Question

I have made a Android app and when I finished it and tested it through eclipse and Android SDK it works fine.. But when I test it on my android phone and install it with an app called AppInstaller and run it then it says “app not installed on device”.. WTF? How is that possible when its in the menu and I can tap on it?

This is my code. (And yes I did X out the website on purpose)

MANIFEST.XML:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="XXXXXXX"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="10" />
<uses-permission android:name="android.permission.INTERNET" />

<application
    android:icon="@drawable/new_launcher"
    android:label="@string/app_name"
    android:permission="android.permission.INTERNET"
    android:description="@string/app_description">

    <activity
        android:name="XXXXX"
        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>

“app not installed on device” is a message I’ve gotten when the SD card is mounted (and unavailable), or when trying to tap a shortcut on the desktop to an app that’s been removed in some way. If this is the problem I’d guess your case would be the former.
