如何找出我的设备使用的API级别？
固件版本为1.6。这是否意味着它使用API级别4？
答案 0 :(得分：91)
您可以通过系统常量（Build.VERSION.SDK_INT）以编程方式获取API级别。例如，您可以通过以下方式运行一些需要更新API的代码（如果当前设备的API级别至少为4，它将执行）
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.DONUT) {
}
要获取用户可见的Android版本，请使用：
Build.VERSION.RELEASE

答案 2 :(得分：8)
对于 API级别＆gt; = 4 ，您可以使用 Build.VERSION.SDK_INT
private String getAndroidVersion(int sdk) {
switch (sdk) {
case 1: return "(Android 1.0)";
case 2: return "Petit Four" + "(Android 1.1)";
case 3: return "Cupcake" + "(Android 1.5)";
case 4: return "Donut" + "(Android 1.6)";
case 5: return "Eclair" + "(Android 2.0)";
case 6: return "Eclair" + "(Android 2.0.1)";
case 7: return "Eclair" + "(Android 2.1)";
case 8: return "Froyo" + "(Android 2.2)";
case 9: return "Gingerbread" + "(Android 2.3)";
case 10: return "Gingerbread" + "(Android 2.3.3)";
case 11: return "Honeycomb" + "(Android 3.0)";
case 12: return "Honeycomb" + "(Android 3.1)";
case 13: return "Honeycomb" + "(Android 3.2)";
case 14: return "Ice Cream Sandwich" + "(Android 4.0)";
case 15: return "Ice Cream Sandwich" + "(Android 4.0.3)";
case 16: return "Jelly Bean" + "(Android 4.1)";
case 17: return "Jelly Bean" + "(Android 4.2)";
case 18: return "Jelly Bean" + "(Android 4.3)";
case 19: return "KitKat" + "(Android 4.4)";
case 20: return "KitKat Watch" + "(Android 4.4)";
case 21: return "Lollipop" + "(Android 5.0)";
case 22: return "Lollipop" + "(Android 5.1)";
case 23: return "Marshmallow" + "(Android 6.0)";
case 24: return "Nougat" + "(Android 7.0)";
case 25: return "Nougat" + "(Android 7.1.1)";
case 26: return "Oreo" + "(Android 8.0)";
case 27: return "Oreo" + "(Android 8.1)";
case 28: return "Pie" + "(Android 9.0)";
default: return "";
}
}
<强>用法
String android_os = getAndroidVersion(android.os.Build.VERSION.SDK_INT);
答案 3 :(得分：4)
String manufacturer = Build.MANUFACTURER;
String model = Build.MODEL;
int version = Build.VERSION.SDK_INT;
String versionRelease = Build.VERSION.RELEASE;
Log.e("MyActivity", "manufacturer " + manufacturer
+ " \n model " + model
+ " \n version " + version
+ " \n versionRelease " + versionRelease
);
E/MyActivity: manufacturer samsung
model SM-T310
version 19
versionRelease 4.4.2
答案 4 :(得分：3)
要获取设备当前的API：
int MyDeviceAPI = Build.VERSION.SDK_INT;
答案 5 :(得分：3)
使用了Build.VERSION.SDK
String myAPI= Build.VERSION.SDK;
但现已弃用！
SDK 此字段在API级别4中已弃用。轻松使用SDK_INT 得到这个整数。
int myAPI = Build.VERSION.SDK_INT;
SDK_INT 框架的用户可见SDK版本;这是可能的 值在Build.VERSION_CODES中定义。

您可以获取设备的信息，如下所示。
Log.d(TAG, "RELEASE : " + Build.VERSION.RELEASE);
Log.d(TAG, "SDK : " + Build.VERSION.SDK_INT);
并且可以从操作系统获取Android版本代码历史记录。
for (Field field : Build.VERSION_CODES.class.getDeclaredFields()) {
field.setAccessible(true);
Log.d(TAG, field.get(this) + " -> " + field.getName());
}
这是输出。
RELEASE : 5.1.1
SDK : 22
1 -> BASE
2 -> BASE_1_1
3 -> CUPCAKE
10000 -> CUR_DEVELOPMENT
4 -> DONUT
5 -> ECLAIR
6 -> ECLAIR_0_1
7 -> ECLAIR_MR1
8 -> FROYO
9 -> GINGERBREAD
10 -> GINGERBREAD_MR1
11 -> HONEYCOMB
12 -> HONEYCOMB_MR1
13 -> HONEYCOMB_MR2
14 -> ICE_CREAM_SANDWICH
15 -> ICE_CREAM_SANDWICH_MR1
16 -> JELLY_BEAN
17 -> JELLY_BEAN_MR1
18 -> JELLY_BEAN_MR2
19 -> KITKAT
20 -> KITKAT_WATCH
21 -> L
21 -> LOLLIPOP
22 -> LOLLIPOP_MR1
所以，将这些和official version list结合起来。
API VERSION_CODE VERSION CODE_NAME
1 BASE 1 (no code name)
2 BASE_1_1 1.1 (no code name)
3 CUPCAKE 1.5 Cupcake
4 DONUT 1.6 Donut
