Hi, All I have developing one application in that I am sending
contacts to server and restoring them back to mobile. I have stored
contacts to server successfully but there is problem in restoring them
back to mobile. One of my method throws NullPointerException while
restoring. The method is
public void doImport(final String fileName, final boolean replace,
final App app) {
try {
System.out.println ("Inside try block of doImport ()
method");
vcfFile = new File(fileName);
System.out.println ("After creating file");
final BufferedReader vcfBuffer = new
BufferedReader(new FileReader(vcfFile));
System.out.println ("Before calculating
size");
final long maxlen = vcfFile.length();
System.out.println ("%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%"+maxlen);
// Start lengthy operation in a background thread
new Thread(new Runnable() {
public void run() {
long importStatus = 0;
synchronized (syncMonitor) {
mAction = Action.IMPORT;
syncFileName = fileName;
}
showNotification();
SQLiteDatabase db =
mOpenHelper.getWritableDatabase();
SQLiteStatement querySyncId =
db.compileStatement("SELECT " + SYNCID + " FROM " +
SYNCDATA_TABLE_NAME + " WHERE " + PERSONID + "=?");
System.out.println
("****"+querySyncId.getUniqueId());
SQLiteStatement queryPersonId =
db.compileStatement("SELECT " + PERSONID + " FROM " +
SYNCDATA_TABLE_NAME + " WHERE " + SYNCID + "=?");
System.out.println
("****"+queryPersonId.getUniqueId());
SQLiteStatement insertSyncId =
db.compileStatement("INSERT INTO " + SYNCDATA_TABLE_NAME + " (" +
PERSONID + "," + SYNCID + ") VALUES (?,?)");
System.out.println
("****"+insertSyncId.getUniqueId());
Contact parseContact = new
Contact(querySyncId, queryPersonId, insertSyncId);//Iam getting
parseContact as a null
try {
long ret = 0;
do {
System.out.println ("Inside
do");
System.out.println
("**************"+parseContact.firstName);
System.out.println
("**************"+parseContact.emails);
System.out.println
("________________"+parseContact.displayName);
System.out.println
("******************"+parseContact.notes);
System.out.println
("************************"+vcfBuffer.read());
ret =
parseContact.parseVCard(vcfBuffer);
if (ret >= 0) {
parseContact.addContact(getApplicationContext(), 0, replace);
importStatus
+= parseContact.getParseLen();
// Update the
progress bar
app.updateProgress((int) (100 *
importStatus / maxlen));
}
} while (ret > 0);
db.close();
app.updateProgress(100);
synchronized (syncMonitor) {
mAction = Action.IDLE;
showNotification();
}
stopSelf();
} catch (IOException e) {
}
}
}).start();
} catch (FileNotFoundException e) {
app.updateStatus("File not found: " +
e.getMessage());
}
}
LogCat generates following error message
