- * The per-process memory overhead of hardware accelerated graphics can
- * be quite large on some devices. For small memory devices, being able to
- * terminate all EGL contexts so that this graphics driver memory can be
- * reclaimed can significant improve the overall behavior of the device. This
- * class helps app developers participate in releasing their EGL context
- * when appropriate and possible.
- *
- * <p>To use, simple instantiate this class with the EGLContext you create.
- * When you have done this, if the device is getting low on memory and all
- * of the currently created EGL contexts in the process are being managed
- * through this class, then they will all be asked to terminate through the
- * call to {@link #onTerminate}.
