是否有可能在没有root的情况下在Android设备上合并/安装拆分APK文件(AKA“app bundle”)?

问题描述 投票:7回答:4

背景

在过去,我曾询问有关app-bundle / split apk文件的共享或备份,here

这似乎是一项几乎不可能的任务,我只能弄清楚如何安装拆分APK文件,即便如此,它只能通过adb:

adb install-multiple apk1 apk2 ...

问题

我被告知实际上应该可以将多个拆分APK文件合并到一个我可以安装的文件(here),但是没有给出如何做到这一点。

这对于以后保存(备份)非常有用,因为目前无法在设备中安装split-apk文件。

事实上,这是一个非常重要的问题,我不知道任何可以处理拆分APK文件(应用程序包)的备份应用程序,这包括Titanium应用程序。

我发现了什么

我拿了一个使用app-bundle的示例应用程序,名为“AirBnb”。

查看它拥有的文件,这些是Play商店决定下载的内容:

enter image description here

所以我试着进入每一个。 “基地”是主要的,所以我跳过它看其他人。对我来说似乎所有这些文件都在:

  • “META-INF”
  • “resources.arsc”
  • “AndroidManifest.xml中”
  • 在具有“xxxhdpi”的情况下,我也得到“res”文件夹。

事情是,因为那些都存在于多个地方,我不知道如何合并它们。

问题

  1. 将这些全部合并到一个APK文件中的方法是什么?
  2. 是否可以安装没有root和没有PC的拆分APK文件?这在过去的备份应用程序(如Titanium)上是可行的,但仅限于普通的APK文件,而不是应用程序包(拆分apk)。

编辑:我已经设定了赏金。如果您知道解决方案,请显示它。展示你已经测试过的东西。合并分割APK文件或安装它们,无需root和right在设备上。


编辑:可悲的是,这里的所有解决方案都没有工作,有或没有root,即使我找到了一个成功的应用程序(有和没有root),称为“SAI(拆分APK安装程序)”(我认为它存储库是here,在我投入赏金之后找到的)。

我正在投入新的奖金。请发布新答案的人表示无论是否使用root都可以。如果需要,在Github上显示(这里只是重要的东西)。我知道这个应用程序是开源的,但是对我来说这很重要,并且与其他人共享,因为目前显示的内容不起作用,并且需要root,即使它并不是真的需要。

这次我不会给予赏金,直到我看到确实有效的东西(之前我的时间很短,并且给予我认为应该有效的答案)。

没有root必需的实现检查这个github链接:qazxsw poi

我们必须创建一个服务并在session.commit()中传递该句柄

编辑:由于解决方案有效,但在这里没有真正发布,我决定在将其标记为正确的解决方案之前编写它。这是代码:

表现

 Intent callbackIntent = new Intent(getApplicationContext(), APKInstallService.class);
 PendingIntent pendingIntent = PendingIntent.getService(getApplicationContext(), 0, callbackIntent, 0);
 session.commit(pendingIntent.getIntentSender());

它将此代码称为adb install-multiple apk1 apk2 ...

install-multiple

反过来调用Pm.java或执行PackageManagerService代码的新方法,两者都是相似的

我试图在我的应用程序中集成该代码,我遇到的问题,apk安装无法完成,这是由于应用程序需要的原因。

 std::string install_cmd;
    if (_use_legacy_install()) {
        install_cmd = "exec:pm";
    } else {
        install_cmd = "exec:cmd package";
    }

    std::string cmd = android::base::StringPrintf("%s install-create -S %" PRIu64, install_cmd.c_str(), total_size);
    for (i = 1; i < first_apk; i++) {
        cmd += " " + escape_arg(argv[i]);
    }

但它仅适用于system-priv应用程序。当我从adb shell执行这些步骤时,apk安装成功,当我创建我的应用程序时,系统priv-app apk安装成功。

用于调用PackageManager的新api的代码,大多数是从Pm.java复制的。安装split apks的步骤

  1. 使用参数-S创建会话,返回会话ID。 (install-create,-S,52488426)52488426 - apks的总大小。
  2. 使用大小,名称和路径在该会话中编写拆分apks (install-write,-S,44334187,824704264,1_base.apk, - ) (install-write,-S,1262034,824704264,2_split_config.en.apk, - ) (install-write,-S,266117,824704264,3_split_config.hdpi.apk, - ) (install-write,-S,6626088,824704264,4_split_config.x86.apk, - )
  3. 使用会话ID提交会话 (install-commit,824704264)

