我正在尝试将 AdMob ID 从 JsonData 获取到我的应用中，以便将来可以更改它。

我的愿景:

JSON 文件将上传到我的服务器，其链接将位于应用程序内部。在 json 文件中找到的 AdMob ID 应在应用程序 adUnitID 中使用。到目前为止，我已经做到了:

String jsonToProcess = "https://drive.google.com/uc?id=113RUepiYecy5pBwj-t4BtBXwlQwgf-dU";
String interstialAd = new JsonParser().parse(jsonToProcess).getAsJsonObject()
    .get("response").getAsJsonObject()
    .get("Interstial AD").getAsString();

mInterstitialAd = new InterstitialAd(getActivity());
mInterstitialAd.setAdUnitId(interstialAd);
mInterstitialAd.loadAd(new AdRequest.Builder().build());
mInterstitialAd.setAdListener(new AdListener() {
    @Override
    public void onAdClosed() {
        // Load the next interstitial.
        Toast.makeText(getActivity(), "Thank you for supporting us, kind mate :)",
        Toast.LENGTH_LONG).show();
        mInterstitialAd.loadAd(new AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build());
    }
});

这是我的 json 文件:

{
    "response": {
            "Interstial AD": "ca-app-pub-3940256099942544/1033173712"
        }
}

问题是，它不仅不起作用，而且还导致我的应用程序崩溃并出现以下错误:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.domian.app/com.domain.app.MainActivity}: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 7 path $

最佳答案

您需要先从服务器读取该文件，然后解析结果...它可以像这个方法一样简单:

public String readFileFromServer(String fileUrl) {

    String fileContent;
    try {
        URL url = new URL(fileUrl);
        return new Scanner(url.openStream()).useDelimiter("\\A").next();
    } catch (IOException e) {
        throw new RuntimeException("Error while trying to read file from server!", e);
    }
}

获取文件内容后，将其传递给parse()方法即可。
