Question

I’m trying to make an Android maps app. As I’m new to all this I’m fiddling around with the basics so I decided to create a map, show a button and digital clock.

When I run the project the emulator loads however when it tries to load the app it force closes.

My main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <DigitalClock android:text="@+id/DigitalClock01"
        android:id="@+id/DigitalClock01"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"></DigitalClock>
    <Button android:text="@+id/Button01"
        android:layout_width="wrap_content"
        android:id="@+id/Button01"
        android:layout_height="wrap_content"></Button>
    <com.google.android.maps.MapView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:apiKey="xyz_my_key" />
</LinearLayout>

In my manifest I have added the uses-library definition

  <uses-library android:name="com.google.android.maps"/>

and I have also added the internet usage permission

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

Why is it crashing?

last entry from error log:

No command output when running: ‘am
