android - 共享前必须调用 Urban Airship 起飞(仅限 kit kat)

Question

我正在尝试学习如何使用 Urban Airship 发送推送通知，为此，我创建了一个使用它的非常简单的虚拟应用。

该应用有一个自定义自动驾驶仪和一个自定义通知工厂，以便测试某些功能。在 api 版本 >19 的 android 上一切正常。

但是，对于版本 19(我需要支持的最低版本)的设备，自动驾驶仪从未初始化，因此，每当我尝试访问 UAutopilot.shared()... 时，应用程序就会崩溃错误

takeoff must be called before shared

即使调用 Autopilot.autoTakeoff(application) 也无法解决问题。

主要 Activity :

public class MainActivity extends AppCompatActivity{

    TextView mTextView;
    Button mButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTextView = (TextView) findViewById(R.id.text);
        mButton = (Button)findViewById(R.id.button2);
        mButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mTextView.setText(UAirship.shared().getPushManager().getChannelId());
            }
        });
    }
}

自定义自动驾驶仪:

class CustomAutopilot extends Autopilot {

@Override
public void onAirshipReady(UAirship airship) {
    Logger.info("onAirshipReady");
    airship.getPushManager().setUserNotificationsEnabled(true);
    airship.getPushManager().setNotificationFactory(new CustomNotificationFactory(UAirship.getApplicationContext()));
}

@Nullable
@Override
public AirshipConfigOptions createAirshipConfigOptions(@NonNull Context context) {
    Logger.info("setting airship config options");
    AirshipConfigOptions options = new AirshipConfigOptions.Builder()
            .setDevelopmentAppKey("xxxxxxxxxxx")
            .setDevelopmentAppSecret("xxxxxxxxxxx")
            .setDevelopmentLogLevel(Log.DEBUG)

            .setInProduction(false)

            .setGcmSender("232973289571")

            .setNotificationIcon(R.drawable.icon)
            .setNotificationAccentColor(Color.rgb(0, 72, 51))
            .build();
        return options;
    }
}

自定义通知工厂:

public class CustomNotificationFactory extends NotificationFactory {
    public CustomNotificationFactory(@NonNull Context context) {
        super(context);
    }

    @Nullable
    @Override
    public Notification createNotification(@NonNull PushMessage message, int notificationId) {
        NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(getContext())
                .setContentTitle("altered " + message.getTitle())
                .setContentText(message.getAlert())
                .setSmallIcon(message.getIcon(getContext(), R.drawable.icon))
                .setColor(Color.rgb(212, 45, 198))
                .setVibrate(new long[]{100, 50, 100, 200, 100, 50, 100})
                .setPriority(Notification.PRIORITY_MAX);

        return builder.build();

    }
}

您是否在 list 中注册自动驾驶仪？

在应用入口中:

    <!-- Autopilot calls takeOff without the need to override the Application -->
    <meta-data
        android:name="com.urbanairship.autopilot"
        android:value="your.package.here.CustomAutopilot"/>
