更改啟動頁和閃屏頁對調導緻android app的名字發生變化解決辦法

write by tim@20230620

今天聚合發現一個問題，就是母包和管道包合并的時候，把母包啟動頁和聚合sdk閃屏頁對調之後，程式無BUG，正常運作，但是發現app裝上去app name變成了 splashActivity.

apktool 再次反編譯合并包，檢視清單

</manifest>           

application 裡面的android:label="新倚天屠龍記H5" label屬性正确的，但是為什麼就app名字變成了SplashActivity了呢？

就重點查smali代碼，最終找到原因：啟動頁的android:label優先級高于application 裡面的android:label

<activity android:exported="true" android:label="@string/title_activity_splash" android:name="com.stang.jhsdk.SplashActivity" android:theme="@style/Theme.三唐聚合sdk.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>           

是以，隻要更改啟動頁的android:label即可解決這個問題

在python打包腳本裡添加如下代碼即可解決問題

splash_activity_elem.attrib['{' + androidNS + '}exported'] = 'true'
    splash_activity_elem.attrib['{' + androidNS + '}label'] = fx['game_name']
