连接Google Drive时触发IllegalArgumentException异常的排查求助

Looking at your stack trace, the critical error is java.lang.IllegalArgumentException: the name must not be empty: null — this pops up when GoogleAuthUtil tries to fetch an auth token but can't validate the account you're using. Let's break down all the issues in your code and fix them:

1. Camera flow is broken (and asynchronous logic is wrong) #

Your handleCamera() method only creates a camera Intent but never launches the camera! Even worse, you call save2Drive() immediately in onCreate() — the photo hasn't been taken yet (or even started), which would cause file-related errors later.

Fix the camera launch: #

public void handleCamera(){
    String mediaStorageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getPath();
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US).format(new Date());
    fileUri = Uri.fromFile(new java.io.File(mediaStorageDir + java.io.File.separator + "IMG_" + timeStamp + ".jpg"));
    
    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
    // Actually start the camera and wait for results
    startActivityForResult(cameraIntent, CAPTURE_IMAGE); 
}

Then add an onActivityResult method to trigger upload only after the photo is taken:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAPTURE_IMAGE && resultCode == RESULT_OK) {
        // Photo was taken successfully — now upload it
        save2Drive();
    } else {
        showToast("Photo capture failed or was canceled");
    }
}

2. Hardcoded account is causing auth failure #

The "name must not be empty" error means the system doesn't recognize the hardcoded blogmsr28@gmail.com account. Here's why and how to fix it:

• Ensure the account exists on your device: Your Android device must have blogmsr28@gmail.com added as a Google account in Settings > Accounts. If it's not there, the system can't authenticate it.
• Stop hardcoding accounts (recommended): Hardcoding is inflexible and error-prone. Use the account picker to let users select their own account:

// Replace your onCreate account setup with this
credential = GoogleAccountCredential.usingOAuth2(this, Arrays.asList(new String[]{DriveScopes.DRIVE}));
// Launch account picker
Intent accountPickerIntent = credential.newChooseAccountIntent();
startActivityForResult(accountPickerIntent, REQUEST_ACCOUNT_PICKER); // Define REQUEST_ACCOUNT_PICKER as 1001

Update onActivityResult to handle the account selection:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode) {
        case REQUEST_ACCOUNT_PICKER:
            if (resultCode == RESULT_OK && data != null) {
                String selectedAccount = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
                if (selectedAccount != null) {
                    credential.setSelectedAccountName(selectedAccount);
                    service = getDriveService(credential);
                    // Now start the camera
                    handleCamera();
                }
            }
            break;
        case CAPTURE_IMAGE:
            // Handle photo result as before
            break;
    }
}

3. Fix Google Play Services resource warning #

The The Google Play services resources were not found message means your project isn't properly set up with Google Play Services. Fix this:

• Add these dependencies to your module-level build.gradle:

implementation 'com.google.android.gms:play-services-auth:20.7.0'
implementation 'com.google.apis:google-api-services-drive:v3-rev20240422-2.0.0'
implementation 'com.google.api-client:google-api-client-android:2.0.0'

• Add these to your AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <!-- For older Android versions -->

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

4. Handle authorization exceptions properly #

Your save2Drive() method catches UserRecoverableAuthIOException but does nothing — this exception requires launching an intent to let users grant permissions. Fix it:

catch (UserRecoverableAuthIOException e) {
    // Launch the authorization intent
    startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION); // Define REQUEST_AUTHORIZATION as 1002
}
