application requires feature(s) not available on your device

Question

I have an Android application on Android Market, but some users are complaining about an error shown when the installation starts, just after the download:

One of them sent me a video of this error showing up, and I could see that this error is not caused by the application, but probably in the verification of permission/features process.

As far as I know, this error is just happening on Motorola Droid/Milestone devices running Eclair, it doesn't happen with Froyo. Unfortunately, I don't have access to any device like this one in order to run logcat and check what's going on.

Here are my permission/features on AndroidManifest.xml:

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.location" />
<uses-feature android:name="android.hardware.telephony" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Answer 1

I finally found out what's happening by getting a Droid device and running logcat:

E/PackageManager( 1280): Package com.mycompany.myapp requires unavailable feature android.hardware.telephony; failing!

Motorola Droid devices running Eclair are not able to install applications that declare

<uses-feature android:name="android.hardware.telephony" />

in their manifest. It's very strange, though, because the Android Market should hide it from these devices. This is probably a bug caused by the changes made to the Eclair by Motorola, since it doesn't happen with other devices running Eclair, neither with the same Droid running Froyo.

Answer 2

According to the docs:

Android Market attempts to discover an application's implied feature requirements by examining other elements declared in the manifest file, specifically, <uses-permission> elements.

Given that, have you tried removing the uses-feature tags? Since those are implied by the uses-permissions tags, and you aren't using the "android:required" attribute.

Answer 3

The device say " this feature is not available in this device " when I'm installing an app downloaded from play store and i have to give it permission
