我正在尝试从JsonData获取AdMob ID到我的应用程序中，以便将来可以更改它。
我的视野：
JSON文件将被上传到我的服务器中，并且其链接将位于应用程序内部。在json文件中找到的AdMob ID应该在应用程序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，不仅它不起作用，而且由于以下错误使我的应用程序崩溃：
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 $

您需要先从服务器读取该文件，然后解析结果...它可以像这种方法一样简单：
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，只需将其传递给parse()方法即可。

您提供了解析方法的网址，而不是有效的NULL。默认情况下，每个JSON参数都被视为String。在您的情况下，您需要下载内容然后进行解析。例如：
字符串非页内广告；
JSON另请参阅：
