5、配置微信activity

<activityandroid:name=".wxapi.WXEntryActivity"android:configChanges="keyboardHidden|orientation|screenSize"android:exported="true"android:screenOrientation="portrait"android:theme="@android:style/Theme.Translucent.NoTitleBar" /><activityandroid:name=".wxapi.WXPayEntryActivity"android:exported="true"android:launchMode="singleTop" />
