android studio 初探

將以前的項目轉成Android studio，導入後，遇到一堆問題，真有點(ˇˍˇ） 想～放棄as了，編譯要3到四分鐘，跟eclipse性能比起來真得是差太多了。是不是as的語法檢測等限制的太多了，build完後就崩潰了，在eclipse跑的好好的項目，在as上跑出來幾百個error！瞬間蒙逼！

---

1、build tool 和 sdk 版本不一致，as自動識別並下載

2、drawable-hdpi的圖片資源不是標準的.9的，看下面報的錯誤，找到相關圖片，改成合法的。

Error:Execution failed for task ':yr_library:mergeDebugAndroidTestResources'.
> Error: java.lang.RuntimeException: Crunching Cruncher imcc_from_server.9.png failed, see logs

3、 AS的Gradle插件默認會啓用Manifest Merger Tool，若Library項目中也定義了與主項目相同的屬性（例如默認生成的android:icon和android:theme），則此時會合並失敗，並報下面的錯誤。

解決辦法：

方法1：在Manifest.xml的application標籤下添加tools:replace=”android:icon, android:theme”（多個屬性用,隔開，並且記住在manifest根標籤上加入xmlns:tools=”http://schemas.android.com/tools”，否則會找不到namespace哦）

方法2：在build.gradle根標籤上加上useOldManifestMerger true （懶人方法）

參考官方介紹：

http://tools.android.com/tech-docs/new-build-system/user-guide/manifest-merger

Error:(26, 9) Attribute application@icon value=(@drawable/logo) from AndroidManifest.xml:26:9

Error:(28, 9) Attribute application@theme value=(@style/ThemeActionBar) from AndroidManifest.xml:28:9
is also present at XXXX-trunk:XXXXLib:unspecified:15:9 value=(@style/AppTheme)
Suggestion: add ‘tools:replace=”android:theme”‘ to <application> element at AndroidManifest.xml:24:5 to override
Error:Execution failed for task ‘:XXXX:processDebugManifest’.

> Manifest merger failed with multiple errors, see logs

4、當Android Studio中編譯java方面的代碼，出現類似的警告:

有關詳細信息, 請使用 -Xlint:deprecation 重新編譯。
有關詳細信息, 請使用 -Xlint:unchecked 重新編譯。
時，去項目對應的build.gradle中添加配置:

allprojects {
    repositories {
        jcenter()
    }
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation"
        }

    }
}

即可消除警告。

爲什麼這麼麻煩！！！還有無數問題。。。
