程式判斷手機ROOT狀态,擷取ROOT權限

判斷手機是否具有ROOT權限

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

public boolean isRoot() {  boolean root = false ;  try {  if ((! new File( "/system/bin/su" ).exists())  && (! new File( "/system/xbin/su" ).exists())) {  root = false ;  } else {  root = true ;  }  } catch (Exception e) {  }  return root;  }

上面傳回的參數就知道手機是否具有ROOT權限了。

向ROOT權限發送請求資訊,以擷取ROOT權限

此方法不涉及底層, 這種方式需要使用者點選确認才可以擷取.
