title: How can I add additional Android permissions for my UI test project only?
body: <p>I try to write files to the external SD card in a from <code>InstrumentationTestCase2</code> derived test case for pure testing purposes. This works all well when <code>android.permission.WRITE_EXTERNAL_STORAGE</code> is configured in the <code>AndroidManifest.xml</code> file of the application under test, but does not work if this setting is only present in the <code>AndroidManifest.xml</code> file of the test project.</p>
  
  <p>Naturally, I don't want to add this permission to the main manifest, since I only need this capability during my functional tests. How can I achieve that?</p>
