1.自定义权限:
<!-- 定义自定义权限 --> <permission android:name="com.example.f6k5i8.checkpermission.permission.SAY_HELLO" />
2.检查权限
下面这个hello中的sayHello()函数中检测权限,没有则异常.
public class Hello {
public static final String PERMISSION_SAY_HELLO = "com.example.f6k5i8.checkpermission.permission.SAY_HELLO";
public static void sayHello(Context context){
int ret = <span style="font-size:18px;color:#ff0000;"><strong>context.checkCallingOrSelfPermission(PERMISSION_SAY_HELLO)</strong></span>;
if (ret != PackageManager.PERMISSION_GRANTED){//GRANTED是访问 权限
throw new SecurityException("执行 sayHello 需要有com.example.f6k5i8.checkpermission.permission.SAY_HELLO 权限");
}
Log.i("CheckPermission","sayHello()... successed");
}
}
3.使用权限
在manifest.xml中
<uses-permission android:name="com.example.f6k5i8.checkpermission.permission.SAY_HELLO" />
在代码中:
Hello.sayHello(this);
