title: throws SecurityException when signing with the default debug keystore
body: <p>I am receiving a <strong>SecurityException</strong> since yesterday when I launch the service using signature protection level for permission with the default debug keystore. The strange thing is I wasn't receiving this error before yesterday and I didn't make any security related change.</p>
  
  <p>On the other hand, my own keystore using for releases is still working good. Related <strong>AndroidManifest.xml</strong> part:</p>
  
  <pre><code>&lt;permission android:name="com.my.app.privateservices"
      android:protectionLevel="signature" /&gt;
  
  &lt;service android:name=".MyService"
      android:permission="com.my.app.privateservices" /&gt;
  </code></pre>
