设置android文件权限

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

File file = new File(dbfile);

LogD("filename: "+file.toString());//测试一下文件是否有效

try {

String command = "chmod 777 " + dbfile;//全部权限

LogD("command = " + command);

Runtime runtime = Runtime.getRuntime();

Process proc = runtime.exec(command);

}

catch (IOException e)

{

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

}

 

android程序访问sd卡上的数据库，需要给程序加上，android.permission.WRITE_EXTERNAL_STORAGE权限
