Question

我尝试访问另一个应用程序的数据库，我想从我的应用程序中插入该数据库的数据。我在我的手机上测试它（root）但我得到错误。谁能帮我？

12-30 00:01:27.315: E/SQLiteLog(10477): (14) os_unix.c:30241: (13) open(/data/data/com.otherapplication/databases/records.db) - 
12-30 00:01:27.376: E/SQLiteDatabase(10477): Failed to open database '/data/data/com.otherapplication/databases/records.db'.
12-30 00:01:27.376: E/SQLiteDatabase(10477):    at com.test.MySQLiteOpenHelper.insertData(MySQLiteOpenHelper.java:28)
12-30 00:01:27.376: E/SQLiteDatabase(10477):    at com.test.MainActivity.test(MainActivity.java:45)
12-30 00:01:27.446: E/AndroidRuntime(10477):    at com.test.MySQLiteOpenHelper.insertData(MySQLiteOpenHelper.java:28)
12-30 00:01:27.446: E/AndroidRuntime(10477):    at com.test.MainActivity.test(MainActivity.java:45)

以下是文件， MySQLiteOpenHelper.java：

package com.test;

import java.util.HashMap;

import android.content.ContentValues;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class MySQLiteOpenHelper extends SQLiteOpenHelper {
    MySQLiteOpenHelper(Context context) {
        super(context, "/data/data/com.otherapplication/databases/records.db", null, 1);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // TODO Auto-generated method stub

    }

    public void insertData() { 
        SQLiteDatabase database = this.getWritableDatabase(); 
        ContentValues values = new ContentValues(); 
        values.put("id", "testvalue");
        database.insert("table", null, values);
        database.close(); 
        }


}

MainActivity.java

public class MainActivity extends Activity {
    MySQLiteOpenHelper controller = new MySQLiteOpenHelper(this);
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void test(View v) {
        controller.insertData();
    }
}

我找到了解决方案：

我对该应用程序的'databases'文件夹和该数据库文件执行了chmod 777。现在我可以从我的应用程序中插入数据。

其他应用程序的Android Access SQLite数据库
