I wanted to know how I can send and receive audio files via Google drive. I never used the Google Drive API, I’m starting now.

I did some research on the Internet, but I couldn’t do it. Some Researched and Indicated Examples:

https://github.com/googledrive/android-quickstart

https://stackoverflow.com/questions/13094781/google-drive-unresolved-imports

http://www.programcreek.com/java-api-examples/index.php?api=com.google.api.client.http.FileContent

https://stackoverflow.com/questions/12164024/android-open-and-save-files-to-from-google-drive-sdk/12321331#12321331

Basically I want to inform a Google Drive account, send and receive recordings by there. In case anyone can help me would be very grateful. Every hint is valid :)

Hug and thanks for your attention.

My progress:

Dependencies: Dependencias Permissions of the Manifesto: He reported in the example to import a permission called USE_CREDENTIALS, but it did not appear to me, so I am with only these two imported. . .

<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />

Code: The code is error in the following methods: Response.getEntity(), gFile.getDownloadURL(), get.setHeader(), getGFileName(gFile), client.execute(), am.getAuthToken(am.getAccounts()[0], ..., nul);

From what I saw, getGFileName(gFile) the tutorial tells me to do, but I don’t know if the others I have to do on hand too, or suddenly I imported or did something wrong..

In case someone can help me, the whole tip is valid. Hug!

  • Not from calls, but for example. Storing a recorded audio and sending to the drive (like when you send an audio message over watts).

    See this answer on Soen. It’s pretty detailed, gives you a "north".

  • Thanks for the tip, I’ll take a look here, whether you get it or not, warning soon :)

  • Very well explained, but I’m not able to get the sha1 of my app, I’m using Android Studio, in case you know how I can get this information please let me know.

  • 1

    I was able to generate sha1 by Command Prompt according to these instructions.. https://www.youtube.com/watch?v=ELEsytc5LyU I’ll keep trying here. Hug!

  • Hi guys, good, until then I managed to generate the SHA1. I imported all jar informed in the link. I also managed to register the app in Google Cloud Platform under "API >> Credentials Manager", with this I generated an API key to use in the java code of the app. However, after that, I could not follow for that example, I edited the content of the question showing my progress so far. The code still has some errors, I informed by comments the error lines. If someone can help me from this stage, all help is valid, I would be very grateful. Hug!
