[英]Google Drive image upload from android
我正在嘗試使用API將圖像上傳到Google驅動器。 我已經搜索了很多東西,但沒有找到方法。 我有一個演示代碼,可以上傳文本文件,並且可以正常工作。 我需要更改它以上傳圖像。 這是代碼...
public void CreateFileOnGoogleDrive(DriveContentsResult result){
final DriveContents driveContents = result.getDriveContents();
// Perform I/O off the UI thread.
new Thread() {
@Override
public void run() {
// write content to DriveContents
OutputStream outputStream = driveContents.getOutputStream();
Writer writer = new OutputStreamWriter(outputStream);
try {
writer.write("Hello abhay!");
writer.close();
} catch (IOException e) {
Log.e(TAG, e.getMessage());
}
MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
.setTitle("abhaytest2")
.setMimeType("text/plain")
.setStarred(true).build();
// create a file in root folder
Drive.DriveApi.getRootFolder(mGoogleApiClient)
.createFile(mGoogleApiClient, changeSet, driveContents)
.setResultCallback(fileCallback);
}
}.start();
}
我如何更改此代碼以從文件上傳圖像。(通過設備中圖像的給定位置)? 我發現很少有教程,但這些教程已被棄用。
首先,您無需創建文件,然后將內容寫入其中。
private void saveFiletoDrive(final File file, final String mime) {
Drive.DriveApi.newDriveContents(mDriveClient).setResultCallback(
new ResultCallback<DriveContentsResult>() {
@Override
public void onResult(DriveContentsResult result) {
if (!result.getStatus().isSuccess()) {
Log.i(TAG, "Failed to create new contents.");
return;
}
Log.i(TAG, "Connection successful, creating new contents...");
OutputStream outputStream = result.getDriveContents()
.getOutputStream();
FileInputStream fis;
try {
fis = new FileInputStream(file.getPath());
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] buf = new byte[1024];
int n;
while (-1 != (n = fis.read(buf)))
baos.write(buf, 0, n);
byte[] photoBytes = baos.toByteArray();
outputStream.write(photoBytes);
outputStream.close();
outputStream = null;
fis.close();
fis = null;
} catch (FileNotFoundException e) {
Log.w(TAG, "FileNotFoundException: " + e.getMessage());
} catch (IOException e1) {
Log.w(TAG, "Unable to write file contents." + e1.getMessage());
}
String title = file.getName();
MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder()
.setMimeType(mime).setTitle(title).build();
if (mime.equals(MIME_PHOTO)) {
if (VERBOSE)
Log.i(TAG, "Creating new photo on Drive (" + title
+ ")");
Drive.DriveApi.getFolder(mDriveClient,
mPicFolderDriveId).createFile(mDriveClient,
metadataChangeSet,
result.getDriveContents());
} else if (mime.equals(MIME_VIDEO)) {
Log.i(TAG, "Creating new video on Drive (" + title
+ ")");
Drive.DriveApi.getFolder(mDriveClient,
mVidFolderDriveId).createFile(mDriveClient,
metadataChangeSet,
result.getDriveContents());
}
if (file.delete()) {
if (VERBOSE)
Log.d(TAG, "Deleted " + file.getName() + " from sdcard");
} else {
Log.w(TAG, "Failed to delete " + file.getName() + " from sdcard");
}
}
});
}
使用此代碼將圖片上傳到Google驅動器...
new Thread() {
@Override
public void run() {
// write content to DriveContents
OutputStream outputStream = driveContents.getOutputStream();
// Write the bitmap data from it.
MetadataChangeSet metadataChangeSet = new MetadataChangeSet.Builder()
.setMimeType("image/jpeg").setTitle(title)
.build();
Bitmap image = BitmapFactory.decodeFile(location));
ByteArrayOutputStream bitmapStream = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.JPEG, 80, bitmapStream);
try {
outputStream.write(bitmapStream.toByteArray());
} catch (IOException e1) {
Log.i("E", "Unable to write file contents.");
}
image.recycle();
outputStream = null;
String title = "noisy";
Log.i("E", "Creating new pic on Drive (" + title + ")");
Drive.DriveApi.getFolder(mGoogleApiClient,driveId)
.createFile(mGoogleApiClient, metadataChangeSet, driveContents)
.setResultCallback(fileCallback);
}
}.start();
