title: My apps will not install on device when downloaded from the Android Market
body: <p>I am unable to install my app onto a device even when it is downloaded from the Android Market. How can this be possible? If it were signed incorrectly wouldn't the market not accept it? I have tried to install it by isolating various activities but none seem to work even when I reduce it to a simple hello world application. The app has a tab view, two being webviews [one includes a reload button] and one tab that allows a user to send an email to a submission page. Does anyone have any ideas as to what I am missing?</p>
  
  <p>Thank you all very much in advance. </p>
  
  <p>EDIT:</p>
  
  <p>It's being downloaded on the LG Ally running 2.2.2 and my app runs fine on an 2.2 emulator. It is compiled with a min level of 4. Here is my AndroidManifest file </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  </code></pre>

      </p>
  
  <pre><code>&lt;application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="false"&gt;
      &lt;activity android:name=".BrotipsTabs"
                android:label="Brotips"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;

  <p>By not working I mean it refuses to install and claims it never did while an icon remains on the phone.</p>
