是否可以在运行时以编程方式更新 Android Manifest？

Question

我想达到的目标：

I am creating an application which changes the app icon and app name programmatically.

我取得的成绩：

I've already achieved this because there are only 5 names and icons by declaring activity-alias in android manifest.

我面临的问题：

If you have only 5 names then it's easy to declare it in manifest. But what if you don't know the no. of names and you have to update the manifest programmatically.

下面是我的代码：

AndroidManifest.xml

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

    <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
    <uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity-alias android:label="@string/app_name1"
            android:icon="@drawable/ic_launcher"
            android:name=".MainActivity-Red"
            android:enabled="false"
            android:targetActivity=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity-alias>

        <activity-alias android:label="@string/app_name2"
            android:icon="@drawable/ic_launcher_1"
            android:name=".MainActivity-Pink"
            android:enabled="false"
            android:targetActivity=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity-alias>

        <activity-alias android:label="@string/app_name3"
            android:icon="@drawable/ic_launcher_2"
            android:name=".MainActivity-Blue"
            android:enabled="false"
            android:targetActivity=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity-alias>

        <activity-alias android:label="@string/app_name4"
            android:icon="@drawable/ic_launcher_3"
            android:name=".MainActivity-Grey"
            android:enabled="false"
            android:targetActivity=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity-alias>
    </application>
</manifest>

在MainActivity.java

    img.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if (view.getTag().equals(0)) {
                changeIcon("com.drawerstack.MainActivity-Red");
                removeIcon("com.drawerstack.MainActivity");
                removeIcon("com.drawerstack.MainActivity-Pink");
                removeIcon("com.drawerstack.MainActivity-Blue");
                removeIcon("com.drawerstack.MainActivity-Grey");
            } else if (view.getTag().equals(1)) {
                changeIcon("com.drawerstack.MainActivity-Pink");
                removeIcon("com.drawerstack.MainActivity-Blue");
                removeIcon("com.drawerstack.MainActivity-Grey");
                removeIcon("com.drawerstack.MainActivity-Red");
                removeIcon("com.drawerstack.MainActivity");
            } else if (view.getTag().equals(2)) {

                removeIcon("com.drawerstack.MainActivity-Pink");
                removeIcon("com.drawerstack.MainActivity-Grey");
                removeIcon("com.drawerstack.MainActivity-Red");
                removeIcon("com.drawerstack.MainActivity");

                changeIcon("com.drawerstack.MainActivity-Grey");
                removeIcon("com.drawerstack.MainActivity-Pink");
                removeIcon("com.drawerstack.MainActivity-Red");
                removeIcon("com.drawerstack.MainActivity-Blue");
                removeIcon("com.drawerstack.MainActivity");
            }
        }
    });


private void changeIcon(final String pkgName) {

    doAsynchronousTask = new TimerTask() {

    timer.schedule(doAsynchronousTask, 0, 50000);

假设您的问题是标题中的问题：

Is it possible to update Android Manifest programmatically?

答案是否，不可能以编程方式做到这一点。

您可以 enable/disable 在您的清单中声明的组件，但您不能从那里添加或删除某些内容，因为正如其名称所示，它是一个清单文件，系统 "reads" 当它会安装您的应用程序。因此，您在该清单中声明了应用程序的界面，以后您无法更改它，除非您使用另一个清单重新安装该应用程序。

假设系统为您提供了这样做的能力。然后你会动态地向你的清单添加一些权限，而用户在从 Play 商店下载你的应用程序时还没有批准。
