的SQLite數據庫尚未創建

我試圖複製所有的手機通話記錄，以創建數據庫和代碼運行良好，但沒有.db文件在以下包genertated，的SQLite數據庫尚未創建

data/data/your.application.package/databases/

類代碼：

import java.text.SimpleDateFormat; 
import java.util.TimeZone; 
import java.util.Date; 
import java.text.DateFormat; 
import android.content.BroadcastReceiver; 
import android.content.ContentValues;

        Current_time=DateFormat.getDateTimeInstance().format(new Date()); 
        Log.i("ddd", ""+get_duration); 



        try

    } 

}

將對DBAdapter幫助器類爲logs.java

public class LocalDb {

public SQLiteDatabase mdb; 
static final String DATABASE_NAME ="DBImage";

private static final String Table1 = "create table if not exists " + Logs + "(id integer primary key autoincrement ," + "number text,type text,time text,duration text,date text)"; 

private static class DatabaseHelper extends SQLiteOpenHelper{ 

    public DatabaseHelper(Context context) { 
     super(context,DATABASE_NAME,null, DATABASE_VERSION); 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public void onCreate(SQLiteDatabase db) { 
     // TODO Auto-generated method stub 
     db.execSQL(Table1); 

    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // TODO Auto-generated method stub 
     db.execSQL("DROP TABLE IF EXISTS"+Table1); 

    } 


} 

public LocalDb(Context ctx){ 
    this.context=ctx;

public LocalDb open() throws SQLException{ 

    dbhelp=new DatabaseHelper(context); 
    mdb=dbhelp.getWritableDatabase(); 

    return this; 

} 
public void close(){ 
    dbhelp.close(); 
} 

public long insert_values(String Table,ContentValues initialvalues){ 


    return mdb.insert(Table, null, initialvalues); 

} 
public Cursor fetchMainLists(){ 

    String sql = "SELECT id,number,type,time,duration,date FROM Logs ";

你能確認你的'BroadcastReceiver'的'onReceive'方法實際上是否被調用嗎？ – patheticpat

您可以在'onReceive'方法中插入像'Log.d（TAG，「onReceive」）這樣的'Log'語句來查看它是否被實際調用。因爲數據庫在第一次被訪問之前不會被創建。 – patheticpat

d /標籤（15904）的onReceive – ekp

下面寫接收器代碼，而不是你的廣播接收器的代碼，它會解決你的問題。

你的代碼解決了我的數據庫的初始問題，但它沒有將值插入數據庫表 – ekp

@ekp你得到了什麼錯誤？ –

@ekp這不好，因爲你的問題現在已經解決了，如果你想知道更多的信息，那麼就發表另一個問題，或者告訴我這裏有完整的信息。 –

的SQLite數據庫尚未創建
