I figured out what was your poroblem. You were probably trying something like this:

textureView.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {
    @Override
    public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int i, int j) {
        cam.startPreview(surfaceTexture, i, j);
        cam.takePicture();
    }

    public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int i, int i1) { }
    public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) { return false; }
    public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) { }
});
