如何為NativeScript Android更新App-Icon

Question

我有一個已經部署到PlayStore的應用程序。 對於新的更新，我希望該應用程序顯示的圖標和開始屏幕與當前不同。

我的styles.xml ：

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- theme to use FOR launch screen-->
    <style name="LaunchScreenThemeBase" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="toolbarStyle">@style/NativeScriptToolbarStyle</item>

        <item name="colorPrimary">@color/ns_primary</item>
        <item name="colorPrimaryDark">@color/ns_primaryDark</item>
        <item name="colorAccent">@color/ns_accent</item>

        <item name="android:windowBackground">@drawable/splash_screen</item>
        <item name="android:windowNoTitle">true</item>

        <item name="android:windowActionBarOverlay">true</item>
        <item name="android:windowTranslucentStatus">true</item>

        <item name="android:windowFullscreen">true</item>
    </style>

    <style name="LaunchScreenTheme" parent="LaunchScreenThemeBase">
    </style>

    <!-- theme to use AFTER launch screen is loaded-->
    <style name="AppThemeBase" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="toolbarStyle">@style/NativeScriptToolbarStyle</item>

        <item name="colorPrimary">@color/ns_primary</item>
        <item name="colorPrimaryDark">@color/ns_primaryDark</item>
        <item name="colorAccent">@color/ns_accent</item>

        <item name="android:windowFullscreen">false</item>
    </style>

    <style name="AppTheme" parent="AppThemeBase">
    </style>

    <!-- theme for actioon-bar -->
    <style name="NativeScriptToolbarStyleBase" parent="Widget.AppCompat.Toolbar">
        <item name="android:background">@color/ns_primary</item>
        <item name="theme">@style/ThemeOverlay.AppCompat.ActionBar</item>
        <item name="popupTheme">@style/ThemeOverlay.AppCompat</item>

    </style>

    <style name="NativeScriptToolbarStyle" parent="NativeScriptToolbarStyleBase">
    </style>
</resources>

我的colors.xml ：

<resources>
    <color name="ns_primary">#F5F5F5</color>
    <color name="ns_primaryDark">#757575</color>
    <color name="ns_accent">#33B5E5</color>
    <color name="ns_blue">#272734</color>
</resources>

從我的AndroidManifest.xml ：

<application
        android:name="com.tns.NativeScriptApplication"
        android:allowBackup="true"
        android:icon="@drawable/icon"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
>

我有很多可繪制的文件夾，其中有些.png's位於（ icon.png和splashscreen.9.png ）中。 現在，如果我只是嘗試刪除這些文件並將新的.png文件放入其中，則在嘗試tns run android時會出現異常。

我已經嘗試刪除平台並讀取它（清理npm緩存），然后刪除.gradle 。 我還在根目錄中搜索.png ， icon和splashscreen ，但沒有找到其他圖片（均為最新圖片）。

我不確定我還應該嘗試什么，問Google到目前為止對我沒有幫助。

NativeScript 4.xx及更高版本引入了CLI命令，用於自動生成和替換應用程序圖標和啟動屏幕。

更改Android和iOS的應用程序圖標

tns resources generate icons  ../myIcon.png

更改Android和iOS的啟動屏幕

tns resources generate splashes ../myImage.png --background "#FF00FF"
