Solución a cannot connect to MySQL 4.1+ using the old insecure authentication.

How to solve that? /Como resolver ?

SQLSTATE[HY000] [2000] mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file 

1- Go to file my.ini (windows) or my.cnf (linux), and go to the line / Ve al archivo my.cnf en linux o a my.ini en windos:

[mysqld]

Set old_passwords to false belongs to the mysqld section, if you can't find it there, just add it:[mysqld]
old_passwords = 0

2- Restart you server/ Reinicia tu servidor.

3-Run that comand / Corre el siguiente comando:

mysql> SHOW VARIABLES LIKE 'old_passwords'

+---------------+-------+| Variable_name | Value |+---------------+-------+| old_passwords | OFF |+---------------+-------+

And old_passwords must appear like OFF.

4-Update your users passwords with :

UPDATE mysql.user SET password= PASSWORD(¨NEW PASSWORD¨);

And you password must look like :

Android studio Loadings

A best option for show Loading in your app is : AVLoadingIndicatorView

https://github.com/81813780/AVLoadingIndicatorView

Usage

Step 1

Add dependencies in build.gradle.

    dependencies {
       compile 'com.wang.avi:library:2.1.3'
    }

Step 2

Add the AVLoadingIndicatorView to your layout:

Simple

    <com.wang.avi.AVLoadingIndicatorView
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"
        app:indicatorName="BallPulseIndicator"
        />

Advance

    <com.wang.avi.AVLoadingIndicatorView
        android:id="@+id/avi"
        android:layout_width="wrap_content"  //or your custom size
        android:layout_height="wrap_content"  //or your custom size
        style="@style/AVLoadingIndicatorView"// or AVLoadingIndicatorView.Large or AVLoadingIndicatorView.Small
        android:visibility="visible"  //visible or gone
        app:indicatorName="BallPulseIndicator"//Indicator Name
        app:indicatorColor="your color"
        />

Step 3

It's very simple use just like .

   void startAnim(){
        avi.show();
        // or avi.smoothToShow();
   }

   void stopAnim(){
        avi.hide();
        // or avi.smoothToHide();
   }

An example of Android Sharedpreferences.

An example of Android Sharedpreferences.

Configurando valores en Preferencia /Setting values in Preference:

// My preferencia Nombre / MY_PREFerence_NAME - : 
//public static final String MY_PREFS_NAME = "MyPrefsFile";
 SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE).edit();
 editor.putString("name", "Elena");
 editor.putInt("idName", 12);
 editor.commit();

Retrieve data from preference:

SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE); 
String restoredText = prefs.getString("text", null);
if (restoredText != null) {
  String name = prefs.getString("name", "No name defined");//"No name defined" is the default value.
  int idName = prefs.getInt("idName", 0); //0 is the default value.
}

Android Studio Home Button in ToolBar / Andorid Studio Home Button en Toolbar

En este tutorial les enseñaré como activar en el toolbar la flecha de atrás, o Home button. Lo primero que tenemos que tener es un toolbar en nuestra vista:

<android.support.design.widget.AppBarLayout

<android.support.v7.widget.Toolbar

Quedando mi código de esta manera:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".Activities.Galeria">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_uniformes" />

</android.support.design.widget.CoordinatorLayout>

En nuestra activity inicializamos el nuestra barra:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

setSupportActionBar(toolbar);

Con la siguiente sentencia habilitamos el botón:

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

getSupportActionBar().setDisplayShowHomeEnabled(true);

Seguidamente habilitamos el listener para realizar una acción en caso de ser presionado:

toolbar.setNavigationOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View view) {

        //la acción de desees

    }

});
