    <p><em>Issue is here</em></p>
  </blockquote>
  
  <p>If i install <strong>Application 2</strong> first and then install <strong>application 1</strong>.</p>
  
  <p><strong>then i got read permission error.</strong></p>
  
  <p><strong>One solution.</strong>
  Add below code in manifest <code>protection_level = "signature"</code> then working fine.
  But both application is different with different sign.</p>
  
  <p>If anyone know how to solve this issue, Please write the answer ! Response is appreciated </p>
