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();
                }
            }
        });
    }
}
