複製資源文件到SD卡

private void copyBigDataToSD(String strOutFileName) throws IOException 
    {  
        InputStream myInput;  
        OutputStream myOutput = new FileOutputStream(strOutFileName);  
        myInput = this.getAssets().open("videoChar.apk");  
        byte[] buffer = new byte[1024];  
        int length = myInput.read(buffer);
        while(length > 0)
        {
            myOutput.write(buffer, 0, length); 
            length = myInput.read(buffer);
        }
        
        myOutput.flush();  
        myInput.close();  
        myOutput.close();  
        System.out.println("拷貝成功");
    }

這段代碼就是把assets目錄下的文件拷貝到SDK java

填入的參數就是你輸出的路徑 ide

相似Environment.getExternalStorageDirectory()+"/videoChar.apk" this
