OpenGL ES 2.0 Fix object on the screen

I’m trying to paint a 2D object using OpenGL ES 2.0 in Android Studio, using the Java programming language.

I cannot paint the object in the place I want from the screen (in the real world, the object is in a longitude and latitude and I know the bearing, azimuth, pitch and roll angles).

Also, if I use Matirx.translateM (…) to move the object a random position, it follows me when I move the camera of the Smartphone and it doesn’t stay fixed.

Can you help me with these problems? I do not know how to solve it
