    <p>I am using actionbarsherlock and its sherlockFragmentActivity.</p> <p>I have 3 fragments and in a Tab + ViewPager layout.</p> <p>The 3rd fragment is the problem. It is a fragment that displays my location on a google maps.</p> <p>From what I notice, viewpager, will CREATE the new page, and if we scroll away from a page for more than 1 page, then it will DESTORY that page.</p> <p>So its all fine the first time around, i go to page 2, and it calls CREATE on page3 with GOOGLEMAPS. </p> <p>HOWEVER, the problem is if i go back to page 1 (DESTORIES page 3 googlemaps). Now if i go back to page 2 (tries to create page3), page3's inflater.inflate will DIE and i'll get an error, first is the Choreographer class.</p> <p>So my question is, WHY IS inflater.inflate failing, and WHAT IS THE PROPER way to program tab viewpager with fragments like this.???</p> <p>Code here (ON create of main activity):</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getWindow().setFlags(LayoutParams.FLAG_FULLSCREEN, LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.main_activity); mTabHost = (TabHost)findViewById(android.R.id.tabhost); mTabHost.setup(); mViewPager = (ViewPager)findViewById(R.id.pager); mTabsAdapter = new TabsAdapter(this, mTabHost, mViewPager); mTabsAdapter.addTab(mTabHost.newTabSpec("driverInfo").setIndicator("Driver Info"), DriverInfo.class, null); mTabsAdapter.addTab(mTabHost.newTabSpec("alarmSystem").setIndicator("Alarm System"), AlarmSetting.class, null); mTabsAdapter.addTab(mTabHost.newTabSpec("vehicleLocation").setIndicator("Location"), VehicleLocation.class, null); if (savedInstanceState != null) { mTabHost.setCurrentTabByTag(savedInstanceState.getString("tab")); } } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("tab", mTabHost.getCurrentTabTag()); } </code></pre> <p>Code: Location Fragment:</p> <pre><code>public class VehicleLocation extends Fragment implements ServerRequestInterface { private GoogleMap mMap; private ProgressDialog mProgressDialog; @Override public void onCreate(Bundle savedInstanceState) { try { super.onCreate(savedInstanceState); setupProgressDialog(); } catch (Exception ex) { System.out.println(ex.toString()); } } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { //WHere it keeps die-ing ---------------------------------- View view = inflater.inflate(R.layout.vehicle_location, container, false); setUpMapIfNeeded(); return view; } </code></pre> <p>Error Log:</p> <pre><code>05-13 20:48:31.532: E/AndroidRuntime(13219): FATAL EXCEPTION: main 05-13 20:48:31.532: E/AndroidRuntime(13219): android.view.InflateException: Binary XML file line #2: Error inflating class fragment 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:704) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.view.LayoutInflater.inflate(LayoutInflater.java:466) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.view.LayoutInflater.inflate(LayoutInflater.java:396) 05-13 20:48:31.532: E/AndroidRuntime(13219): at com.covixon.main.VehicleLocation.onCreateView(VehicleLocation.java:37) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.app.Fragment.performCreateView(Fragment.java:1460) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:911) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1088) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.app.BackStackRecord.run(BackStackRecord.java:682) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1444) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.app.FragmentManagerImpl.executePendingTransactions(FragmentManager.java:461) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.app.FragmentStatePagerAdapter.finishUpdate(FragmentStatePagerAdapter.java:163) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.view.ViewPager.populate(ViewPager.java:1011) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.view.ViewPager.populate(ViewPager.java:880) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.view.ViewPager$3.run(ViewPager.java:238) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.view.Choreographer$CallbackRecord.run(Choreographer.java:749) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.view.Choreographer.doCallbacks(Choreographer.java:562) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.view.Choreographer.doFrame(Choreographer.java:531) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:735) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.os.Handler.handleCallback(Handler.java:725) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.os.Handler.dispatchMessage(Handler.java:92) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.os.Looper.loop(Looper.java:137) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.app.ActivityThread.main(ActivityThread.java:5237) 05-13 20:48:31.532: E/AndroidRuntime(13219): at java.lang.reflect.Method.invokeNative(Native Method) 05-13 20:48:31.532: E/AndroidRuntime(13219): at java.lang.reflect.Method.invoke(Method.java:511) 05-13 20:48:31.532: E/AndroidRuntime(13219): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:799) 05-13 20:48:31.532: E/AndroidRuntime(13219): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:566) 05-13 20:48:31.532: E/AndroidRuntime(13219): at dalvik.system.NativeStart.main(Native Method) 05-13 20:48:31.532: E/AndroidRuntime(13219): Caused by: java.lang.IllegalArgumentException: Binary XML file line #2: Duplicate id 0x7f040066, tag null, or parent id 0x0 with another fragment for com.google.android.gms.maps.SupportMapFragment 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.support.v4.app.FragmentActivity.onCreateView(FragmentActivity.java:285) 05-13 20:48:31.532: E/AndroidRuntime(13219): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:676) 05-13 20:48:31.532: E/AndroidRuntime(13219): ... 26 more </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.

SQuiL has stopped working due to an internal error.

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