An android-based automatic resolution adjustment method and system

Abstract

The invention provides an Android-based resolution ratio automatic adjustment method. The Android-based resolution ratio automatic adjustment method includes the steps of (10) an initial blank area of an Android file system is divided to form a storage sector; (20) data in the storage sector are read through a BootLoader procedure to be transmitted to an inner core; (30) the inner core valuates the historical resolution ratio to a CPU output the resolution ratio; (40) the optimum resolution ratio of a current external displayer is obtained through a display driver to be written into the storage sector; (50) whether the historical resolution ratio is coincident with the optimum resolution ratio of the current external displayer or not is judged, the step (60) is executed if the historical resolution ratio is coincident with the optimum resolution ratio of the current external displayer, or the step (20) is repeatedly executed; (60) the CPU output resolution ratio is valuated to display-size of an Android framework layer. The invention further provides an Android-based resolution ratio automatic adjustment system; and the Android-based resolution ratio automatic adjustment system can be automatically suitable for display scales of different external displayers.

Description

technical field

[0001] The invention relates to an Android-based resolution automatic adjustment method and system. Background technique

[0002] The Android (Android) system is an open source operating system based on the Linux platform. It is currently widely used in smart portable digital devices such as mobile phones and tablets. With the increasing maturity of Android office applications, Android devices are also developing towards office terminals. , from a single touch screen output to a more diverse external display output. Because the Android system was designed based on a single touch screen output, the kernel has fixed a fixed output ratio and cannot be modified. For example, the screen resolution of a common mobile phone is 480*800, and the screen resolution of a tablet is 1920*1080. If Once such a fixed output display ratio is connected to a VGA / HDMI display with an inconsistent ratio, the overall picture will be stretched or squeezed, which cannot meet the acc...
