This is the library for integrate Google Drive Rest into your Android app
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
// Google Drive Rest library
implementation 'com.github.ammarptn:GDrive-Rest-Android:1.4.2'
// For Google login
implementation 'com.google.android.gms:play-services-auth:16.0.1'
}
Step 3. Add OAuth 2.0 client IDs at Google API console
Step 4. Enable Google Drive API in Google API console
Step 5. Add "../auth/drive" in Scopes for Google APIs
Optional Step 6. Add "../auth/drive.appdata" in Scopes if you want to access application data folder
GoogleSignInAccount account = GoogleSignIn.getLastSignedInAccount(getApplicationContext());
...
//if you want to use your common space of G drive
mDriveServiceHelper = new DriveServiceHelper(getGoogleDriveService(getApplicationContext(), account, "your_app_name_here"));
//if you want to use your appData space of G drive
mDriveServiceHelper = new AppDataDriveServiceHelper(getGoogleAppDataDriveService(getApplicationContext(), account, "your_app_name_here"));
