設定android檔案許可權

String dbfile = "/mnt/sdcard/eMenu/cookbook.db";

File file = new File(dbfile);

LogD("filename: "+file.toString());//測試一下檔案是否有效

try {

String command = "chmod 777 " + dbfile;//全部許可權

LogD("command = " + command);

Runtime runtime = Runtime.getRuntime();

Process proc = runtime.exec(command);

}

catch (IOException e)

{

LogD("chmod fail!!!!:" +e.getMessage());

}

 

android程式訪問sd卡上的資料庫，需要給程式加上，android.permission.WRITE_EXTERNAL_STORAGE許可權
