获取apk文件图标,版本,名称

Question

有没有办法可以获得尚未安装的软件包的应用程序名称,应用程序版本和应用程序图标？(对于sdcard上的一些apk文件)

Answer 1

我花了更多的时间,而不是承认寻找解决方案......并找到了它!:) :)

徘徊到这个参考:http: //code.google.com/p/android/issues/detail？id = 9151 我发现了从.apk文件获取图标和名称(标签,即)的技巧没有安装.

我希望用这个帮助别人还为时不晚:

 String APKFilePath = "mnt/sdcard/myapkfile.apk"; //For example...
 PackageManager pm = getPackageManager();
 PackageInfo    pi = pm.getPackageArchiveInfo(APKFilePath, 0);

 // the secret are these two lines....
 pi.applicationInfo.sourceDir       = APKFilePath;
 pi.applicationInfo.publicSourceDir = APKFilePath;
 //

 Drawable APKicon = pi.applicationInfo.loadIcon(pm);
 String   AppName = (String)pi.applicationInfo.loadLabel(pm);

经过轻度测试后,它似乎有效......哇.

Answer 2

我试过了:

PackageInfo info = getPackageManager().getPackageArchiveInfo(fullPath, 0);
ApplicationInfo appinfo = info.applicationInfo;
label = getPackageManager().getApplicationLabel(appinfo).toString();
img = getPackageManager().getApplicationIcon(info.packageName);

但如果没有安装apk,则无法使用此代码

Answer 3

我可以用得到的APK图标,版本,名称getPackageArchiveInfo(archiveFilePath, flags)和getApplicationIcon (ApplicationInfo info)

Answer 4

// Install a known apk file from the SD-Card
// or launch it if installed. 
// -hsigmond

protected void runAppFromApkFileOnSdCard() {

        final PackageManager pm = getActivity().getPackageManager();
        String apkFileName      = "application_name.apk";
        String fullPath         = "/sdcard/"+apkFileName;
        PackageInfo packageInfo = pm.getPackageArchiveInfo(fullPath, 0);
        Intent intent           = pm.getLaunchIntentForPackage(packageInfo.packageName);

        if( intent == null ){
            File file   = new File(fullPath);
            intent      = new Intent();
            intent.setAction(Intent.ACTION_VIEW);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.setDataAndType(Uri.fromFile(file),
            "application/vnd.android.package-archive");
        }
        startActivity(intent);
    }

使用:

packageInfo.applicationInfo.['name','icon','logo'] etc.

示例图标:

Drawable icon = packageInfo.applicationInfo.loadIcon(getActivity().getPackageManager());
