Answer 1

使數據庫的src/main /資產的文件夾dbname.db

，並使用此代碼

private static String DB_NAME = "dbname.db"; 
private static String DB_PATH = ""; 
DB_PATH = "/data/data/" + context.getPackageName() + "/databases/"; 


private void copyDataBase() throws IOException{ 
     AssetManager assets = mContext.getAssets(); 
     InputStream mInput = assets.open("hashvetar.db"); 
     String outFileName = DB_PATH + DB_NAME; 
     OutputStream mOutput = new FileOutputStream(outFileName); 
     byte[] mBuffer = new byte[1024]; 
     int mLength; 
     while ((mLength = mInput.read(mBuffer))>0) 
     { 
      mOutput.write(mBuffer, 0, mLength); 
     } 
     mOutput.flush(); 
     mOutput.close(); 
     mInput.close(); 
}
