前面有一篇提到有關Android Property的文章

最近又碰到一些問題關於System Property的permission！

原來要在自己的application去對systemproperties做設定

我們不能亂取system property的屬性姓名

假設你要亂取，你必須在 system/core/init/property_service.c 做property permission的註冊

 1       #define  PERSISTENT_PROPERTY_DIR  "/data/property"
 2       struct  {
 3           const   char   * prefix;
 4          unsigned  int  uid;
 5      } property_perms[]  =  {
 6          {  " net.rmnet0. " ,    AID_RADIO },
 7          {  " net.gprs. " ,      AID_RADIO },
 8          {  " ril. " ,           AID_RADIO },
 9          {  " gsm. " ,           AID_RADIO },
10          {  " net.dns " ,        AID_RADIO },
11          {  " net.usb0 " ,       AID_RADIO },
12          {  " net. " ,           AID_SYSTEM },
13          {  " dev. " ,           AID_SYSTEM },
14          {  " runtime. " ,       AID_SYSTEM },
15          {  " hw. " ,            AID_SYSTEM },
16          {  " sys. " ,        AID_SYSTEM },
17          {  " service. " ,    AID_SYSTEM },
18          {  " wlan. " ,        AID_SYSTEM },
19          {  " dhcp. " ,        AID_SYSTEM },
20          {  " dhcp. " ,        AID_DHCP },
21          {  " debug. " ,        AID_SHELL },
22          {  " log. " ,        AID_SHELL },
23          {  " service.adb.root " ,    AID_SHELL },
24          {  " persist.sys. " ,    AID_SYSTEM },
25          {  " persist.service. " ,   AID_SYSTEM },
26          { NULL,  0  }
27      };

Android真的是太深奧的！一點一滴的累積！

要全部專精真的有點難，希望不要一直進版

東西變好多，oh~shit
