Time for action – decoding a camera's feed


Let's write the necessary Java code to record and display pictures in a fresh new project:

  1. Create a new hybrid Java/C++ project as shown in Chapter 2, Starting a Native Android Project:

    • Name it LiveCamera

    • The main package is com.packtpub.livecamera

    • The main activity is LiveCameraActivity

    • The main activity layout name is activity_livecamera

    • Use the Blank Activity template

  2. Once created, turn the project into a native project as already seen. In the AndroidManifest.xml file, request access permission to the camera. Then, set the activity style to fullscreen and its orientation to landscape. Landscape orientation avoids most camera orientation problems that are met on Android devices:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.packtpub.livecamera"
      android:versionCode="1" android:versionName="1.0" >
      <uses-sdk android:minSdkVersion="14" android:targetSdkVersion...
