安卓手机不能安装软件其实有很多的原因，排除可以避免的原因（google授权），其他的硬件设施的支持，也可能出现软件不能安装的现象。有的是可以解决的，但有的是强制性原因，那就没有办法了。下面就来分析下软件不能安装的几个原因。
</p>
<p style="TEXT-INDENT: 2em">
<strong>1.最常见的就是，未知软体安装失败。</strong>
</p>
<p style="TEXT-INDENT: 2em">这个其实在塞班手机的时候就有这个权限，这个也只要在手机安全设置里面设置就可以了。这也是运营商为了保证用户不过乱的安装非官方应用程序而造成手机系统紊乱的现象而添加的一个选项。</p>
<p style="TEXT-INDENT: 2em">
解决办法：
<strong>设置安装权限即可（如图）</strong>
