Deleting a file and delete its name from a list

I am trying to delete files from a list view, I am able to delete the original file but not to delete the name from the list, I think its because I need to delete it from the database, problem is I don't know how, could somebody help?
// the adapter
listAdapter = new ArrayAdapter<String>(RecordsActivity.this, R.layout.support_simple_spinner_dropdown_item, MainActivity.listRecord);
recordList.setAdapter(listAdapter);
//deleting the file (which goes well, the name is not deleted from the database I guess)
delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try {
datadelete(filePath);
listAdapter.remove(recordToPlay);
listAdapter.notifyDataSetChanged();
delete.setVisibility(View.INVISIBLE);
share.setVisibility(View.INVISIBLE);
Toast.makeText(getApplicationContext(), "File deleted successfully", Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
});
// The dataDelete method
public void dataDelete(String inputPath) throws FileNotFoundException {
try {
// delete the original file
new File(inputPath).delete();
} catch (Exception e) {
Log.e("tag", e.getMessage());
}
}
//Main Activity
File directory = new File(Environment.getExternalStorageDirectory() + File.separator + "/Recordings");
directory.mkdirs();
//outPutFile = Environment.getExternalStorageDirectory().toString() + "/recording.3gp";
String dateTime = new SimpleDateFormat("dd.MM.yyyy hh-mm-ss aa", Locale.getDefault()).format(new Date());
//Date date = new Date();
//String dateTime = DateFormat.getDateTimeInstance().format(date);
outPutFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Recordings/"+dateTime +".m4a";
final String DIR_DATABASE = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Recordings";
String sqliteQuery = "CREATE TABLE IF NOT EXISTS Recordings (ID INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL UNIQUE , fileName VARCHAR)";
database = SQLiteDatabase.openOrCreateDatabase(DIR_DATABASE + "db.sqlite", null);
database.execSQL(sqliteQuery);
getNames();
// The getNames method for retrieving the names of the files
public static void getNames(){
Cursor cursor = database.rawQuery("SELECT fileName FROM Recordings", null);
ArrayList<String> fileNames = new ArrayList<>();
while (cursor.moveToNext()) {
String fileName = cursor.getString(0);
fileNames.add(fileName);
}
cursor.close();
database.close();
listRecord.addAll(fileNames);
}
// And this is where I save the files
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mediaRecorder.stop();
mediaRecorder.release();
mediaRecorder = null;
stop.setEnabled(false);
pauseBtn.setEnabled(false);
SQLiteDatabase database = SQLiteDatabase.openDatabase(DIR_DATABASE + "db.sqlite", null, 0);
values = new ContentValues();
values.put("fileName", outPutFile.substring(31));
database.insert("Recordings", "", values);
Toast.makeText(getApplicationContext(), "Audio recorded", Toast.LENGTH_LONG).show();
Activity mActivity = MainActivity.this;
restartActivity(mActivity);
}
});

You should add a delete query to delete data from the database. Change your code in to
delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try {
datadelete(filePath);
database = this.getWritableDatabase();
database.execSQL("DELETE FROM Recordings WHERE fileName = '"+your file name Here+"'");
database.close();
listAdapter.remove(recordToPlay);
listAdapter.notifyDataSetChanged();
delete.setVisibility(View.INVISIBLE);
share.setVisibility(View.INVISIBLE);
Toast.makeText(getApplicationContext(), "File deleted successfully", Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
});
You should write the filename which you want to delete in the sqlite query. Hope this will work.

get path of video file selected from gallery getting NULL. How to get path of video file?

