    text
    copied!<p>I have a weird problem with listview, while using simplecursor adapter. Here is the error</p> <pre><code>08-31 21:50:14.540: INFO/dalvikvm(12195): Uncaught exception thrown by finalizer (will be discarded): 08-31 21:50:14.540: INFO/dalvikvm(12195): java.lang.IllegalStateException: Binder has been finalized! 08-31 21:50:14.540: INFO/dalvikvm(12195): at android.os.BinderProxy.transact(Native Method) 08-31 21:50:14.540: INFO/dalvikvm(12195): at android.database.BulkCursorProxy.close(BulkCursorNative.java:289) 08-31 21:50:14.540: INFO/dalvikvm(12195): at android.database.BulkCursorToCursorAdaptor.close(BulkCursorToCursorAdaptor.java:141) 08-31 21:50:14.540: INFO/dalvikvm(12195): at android.database.CursorWrapper.close(CursorWrapper.java:43) 08-31 21:50:14.540: INFO/dalvikvm(12195): at android.content.ContentResolver$CursorWrapperInner.close(ContentResolver.java:1575) 08-31 21:50:14.540: INFO/dalvikvm(12195): at android.content.ContentResolver$CursorWrapperInner.finalize(ContentResolver.java:1586) 08-31 21:50:14.540: INFO/dalvikvm(12195): at dalvik.system.NativeStart.run(Native Method) </code></pre> <p>I have runQueryOnBackgroundThread implemented in my cursorAdapter, which is invoked by the Filter.filter method call from the activity. So I dont have any reference of the cursor in my activity. Everytime I query I understand I get cursor changed callback in my cursor adapter, which extends SimpleCursorAdapter</p> <p>Here is how it looks</p> <pre><code>public void changeCursor(Cursor cursor) { Log.d(TAG, "Cursor changed ... **************** "+ cursor); if (cursor != null) { setLoading(false); } super.changeCursor(cursor); initSectionHeaders(cursor); notifyDataSetChanged(); } </code></pre> <p><code>runQueryOnBackgroundThread()</code> just returns a cursor from a query.</p> <p>Am I missing something, should the cursor be closed or managed anywhere? Any help on the leads would greatly help. Thanks in advance.</p> <p><em><strong></em>**UPDATE*<em>*</em></strong> Snippets of my adapter </p> <pre><code>public Cursor runQueryOnBackgroundThread(CharSequence constraint) { Log.d(TAG, "runQueryOnBackgroundThread "+ constraint); if (getFilterQueryProvider() != null) { return getFilterQueryProvider().runQuery(constraint); } return doQuery(constraint, People.CONTENT_URI); } private Cursor doQuery(CharSequence constraint, Uri queryUri){ StringBuilder selectionStrBuilder = new StringBuilder(); String selectionArgs[] = null; String selection = null; if(constraint!=null){ //ADDING GLOB so that the sql query can interpret linux style wildcards selectionStrBuilder.append("(UPPER(").append(People.DISPLAY_NAME).append(") GLOB ?)"); selection = selectionStrBuilder.toString(); String constraintStr = constraint.toString().toUpperCase(); //prepend and append '*' - TODO improve constraintStr = "*"+ constraintStr; constraintStr +="*"; selectionArgs = new String[]{constraintStr}; } ContentResolver contentRes = context.getContentResolver(); return contentRes.query(queryUri, null, selection, selectionArgs, People.DISPLAY_NAME); } </code></pre> <p>Other than these two functions I have changeCursor overridden as posted earlier and use the cursor in bind view to get the data. I don't close or modify cursor properties anywhere else. </p> <p>My provider getQuery function looks like</p> <pre><code>SQLiteDatabase db = dbHelper.getReadableDatabase(); Cursor c = qb.query(db, projection, selection, selectionArgs, null, null, orderBy); // Tell the cursor what uri to watch, // so it knows when its source data changes c.setNotificationUri(getContext().getContentResolver(), uri); return c; </code></pre> <p><strong>UPDATE2*</strong></p> <p>When I run the same program on the emulator I get this stack trace, which is very different from what I see on the tablet.</p> <pre><code>01-03 17:21:44.130: ERROR/IMemory(9328): binder=0x3891a0 transaction failed fd=-2147483647, size=0, err=-2147483646 (Unknown error: 2147483646) 01-03 17:21:44.130: ERROR/IMemory(9328): cannot dup fd=-2147483647, size=0, err=-2147483646 (Bad file number) 01-03 17:21:44.130: ERROR/IMemory(9328): cannot map BpMemoryHeap (binder=0x3891a0), size=0, fd=-1 (Bad file number) 01-03 17:21:44.130: WARN/dalvikvm(9328): JNI WARNING: JNI method called with exception raised 01-03 17:21:44.130: WARN/dalvikvm(9328): in Ldalvik/system/NativeStart;.run ()V (CallStaticVoidMethodV) 01-03 17:21:44.130: WARN/dalvikvm(9328): Pending exception is: 01-03 17:21:44.130: INFO/dalvikvm(9328): Ljava/lang/RuntimeException;: No memory in memObj 01-03 17:21:44.130: INFO/dalvikvm(9328): at android.database.CursorWindow.native_init(Native Method) 01-03 17:21:44.130: INFO/dalvikvm(9328): at android.database.CursorWindow.&lt;init&gt;(CursorWindow.java:518) 01-03 17:21:44.130: INFO/dalvikvm(9328): at android.database.CursorWindow.&lt;init&gt;(CursorWindow.java:27) 01-03 17:21:44.130: INFO/dalvikvm(9328): at android.database.CursorWindow$1.createFromParcel(CursorWindow.java:493) 01-03 17:21:44.130: INFO/dalvikvm(9328): at android.database.CursorWindow$1.createFromParcel(CursorWindow.java:491) 01-03 17:21:44.130: INFO/dalvikvm(9328): at android.content.ContentProviderNative.onTransact(ContentProviderNative.java:103) 01-03 17:21:44.130: INFO/dalvikvm(9328): at android.os.Binder.execTransact(Binder.java:320) 01-03 17:21:44.130: INFO/dalvikvm(9328): at dalvik.system.NativeStart.run(Native Method) 01-03 17:21:44.130: INFO/dalvikvm(9328): "Binder Thread #3" prio=5 tid=9 NATIVE 01-03 17:21:44.130: INFO/dalvikvm(9328): | group="main" sCount=0 dsCount=0 obj=0x405de828 self=0x8e288 01-03 17:21:44.130: INFO/dalvikvm(9328): | sysTid=9336 nice=0 sched=0/0 cgrp=[fopen-error:24] handle=959480 01-03 17:21:44.130: INFO/dalvikvm(9328): at dalvik.system.NativeStart.run(Native Method) 01-03 17:21:44.130: ERROR/dalvikvm(9328): VM aborting </code></pre> <p>And Crashes the application. </p> <p>I found a bug report on this issue <a href="http://code.google.com/p/android/issues/detail?id=10614" rel="nofollow" title="Click for bug report">here</a> </p> <p>Anyone faced the same problem?
