## 获取Google Advertising ID作为唯一识别码 ##

在Android程序中，有时候我们APP需要获取唯一识别码，来区别用户。在Android系统中提供了了AndroidId，但AndroidId有时候会为null，同时root手机用户，androidid可以改变。所以AndroidId并不能作为唯一识别码。

对于Google推荐使用Google Advertising ID，通过Google Service可以获取Google Advertising ID（如果没有Google Service就回去不到Google Advertising ID）。下面看看代码吧

AdvertisingIdClient类

public class AdvertisingIdClient { 
        /** * 这个方法是耗时的，不能在主线程调用 */
        public static String getGoogleAdId(Context context) throws Exception {
            if (Looper.getMainLooper() == Looper.myLooper()) {
                return "Cannot call in the main thread, You must call in the other thread";
            }
            PackageManager pm = context.getPackageManager();
            pm.getPackageInfo("com.android.vending", 0);
            AdvertisingConnection connection = new AdvertisingConnection();
            Intent intent = new Intent(
                    "com.google.android.gms.ads.identifier.service.START");
            intent.setPackage("com.google.android.gms");
            if (context.bindService(intent, connection, Context.BIND_AUTO_CREATE)) {
                try {
                    AdvertisingInterface adInterface = new AdvertisingInterface(
                            connection.getBinder());
                    return adInterface.getId();
                } finally {
                    context.unbindService(connection);
                }
            }
            return "";
        }
    
        private static final class AdvertisingConnection implements ServiceConnection { 
            boolean retrieved = false;
            private final LinkedBlockingQueue<IBinder> queue = new LinkedBlockingQueue<>(1);
    
            public void onServiceConnected(ComponentName name, IBinder service) {
                try {
                    this.queue.put(service);
                } catch (InterruptedException localInterruptedException) {
                }
            }
    
            public void onServiceDisconnected(ComponentName name) {
            }
    
            public IBinder getBinder() throws InterruptedException {
                if (this.retrieved)
                    throw new IllegalStateException();
                this.retrieved = true;
                return this.queue.take();
            }
        }
    
        private static final class AdvertisingInterface implements IInterface { 
            private IBinder binder;
    
            public AdvertisingInterface(IBinder pBinder) {
                binder = pBinder;
            }
    
            public IBinder asBinder() {
                return binder;
            }
    
            public String getId() throws RemoteException {
                Parcel data = Parcel.obtain();
                Parcel reply = Parcel.obtain();
                String id;
                try {
                    data.writeInterfaceToken("com.google.android.gms.ads.identifier.internal.IAdvertisingIdService");
                    binder.transact(1, data, reply, 0);
                    reply.readException();
                    id = reply.readString();
                } finally {
                    reply.recycle();
                    data.recycle();
                }
                return id;
            }
    
            public boolean isLimitAdTrackingEnabled(boolean paramBoolean)
                    throws RemoteException {
                Parcel data = Parcel.obtain();
                Parcel reply = Parcel.obtain();
                boolean limitAdTracking;
                try {
                    data.writeInterfaceToken("com.google.android.gms.ads.identifier.internal.IAdvertisingIdService");
                    data.writeInt(paramBoolean ? 1 : 0);
                    binder.transact(2, data, reply, 0);
                    reply.readException();
                    limitAdTracking = 0 != reply.readInt();
                } finally {
                    reply.recycle();
                    data.recycle();
                }
                return limitAdTracking;
            }
        }
    }

MainActivity类调用

public class MainActivity extends AppCompatActivity { 
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            Executors.newSingleThreadExecutor().execute(new Runnable() {
                @Override
                public void run() {
                    try {
                        String adid = AdvertisingIdClient.getGoogleAdId(getApplicationContext());
                        Log.e("MainActivity", "adid: " + adid);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            });
        }
    }
