获取第 3 方应用的清单文件 [英] Get manifest file for a 3rd party app

问题描述

这个应用程序允许您浏览应用程序的清单文件.它是如何做到的?我在操作系统的 API 中找不到任何用于获取另一个应用程序清单文件的内容.

This application allows you to browse applications' manifest files. How does it do that? I can't find anything in the OS's API for getting another application's manifest file.

推荐答案

首先，您可以像这样获取应用程序列表:

First, you can get a list of Applications like so:

PackageManager pm = getActivity().getPackageManager();
List<ApplicationInfo> apps = pm.getInstalledApplications(
        PackageManager.GET_META_DATA | PackageManager.GET_SHARED_LIBRARY_FILES
    );

然后可以从以下位置获取APK的位置:

Then the location of the APK can be gotten from:

apps.get(x).publicSourceDir

上面将有一个值，例如:

The above will have a value such as:

/data/app/com.example.someonesapp.apk

从那里可以像这样从 .apk 访问清单文件:

From there the manifest file can be accessed from the .apk like so:

try {
    ZipFile apk = new ZipFile("/data/app/com.example.someonesapp.apk");
    ZipEntry manifest = apk.getEntry("AndroidManifest.xml");
    if (manifest != null){
        Log.d("ManifestGetter", "Manifest size = " + manifest.getSize());
        InputStream stream = apk.getInputStream(manifest);
        // do stuff with the file here e.g. get contents
        stream.close();
    }
    apk.close();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} 

最重要的是，不需要 root

Best of all, root is not required
