Android 获取未安装的app图标

public static Drawable getApkIcon(String Path)
    {
       String apkPath = Path; // apk 文件所在的路径
        Drawable icon = null;
        PackageManager pm = context.getPackageManager();
        PackageInfo info = pm.getPackageArchiveInfo(apkPath ,PackageManager.GET_ACTIVITIES);
            if (info != null) {
                 ApplicationInfo appInfo = info.applicationInfo;
                 appInfo.publicSourceDir = apkPath;//add-absolute path of app Drawable icon = pm.getApplicationIcon(appInfo);
                 icon = pm.getApplicationIcon(appInfo);
            }
        return icon;

    }

网上也有这种方法但是获取失败了，无意间看到大神评论这是因为对于未安装应用ApplicationInfo未能获取到对应的source path。 只要在getApplicationIcon()前传入source path即可： appInfo.publicSourceDir = mFilePath;//add-absolute path of app Drawable icon = pm.getApplicationIcon(appInfo);
