Question

There is an application which can not be runed on particular devices. I have this in Manifest.xml:

<uses-sdk android:minSdkVersion="8" />

And it works on HTC sensation with Android 4.0, but for some reason it is not compatible with Samsung Galaxy Tablet 2 7.0. (Android 4)

When I upload it in Android market, also I can see that the Tablet is not supported.

I can not understand the reason, can you please let me know why?

Manifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    android:installLocation="auto"
    package="test.newversion"
    android:versionCode="1"
    android:versionName="2.0" >

    <uses-sdk android:minSdkVersion="8" />

    <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
    <uses-permission android:name="android.permission.USE_CREDENTIALS" />
    <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:icon="@drawable/app_logo"
        android:label="@string/app_name" >
        <uses-library android:name="com.google.android.maps" />

    </application>

</manifest>

Some permissions implicitly add requirements on the hardware. For example the docu for CAMERA says:

This will automatically enforce the manifest element for all camera features. If you do not require all camera features or can properly operate if a camera is not available, then you must modify your manifest as appropriate in order to install on devices that don’t support all camera features.

If you don’t need all, add explicit uses-feature elements with android:required="false"
