我有一個GLSurfaceView和一個渲染器，它在onSurfaceCreated中加載紋理。我的紋理創建像這樣：加載大紋理時內存溢出
public Texture3D(final GL10 gl, final int id) {
_pBitmap = BitmapFactory.decodeResource(Utils.getResources(), id);
gl.glEnable(GL10.GL_TEXTURE_2D);
gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST);
texture = newTextureID(gl);
gl.glBindTexture(GL10.GL_TEXTURE_2D, texture);
gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE);
gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE);
gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR);
gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);
gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA);
GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, _pBitmap, 0);
_pBitmap.recycle();
_pBitmap = null;
gl.glEnable(GL10.GL_BLEND);
}
我把它們存儲在一個HashMap中：
textures.put(R.drawable.tile, new Texture3D(gl, R.drawable.tile));
我的問題是，當我創建一個大的圖像（720x1280，561 KO）紋理後
我有時會以下錯誤：04-24 11:05:19.870: D/dalvikvm(27953): GC_CONCURRENT freed 26K, 18% free 50397K/60743K, paused 18ms+6ms, total 57ms

指向哪裏使用BitmapFactory.decodeResource構造函數的第一行。在我的Galaxy S3上，當我切換到另一個片段時出現錯誤，然後我回到顯示GLSurfaceView（0123'98和onResume在GLSurfaceView上被調用）的片段。
我該如何避免這個問題？我嘗試了this solution，但是我失去了太多的質量，並且在很少的情況下無論如何都會發生錯誤（可能在舊手機型號上）。
如何創建/存儲我的紋理有什麼問題嗎？你也知道爲什麼我不總是得到這個錯誤嗎？ （通常我第二次加載紋理時就會得到它）。
嘗試增加VM堆的大小。希望這會幫助你解決你的問題... – 2013-04-25 07:18:41
我建議，嘗試用MAT分析內存。 http://www.eclipse.org/mat/ – 2013-04-25 07:55:17
