我正在开发一个
Android应用程序,我将使用LVL库来检查Google Play许可证.
阅读LVL文档后,我已经看到我必须获取android.Settings.Secure.ANDROID_ID以模糊谷歌播放响应.
但是我也读到从TelephonyManager获得的ANDROID_ID有时是不同的设备相同的.
First,it is not 100% reliable on releases of Android prior to 2.2 (“Froyo”). Also,there has been at least one widely-observed bug in a popular handset from a major manufacturer,where every instance has the same ANDROID_ID
真的吗？
谢谢
解决方法
考虑我的情况：
Same serial number on several android devices. Adb is useless. How can I change the serial number?
所以我没有解决ADB的问题,而是识别一个Android设备我使用这个代码(使用getDeviceId(上下文))：
public static String getDeviceId(Context context) {
String id = getUniqueID(context);
if (id == null)
id = Settings.Secure.getString(context.getContentResolver(),Settings.Secure.ANDROID_ID);
return id;
}
private static String getUniqueID(Context context) {
String telephonyDeviceId = "NoTelephonyId";
String androidDeviceId = "NoAndroidId";
// get telephony id
try {
final TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
telephonyDeviceId = tm.getDeviceId();
if (telephonyDeviceId == null) {
telephonyDeviceId = "NoTelephonyId";
}
} catch (Exception e) {
}
// get internal android device id
try {
androidDeviceId = android.provider.Settings.Secure.getString(context.getContentResolver(),android.provider.Settings.Secure.ANDROID_ID);
if (androidDeviceId == null) {
androidDeviceId = "NoAndroidId";
}
} catch (Exception e) {
}
// build up the uuid
try {
String id = getStringIntegerHexBlocks(androidDeviceId.hashCode())
+ "-"
+ getStringIntegerHexBlocks(telephonyDeviceId.hashCode());
return id;
} catch (Exception e) {
return "0000-0000-1111-1111";
}
}
public static String getStringIntegerHexBlocks(int value) {
String result = "";
String string = Integer.toHexString(value);
int remain = 8 - string.length();
char[] chars = new char[remain];
Arrays.fill(chars,'0');
string = new String(chars) + string;
int count = 0;
for (int i = string.length() - 1; i >= 0; i--) {
count++;
result = string.substring(i,i + 1) + result;
if (count == 4) {
result = "-" + result;
count = 0;
}
}
if (result.startsWith("-")) {
result = result.substring(1,result.length());
}
return result;
}
在使用Web服务时,我可以使用它来识别特定的应用安装.您可以看到我尝试不同的审批,也基于TelephonyManager和ANDROID_ID.
我得到的是像xxxx-xxxx-xxxx-xxxx这样的字符串,其中x是一个十六进制字符.
我买了很多低成本的中国平板电脑,所有这些都具有相同的DEVICE_ID和相同的序列号！所以我的解决方案现在工作很好
