Android external library

Question

I would like to create such as "Common" library for android, but I have problems with configuring it in Intellij IDEA.

Let's say, what I would like to have ActivityHelper class which looks like this:

import android.app.Activity;
import android.view.Window;
import android.view.WindowManager;

public class ActivityHelpers
{
    public static void unlockScreen(Activity activity)
    {
        Window window = activity.getWindow();
        window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
        window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
        window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
    }

    public static void clearFlags(Activity activity)
    {
        Window window = activity.getWindow();
        window.clearFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
        window.clearFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
        window.clearFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
    }
}

I added new module, "Gradle: Java Library" under Android section, then set up Android API 19 Platform as Module SDK in Modules settings.

Looks like editor can see import android.app.Activity; , but compilation fails with:

Error:(3, 19) Gradle: error: package android.app does not exist

etc.

Can it be done somehow?

Answer 1

创建模块时，请寻找“ Android库”模块而不是“ Java库”模块。

You can create library project in Intellij IDEA 13 by Gradle: Android Module and then selecting Mark this project as a library
