Android 让第三方获取imei

系统中添加imei到persist.sys.imei系统属性中

if (intent.getAction().equals("android.intent.action.SIM_STATE_CHANGED")) {

String IMEI0 = getImeiOnly(context, 0);
      String IMEI1 = getImeiOnly(context, 1);
      SystemProperties.set("persist.sys.imei0", IMEI0);
      SystemProperties.set("persist.sys.imei1", IMEI1);
        }

  public String getImeiOnly(Context context, int slotId) {
            String imei = "";
            try {
                TelephonyManager manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
                if (manager != null) {
                   imei = manager.getImei(slotId);
                }
            } catch (Exception e) {
            }
            if (TextUtils.isEmpty(imei)) {
                TelephonyManager telephonyManager =
                        (TelephonyManager) context.getApplicationContext().getSystemService(Context.TELEPHONY_SERVICE);
                String imeiOrMeid  = telephonyManager.getDeviceId(slotId);//getDeviceId(context, slotId);
                if (!TextUtils.isEmpty(imeiOrMeid) && imeiOrMeid.length() >= 15) {
                    imei = imeiOrMeid;
                }
            }
            return imei;
        }

第三方应用就可以通过SystemProperties.get来获取，SystemProperties可以用反射来调用

package com.unitech.dmitest;

import java.lang.reflect.Method;

public class PropertyUtils {

    private static volatile Method set = null;
    private static volatile Method get = null;

    public static void set(String prop, String value) {

        try {
            if (null == set) {
                synchronized (PropertyUtils.class) {
                    if (null == set) {
                        Class<?> cls = Class.forName("android.os.SystemProperties");
                        set = cls.getDeclaredMethod("set", new Class<?>[]{String.class, String.class});
                    }
                }
            }
            set.invoke(null, new Object[]{prop, value});
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }


    public static String get(String prop, String defaultvalue) {
        String value = defaultvalue;
        try {
            if (null == get) {
                synchronized (PropertyUtils.class) {
                    if (null == get) {
                        Class<?> cls = Class.forName("android.os.SystemProperties");
                        get = cls.getDeclaredMethod("get", new Class<?>[]{String.class, String.class});
                    }
                }
            }
            value = (String) (get.invoke(null, new Object[]{prop, defaultvalue}));
        } catch (Throwable e) {
            e.printStackTrace();
        }
        return value;
    }
}
