Oh, i hava found the reason: 

I used a debug-version-apk, it run slow. If i use release version, then run fast.

Hi all:

  I download Ninja demo, which provided a demo-apk and demo-src.

  First, i installed demo-apk on my phone, it run fast.(40 fps avg in mesh and skin animation).
  Then i import demo-src-project in eclipse,  build and installed on my phone, it run very slow!(only 3-8 fps in mesh animation).

   Why?
 
   There are what i did with the demo-src :

   1, import ninja-demo-src-project in eclipse.
   2, download Bone-api-src, and import it in ninja-demo-src-project.
   3, delete package: raft\jpct\bones\util,  delete raft\jpct\bones\BonesImporter.java
   4, set android-sdk-version: 2.3.3
   5, use jpct-ae-1.23-beta.jar which is included by ninja demo.
   
And when i entry Ninja-demo(src-build-demo),  the loading time is very long(1 minute), log-cat:

Thanks!

I like Jpct-AE  because of its simple and performance. And there is another question:
 
  I tried JME3(Jmonkey) engine, to do the same thing, use the same texture(2048*2048) and the same obj、mtl and the same phone，but didn't crash.

  Is there any difference between  Jpct-AE and JME3 (to handle texture)?

 

Hi all:

  I used a 2048*2048 jpg for texture, then app crashed. Android-logcat info like this:

  My code:
       
 
       //onSurfaceChanged
      Options options = new Options();
      options.inScaled = false;
      Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.raw.texture, options);
      Texture texture2 = new Texture(bitmap);

     TextureManager.getInstance().addTexture("m", texture2);
      cube.setTexture("m");
      world.addObject(cube);


Can anyone tell me why? And how to resolve it? Why "new Texture(bitmap);" didn't crashed but "World.draw" creashed?

If i use a smaller jpg for texture, then all  are ok.
