设备上未安装Android App

Question

I am working on a sample android app to learn more about android. Strangely, the app doesn't get installed on my Motorola Xoom.

Please note the app runs fine on the device. But when I see the app list on the device I can't find my app.

Manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.mycamapp"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-feature android:name="android.hardware.camera" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.mycamapp.CameraActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
                <data android:mimeType="image/*" />

            </intent-filter>
        </activity>
    </application>
</manifest>

I have tried some other sample apps(hello world!! kind of examples) and they get installed on my device just fine.

I do not see any apk install message when I run from eclipse. Can anyone advise, what is going wrong with the app?

I would guess the issue is with the <intent-filter> of your CameraActivity . All present elements have to match, and I guess the launcher does not have a image mimeType in its intents ;)

Remove the <data> element from your <intent-filter> , or move it to another one, and the icon should appear. You can have several intent filters for the same activity.
