买了个新手机，应用又崩溃了，连上电脑看catlog，报错：java.lang.ArrayIndexOutOfBoundsException。

java 复制代码

 String APV[] = new String[] {
            "",

            "Android 7.0, Nougat, 201608",
            "Android 7.1.1, Nougat, 201610",

            "Android 12, Snow Cone, 20211005"
};

String s = APV[android.os.Build.VERSION.SDK_INT];

复制代码

android.os.Build.VERSION.SDK_INT，3年多前的旧手机=31，新手机=36，超过范围直接崩溃。

使用Map取不到值="null"，不会崩溃。

java 复制代码

HashMap<Integer, String> map_APV;

map_APV = new HashMap<>();
for (int i=0; i<APV.length; i++) {
    map_APV.put(i, APV[i]);
}

String s = map_APV.get(android.os.Build.VERSION.SDK_INT);