get path of video file selected from gallery getting NULL. How to get path of video file ? Get URi in Activity Result also give null. converting Uri to String also getting Null.
Intent intent;
String selectedVideo1Path, selectedVideo2Path;
EditText e1,e2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.videos_activity);
Button button1 = (Button) findViewById(R.id.video1_btn);
Button button2 = (Button) findViewById(R.id.video2_btn);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectVideoFromGallery();
startActivityForResult(intent, 101);
}
});
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
selectVideoFromGallery();
startActivityForResult(intent, 102);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 101) {
if (data.getData() != null) {
selectedVideo1Path = getPath(data.getData());
Toast.makeText(MergeVideosActivity.this, "Path 1 : "+selectedVideo1Path, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "Failed to select video", Toast.LENGTH_LONG).show();
}
}
if (requestCode == 102) {
if (data.getData() != null) {
selectedVideo2Path = getPath(data.getData());
//String str2 = selectedVideo2Path.toString();
// e2.setText(str2);
Toast.makeText(MergeVideosActivity.this, "Path 2 : "+selectedVideo2Path, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "Failed to select video", Toast.LENGTH_LONG).show();
}
}
}
This is my getPath method
public String getPath(Uri uri) {
int column_index = 0;
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery(uri, projection, null, null, null);
if (cursor != null) {
column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
cursor.moveToFirst();
}
return cursor.getString(column_index);
}
Selected Video from Gallery I hope its OK ? Check it
public void selectVideoFromGallery() {
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)) {
intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
} else {
intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Video.Media.INTERNAL_CONTENT_URI);
}
intent.setType("video/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
}
}

Update your getPath method
public String generatePath(Uri uri,Context context) {
String filePath = null;
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
if(isKitKat){
filePath = generateFromKitkat(uri,context);
}
if(filePath != null){
return filePath;
}
Cursor cursor = context.getContentResolver().query(uri, new String[] { MediaStore.MediaColumns.DATA }, null, null, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
filePath = cursor.getString(columnIndex);
}
cursor.close();
}
return filePath == null ? uri.getPath() : filePath;
}
#TargetApi(19)
private String generateFromKitkat(Uri uri,Context context){
String filePath = null;
if(DocumentsContract.isDocumentUri(context, uri)){
String wholeID = DocumentsContract.getDocumentId(uri);
String id = wholeID.split(":")[1];
String[] column = { Media.DATA };
String sel = Media._ID + "=?";
Cursor cursor = context.getContentResolver().
query(Media.EXTERNAL_CONTENT_URI,
column, sel, new String[]{ id }, null);
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex);
}
cursor.close();
}
return filePath;
}

How to add all phone contacts in Sqlite database?

Database code is as follows:
public void Insert_phone_contact(String [] contact){
try{

for(int i=0;i<contact.length;i++){
// put all values in ContentValues

DB.insert(TABLE_CONTACTS, null, cv);
}// insert in db
}
DB.close(); // call close
}
catch(Exception ex){

}
}
i want to add all contacts to database when i click "tv_restore_contacts" .But i am getting NullPointerException. I don't know where i am wrong?
logcat Error stack is java.lang.NullPointerException.

Use the following code to grab the contacts & return them to a list datatype to save them whole list in a db or open a DB connection inside the method and do sql insert statements on each contact object you wish to store. N/B The Contacts API is deprecated be sure to use ContactsContract Api.
Private void getDetails(){
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER };
Cursor names = getContentResolver().query(uri, projection, null, null, null);
int indexName = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int indexNumber = names.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
names.moveToFirst();
do {
String name = names.getString(indexName);
Log.e("Name new:", name);
String number = names.getString(indexNumber);
Log.e("Number new:","::"+number);
} while (names.moveToNext());
}

SQLite in Android: do I have to download any SQLite Administration (like MySQL) or it is already in device memory?

I need to work with SQLite in Android.
So, do I have to download any SQLite Administration (like MySql) or it is already in device memory?

All you need is already installed. To inspect the database during development you can use the sqlite3 tool. It is installed in the emulator.

You Don't need to download anything.its already there.

You don't have to do anything besides using the built-in tools in the Android SDK. For more information please have a look at the sqlite documentation
Basically you can use Java code to create databases, insert records into them, modify them etc.
If you want a graphical way to work on the databases, simply use Eclipse's DDMS View to navigate into your app's databases folder. From there, download the database on your computer and open it with one of the many sqlite applications available.

