title: android: device not supported by app- why?
body: <p>I am currently developing a camera app. Now one of the users is complaining that his device is not supported. It's a <a href="http://www.specsbox.com/819/acer-iconia-a200-tablet.html" rel="noreferrer">Acer A200</a>:</p>
  
  <p>I don't see any reason why android market / google play marks the app as <strong>not supported</strong> for this device. 
  Do you know what might be the reason?</p>
  
  <p>Here is the manifest:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="net.ttttrash.myapp"
      android:versionCode="32"
      android:versionName="3.2" &gt;
  
      &lt;application
          android:icon="@drawable/icon"
          android:label="@string/app_name"
          android:hardwareAccelerated="true"&gt;
          &lt;activity
              android:name=".CameraActivity"
              android:configChanges="keyboard|orientation|keyboardHidden"
              android:label="@string/app_name"
              android:windowSoftInputMode="adjustPan" &gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="android.intent.action.MAIN" /&gt;
  
                  &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
              &lt;/intent-filter&gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="android.media.action.IMAGE_CAPTURE" /&gt;
  
                  &lt;category android:name="android.intent.category.DEFAULT" /&gt;
              &lt;/intent-filter&gt;
          &lt;/activity&gt;
          &lt;activity
              android:name="net.ttttrash.myapp.PreferenceActivity"
              android:label="@string/set_preferences" &gt;
          &lt;/activity&gt;
          &lt;activity

              android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"&gt;
          &lt;/activity&gt;
  
      &lt;/application&gt;
  
      &lt;uses-sdk
          android:minSdkVersion="7"
          android:targetSdkVersion="8" /&gt;

  &lt;/manifest&gt;
