Progress Bar (Android SDK)

The SDK interfaces—putObject, appendObject, uploadPart, uploadFile, and getObject—all support progress bar functionality. You can pass in a custom interface to listen for events related to upload progress and implement custom business logic.
Sample Code
The following code uses putObject as an example to demonstrate how to use the progress bar feature.
import android.os.Bundle;
import android.util.Log;
import androidx.appcompat.app.AppCompatActivity;
import com.volcengine.tos.TOSV2;
import com.volcengine.tos.TOSV2ClientBuilder;
import com.volcengine.tos.TosException;
import com.volcengine.tos.comm.event.DataTransferListener;
import com.volcengine.tos.comm.event.DataTransferStatus;
import com.volcengine.tos.comm.event.DataTransferType;
import com.volcengine.tos.model.object.ObjectMetaRequestOptions;
import com.volcengine.tos.model.object.PutObjectBasicInput;
import com.volcengine.tos.model.object.PutObjectInput;
import com.volcengine.tos.model.object.PutObjectOutput;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
public class PutObjectWithProgressExample extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
String endpoint = "your endpoint";
String region = "your region";
String accessKey = "your access key";
String secretKey = "your secret key";
String securityToken = "your security token";
String bucketName = "bucket-example";
String objectKey = "android-sdk-test-"+System.nanoTime();
String filePath = getFilesDir().getPath() + "/test.txt";
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_message);
TOSV2 tos = new TOSV2ClientBuilder().build(region, endpoint, accessKey, secretKey, securityToken);
Thread tosThread = new Thread(new Runnable() {
@Override
public void run() {
DataTransferListener listener = new DataTransferListener() {
@Override
public void dataTransferStatusChange(DataTransferStatus dataTransferStatus) {
if (dataTransferStatus.getType() == DataTransferType.DATA_TRANSFER_STARTED) {
Log.i("putObject", "data transfer started.");
} else if (dataTransferStatus.getType() == DataTransferType.DATA_TRANSFER_RW) {
Log.i("putObject", "data transfer, sends " + dataTransferStatus.getRwOnceBytes() +
" bytes once, has sent " + dataTransferStatus.getConsumedBytes() +
" bytes, total bytes: " + dataTransferStatus.getTotalBytes());
} else if (dataTransferStatus.getType() == DataTransferType.DATA_TRANSFER_FAILED) {
Log.i("putObject", "data transfer failed, has sent bytes: " + dataTransferStatus.getConsumedBytes() +
" , total bytes: " + dataTransferStatus.getTotalBytes());
} else if (dataTransferStatus.getType() == DataTransferType.DATA_TRANSFER_SUCCEED) {
Log.i("putObject", "data transfer finishes, has sent bytes: " + dataTransferStatus.getConsumedBytes() +

}
}
};
try(FileInputStream inputStream = new FileInputStream(filePath)){
ObjectMetaRequestOptions options = new ObjectMetaRequestOptions().setContentLength(new File(filePath).length());
PutObjectBasicInput basicInput = new PutObjectBasicInput().setBucket(bucketName).setKey(objectKey)
.setOptions(options).setDataTransferListener(listener);
PutObjectInput putObjectInput = new PutObjectInput().setPutObjectBasicInput(basicInput).setContent(inputStream);
PutObjectOutput output = tos.putObject(putObjectInput);
Log.i("putObject", "putObject succeed, object's etag is " + output.getEtag());
Log.i("putObject", "putObject succeed, object's crc64 is " + output.getHashCrc64ecma());
} catch (TosException e) {
Log.e("TosException", "putObject failed");
e.printStackTrace();
} catch (IOException e) {
Log.e("IOException", "putObject read file failed");
e.printStackTrace();
}
}
});
tosThread.start();
}
}
The following code uses getObject as an example to demonstrate how to use the progress bar feature.

}
} catch (TosException e) {
if (e.getStatusCode() == 404) {
Log.e("TosException", "the object you want to download is not found");
} else {
Log.e("TosException", "getObject failed");
}
e.printStackTrace();
}
}
});
tosThread.start();
