将Android源代码导入ADT（Eclipse）时报告的错误

Question

I downloaded source code and built Android (version 4.3) without errors (it works fine if I run it in emulator). Now I'm following this tutorial https://source.android.com/source/using-eclipse.html to import Android Project into eclipse workspace. After creating project from existing code, when workspace rebuild, eclipse throws 5131 errors and 12029 warnings.

As far as I see, all errors are of same origin "Something cannot be resolved..."

For example in packages/apps/Calendar/src in package com.android.calendar there is EventInfoFragment class with following imports:

import static android.provider.CalendarContract.EXTRA_EVENT_ALL_DAY;
import static android.provider.CalendarContract.EXTRA_EVENT_BEGIN_TIME;
import static android.provider.CalendarContract.EXTRA_EVENT_END_TIME;
import static com.android.calendar.CalendarController.EVENT_EDIT_ON_LAUNCH;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;

These imports cannot be resolved:

import com.android.colorpicker.ColorPickerSwatch.OnColorSelectedListener;
import com.android.colorpicker.HsvColorComparator;

My eclipse is from ADT.

I think that project is missing some libs/jars but I'm stuck here. If anyone have an idea, I will be most thankfull.

Answer 1

There are no such imports: com.android.colorpicker.* in the official SDK.
A little search brought me up with this library: Android Colorpicker that uses the packagename com.android.colorpicker . So try importing this library and add it to your imported project.

Answer 2

Delete bin folder in your project then clean your project.
if your problem is not solved, probably problem is SDK files.
also you can try this way:
1 - create a new project
2 - delete fragment_main in res/layout 3 - delete all generated code in main_activity class except:

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

Note: MainActivity must extend Activity instead of ActionBarActivity
