android - Sprites appear as white boxes -

i have simple libgdx application 2 sprites. 1 simple texture repeated fill background. 1 works. other texture alpha blended corners darker center. stretched cover entire screen. reason, 1 appears in wrong location , big white box.

here code:

public class testgame extends applicationadapter {     spritebatch batch;     boolean showingmenu;     texture background;     sprite edgeblur;     texture edgeblurtex;      @override     public void create() {         showingmenu = true;          batch = new spritebatch();         background = new texture(gdx.files.internal("blue1.png"));         edgeblurtex = new texture(gdx.files.internal("edge_blur.png"));         edgeblur = new sprite(edgeblurtex);         edgeblur.setsize(gdx.graphics.getwidth(), gdx.graphics.getheight());     }      @override     public void resize(int width, int height) {         super.resize(width, height);         edgeblur.setsize(width, height);     }      @override     public void dispose() {         background.dispose();         edgeblurtex.dispose();         super.dispose();     }      @override     public void render() {         gdx.gl.glclearcolor(0, 0, 0, 1);         gdx.gl.glclear(gl20.gl_color_buffer_bit);          batch.begin();          drawbackground();          batch.end();     }      private void drawbackground() {         (float x = 0; x < gdx.graphics.getwidth(); x += background.getwidth()) {             (float y = 0; y < gdx.graphics.getheight(); y += background.getheight()) {                 batch.draw(background, x, y);             }         }          edgeblur.draw(batch);     } } 

edit:

i fixed changing draw command to:

batch.draw(edgeblurtex, 0, 0, gdx.graphics.getwidth(), gdx.graphics.getheight()); 

however if attempt drawing after drawing these textures, such as:

    shaperenderer shaperenderer = new shaperenderer();      shaperenderer.begin(shaperenderer.shapetype.line);     shaperenderer.setcolor(0, 0, 0, 1);      float unitheight = gdx.graphics.getheight() / 9;     float indent = gdx.graphics.getwidth() / 20;      shaperenderer.rect(indent, unitheight, gdx.graphics.getwidth() - indent * 2, unitheight);     shaperenderer.rect(indent, unitheight * 3, gdx.graphics.getwidth() - indent * 2, unitheight);     shaperenderer.rect(indent, unitheight * 5, gdx.graphics.getwidth() - indent * 2, unitheight);     shaperenderer.rect(indent, unitheight * 7, gdx.graphics.getwidth() - indent * 2, unitheight);      shaperenderer.end(); 

it stops working , goes drawing white box. seems random, misconfigured libgdx. there way debug thing work out wrong?

you should add enableblending before blended texture draw

    batch.enableblending();      edgeblur.draw(batch);      batch.disableblending(); 

you can try set batch blending func using setblendfunction method after batch created

update due edit:

the spritebatch should ended when starting shaperenderer