Trying to insert contact into edittext using contact picker

I'm trying to allows user to insert their number using a contact picker in android. I am currently using the example from post 2 in Getting Number from Contacts Picker the contact picker appears and so but when i select a contact the contact number doesn't affect inside my edittext.
There's no logcat error or whatsoever.
My code:
public void doLaunchContactPicker(View view) {
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
Contacts.CONTENT_URI);
startActivityForResult(contactPickerIntent, CONTACT_PICKER_RESULT);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
switch (requestCode) {
case CONTACT_PICKER_RESULT:
Cursor cursor = null;
String phoneNumber = "";
List<String> allNumbers = new ArrayList<String>();
int phoneIdx = 0;
try {
Uri result = data.getData();
String id = result.getLastPathSegment();
cursor = getContentResolver().query(Phone.CONTENT_URI, null, Phone.CONTACT_ID + "=?", new String[] { id }, null);
phoneIdx = cursor.getColumnIndex(Phone.DATA);
if (cursor.moveToFirst()) {
while (cursor.isAfterLast() == false) {
phoneNumber = cursor.getString(phoneIdx);
allNumbers.add(phoneNumber);
cursor.moveToNext();
}
} else {
//no results actions
}
} catch (Exception e) {
//error actions
} finally {
if (cursor != null) {
cursor.close();
}
final EditText phoneInput = (EditText) findViewById(R.id.mobileno);
final CharSequence[] items = allNumbers.toArray(new String[allNumbers.size()]);
AlertDialog.Builder builder = new AlertDialog.Builder(SIMMessageSenderActivity.this);
builder.setTitle("Choose a number");
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
String selectedNumber = items[item].toString();
selectedNumber = selectedNumber.replace("-", "");
phoneInput.setText(selectedNumber);
}
});
AlertDialog alert = builder.create();
if(allNumbers.size() > 1) {
alert.show();
} else {
String selectedNumber = phoneNumber.toString();
selectedNumber = selectedNumber.replace("-", "");
phoneInput.setText(selectedNumber);
}
if (phoneNumber.length() == 0) {
//no numbers found actions
}
}
break;
}
} else {
//activity result error actions
}
}

This below code is one I am using and it is working pretty fine for me. Try this one.
if((requestCode == PICK_CONTACT) && (resultCode == RESULT_OK))
{
if (data != null) {
Uri contactData = data.getData();
try {
String id = contactData.getLastPathSegment();
String[] columns = {Phone.DATA,Phone.DISPLAY_NAME};
Cursor phoneCur = getContentResolver()
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
columns ,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id },
null);
final ArrayList<String> phonesList = new ArrayList<String>();
String Name = null ;
if(phoneCur.moveToFirst())
{
do{
Name = phoneCur.getString(phoneCur.getColumnIndex(Phone.DISPLAY_NAME));
String phone = phoneCur
.getString(phoneCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA));
phonesList.add(phone);
} while (phoneCur.moveToNext());
}
phoneCur.close();
if (phonesList.size() == 0) {
Toast.makeText(
this,"This contact does not contacin any number",
Toast.LENGTH_LONG).show();
} else if (phonesList.size() == 1) {
toET.setText(phonesList.get(0));
} else {
final String[] phonesArr = new String[phonesList
.size()];
for (int i = 0; i < phonesList.size(); i++) {
phonesArr[i] = phonesList.get(i);
}
AlertDialog.Builder dialog = new AlertDialog.Builder(
MessageManagerActivity.this);
dialog.setTitle("Name : "+Name);
((Builder) dialog).setItems(phonesArr,
new DialogInterface.OnClickListener() {
public void onClick(
DialogInterface dialog,
int which) {
String selectedEmail = phonesArr[which];
toET.setText(selectedEmail);
}
}).create();
dialog.show();
}
} catch (Exception e) {
Log.e("FILES", "Failed to get phone data", e);
}
}
}
Create your edittext as a class variable.. so you can also apply a empty check, I am very much sure you are creating it again for that purpose..
