1）、 注：鹰眼 Android SDK v3.0以上版本支持随轨迹上传图像等对象数据，若需使用此功能，该参数需设为 true，且需导入bos-android-sdk-1.0.2.jar。
// 是否需要对象存储服务，默认为：false，关闭对象存储服务。
boolean isNeedObjectStorage = true;
// 初始化轨迹服务
Trace mTrace = new Trace(serviceId, entityName, isNeedObjectStorage);
// 是否需要对象存储服务，默认为：false，关闭对象存储服务。
boolean isNeedObjectStorage = true;
// 初始化轨迹服务
Trace mTrace = new Trace(serviceId, entityName, isNeedObjectStorage);
核心代码
1.开启对象储存服务
JAVA
// 是否需要对象存储服务，默认为：false，关闭对象存储服务。
boolean isNeedObjectStorage = true;
// 初始化轨迹服务
Trace mTrace = new Trace(serviceId, entityName, isNeedObjectStorage);
mClient.startTrace(mTrace, traceListener);

2.上传图片
JAVA
/**
* 上传图片
* @param path
*/
private void putObject(String path) {
// 对象key（即文件名称包括后缀，如track.jpg、track.png）
String[] paths = path.split("/");
objectKey = paths[paths.length - 1];
// 对象类型
BosObjectType objectType = BosObjectType.image;
try {
// 通过文件形式上传
File file = new File(path);
BosPutObjectRequest request = BosPutObjectRequest.buildFileRequest(trackApp.getTag(), trackApp.serviceId,
objectKey, objectType, file);
if (trackApp.isTraceStarted) {
trackApp.mClient.putObject(request, bosListener);
} else {
viewUtil.showToast(this, "请在轨迹追踪页面开启对象存储并开启鹰眼服务");
}
} catch (Exception e) {
e.printStackTrace();
}
}

3.获取图片
JAVA
/**
* 获取对象（图片）
*
* @param view
*/
public void onGetObject(View view) {
// 对象类型
BosObjectType objectType = BosObjectType.image;
BosGetObjectRequest request = new BosGetObjectRequest(trackApp.getTag(), trackApp.serviceId, objectKey,
objectType);
trackApp.mClient.getObject(request, bosListener);
}

4.获取图片URL
JAVA
/**
* 获取对象（图片）URL
*
* @param view
*/
public void onGeneratePresignedUrl(View view) {
// 对象类型
BosObjectType objectType = BosObjectType.image;
BosGeneratePresignedUrlRequest request = new BosGeneratePresignedUrlRequest(trackApp.getTag(),
trackApp.serviceId, objectKey, objectType);
// 图片处理命令
ImageProcessCommand imageProcessCommand = new ImageProcessCommand();
imageProcessCommand.setAngle(180);
request.setImageProcessCommand(imageProcessCommand);
// 文字水印命令
TextWatermarkCommand textWatermarkCommand = new TextWatermarkCommand();
textWatermarkCommand.setText("百度鹰眼");
textWatermarkCommand.setFontFamily(FontFamily.KaiTi);
textWatermarkCommand.setAngle(45);
textWatermarkCommand.setFontColor("0000FF");
request.setTextWatermarkCommand(textWatermarkCommand);
trackApp.mClient.generatePresignedUrl(request, bosListener);
}

5.监听状态
JAVA
bosListener = new OnBosListener() {
@Override
public void onPutObjectCallback(BosPutObjectResponse response) {
viewUtil.showToast(BosActivity.this, response.getMessage());
}
@Override
public void onGetObjectCallback(final BosGetObjectResponse response) {
if (response.getStatus()!= StatusCodes.SUCCESS) {
viewUtil.showToast(BosActivity.this, response.getMessage());
return;
}
viewUtil.showToast(BosActivity.this, getString(R.string.save_picture));
new Thread() {
@Override
public void run() {
saveObject(response);
}
}.start();
}
@Override
public void onGeneratePresignedUrlCallback(BosGeneratePresignedUrlResponse response) {
if (response.getStatus()!= StatusCodes.SUCCESS) {
viewUtil.showToast(BosActivity.this, response.getMessage());
return;
}
// 获取Object的URL
Uri uri = Uri.parse(response.getUrl());
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// 执行URL
BosActivity.this.startActivity(intent);
}
};
