android - 如何在应用程序关闭时获取 OneSignal 推送通知？

Question

我已经在我的应用程序中实现了 Onesignal 推送通知，但是当我的应用程序关闭时我没有收到推送通知。这是我的实现代码。

LoginActivity.java

public class LoginActivity extends BaseActivity {

    private static final int REQUEST_MARK_READ = 165;
    private ListView userListView;
    private static final String TAG = LoginActivity.class.getSimpleName();
    private static ArrayList<String> userids=new ArrayList<>();
    private static boolean activityStarted;

    public static void start(Context context) {
        Intent intent = new Intent(context, LoginActivity.class);
        context.startActivity(intent);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (activityStarted && getIntent() != null && (getIntent().getFlags() & Intent.FLAG_ACTIVITY_REORDER_TO_FRONT) != 0)
        {
            finish();
            return;
        }
        activityStarted = true;
        setContentView(R.layout.activity_login);
        if (SharedPreferencesUtil.hasQbUser()) {
            try {
                Onesignal();
                recreateChatSession();
            } catch (Exception e) {
                e.printStackTrace();
            }
            return;
        }
        Onesignal();

        userListView = _findViewById(R.id.list_login_users);
        TextView listHeader = (TextView) LayoutInflater.from(this)
                .inflate(R.layout.include_list_hint_header, userListView, false);
        listHeader.setText(R.string.login_select_user_for_login);

        userListView.addHeaderView(listHeader, null, false);
        userListView.setOnItemClickListener(new OnUserLoginItemClickListener());
        buildUsersList();
    }

注意-请忽略 java 文件中不必要的方法调用。我刚刚展示了与 OneSignal 推送通知相关的代码。为什么我的应用关闭时没有收到通知？

Answer 1

如果您通过将应用程序置于“强制停止”状态来关闭您的应用程序，则不会收到大多数事件，包括用于推送通知的 GCM/FCM 消息。可以通过以下方式将应用置于此状态。

• 在“设置”>“应用”中，按下“强制停止”。
• 在某些设备上长按后退按钮。
• 使用第 3 方任务 killer ，如 Greenify。
• 应用程序在某些华为、小米或索尼设备上因自定义 Android 调整而关闭。可以更改以下设备设置以防止出现这种情况。
  • 华为 - 转到“设置”>“ protected 应用”，检查您的应用。
  • 小米 - 确保在设置中为您的应用启用“自动启动”属性。
  • Sony - 点击电池图标。转到电源管理 > STAMINA 模式 > 处于待机状态的应用程序 > 添加您的应用程序。

要确认您的应用状态是否存在问题，请发送一些通知并检查以下 GCM logcat 条目。

W/GCM-DMM: broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE pkg=com.onesignal.example (has extras) }

一些设备制造商会将应用列入白名单，以免进入强制关闭状态。例如 Gmail 和 Whatsapp。
