title: How to Install the app twice without interference in android?
body: <p>I have an Android app (let's called X), I want to create a second app X2 but based on the other app. So I changed the manifest application name property to X2 also I changed the package name...but still when I install X2, app X is erased!</p>
  
  <p>What properties should I change so I can install the two app independently on one devices. I'm working on eclispe.</p>
  
  <pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.company.app1"

      &lt;application
          android:allowBackup="true"
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name1"
          android:theme="@style/AppTheme" &gt;
