Debian Jessie: change MySql distribution to MySql community

Debian Stretch does not shipped MySql. Before upgrade your Debian Jessie into Stretch, you need to change your MySql Debian distribution into MySql Community.

Download MySql apt configuration from https://dev.mysql.com/get/mysql-apt-config_0.8.7-1_all.deb
# wget https://dev.mysql.com/get/mysql-apt-config_0.8.7-1_all.deb
Note: File name may change without notice, check latest mysql-apt-config at https://dev.mysql.com/downloads/repo/apt/

"The MySQL APT repository can only replace distributions of MySQL maintained and distributed by Debian or Ubuntu. It cannot replace any MySQL forks found either inside or outside of the distributions' native repositories. To replace such MySQL forks, you have to uninstall them first before you install MySQL using the MySQL APT repository. Follow the instructions for uninstallation from the forks' distributors and, before you proceed, make sure you back up your data and you know how to restore them to a new server. "

Backup MySql
# mysqldump --all-database > backup_all_201709.sql -u root -p

Remove your MySql Distribution
# apt-get --purge remove mysql-server mysql-client
# apt-get --purge remove mysql-server-5.5 mysql-client-5.5 // if required
# apt-get --purge remove mysql-server-core-5.5 mysql-client-core-5.5
// if required
Note: check your mysql using 

# aptitude search mysql-server

Install MySql apt configuration.
# dpkg -i mysql-apt-config_0.8.7-1_all.deb
Choose MySql 5.7 for stable version and continue by click Ok. It will create apt repository file like this:

# cat /etc/apt/sources.list.d/mysql.list
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out entries below, but any other modifications may be lost.
# Use command 'dpkg-reconfigure mysql-apt-config' as root for modifications.

Android Studio: how to use Google Play service 11.2 release

To use latest Google Play services 11.2 release, we need to meet some requirements.
Here are my environment:
  • Android Studio 2.3.3
  • Android SDK Build-Tools 26.0.1
  • Google Play Service 43
  • Android Support Repository, rev 47
  • Android SDK Platform 26

1. Start from Google Play services 11.2 release, Google Play services dependcies are now abailable via maven.google.com. We need to change our application Grandle build scripts.

  1. Open Tab 1:Project, select Android
  2. Expand Grandle Scripts
  3. Open build.grandle (Project: [your project name])
  4. Find and add google() inside allprojects like this:
allprojects {
  repositories {
    jcenter()
    maven {
      url 'https://dl.google.com/dl/android/maven2/'
      // url 'https://maven.google.com' // NOT WORK
      // Alternative URL is 'https://dl.google.com/dl/android/maven2/'
    }
  }
}

2. Google Play services 11.2 release requires Android SDK Platform 26. You need to install it from SDK Manager and used it.
Open Tab 1:Project, select Android

  1. Expand Grandle Scripts
  2. Open build.grandle (Module: app)
  3. Make sure you use Android SDK Platform 26
android {
  compileSdkVersion 26
  buildToolsVersion "26.0.1"
  defaultConfig {
    ...
    targetSdkVersion 26
    ...
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

3. You can change and use Google Service 11.2 for example to use Google Adsmob
Open Tab 1:Project, select Android

  1. Expand Grandle Scripts
  2. Open build.grandle (Module: app)
dependencies {
  ...
  compile 'com.google.android.gms:play-services-ads:11.2.2'
  ...
}
