解决方法
<activity android:name="BrowserActivity"
android:label="@string/application_name"
android:launchMode="singleTask"
android:alwaysRetainTaskState="true"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|touchscreen"
android:theme="@style/BrowserTheme"
android:windowSoftInputMode="adjustResize" >
android:configChanges="mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|fontScale"
二.在解决客户自启APK,会运行两次OnCreate生命周期
分析结果:是由于使用了4G通讯模块,加载模块的使用会导致 Activity关闭并重启自身
在main Activity中添加 android:configChanges = "mnc|mcc"即可
