Not saving String value in sharedPreferences

I am trying to save a string in sharedPreferences. I don't know what I did wrong but it doesn't save the String value.
this is the code
here I am saving String value "phone". notice its Fragment page

Problem is with different shared preferences objects. According to official documentation:
getPreferences (int mode)
Added in API level 1 Retrieve a SharedPreferences object for accessing
preferences that are private to this activity. This simply calls the
underlying getSharedPreferences(String, int) method by passing in this
activity's class name as the preferences name.
My suggestion is to use special entity for handling shared preferences. In your case it may look like following code
public class SharedPreferencesManager {
private static final String PREFERENCES_NAME = "your_name";//name for xml file
private final SharedPreferences sharedPreferences;
public SharedPreferencesManager(Context context) {
sharedPreferences = context.getSharedPreferences(PREFERENCES_NAME, Context.MODE_PRIVATE);
}
public String getPhone() {
return sharedPreferences.getString("PHONE", null);
}
public void savePhone(#NonNull String phone) {
sharedPreferences.edit().putString("PHONE", phone).apply(); //or commit for blocking save
}
}
Then replace all your direct call to SharedPreferences in Activity, Fragment with above object.

Two activities sending data to each other

Two activities are sending data to each other.
The first activity has a custom list view. The second has one text view and three buttons to increase and decrease a value.
When I click on the first activity, the second activity opens. The second activity increases the text view value and clicked the button. Data goes to the first activity. Same process again.
My problem is that the total value is not displayed in the first activity.
How can i show all increase and decrease values from the second activity in the first activity?

android save contacts and call them

i am programming a little bit android and i have a problem with adding and calling contacts.
my idea was to add two contacts and when the call-button was pressed the user can decide which one he wants to call.. and my two problems are, that on my AVD the code is working until i have to call somebody. so i can choose 2 contacts and these contacts are safed... on the phone of my friend i cant even choose contacts.. the programm just says: "The Application Contacts_SPrefs stopped working"...
well i think there is a problem in my code.. but i dont know where it is and how i could fix it, because in my previous version the code works...
So in this part of the app you can add 2 contacts and choose the button call which opens the other intent which is described below

so.. as you can see.. i dont know really much about the topic Intent and its specifications.. anyway... heres the second part of the app, in which the call-command is.. and this command doesent work either...

Android Voice input without click

I am new to android development. I need a solution for the new app I am developing which takes voice input and gives output in voice by mapping with a mapping database. Current program takes voice input with onlick on button . I need a soultion which can take voice input without clicking of any button simliar to Talking Tom application . Here is my code.My main code is in speakToMe which is method called on onclick & onActivityResult

Voice Recognition not working for talking tom app so you try to use noise detection with sound meter. below here link for voice/ noise detection with audio recording without click.

Please change SoundMeter.java File
mRecorder.setOutputFile(Environment.getExternalStorageDirectory().
getAbsolutePath() + "/test.3ggp");

android crash when trying to get extras.getLong

I have been trying for hours to figure out why android crashes after loading Profile activity. The line that is causing the issue is :
mRowId = extras != null ? extras.getLong(OverLimitDbAdapter.KEY_ROWID): null;
located in Profile.java. so I have firstly
OvertheLimit.java which puts extras via a menu option intent:
package uk.co.obdesign.android.overthelimit;
import android.app.Activity;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.RadioButton;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;
import android.widget.Toast;
public class Overthelimit extends ListActivity {
private OverLimitDbAdapter dbHelper;
private static final int USER_CREATE = 0;
private static final int USER_EDIT = 1;
private Cursor cursor;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.getListView();
dbHelper = new OverLimitDbAdapter(this);
dbHelper.open();
fillData();
registerForContextMenu(getListView());
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
fillData();
}
private void fillData() {
cursor = dbHelper.fetchAllUserDrinks();
startManagingCursor(cursor);
String[] from = new String[] { OverLimitDbAdapter.KEY_USERNAME };
int[] to = new int[] { R.id.label };
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter notes = new SimpleCursorAdapter(this,
R.layout.user_row, cursor, from, to);
setListAdapter(notes);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.profile:
Intent myIntent1 = new Intent(Overthelimit.this, Profile.class);
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID, cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
startActivityForResult(myIntent1, 0);
return true;
case R.id.myusual:
Intent myIntent2 = new Intent(Overthelimit.this, MyUsual.class);
startActivityForResult(myIntent2, 0);
return true;
case R.id.trackme:
Intent myIntent3 = new Intent(Overthelimit.this, TrackMe.class);
startActivityForResult(myIntent3, 0);
return true;
case R.id.moreinfo:
Intent myIntent4 = new Intent(Overthelimit.this, MoreInfo.class);
startActivityForResult(myIntent4, 0);
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onDestroy() {
super.onDestroy();
if (dbHelper != null) {
dbHelper.close();
}
}
}
then selecting the profile menu option takes me to Profile, which crashes trying to get extras.
I have checked data using toast and it's there. any ideas?

Your problem is most likely that you add a String extra (as cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)) returns a String) - but try to get a Long extra - which does not compute.
The following should fix the problem:
mRowId = extras != null ? Long.parseLong( extras.getString(OverLimitDbAdapter.KEY_ROWID) ) : null;

In your Overthelimit class you set the value with the following line:
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID, cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
This puts a String value into the intent extras. Trying to get the same value as a Long value will make you applications crash, as it does not exist as a Long value. If you instead convert the value you get from your cursor object (or gets it directly as a Long from your cursor), your application should not crash anymore. Alternatively, you can get your value from the intent extras by using getString(), not getLong().

I think it giving type casting error as you store the value as string in put try to type cast at putting the value time or get the as string and then convert to long value but for type casting may be you getting type casting error in this so put into the try catch block and see the logcat details to detecting the error
type cast here from string to long or
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID,cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
or get as string here and then type cast from string to long
String s = extras.getString(OverLimitDbAdapter.KEY_ROWID);
mRowId = extras != null ? Long.parseLong(s): null;
