parse error trying to install apps on my phone

Question

I'm having issues trying to put my own apps on my phone. I've looked around and no one has been able to help me so far. A bit of background information, I'm using the latest version of eclipse IDE, trying to get apps onto my galaxy s. I tried installing apps through gmail. When I go to install the app I get a parse error and it doesn't install. I have also tried using this method to install my app onto a htc wildfire s however I get the same issue. Is there a quick fix for this? Thanks for your time; any insight into what the problem is will be great.

Things I've tried: Ok I still have a parse error when I try installing my app. The min sdkversion was set to 9 which seems right to me as that is the api level for gingerbread which galaxy s uses (i think). I haven't set a target sdkversion yet as according to the android developer guide it if not stated it defaults to the minsdkversion. I also tried setting the minsdkversion to 1 and still no luck. Any ideas?

<uses-sdk android:minSdkVersion="7" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" 
    android:debuggable="true">
    <activity
        android:name=".GuitarTunerActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

Solution

Parse error usually occurs if your app supports a higher version of Android than the version of OS on your phone. Egs: your phone has 2.1 and application supports 2.2 onwards
