i'm working on more futures...
- Step 1. Add the JitPack repository to your project gradle file
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}- Step 2. Add the implementation dependency to your app gradle file
dependencies {
...
implementation 'com.github.yorondahacker:AndroidBackBlazeHelper:{version}'
...
}- Step 3. Gradle sync and you're ready to go!
Create a blaze client object and add your applicationKeyId , applicationKey.
BlazeClient client = new BlazeClient(this,applicationKeyId //TODO replace applicationKeyId with your key
,applicationKey); //TODO replace applicationKey with your keyTo upload files create an object of BlazeFileUploader and pass the BlazeClinet object and your bucketId.
BlazeFileUploader blazeFileUploader =
new BlazeFileUploader( client , bucketId); //TODO replace bucketId with your Bucket IdNow to start uploading the files use this method and add your file uri and the file name.
blazeFileUploader.startUploading(fileUri, fileName);To change it's type use this line
blazeFileUploader.startUploading(fileUri, fileName , contentType); // replace the content type with mime type or choose one from FileTypes.class e.g. FileTypes.IMAGE_TYPETo upload multiple files please use the model MultiFile.class here is how..
ArrayList<MultiFile> arrayList = new ArrayList<>();
MultiFile multiFile = new MultiFile();
for(int i = 0; i < count; i++){
Uri fileUri = data.getClipData().getItemAt(i).getUri();
multiFile.init(fileUri, new File(fileUri.getPath()).getAbsolutePath() , FileTypes.IMAGE_TYPE);
arrayList.add(multiFile);
}
//use this method...
blazeFileUploader.startUploadingMultipleFiles(arrayList);To listen to changes while uploading use this method.
blazeFileUploader.setOnUploadingListener(new UploadListener() {
@Override
public void onUploadStarted() {
Log.v(TAG , "uploading started");
}
@Override
public void onUploadProgress(int percentage, long progress, long total) {
Log.v(TAG , "uploading on progress %"+percentage);
}
@Override
public void onUploadFinished(String response , boolean allFilesUploaded) {
Log.v(TAG , "uploading finised " +response);
}
@Override
public void onUploadFailed(Exception e) {
//Handle Errors
}
});To download files create an object of BlazeFileDownloader and pass the BlazeClient that you created before.
BlazeFileDownloader blazeFileDownloader = new BlazeFileDownloader(client);Now start downloading using this method.
blazeFileDownloader.startDownloading(bucketName, fileName); //TODO replace bucketName with your bucket name and fileName with your file nameTo download multiple files use the model MultiDownload
ArrayList<MultiDownload> arrayList = new ArrayList<>();
arrayList.add(new MultiDownload("Beavis-1.png"));
blazeFileDownloader.startDownloadingMultipleFiles(bucketName, arrayList);if your file name has no file extension call this method before you start uploading:
blazeFileDownloader.setFileExtension(".jpg");To listen to the downloading progress.
blazeFileDownloader.setDownloadListener(new DownloadListener() {
@Override
public void onDownloadStart() {
}
@Override
public void onDownloadProgress(int percentage, long progress, long total) {
}
@Override
public void onDownloadFinish(boolean allFilesDownloaded) {
}
@Override
public void onUploadFailed(Exception e) {
}
});
