8.4.0 なのに「updating the version of com.google.android.gms to 8.3.0」

このように怒られ,

Execution failed for task ':app:processDebugGoogleServices'. Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 8.3.0.

build.gradle を見ると「8.4.0」

apply plugin: 'com.google.gms.google-services'
...
dependencies {
  ...
  compile 'com.google.android.gms:play-services-gcm:8.4.0'
  ...
}

こんな答えだと.

android - Version conflict updating to 8.4.0 - Stack Overflow

...
dependencies {
  ...
  compile 'com.google.android.gms:play-services-gcm:8.4.0'
  ...
}

// 最終行にもってくる
apply plugin: 'com.google.gms.google-services'

 

まとめ

build.gradle (project-top)

...
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
        classpath 'com.google.gms:google-services:2.0.0-alpha3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
...

build.gradle (app-module)

...
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    ...
    compile 'com.google.android.gms:play-services:8.4.0'
    ...
}
apply plugin: 'com.google.gms.google-services'

おつかれさまでした.

Android Studio 2.0 で「set ANDROID_DAILY_OVERRIDE environment variable to "*****"」

ビルド時に謎のエラーメッセージ.

Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable to "*****"

環境変数「ANDROID_DAILY_OVERRIDE」とか初めて見た.

トップレベルの build.gradle をとりあえず(非推奨だが)書き換えるといける.

dependencies {
    classpath 'com.android.tools.build:gradle:+'
    ....
}

固定で書く場合, 今の最新バージョンはいくつか.

Maven_Repository__com_android_tools_build_»_gradle

Maven Repository: com.android.tools.build » gradle

いや, alpha だし, これか.

com_android_tools_build_gradle

com.android.tools.build.gradle

New_Build_System_-_Android_Tools_Project_Site

New Build System - Android Tools Project Site

エラーメッセージどおりに, OSX なら以下の後, プロジェクトをクリーンして, Android Studio再起動.

launchctl setenv ANDROID_DAILY_OVERRIDE *****

しかし, 引き続き新たなエラーメッセージが...

8.4.0 なのに「updating the version of com.google.android.gms to 8.3.0」


Android 次期バージョン N は Oracle Java を使わないのか?

Diff_-_51b1b6997fd3f980076b8081f7f1165ccc2a4008^__-_platform_libcore_git_-_Git_at_Google

技術ネタ満載の YCombinator の運営する「Hacker News」で昨日から話題になっています.

Google confirms next Android version won’t use Oracle’s proprietary Java APIs | Hacker News

このへん素人目にも想像できるのは「著作権料を払いたくない」という理由.

So in order for Google to avoid paying that royalty going forward they need to move to OpenJDK quickly with their next release, with the belief that using Oracle's GPL JDK implementation also gives them a license to the API (which is somehow separately copyrightable? The Federal Circuit is a mess).

ここらの適用範囲などの法律の話は金額のわりに明快でなく庶民には分かりづらい.

実際, 開発中のソースコードではどのようになってきているのか.

Mysterious Android codebase commit | Hacker News

This diff is more explicit about what's going on:
https://android.googlesource.com/platform/libcore.git/+/aab9...
Change dependency from libart -> libopenjdkjvm.
There are also diffs adding lambda support, tweaking various classes for compatibility with applications that use reflection to access internal capabilities, and fixing lots OpenJDK compatibility bugs.

確かに, OpenJDK に移行してるようにも見えるが.

In the context of the recent juniper attack where some unauthorized code was committed without anybody noticing for years, it seems like it would be easy to hide a backdoor in such a big commit.
How do you go about checking the integrity of the code when you have so many files?
8902 files were changed, most added, and the commit says it's just importing openJDK files. Is there anybody checking that the source file imported haven't been modified to include some kind of backdoor?

はっきり「OpenJDKに移行を進めている」とは言い切れないのか.

WEBでは見づらいのでアプリで.
