【问题描述】:
在我用eclipse创建Android App之前,它可以在标题栏左侧显示app图标,请看图片aa.png。
现在我用Android Studio创建Android App,我在manifest.xml文件中添加了代码android:icon="@mipmap/ic_launcher",但是app图标不显示,请看图片bb.png,为什么?
顺便说一句,如果我将compile 'com.android.support:appcompat-v7:22.1.1' 替换为compile 'com.android.support:appcompat-v7:18.0.0',图标会显示,为什么? com.android.support:appcompat-v7:22.1.1 有一些错误吗?
