获取Google Advertising ID作为唯一识别码

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();
                }
            }
        });
    }
}
