.apk file not working on device

Question

Hi, i took an android project and imported it in eclipse. in properties->android section it is showing platform 1.6 and API level 4. I have downloaded Android 2.2. Now when i try to make some changes in the source code and make an .apk file and try to install on my android device the device shows an error : Application not installed. the project is not showing any error but it is showing a warning : Attribute minSdkVersion (3) is lower than the project target API level (4) in manifest file. the person who gave me th eproject i asked him to mail his .apk file to me and that .apk file is running perfectly on the device. Please advice.

Answer 1

Change to API level 3 (Android 1.5), that must be the solution. you must have in your manifest.xml defined a minSdkVersion = 3

    </application>    

    <uses-sdk android:minSdkVersion="3" />

</manifest> 

or change the minSdkVersion to Api level 4 at your manifest.xml file that correspond to android 1.6

    </application>    

    <uses-sdk android:minSdkVersion="4" />

</manifest> 

build, create and sign your .apk again
