在 Android 应用程序中包含一个文件
Include a file in an Android application
我使用 android studio 创建了一个 java 应用程序。在该项目中,我创建了“assets”文件夹,并在其中放置了 json 文件,我将需要该文件来获取 GmailAPI 的凭据。
AssetFolder
我希望我可以访问 json 文件。我已经尝试过很多方法,但每次它都告诉我文件丢失了。
这是代码:
public class GmailApi {
public Gmail initService(String userId) throws GeneralSecurityException,
IOException {
JacksonFactory jsonFactory = JacksonFactory.getDefaultInstance();
final GoogleCredentials creds = ServiceAccountCredentials.fromStream(new FileInputStream("gmailapi-android.json"))
.createScoped(GmailScopes.GMAIL_SEND);
final GoogleCredentials delegatedCreds = creds.createDelegated("xxx@xxx.com");
HttpRequestInitializer requestInitializer = new HttpCredentialsAdapter(delegatedCreds);
HttpTransport transport = new NetHttpTransport.Builder().build();
// Construct the gmail object.
Gmail service = new Gmail.Builder(transport, jsonFactory, requestInitializer)
.setApplicationName("gmailapi")
.build();
return service;
}
}
有人能帮帮我吗?我应该在路径中放置什么才能访问 json 文件?
final GoogleCredentials creds = ServiceAccountCredentials.fromStream(new FileInputStream("gmailapi-android.json"))
你试过用这种方式打开文件吗?
AssetManager assetManager = getAssets();
InputStream ims = assetManager.open("gmailapi-android.json");
