Programmatically obtain the Android API level of a device?
提问by user283494
How can I find out which API level my device is using?
如何找出我的设备使用的 API 级别？
The firmware version is 1.6. Does that mean it uses API Level 4?
固件版本为 1.6。这是否意味着它使用 API 级别 4？
回答by Arkadiusz Cie?liński
You can obtain API level programatically by the system constant (Build.VERSION.SDK_INT). For example you can run some piece of code which requires newer API in the following way (it will execute if the current device's API level is at least 4)
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：

For API Level >= 4you can use Build.VERSION.SDK_INT
对于API 级别 >= 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)";

Very easy:
好简单：
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
);
Output:

To get your device current API :
要获取您的设备当前 API ：
int MyDeviceAPI = Build.VERSION.SDK_INT;
回答by Jorgesys
in first versions was used Build.VERSION.SDK
在第一个版本中使用 Build.VERSION.SDK
String myAPI= Build.VERSION.SDK;
but now is deprecated!.
但现在已弃用！。
SDKThis field was deprecated in API level 4. Use SDK_INT to easily get this as an integer.
SDK此字段在 API 级别 4 中已弃用。使用 SDK_INT 可轻松将其作为整数获取。
now you have to use: SDK_INTAdded in API level 4 :
现在您必须使用：SDK_INT添加在 API 级别 4 中：
int myAPI = Build.VERSION.SDK_INT;
SDK_INTThe user-visible SDK version of the framework; its possible values are defined in Build.VERSION_CODES.
SDK_INT用户可见的框架 SDK 版本；它的可能值在 Build.VERSION_CODES 中定义。

You can get device's information, as following.
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);
and can get the Android version code history from OS.
并且可以从 OS 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());
}
This is output.
这是输出。
