GDrive-Rest-Android

This is the library for integrate Google Drive Rest into your Android app

Installation

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:1.4.3'
        // For Google login
        implementation 'com.google.android.gms:play-services-auth:17.0.0'
}

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

Usage

Initialization

	

 	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"));

Chain action

You can chain the command together. For Example, Search and delete first file that show in the result

mDriveServiceHelper.searchFile("filename.txt","text/plain")
                .continueWithTask(new Continuation<List<GoogleDriveFileHolder>, Task<Void>>() {
                    @Override
                    public Task<Void> then(@NonNull Task<List<GoogleDriveFileHolder>> task) throws Exception {
                        return mDriveServiceHelper.deleteFolderFile(task.getResult().get(0).getId());
                    }
                });
