"your device isn't compatible with this version"

Issue

I put an app in the play store and my friend, who is running 4.0.3 on two devices, got the following message when trying to install my app : "your device isn't compatible with this version".

One device allows it to install and the other doesn't. I allow for API 3-15 and both devices are 4.0.3. What's the problem?

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.snotyak.basicfuelcalcpro"

    <uses-sdk
        android:minSdkVersion="4" />

        <activity android:name=".AboutActivity"></activity>
        <activity android:name=".HistoryActivity" />
        <activity android:name=".AnalysisActivity" />
    </application>
</manifest>

Solution

Double check the <uses-feature> tag in your AndroidManifest.xml file. It sounds like your application requires a feature that one of the devices doesn't support.

You should also check to see if you have the following declared in your AndroidManifest.xml,

<uses-sdk
    android:minSdkVersion="3" />

You want your application to work for devices running API 3 and above (not APIs 3 through 15). The code above will ensure that your application works with all devices above API 3. Note that you generally don't want to use the android:maxSdkVersion attribute (if you are currently using it).
