java - 如何以编程方式在 Android 中获取 IMSI 号码

Question

我尝试了以下代码:

private String getImsi() {
   TelephonyManager mTelephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
   return mTelephonyMgr.getSubscriberId();
}

<uses-permission android:name='android.permission.READ_PHONE_STATE' />

但它只返回 null。

有没有其他方法可以在android中用java获取IMSI？

Answer 1

String imei = android.os.SystemProperties.get(android.telephony.TelephonyProperties.PROPERTY_IMSI);

经许可

 android.permission.READ_PHONE_STATE

由于SystemProperties在Android中是一个隐藏类，所以可以通过反射访问它:

/**
 * Get the value for the given key.
 * @return an empty string if the key isn't found
 */
public static String get(Context context, String key) {
    String ret = "";

    try {
        ClassLoader cl = context.getClassLoader(); 
        @SuppressWarnings("rawtypes")
        Class SystemProperties = cl.loadClass("android.os.SystemProperties");

        //Parameters Types
        @SuppressWarnings("rawtypes")
        Class[] paramTypes= new Class[1];
        paramTypes[0]= String.class;

        Method get = SystemProperties.getMethod("get", paramTypes);

        //Parameters
        Object[] params = new Object[1];
        params[0] = new String(key);

        ret = (String) get.invoke(SystemProperties, params);
    } catch(Exception e) {
        ret = "";
        //TODO : Error handling
    }

    return ret;
}
