Loading big models (memory issues)

[iagofg]

I'm also getting that problem relating this, appears that the apk access allows only to objects bellow 1MB in size... here is my exception:

Seems the cause is on:
09-10 22:17:57.676: DEBUG/asset(373): Data exceeds UNCOMPRESS_DATA_MAX (4071780 vs 1048576)

What I don't understand is why the serialized file is so big (I yet put it on reduced mode and the source .obj files total size are less than 2mb, with all the geometry and wavefront files waste a lot of space, I also merged the geometry for generate animation like in http://www.jpct.net/wiki/index.php/Loading_3ds_Keyframes_from_Blender but with obj files.

Maybe there is something else to do? (the model is yet reduced).

I'm thinking on implement my own stream filter to store in parts the big serialized file...

I've workaround yet my own InputStream child class that loads model form splitted file successfully.

It is a minefield test-only yet, but works and perhaps helps someone (I tried with BufferedInputStream but Loader seems not to be compatible):

   //zp = Loader.loadSerializedObject(res.openRawResource(R.raw.zpmodel));
   zp = Loader.loadSerializedObject(new MyModelStream());
   
   [...]
   
   class MyModelStream extends java.io.InputStream {
      private int i = 0;
      private java.io.InputStream s = null;
      private void changestream() {
         ++i;
         //Log.v(TAG, "MyModelStream reading resource file no. " + i);
         if (i == 1) s = getResources().openRawResource(R.raw.zpmodel_aa);
         if (i == 2) s = getResources().openRawResource(R.raw.zpmodel_ab);
         if (i == 3) s = getResources().openRawResource(R.raw.zpmodel_ac);
         if (i == 4) s = getResources().openRawResource(R.raw.zpmodel_ad);
      }
      public int available() throws IOException {
         if (s == null) changestream();
         if (s == null) return 0;
         int v = s.available();
         if (v <= 0) { // needs to change stream here also for Loader compat
            //Log.v(TAG, "MyModelStream.available returns <= 0, next block and requesting again...");
            changestream();
            v = s.available();
         }
         //Log.v(TAG, "MyModelStream.available returns " + v);
         return v;
      }
      public void close() throws IOException {
         if (s == null) changestream();
         if (s == null) return;
         //Log.v(TAG, "MyModelStream.close has been called");
         s.close();
      }
      public void mark(int readlimit) {
         //Log.v(TAG, "MyModelStream.mark has been called");
         return;
      }
      public boolean markSupported() {
         boolean v = false;
         //Log.v(TAG, "MyModelStream.markSupported returns " + v);
         return v;
      }
      public int read() throws IOException {
         if (s == null) changestream();
         if (s == null) return -1;
         int v = s.read();
         if (v < 0) {
            //Log.v(TAG, "MyModelStream.read returns < 0, next block and reading again...");
            changestream();
            v = s.read();
         }
         //Log.v(TAG, "MyModelStream.read returns " + v + " bytes");
         return v;
      }
      public int read(byte[] b) throws IOException, NullPointerException {
         if (s == null) changestream();
         if (s == null) return -1;
         int v = s.read(b);
         if (v < 0) {
            //Log.v(TAG, "MyModelStream.read returns < 0, next block and reading again...");
            changestream();
            v = s.read(b);
         }
         //Log.v(TAG, "MyModelStream.read returns " + v + " bytes");
         return v;
      }
      public int read(byte[] b, int off, int len) throws IOException, NullPointerException {
         if (s == null) changestream();
         if (s == null) return -1;
         int v = s.read(b, off, len);

            v = s.read(b, off, len);
         }

         return v;
      }
      public void reset() throws IOException {
         //Log.v(TAG, "MyModelStream.reset has been called");
         throw new IOException();
      }
      public long skip(long n) throws IOException {

         long v = s.skip(n);
         //Log.v(TAG, "MyModelStream.skip returns " + v);
         return v;
      }
   }

Just rename the file to .mp3 and these restrictions will go away.
