated Thread methods are not supported. 02-26 17:36:18.134: E/global(10713): java.lang.UnsupportedOperationException 02-26 17:36:18.134: E/global(10713): at java.lang.VMThread.stop(VMThread.java:85) 02-26 17:36:18.134: E/global(10713): at java.lang.Thread.stop(Thread.java:1379) 02-26 17:36:18.134: E/global(10713): at java.lang.Thread.stop(Thread.java:1344) 02-26 17:36:18.134: E/global(10713): at mfc.generalguixapi8.SplashScreen$1.run(SplashScreen.java:36) </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.
