B4A Library DrawView

A shortcut wrap for this Github project. Posting:
1. B4A sample project (b4aDrawView.zip)
2. B4A library files - copy them to your additional library folder (DrawViewLibFiles.zip)
3. The Java Code - change it to suite your needs
4. Other jar files required - copy them to you additional library folder (OtherJars.zip)
5. resource.zip - extract the folder and copy it to be on the same folder level as that of the /Objects and /Files folder of the B4A project
6. LibRes.zip - extract the folder and copy it to be on the same folder level as that of the /Objects and /Files folder of the B4A project
7. DemoRes.zip - extract the folder and copy it to be on the same folder level as that of the /Objects and /Files folder of the B4A project

You need to enable libs AppCompat (V3.20) and DesignSupport (V2.00) for this to work in B4A V6.00+

Take note of the B4A manifest files.
B4X:
'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: https://www.b4x.com/forum/showthread.php?p=78136

<supports-screens android:largeScreens="true"

    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:theme, "@style/MyAppTheme")

'AddManifestText(<uses-feature android:name="android.hardware.camera" />)

'AddManifestText(<uses-feature android:name="android.hardware.camera.flash" />)

AddApplicationText(<activity
            android:name="com.byox.drawviewproject.SplashScreenActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">

        <activity android:name="com.byox.drawviewproject.MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar"/>)
