Android Studio: How to debug older version of Android SDK step-by-step

I can not confirm my answer works, but it is working for me.

I replace my compileSdkVersion, buildToolsVersion, minSdkVersion and targetSdkVersion with new one like following in my build.gradle file.

android {
      compileSdkVersion 22
      buildToolsVersion "22.0.1"


defaultConfig {
    applicationId "com.example.mytest"
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),  'proguard-rules.pro'
         }  
   }
}

After changing it, you may not need to convert old to new or new to old sdk component.
