我正在尝试通过蜂窝网络强制网络请求。为此,我要求来自 ConnectivityManager 的移动网络回调,如下所示:

private static final String LOG_TAG = "Main";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final ConnectivityManager cm = (ConnectivityManager) getSystemService(
            Context.CONNECTIVITY_SERVICE);
    // Request the mobile network. This doesn't turn on the mobile network, it just gives the app a handle to it.
    NetworkRequest.Builder req = new NetworkRequest.Builder();
    req.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);
    req.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);
    cm.requestNetwork(req.build(), new MobileNetworkCallback(cm), 60_000);
}

/**
 * Listens for the requested network on API 21+. When the network is available, the network request is done.
 */
private static class MobileNetworkCallback extends ConnectivityManager.NetworkCallback {
    ConnectivityManager connectivityManager;

    private MobileNetworkCallback(ConnectivityManager connectivityManager) {
        this.connectivityManager = connectivityManager;
    }

    @Override
    public void onAvailable(Network network) {
        Log.v(LOG_TAG, "got mobile network");
        connectivityManager.unregisterNetworkCallback(this);
    }

    @Override
    public void onUnavailable() {
        Log.v(LOG_TAG, "network unavailable");
        connectivityManager.unregisterNetworkCallback(this);
    }

}

通常有效,即使当前已连接 Wifi。但是,有时即使存在有效的移动连接,我也会收到“不可用”回调。

我记录了以下日志:
