推荐答案

可以使用PackageManager方法getPackageArchiveInfo 从 APK 文件中检索信息.假设您的 APK 位于 SD 卡的根目录中，您可以使用以下代码:

You can use the PackageManager method getPackageArchiveInfo to retrieve the information from an APK file. Assuming your APK lives in the root of your SD card, you can use this code:

    String apkPath = Environment.getExternalStorageDirectory().getAbsolutePath() 
                   + "/MyApp.apk";
    PackageManager pm = getPackageManager();

    PackageInfo info = pm.getPackageArchiveInfo(apkPath, 
                           PackageManager.GET_ACTIVITIES);
    //Log.i("ActivityInfo", "Package name is " + info.packageName);

    for (android.content.pm.ActivityInfo a : info.activities) {
        Log.i("ActivityInfo", a.name);
    }

您可以在 ActivityInfo 和 PackageInfo 对象中找到大量其他信息.

There is plenty of additional information you can find in the ActivityInfo and PackageInfo objects.
