android - Dex Loader 无法执行多个 dex 文件定义

Question

好的，现在我真的被困在这里了。我不知道该做什么，去哪里或任何事情!

我一直在尝试卸载、重新安装 SDK 和 Eclipse 版本，尝试用谷歌搜索出来，但是 nu-uh... 什么都没有!!!

我可以在模拟器中运行我的应用程序，但我无法导出它...

[2011-10-07 16:35:30 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/dreamhawk/kalori/DataBaseHelper;

这是dataBaseHelper

package com.dreamhawk.kalori;

           Log.w("Kalori", "Upgrading database from version " + oldVersion + " to "
               + newVersion + ", which will destroy all old data");
           db.execSQL("DROP TABLE IF EXISTS Livsmedel");
           onCreate(db);

       }

    public DataBaseHelper open() throws SQLException {

        int length;
        while ((length = assetsDB.read(buffer)) > 0) {
            dbOut.write(buffer, 0, length);
        }

        dbOut.flush();
        dbOut.close();

    }

    public Cursor fetchAllNotes() {

        return myDb.query(DATABASE_TABLE, new String[] { KEY_ROWID, KEY_TITLE,
                KEY_BODY }, null, null, null, null, null);
    }

    public void openDataBase() throws SQLException {
        String dbPath = DB_PATH + DB_NAME;
        myDb = SQLiteDatabase.openDatabase(dbPath, null,
                SQLiteDatabase.OPEN_READWRITE);
    }

}

我怀疑:

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

但我不知道该怎么办......请帮助! :'(

Answer 1

bin/dexedLibs 中有一个文件libs中存在相同的文件

在库中删除它，它应该可以工作。

对我来说是 android-support-v4.jar。

希望对你有帮助
