Android build時にapkにcommitHashを埋め込んでアプリ上で確認する #Android

自分用メモ

/app/build.gradle

//commit hash 取得
def getCommitHasH() {
    def process = "git rev-parse --short HEAD".execute()
    process.waitFor()
    (process.exitValue() == 0) ? process.text.trim() : ""
}

android {
    defaultConfig {
        // BuildConfig へ埋め込み
        buildConfigField("String", "COMMIT_HASH", "\"" + getCommitHasH() + "\"")
    }
}

kotlinで表示制御する場合
HogeActivity.kt

//debugビルドなら表示する
if(BuildConfig.DEBUG){
  commitHashText.text = BuildConfig.COMMIT_HASH
  commitHashText.visibility = View.VISIBLE
}else{
  commitHashText.visibility = View.GONE
}

layoutxmlで表示制御する場合

<!-- import BuildConfig -->
<data>
    <import type="com.hoge.BuildConfig"/>
</data>

<!-- Data binding -->
<TextView
    tools:text="@{BuildConfig.COMMIT_HASH}"
    android:visibility="@{BuildConfig.DEBUG ? View.VISIBLE : View.GONE}"
/>
