我修改了package属性值，能编译安装却打不开，求大神指点```javascript
复制代码<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.abc123.app"
android:versionCode="101"
android:versionName="1.0.1" >
<supports-screens
android:anyDensity="true"
android:largeScreens="true"
android:normalScreens="true"
android:resizeable="true"
android:smallScreens="true" />
