Question

When I try to install my application on my phone it says “Application not installed”

Here is the code of my manifest file :

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

<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<application
    android:name=".TaskLiteApplication"
    android:label="@string/app_name" >
    <activity
        android:name="activity.TaskLiteActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="activity.PrefsActivity" />
    <activity android:name="activity.ToDoActivity" />
    <activity android:name="activity.ProjectActivity" />
    <activity android:name="activity.TaskActivity"/>
    <activity android:name="activity.TabLayoutActivity" 
        android:theme="@style/taskLiteTheme"/>
    <service android:name="service.UpdaterService"></service>
</application>
</manifest>

EDIT: It’s fix, the apk needed to be signed, i didn’t had to change anything in the manifest file thank you

Answer 1

Usually that means a few things.

1. Are you installing this from eclipse onto a device? If so, have a look at your adb logcat output.
2. Are you installing an exported, signed application from eclipse onto a device through email or a browser download? Then make sure you have Unknown sources enabled in Settings > Applications
