POWhat is wrong with my ContentProvider in Android 4.3?
text
Body
copied!<p>My app works just fine with any Android version before <code>4.3</code>. I mean when I input a word into <code>edWord</code> (EditText field), a list of similarly-spelled words will appear in the list view.</p> <p>But in <code>Android 4.3</code>, it always returns <code>null</code>, claiming that app_ContentProvider cannot find the supported <code>uri</code>.</p> <p>I use the following code to show the word list:</p> <pre><code>public void showWordlist() { edWord.setEnabled(true); String word = edWord.getText().toString(); Uri uri = Uri.parse("content://doyle.app_name.app_ContentProvider/dict/" + mDBFile.fileName + "/list/" + word); edWord.requestFocus(); try { Cursor result = getContentResolver().query(uri,null,null,null,null); Log.i(MAIN_TAG, "Found word = " + result); //I think the problem lies somewhere here because //the 'result' is always 'null' (see the above log.i) if (result != null) { int countRow=result.getCount(); Log.i(MAIN_TAG, "countRow = " + countRow); mLSTCurrentWord.clear(); //mLSTCurrentContent.clear(); mLSTCurrentWordId.clear(); mAdapter.clear(); if (countRow >= 1) { int indexWordColumn = result.getColumnIndex("word"); int indexIdColumn = result.getColumnIndex("id"); result.moveToFirst(); String strWord; int intId; int i = 0; do { strWord = Utility.decodeContent(result.getString(indexWordColumn)); intId = result.getInt(indexIdColumn); mLSTCurrentWord.add(i,strWord); mLSTCurrentWordId.add(i,intId); //mLSTCurrentContent.add(i,strContent); mAdapter.add(strWord); i++; } while (result.moveToNext()); } result.close(); } lstWord.setAdapter(mAdapter); } catch (Exception ex) { Log.e(MAIN_TAG, "Error = " + ex.toString()); } edWord.setEnabled(true); } </code></pre> <p>And here is my <a href="https://dl.dropboxusercontent.com/u/15034088/Others/Temps/AppProvider.java" rel="nofollow">app_ContentProvider</a>.</p> <p>I have no idea whether there are any changes in <code>Android 4.3</code> that stop my app from functioning normally.</p> <p>Regarding my code lines above, can you please tell me what the problem might be? Thanks a lot.</p>
