title: How to get Transparent Animation in AndEngine?
body: <p>I have successfully displayed an animation by using spritesheet(generated using TexturePacker). But when I set transparent background for the scene,it is not working! its displayed with black background. But for the other colors it is displaying the specified colors.</p>
  
  <pre><code>m_Scene.setBackground(new Background(Color.RED));//displayed with red Bg
  
  m_Scene.setBackground(new Background(Color.TRANSPARENT));//displayed with black Bg
  </code></pre>
  
  <p>below is my full method onCreateScene() and my Activity extends SimpleBaseGameActivity</p>
  
  <p>What could be the reason for this issue? can anyone help me to solve this ? </p>
  
  <pre><code>@Override
  protected Scene onCreateScene() {
  
      m_Scene = new Scene();
      m_Scene.setBackground(new Background(Color.TRANSPARENT));
      mTiledTextureRegion = getTiledTextureFromPack("sample");
      mAnimatedSprite = new AnimatedSprite(0, 0, mTiledTextureRegion,
              this.getVertexBufferObjectManager());
      m_Scene.attachChild(mAnimatedSprite);
      mAnimatedSprite.animate(160);
      return m_Scene;
  }
  </code></pre>
  
  <p>I have two activities "FirstActivity" and "SecondActivity".
  "FirstActivity" extends Activity and "SecondActivity" extends SimpleBaseGameActivity.
  What I'm doing is, I'm starting  SecondActivity from FirstActivity on a button click.</p>
  
  <pre><code>   public void onGoButtonCLick(View view) {
  
        startActivity(new IntentFirstActivity.this,SecondActivity.class));
  }
  </code></pre>
  
  <p>and the SecondActivity made as transparent in the manifest </p>
  
  <p><code>android:theme="@android:style/Theme.Translucent"</code></p>
  
  <p>Now the output screen displays transparent in other places but the scene area becomes black if set <code>m_Scene.setBackground(new Background(Color.TRANSPARENT));</code></p>
  
  <p>please check below link to see the output:</p>
  
  <p><code>m_Scene.setBackground(new Background(Color.RED));</code> //displayed with red Bg</p>
