android 代码实现通过apk安装包获得apk包名

public static String getApkPackageName(Context context, String apkPath) {
        PackageManager pm = context.getPackageManager();
        PackageInfo info = pm.getPackageArchiveInfo(apkPath, PackageManager.GET_ACTIVITIES);
        ApplicationInfo appInfo = null;
        String packageName = "";
        if (info != null) {
            appInfo = info.applicationInfo;
            packageName = appInfo.packageName;  //得到apk包名
        }
        return packageName;
    }
