How to change target build on Android project?

Question

I currently have an Android project in Eclipse.

I created it with a target build of 1.5 (sdk 3).

Now I want to change it so that it has a minSdk of 3 and tar

Answer 1

as per 2018, the targetSdkVersion can be set up in your app/build.gradle the following way:

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'

    defaultConfig {
       ...
       targetSdkVersion 26
    }
    ...
}

if you choose 26 as SDK target, be sure to follow https://developer.android.com/about/versions/oreo/android-8.0-migration
