Question

In this project i got some run time error which i tired it to resolve it by pasting the error in the google and get the appropriate result for that. But am not able to solve that and

and other code of that is fine But manifest file is showing some warning.And the code is

`<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.collabera.labs.sai.maps"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <uses-library android:name="com.google.android.maps" />

        <activity android:name=".SampleMapActivity"
                  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>
    <uses-sdk android:minSdkVersion="3" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

</manifest> `

and it is showing some warning in the first line and that is "Attribute minSdkVersion (3) is lower than the project target API level (8)"

    />


</LinearLayout>

thanks in advance

Answer 1

Create a Emulitor and set Target as Google And not as Android. :)

Answer 2

use google API 1.6 or more then for developing map application not android API.

 <uses-sdk android:minSdkVersion="7" /> or  <uses-sdk android:minSdkVersion="8" />

Answer 3

Is there any reason why you want to use SDK version 3? I would recommend at least 7 or 8..

         <uses-sdk 
          android:minSdkVersion="7" 
          android:targetSdkVersion="7"
         />
