Answer 1

Try this:

      <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.xxx.xxxx">

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.Manifest.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.GET_TASKS" />

    <supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:smallScreens="true"
        android:xlargeScreens="true" />

    <application
------------------------
-------------------
/>

Add this in Manifest below permission and above <application/> Tag

Answer 2

According to the list of status codes at Wikipedia this means that:

504 Gateway Timeout
The server was acting as a gateway or proxy and did not receive a timely response from the upstream server.
In other words: the culprit should neither be (on) your device, nor (at) Google Play -- but in between.

In order to fix it you have some methods:

Method 1:

• Clear data
• Clear cache of google play store & google service framework

Method 2:

• Remove your google account
• Reboot
• Re-add account

If it doesn't work it cloud be related to the device lack of space for example.
