libGDX: FPS on Android device is low

Question

In my game I have created many loops and methods inside render. The FPS range in my laptop ranges from 56 to 60, which is ok. However, when I run it in the Android OS on a Galaxy Note 4, the range of FPS ranges from 24 to 45, which is not ok.

Now I need a new render thread, to render synchronously with:

Gdx.app.getApplicationListener().render();

Can anyone help me solve this problem?

Even a low end laptop usually has much more processing power than a high end smartphone, thus what performs smoothly on your laptop can lag behind terribly on your Galaxy Note.

You've provided almost no information in the question, so the things I can suggest are general approaches;

• Profile the game on your phone, and find possible bottlenecks, so you can deal with them.

• OpenGL profiling will also be very helpful, you can monitor context switches and more with it.

• Also as a general rule of thumb, do not create new objects in the render loop, or do it as little as possible if absolutely necessary. Initializing a pool of reusable objects at start will help you a lot.
