编辑：

我在清单文件中写了这段代码：

i have written this code in manifest file :

<uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />
    <!-- <uses-permission android:name="android.permission.INSTALL_PACKAGES"/> -->
    <application android:icon="@drawable/biz_logo"
        android:permission="android.permission.WRITE_CONTACTS">
        <activity android:name="com.biz.mlm.Main">
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:scheme="content" />
                <data android:scheme="file" />
                <data android:mimeType="application/vnd.android.package-archive" />
            </intent-filter>
        </activity>

推荐答案

不可能。正如其中一些链接指出的那样，自动安装APK并删除原始安装程序，而无需进一步的用户干预就被称为恶意软件。

Not possible. As some of those links point out, making an APK that automatically installs itself and deletes the original installer without any further user intervention is called malware.

您可以编写一个程序，如果用户授予相关权限，将会下载并安装任意的APK，但是我还没有看到一个很好的实现或文档。通常您可以使用以下代码调用默认系统安装程序：

You can write a program that will download and install arbitrary APKs if the user grants it the relevant permissions, but I'm yet to see a good implementation or documentation for this. Typically you can invoke the default system installer using code like this:

File apkFile = new File({path to APK});
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");
    startActivity(intent);
