API源碼，另一個重要的學習資料。將其解壓到sources目錄下，最好將其api號標好，比如我這里： ~~~ $ ls sources/ android-14 android-15 android-16 android-17 android-18 android-19 android-21 android-22 ~~~ **3.samples**? 例子是學習的第三個途徑。將其放入samples目錄下即可，如下： ~~~ $ ls samples/ android-10 android-15 android-16 android-17 android-18 android-19 android-5.1 ~~~ **4.platform**? 這是sdk中的核心。將sources-22_r01.zip解壓到platforms目錄，如下： ~~~ $ ls platforms/ android-10 android-14 android-15 android-16 android-17 android-18 android-19 android-21 android-5.1 android-L ~~~ **5.編譯工具**? tools_r24.1.2、build-tools_r22.0.1分別放到tools和build-tools下。? **6.sysimg**? 有了5.1的platform我們就可以開發5.1的應用了，但是我們還缺少一個模擬器。這是sysimg要做的事情。? 將sysimg_arm-22_r01.zip解壓到platform-tools目錄下。 ## 第一個Android5.1例子 build.gradle如下： ~~~ apply plugin: 'com.android.application' android { compileSdkVersion 22 buildToolsVersion "21.1.2" defaultConfig { applicationId "com.linc.testapi22" minSdkVersion 15 targetSdkVersion 22 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:22.+' } ~~~ 演示如下圖：? ![](https://box.kancloud.cn/2016-01-01_5685d198068eb.jpg)? ![](https://box.kancloud.cn/2016-01-01_5685d1981cb2c.jpg)? ![](https://box.kancloud.cn/2016-01-01_5685d19833f50.jpg)? ![](https://box.kancloud.cn/2016-01-01_5685d1985154f.jpg)? ![](https://box.kancloud.cn/2016-01-01_5685d1986e553.jpg) 參考：?
