Android工具：Lint的使用

1.在cmd中執行：lint --show AllowBackup // 顯示lint中關於AllowBackup這個話題（issue）的解釋，執行結果如下：

AllowBackup
-----------
Summary: Ensure that allowBackup is explicitly set in the application's
manifest

Priority: 3 / 10
Severity: Warning
Category: Security

The allowBackup attribute determines if an application's data can be ba
and restored. It is documented at
http://developer.android.com/reference/android/R.attr.html#allowBackup

By default, this flag is set to true. When this flag is set to true,
application data can be backed up and restored by the user using adb ba
and adb restore.

This may have security consequences for an application. adb backup allo
users who have enabled USB debugging to copy application data off of th
device. Once backed up, all application data can be read by the user. a
restore allows creation of application data from a source specified by
user. Following a restore, applications should not assume that the data
permissions, and directory permissions were created by the application
itself.

Setting allowBackup="false" opts an application out of both backup and
restore.

To fix this warning, decide whether your application should support bac
and explicitly set android:allowBackup=(true|false)"

小結：本人在了解android:allowBackup屬性含義時，順帶發現了Lint的一些用法。以上為拋磚引玉，發現更多金礦就靠你自己啦！
