i making map application on running above mentioned errors displayed in problem section console section.

your problem trying implement google maps api v1, using google maps api v2 key. , can't do.

so should make following changes in code:

1. remove: <uses-library android:name="com.google.android.maps"/>" manifest file, v1 permission.

2. if want support v8 api have remove implementation of activity mapactivity , change fragmentactivity. supporting fragment on older systems.

3. change xml layout file from:

<com.google.android.maps.mapview   android:id="@+id/mymap"   android:layout_width="match_parent"   android:layout_height="match_parent"   android:apikey="aizasybctxeirtszthvlmal5jddc-sk-mw7s_ce"/> 

to this:

<fragment     android:name="com.google.android.gms.maps.supportmapfragment"     xmlns:map="http://schemas.android.com/apk/res-auto"     android:id="@+id/map"     android:layout_width="match_parent"     android:layout_height="match_parent" /> 

4. have add staff in manifest file:

add permissions:

<permission android:name="your.application.package.permission.maps_receive"  android:protectionlevel="signature"/> <uses-permission android:name="your.application.package.permission.maps_receive"/> <uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.write_external_storage"/> <uses-permission android:name="com.google.android.providers.gsf.permission.read_gservices"/> <uses-permission android:name="android.permission.access_coarse_location" /> <uses-permission android:name="android.permission.access_fine_location" />  <uses-feature android:glesversion="0x00020000" android:required="true"/> 

change your.application.package actual application package name.

and add those:

<meta-data android:name="com.google.android.maps.v2.api_key" android:value="your google maps api v2 key" />  <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> 

under application hive.

you can use guide wrote on topic out:

google maps api v2

and go on steps of producing api key , make sure haven't missed thing:

google maps api v2 key
