Android Studio「Instant Run」の適用範囲や条件

実際使ってみると, 編集したコードが反映されたりされなかったり.

でも確かに高速なときもある.

効果的に高速で動作してくれるためのコードの編集範囲・条件は何なのか.

なんだか...

it seems that this feature is not perfectly stable yet : sometimes the modified code is marked as “pushed” whereas the modification is not really applied on the emulator. It is currently stable when it comes to hot resources or xml file swapping. It is really a great improvement, as we generally have to perform numerous incremental builds when we are tuning our xml files.

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...
