Membuat aplikasi kamera di Android
Seperti biasa, membuat project android baru. Disini IDE nya saya menggunakan Eclipse ADT Bundle, dimana IDE Eclipse sudah id-bundling menjadi satu paket dengan SDK android terbaru beserta ADT-nya.


  

Coding Dari Aplikasi ini :

-Activity.xml-
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <//Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="42dp"
        android:text="Set As Wallpaper" />

    <//Button
        android:id="@+id/btn_pilih"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/button1"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="14dp"
        android:text="Ambil Gambar" />

    <//ImageView
        android:id="@+id/imageView1"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="10dp"
        android:src="@drawable/icon" />
