Your logcat clearly said
03-04 01:25:23.293: E/AndroidRuntime(19467): Caused by:
java.lang.IllegalStateException: The meta-data tag in your app's
AndroidManifest.xml does not have the right value. Expected 4242000
but found 0. You must have the following declaration within the
<application> element: <meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" /> 03-04
01:25:23.293: E/AndroidRuntime(19467):
Add the Google Play services version to your app's manifest
Edit your application's AndroidManifest.xml file, and add the following declaration within the element. This embeds the version of Google Play services that the app was compiled with.
You need to add <meta-data> under <application> tag into your AndroidManifest.xml
....<application>
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
</application>
This is because latest google play services requires a version name, which is to be mentioned using <meta-data .. /> inside AndroidManifest.xml
and also change MainActivity extends Activity
For more information go to :https://developers.google.com/maps/documentation/android
回答2:
if you are using android-support-v4.jar (for backward support) then try SupportMapFragment
replace this line class="com.google.android.gms.maps.MapFragment"
with class="com.google.android.gms.maps.SupportMapFragment"
and also put in manifest.xml
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="YOUR_API_KEY" />
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

I think your package name and the permission tag package names are differing I think and even this android:name="com.appscourt.jooging.track.map.health.MainActivity" try to verify
