以编程方式获取设备的Android API级别？

Question

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？

Answer 1

您可以通过系统constant(Build.VERSION.SDK_INT)以编程方式获取API级别.例如,你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

Answer 3

对于API Level> = 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)";
        case 29: return  "Android 10"          + "(Android 10.0)";
        default: return  "";
    }
}

用法

String android_os = getAndroidVersion(android.os.Build.VERSION.SDK_INT);

Answer 4

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
     );

输出：

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