Android如何獲得系統版本

如何獲得Android系統版本

項目移植中,遇到需要區分不同系統版本的問題。於是查找相關方法如下:

 

android.os.Build類提供瞭當前系統信息。

可用if (Build.VERSION.SDK_INT < Build.VERSION_CODES.GINGERBREAD)這樣來判斷。

 

有人用這樣一個函數來獲取版本號:

 

public static int getAndroidSDKVersion() { 

int version; 

try { 

version = Integer.valueOf(android.os.Build.VERSION.SDK); 

} catch (NumberFormatException e) { 

Log.e(e.toString());

return version; 

}

 

android.os.Build.VERSION_CODES 值有如下,其中第二列的值就是API LEVEL編號:

 

int  1 (0x00000001) BASE October 2008: The original, first, version of Android.

int  2 (0x00000001) BASE_1_1 February 2009: First Android update, officially called 1.1.

int  3 (0x00000001) CUPCAKE May 2009: Android 1.5.

int  10000 (0x00002710) CUR_DEVELOPMENT Magic version number for a current development build, which has not yet turned into an official release.

int  5 (0x00000001) DONUT September 2009: Android 1.6.

int   ECLAIR November 2009: Android 2.0

  Applications targeting this or a later release will get these new changes in behavior:

 5 (0x00000008) The Service.onStartCommand function will return the new START_STICKY behavior instead of the old compatibility START_STICKY_COMPATIBILITY.

int  6 (0x00000008) ECLAIR_0_1 December 2009: Android 2.0.1

int  7 (0x00000008) ECLAIR_MR1 January 2010: Android 2.1

int  8 (0x00000008) FROYO June 2010: Android 2.2

int   GINGERBREAD November 2010: Android 2.3

  Applications targeting this or a later release will get these new changes in behavior:

 9 (0x00000009) The application's notification icons will be shown on the new dark status bar background, so must be visible in this situation.

int  10 (0x0000000a) GINGERBREAD_MR1 February 2011: Android 2.3.3.

int  11 (0x0000000b) HONEYCOMB February 2011: Android 3.0.

int  12 (0x0000000c) HONEYCOMB_MR1 May 2011: Android 3.1.

int  13 (0x0000000d) HONEYCOMB_MR2 June 2011: Android 3.2.

int  14 (0x0000000e) ICE_CREAM_SANDWICH October 2011: Android 4.0.

int  15 (0x0000000f) ICE_CREAM_SANDWICH_MR1 December 2011: Android 4.0.3.

int  16 (0x00000010) JELLY_BEAN Android 4.1.
