Question

我尝试从源代码添加Android库，如接受的答案所示：

Adding Library Source into Android Studio

我在build.gradle文件中收到错误：

错误：（4,0）无法为org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler类型的对象获取未知属性'supportLibVersion'。

这是我的build.gradle文件：

public class SplashActivity extends Activity {

  private static final String TAG = "SplashActivity";
  private static final boolean DO_XML = false;

  private ViewGroup mMainView;
  private SplashView mSplashView;
  private View mContentView;
  private Handler mHandler = new Handler();

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // change the DO_XML variable to switch between code and xml
    if(DO_XML==true){
      // inflate the view from XML and then get a reference to it

    } else {
      Log.d("Main","end now");
      // create the main view and it will handle the rest
      mMainView = new MainView(getApplicationContext());
      mSplashView = ((MainView) mMainView).getSplashView();
      setContentView(mMainView);
    }

    // pretend like we are loading data
    startLoadingData();
  }

  private void startLoadingData(){
    // finish "loading data" in a random time between 1 and 3 seconds
    Random random = new Random();
    mHandler.postDelayed(new Runnable(){
      @Override
      public void run(){
        onLoadingDataEnded();


      }
    }, 1000 + random.nextInt(2000));

  }

  private void onLoadingDataEnded(){

    // now that our data is loaded we can initialize the content view
    // add the content view to the background
    Context context = getApplicationContext();



    // add the content view to the background

    mSplashView.splashAndDisappear(new ISplashListener(){
      @Override
      public void onStart(){
        // log the animation start event
        if(BuildConfig.DEBUG){
          Log.d(TAG, "splash started");
        }
      }

      @Override
      public void onUpdate(float completionFraction){
        // log animation update events
        if(BuildConfig.DEBUG){
          Log.d(TAG, "splash at " + String.format("%.2f", (completionFraction * 100)) + "%");
        }
      }

      @Override
      public void onEnd(){
        // log the animation end event
        if(BuildConfig.DEBUG){
          Log.d(TAG, "splash ended");
        }
        // free the view so that it turns into garbage
        mSplashView = null;

        if(!DO_XML){
          // if inflating from code we will also have to free the reference in MainView as well
          // otherwise we will leak the View, this could be done better but so far it will suffice
          ((MainView) mMainView).unsetSplashView();

        }

      }


    });

  }
}

我可以看到该库有一个名为dependencies.gradle的文件，其中包含以下内容：

apply plugin: 'com.android.library'

dependencies {
    compile "com.android.support:support-annotations:${supportLibVersion}"
    compile "com.android.support:support-v4:${supportLibVersion}"
    compile "com.android.support:design:${supportLibVersion}"
    compile rootProject.ext.dep.timber
    compile rootProject.ext.dep.okhttp3
    compile rootProject.ext.dep.lost
...

看来这是定义属性的地方，但我认为在构建过程中没有看到它。 dependencies.gradle比build.gradle文件高一级，这可以解释为什么在导入Gradle项目后看不到该属性。可以在以下位置找到原始库源：

source library folder

解决此问题的最佳方法是什么？

由于

米奇

缺少Android supportLibVersion库依赖项