我已将airbnb apk放入我的SD卡中。

<uses-permission android:name="android.permission.INSTALL_PACKAGES"/>

并调用函数来安装apk。

OnePlus5:/sdcard/com.airbnb.android-1 $ ll

这是我们执行adb install-multiple时在Pm.java中实际接收的命令列表

        Log.d(TAG, "doCommitSession: " + packageInstaller.getMySessions());

private InstallParams makeInstallParams(long totalSize ) {
    final PackageInstaller.SessionParams sessionParams = new PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL);
    final InstallParams params = new InstallParams();
    params.sessionParams = sessionParams;
    String opt;
    sessionParams.setSize(totalSize);
    return params;
}

所以对于不是系统priv-app的应用程序,我不知道他们怎么能安装split apks。作为系统priv-app的Play商店可以使用这些api并安装拆分apks而不会出现任何问题。

在Android App Bundle中,您可以使用带有04-01 16:04:40.626 4886 4886 D Pm : run() called with: args = [[install-create, -S, 52488426]] 04-01 16:04:41.862 4897 4897 D Pm : run() called with: args = [[install-write, -S, 44334187, 824704264, 1_base.apk, -]] 04-01 16:04:56.036 4912 4912 D Pm : run() called with: args = [[install-write, -S, 1262034, 824704264, 2_split_config.en.apk, -]] 04-01 16:04:57.584 4924 4924 D Pm : run() called with: args = [[install-write, -S, 266117, 824704264, 3_split_config.hdpi.apk, -]] 04-01 16:04:58.842 4936 4936 D Pm : run() called with: args = [[install-write, -S, 6626088, 824704264, 4_split_config.x86.apk, -]] 04-01 16:05:01.304 4948 4948 D Pm : run() called with: args = [[install-commit, 824704264]] 标志的bundletool build-apks命令生成“通用APK”。这将生成一个与所有设备(您的应用支持)兼容的单个“胖”APK。

我知道这并不是严格回答你的问题,但尝试合并APK不仅是一项复杂的任务,而且会导致很多案件出现错误。

如果您有root,则可以使用此代码。

在执行此代码之前,请获取读/写SD卡权限(通过运行时权限或设置应用程序授予的权限)。 airbnb apk在运行此代码后成功安装。

使用args“/ split-apks /”调用此函数,我已将airbnb split apks放在/ sdcard / split-apks /中的目录中。

--mode=universal

编辑:相同的代码,但在Kotlin,因为它更短:

样品用量:

installApk("/split-apks/");


 public void installApk(String apkFolderPath)

    PackageInstaller packageInstaller =  getPackageManager().getPackageInstaller();
    HashMap<String, Long> nameSizeMap = new HashMap<>();

    File folder = new File(Environment.getExternalStorageDirectory().getPath()+ apkFolderPath);
    File[] listOfFiles = folder.listFiles();

        if (listOfFiles[i].isFile()) {
            System.out.println("File " + listOfFiles[i].getName());
            nameSizeMap.put(listOfFiles[i].getName(),listOfFiles[i].length());
            totalSize += listOfFiles[i].length();
        }
    }

    String su = "/system/xbin/su";


    final String[] pm_install_create = new String[]{su, "-c", "pm" ,"install-create", "-S", Long.toString(totalSize) };
    execute(null, pm_install_create);

    List<PackageInstaller.SessionInfo> sessions = packageInstaller.getAllSessions();

    int sessId = sessions.get(0).getSessionId();

    String sessionId = Integer.toString(sessId);


    for(Map.Entry<String,Long> entry : nameSizeMap.entrySet())
    {
        String[] pm_install_write = new String[]{su, "-c", "pm" ,"install-write", "-S", Long.toString(entry.getValue()),sessionId, entry.getKey(), Environment.getExternalStorageDirectory().getPath()+apkFolderPath+ entry.getKey()};

        execute(null,pm_install_write);

    }

    String[] pm_install_commit  = new String[]{su, "-c", "pm" ,"install-commit", sessionId};


    execute(null, pm_install_commit);

}
public String execute(Map<String, String> environvenmentVars, String[] cmd) {

    boolean DEBUG = true;
    if (DEBUG)
        Log.d("log","command is " + Arrays.toString(cmd));

        Process process = Runtime.getRuntime().exec(cmd);
        if (DEBUG)
