SDK directory structure

:/opt/sdk$ lsadd-ons  build-tools  docs extras  platforms  platform-tools  samples  sources  system-images  temp  tmp  tools

1. docs
Just rename the original docs directory, such as a docs-21, and unzip the latest docs-22. Documents are an important way to learn about the new feature of Android.
2. sources
API source code, another important learning material. Decompress it to the sources directory. It is best to mark its api number, for example, here:

$ ls sources/android-14  android-15  android-16  android-17  android-18  android-19  android-21  android-22

3. samples
The example is the third way to learn. Put it in the samples directory, as shown below:

$ ls samples/android-10  android-15  android-16  android-17  android-18  android-19  android-5.1

4. platform
This is the core of the sdk. Decompress sources-22_r01.zip to the platforms directory, as shown below:

$ ls platforms/android-10  android-14  android-15  android-16  android-17  android-18  android-19  android-21  android-5.1  android-L

5. Compilation tools
Tools_r24.1.2 and build-tools_r22.0.1 are placed under tools and build-tools respectively.
6. sysimg
With the 5.1 platform, we can develop 5.1 applications, but we still lack a simulator. This is what sysimg wants to do.
Extract sysimg_arm-22_r01.zip to the platform-tools directory.

First Android5.1 example

Build. gradle is as follows:

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.+'}
