Question

I’ve built an app that runs fine on the emulators, and says that it installs ok on the phone. However, on trying to run it an error pops up saying ‘Application is not installed on your phone’. So I tried running the app through eclipse on the phone and I got this error in the console:

[2012-05-01 12:00:02 - MAD Assignment] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.mad.assignment/.MainMenu }
[2012-05-01 12:00:02 - MAD Assignment] ActivityManager: java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.mad.assignment/.MainMenu } from null (pid=8204, uid=2000) requires null

From looking for the solution elsewhere it sounds as though it could be a problem in the manifest file, so here is mine:

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

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

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" 
     >
    <activity
        android:name="MainMenu"
        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=".Diary"></activity>
    <activity android:name=".Info"></activity>
    <activity android:name=".MapMenu"></activity>
    <activity android:name=".RSSMenu"></activity>
    <activity android:name=".RSSFeedView"></activity>
    <activity android:name=".MainMenu"></activity>
    <activity android:name=".RSSDetailed"></activity>
    <activity android:name=".DiarySchedule"></activity>
    <activity android:name=".DiaryAddEntry"></activity>
    <activity android:name=".DiaryEditEntry"></activity>
    <activity android:name=".DiaryDetailed"></activity>
    <activity android:name=".RSSDetailed"></activity>
    <uses-library android:name="com.google.android.maps"/>
    <activity android:name=".MapMain"></activity>
    <activity android:name=".RSSFeedView"></activity>
    <activity android:name=".MapWhatsNearPreferences"></activity>
    <activity android:name=".RoutePath"></activity>
</application>

Any ideas what this security exception is pointing to? Thanks!

Answer 1

The java.lang.SecurityException you are seeing is because you may enter two entries pointing to same activity. Remove the second one and you should be good to go.

You may be declared the activity 2 times in the manifest with different properties, like :

 <activity android:name=".MainMenu"> </activity>

and

 <activity android:name=".MainMenu" android:label="@string/app_name"> 
     <intent-filter> 
         <action android:name="android.intent.action.MAIN" />
         <category android:name="android.intent.category.LAUNCHER" />
     </intent-filter>
 </activity>

You should remove the unwanted one from the manifest
