+ * The DynamicAndroidManager offers a mechanism to use a new Android image temporarily. After the
+ * installation, the device can reboot into this image with a new created /data. This image will
+ * last until the next reboot and then the device will go back to the original image. However the
+ * installed image and the new created /data are not deleted but disabled. Thus the application can
+ * either re-enable the installed image by calling {@link #toggle} or use the {@link #remove} to
+ * delete it completely. In other words, there are three device states: no installation, installed
+ * and running. The procedure to install a DynamicAndroid starts with a {@link #startInstallation},
+ * followed by a series of {@link #write} and ends with a {@link commit}. Once the installation is
+ * complete, the device state changes from no installation to the installed state and a followed
+ * reboot will change its state to running. Note one instance of dynamic android can exist on a
+ * given device thus the {@link #startInstallation} will fail if the device is currently running a
