If you're into 3D modeling or have received an OBJ file that you want to view on your Android device, you may be wondering how to go about it. Fortunately, there are a few simple ways to open OBJ files on Android.

One of the easiest ways to open an OBJ file on your Android device is to use a dedicated 3D modeling app. Some popular options include GOMANDO, 3D Viewer, and MeshLab. These apps allow you to import and view OBJ files with ease, and some even offer additional features like editing and annotations.

Another option is to use a file viewer app that supports OBJ files. Apps like File Viewer for Android or Autodesk A360 allow you to open and view a wide range of file types, including OBJ files. Simply open the file viewer app, navigate to the location of the OBJ file, and tap to open and view it.

If you want to integrate OBJ file viewing into your own app, you can use a 3D graphics library like Rajawali or JPCT. These libraries provide tools and resources for rendering 3D models, including OBJ files, within your app. With a bit of coding, you can create a custom 3D viewer right within your Android app.

In addition, you can also consider converting the OBJ file to a more widely supported format like FBX or STL. There are online converters available that can quickly and easily convert OBJ files into other formats that may be easier to open and view on your Android device.

Overall, opening OBJ files on Android is relatively straightforward thanks to the variety of apps and tools available. Whether you prefer to use a dedicated 3D modeling app, a file viewer app, or integrate OBJ file viewing into your own app, there are options to suit your needs. And if all else fails, converting the OBJ file to a different format can provide a workaround for viewing the file on your Android device.
