几件事情...  雷诺回答......但也有多个错误：

few things ... Renaud answer ... but there are more errors:

// there is no such constructor ... Android looking for simple SampleContentProvider()
//public SampleContentProvider(Context context){
//  mContext=context;
//}

@Override
public boolean onCreate() {
    //so we move mContext initialization here
    mContext = getContext();
    dbHelper = new DatabaseHelper(mContext);
    return true;
}

接下来的：

public static final class ContentProviderHelper  {
    private ContentProviderHelper() {}
    //private static final String BASE_PATH = "yay"; we don't need it
    public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY); //you dont need it + "/" + BASE_PATH);
    public static final String CONTENT_ITEM_TYPE = ContentResolver.CURSOR_ITEM_BASE_TYPE + 
                                                        "/vnd." + COMPANY_NAME + "." + TABLE_NAME;//yay it's stupid :P BASE_PATH;
    public static final String CONTENT_TYPE =   ContentResolver.CURSOR_DIR_BASE_TYPE + 
                                                    "/vnd." + COMPANY_NAME + "." + TABLE_NAME;//yay it's stupid :P BASE_PATH;
    public static final String ID = "_id";
    public static final String TITLE = "title";
    public static final String TEXT = "text";
}

下一个test.java：

next in test.java:

    Uri uri = getContentResolver().insert(
            // we should replace SampleContentProvider.ContentProviderHelper.CONTENT_URI with CONTENT_URI + TABLE_NAME
            Uri.withAppendedPath(SampleContentProvider.ContentProviderHelper.CONTENT_URI, SampleContentProvider.TABLE_NAME), values);
