试试这个:

 if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.GINGERBREAD) {
     // only for gingerbread and newer versions
 }

很简单:

   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
    );

输出:

E/MyActivity:   manufacturer ManufacturerX
                model SM-T310 
                version 19 
                versionRelease 4.4.2

是这样的:

String versionRelease = BuildConfig.VERSION_NAME;

versionRelease :- 2.1.17

请确保您的导入包是正确的(导入包your_application_package_name，否则将无法正常工作)。

SDK。INT支持Android 1.6及以上版本

所有版本都支持SDK

所以我这样做:

String sdk_version_number = android.os.Build.VERSION.SDK;

试试这个:

 if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.GINGERBREAD) {
     // only for gingerbread and newer versions
 }

明白了。它使用Context类的getApplicationInfo()方法。
