    <p>I m using read &amp; write string to internal memory. My <strong>"WriteFavData"</strong> is working fine. But In <strong>"ReadFavData"</strong> is not working. Actually when i reach the line <strong>if(favFile.exists())</strong> in ReadFavData(..,..), it says file not found &amp; execute the else part. I have already check the emulator internal memory using command line shell access <strong>adb shell cat /data/data/com.android.mypackage/files/fav_data_channel</strong>, the file is there. Why is saying file is not present.? Any ideas....</p> <pre><code> public boolean ReadFavData(Context context, String channelName) { boolean isFileFound = false; FileInputStream fin ; StringBuffer strContent = new StringBuffer(""); String fileName = FAV_FILE_NAME + "_" + channelName; File favFile = new File(fileName); int ch; if(favFile.exists()) { isFileFound = true; try { fin = context.openFileInput(FAV_FILE_NAME + "_" + channelName); isFileFound = true; while ((ch = fin.read()) != -1) { strContent.append((char) ch); } fin.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } else { Log.i(TAG, "not found"); } return isFileFound; } public boolean WriteFavData(Context context, String channelName) { String favStr; FileOutputStream fos ; JSONObject videos = new JSONObject(); videos.put("videos", favJsonArray); String favStr = videos.toJSONString(); //note.toString(); String fileName = FAV_FILE_NAME + "_" + channelName; File f = new File(fileName); if(f.exists()) { Log.i("Old FIle", "Found"); f.delete(); } if(f.exists()) Log.i("Still", "Exist"); try { fos = context.openFileOutput(FAV_FILE_NAME + "_" + channelName, Context.MODE_PRIVATE); fos.write(favStr.getBytes()); fos.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return true; } </code></pre> <p>Actually, i debugged again &amp; track that on line <strong>if(file.exists())</strong>, the file is not present.. But if i comment this line &amp; read my file directly, i m able to read file successfully. Whats wrong with <strong>if(file.exists())</strong>?</p>

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.
