结合上述三篇文章，选择已下折中方案：

思路：

1.使用adb指令获取包名

private void runCommand() {
    try {
        Process process = Runtime.getRuntime().exec("adb shell pm list package -3");
        BufferedReader bis = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = null;
        while ((line = bis.readLine()) != null) {
            System.out.println("runCommand, line=" + line);
        }
    } catch (IOException e) {
        System.out.println("runCommand,e=" + e);
    }
}

2.根据包名使用PackageManager获取app的实际名字

private void getAppList() {
    PackageManager pm = getPackageManager();
    // Return a List of all packages that are installed on the device.
    List<PackageInfo> packages = pm.getInstalledPackages(0);
    for (PackageInfo packageInfo : packages) {
        // 判断系统/非系统应用
        if ((packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0) // 非系统应用
        {
            System.out.println("getAppList, packageInfo=" + packageInfo.packageName);
        } else {
            // 系统应用        
        }
    }
}

3.结合使用

private void runCommand() {
    try {
        PackageManager pm = getPackageManager();
        Process process = Runtime.getRuntime().exec("adb shell pm list package -3");
        BufferedReader bis = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = null;
        while ((line = bis.readLine()) != null) {
            PackageInfo packageInfo = App.instance.getPackageManager().getPackageInfo(line.replace("package:", ""), PackageManager.GET_GIDS);
            System.out.println("runCommand, line=" + line+"packageInfo.packageName" + ":" + packageInfo.applicationInfo.loadLabel(pm).toString());
        }
    } catch (IOException e) {
        System.out.println("runCommand,e=" + e);
    }
}
