Android compile project with target="android-19" failed

Question

Masters,

Recently I am trying to build android project with gradle, and since there one API(@JavascriptInterface annotation) I need to use is only up to api level 17, so I changed my targetAPILevel to 19 in project properties. And it works well when I build the project from Eclipse(Right click on project and Run Android Application).

But when I tried to build the project by gradlew in terminal, it seems it never use target level 19 to build the project. Here is part of the build.gradle file as follow:

android {

// target = 'android-19'
compileSdkVersion 19
buildToolsVersion '19.0.1'

}

Can anyone help me what I did wrong in here, please? Thank you very much.

TargetSdkVersion and compileSdkVersion are different parameters.

In eclipse, you set the target in your Manifest, and set the api used to compile with right click -> properties -> Android Manu.

In your build.gradle you should use something like this:

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }   
}

Hi, Thanks. But I think your way is correct, and mine is correct, too. The only thing I found what will cause the problem is the Proguard. If my build doesn't include proguard, it will run correctly. Don't know what mistake I did in there, will check then. – David_Wang Apr 03 '14 at 05:23
