android.permission.MODIFY_PHONE_STATE權限限制已經改爲系統權限
普通應用程序已經無法調用
所以網上找到的那些如何使用android.permission.MODIFY_PHONE_STATE的文章 均已失效
但仍有引用的辦法
就是讓你的程序程序系統程序
一種就是預製到ROM中
另一種就是使用系統簽名
第一種我已經試驗通過，第二種還有待驗證。
Also, just to save everyone some searching. I've been researching this and here's what happened:
David marked the permission MODIFY_PHONE_STATE as signatureOrSystem. That means only apps installed to the /system folder or signed with the certificate used to build the phone (i.e. your phone's manufacturer) will be able to use the permission.
As a developer, if you are using the permission there is NO WORK AROUND... unless you can convince every manufacturer to include your app as a preinstalled bloatware.
