位图被回收......？

Question

我正在制作游戏的用户界面系统。但我注意到一个奇怪的问题：Bitmap似乎被回收了

我还没有回收任何位图（我将在稍后做）。 但logcat说：

AWS.config(
            :s3_endpoint => '...',
            :access_key_id => '....',
            :secret_access_key => '....'
           )

我从未想过系统可以回收位图。也许我在创建位图时做错了。

E/AndroidRuntime: FATAL EXCEPTION: GLThread 1050

注意：这就是GLTextureManager.Set的作用（稍后我会将GL10编辑为GLES20。）：

public abstract class UIElement {
    private static final String TAG = "UI Element";
    private static final int WH_SCALER = 100;

    private String name;
    private CoreRect rect;
    private int tex;
    private float x, y;
    private float w, h;
    private Bitmap bmp;

    protected UIElement(String Name, float X, float Y, float Width, float Height) {
        name = Name;
        x = X;
        y = Y;
        w = Width;
        h = Height;
        rect = new CoreRect(Width, Height, false);
        bmp = Bitmap.createBitmap((int)(Width * WH_SCALER), (int)(Height * WH_SCALER), Bitmap.Config.ARGB_8888);
        onCreate(bmp);
    }

    public float GetX() {
        return x;
    }

    public float GetY() {
        return y;
    }

    public float GetWidth() {
        return w;
    }

    public float GetHeight() {
        return h;
    }

    public String GetName() {
        return name;
    }

    protected abstract void OnCreate(Bitmap Bmp);
    private void onCreate(Bitmap Bmp) {
        GLTextureManager.Lock();
        OnCreate(Bmp);
        tex = GLTextureManager.Add(Bmp);
        GLTextureManager.Unlock();
    }

    protected void UpdateTexture() {
        Log.d(TAG, "Texture updated");
        GLTextureManager.Set(tex, bmp);
    }

    protected abstract void OnRender(Bitmap Bmp);
    public void Render() {
        //Log.d(TAG, "Render()");
        GLTextureManager.Lock();
        OnRender(bmp);
        rect.Render(x, y, GLTextureManager.Get(tex));
        GLTextureManager.Unlock();
    }
}
