一个简单的Android实例是通过阿里云的Android SDK实现文件上传功能。以下是一个简单的示例代码:
1.首先,确保已在Android项目的build.gradle文件中添加阿里云的Maven仓库地址:
repositories {
maven {
url "http://maven.aliyun.com/nexus/content/repositories/releases/"
}
}
2.然后在项目的build.gradle文件中添加阿里云的SDK依赖:
dependencies {
implementation 'com.aliyun.dpa:aliyun-android-sdk-core:4.5.3'
implementation 'com.aliyun.dpa:aliyun-android-sdk-oss:2.11.0'
}
3.在你的Activity或Fragment中使用以下代码创建阿里云OSSClient实例并上传文件:
import android.content.Context;
import android.os.AsyncTask;
import android.util.Log;
import com.alibaba.sdk.android.oss.ClientConfiguration;
import com.alibaba.sdk.android.oss.OSS;
import com.alibaba.sdk.android.oss.OSSClient;
import com.alibaba.sdk.android.oss.common.OSSLog;
import com.alibaba.sdk.android.oss.common.auth.OSSCredentialProvider;
import com.alibaba.sdk.android.oss.common.auth.QueryStringSigner;
import com.alibaba.sdk.android.oss.common.auth.OSSPlainTextAKSKCredentialProvider;
import com.alibaba.sdk.android.oss.model.PutObjectRequest;
import com.alibaba.sdk.android.oss.model.PutObjectResult;
import java.io.IOException;
public class OSSUploader {
private static final String TAG = OSSUploader.class.getSimpleName();
private static final String ENDPOINT = "http://your_oss_endpoint.com";
private static final String ACCESS_KEY_ID = "your_access_key_id";
private static final String ACCESS_KEY_SECRET = "your_access_key_secret";
private static final String BUCKET_NAME = "your_bucket_name";
private OSS oss;
public OSSUploader(Context context) {
// 初始化OSSClient
OSSCredentialProvider credentialProvider = new OSSPlainTextAKSKCredentialProvider(ACCESS_KEY_ID, ACCESS_KEY_SECRET);
ClientConfiguration conf = new ClientConfiguration();
conf.setConnectionTimeout(15 * 1000);
conf.setSocketTimeout(15 * 1000);
conf.setIsSecurityTunnelRequired(false);
conf.setMaxConcurrentRequest(5);
conf.setMaxErrorRetry(2);
oss = new OSSClient(context, ENDPOINT, credentialProvider, conf);
}
public void uploadFile(String objectKey, String localFilePath) {
// 构造上传请求
PutObjectRequest put = new PutObjectRequest(BUCKET_NAME, objectKey, localFilePath);
// 异步上传
new AsyncTask<PutObjectRequest, Void, PutObjectResult>() {
@Override
protected PutObjectResult doInBackground(PutObjectRequest... params) {
try {
return oss.putObject(params[0]);
} catch (Exception e) {
Log.e(TAG, "Upload failed: " + e.getMessage());
return null;
}
}
@Override
protected void onPostExecute(PutObjectResult result) {
if (result != null) {
Log.d(TAG, "Upload succeed.");
} else {
Log.e(TAG, "Upload failed.");
}
}
}.execute(put);
}
}
使用时,可以在onCreate()
方法或其他适当的地方创建OSSUploader
实例并调用uploadFile()
方法:
OSSUploader uploader = new OSSUploader(this);
uploader.uploadFile("object_key", "local_file_path");
注意替换ENDPOINT
、ACCESS_KEY_ID
、ACCESS_KEY_SECRET
和BUCKET_NAME
为你自己的配置。
以上示例仅演示了文件上传功能,更多关于Aliyun OSS的功能和操作请参考阿里云官方文档。
下面是一个简单的Android实例,演示了如何使用阿里云的移动推送服务。请确保已在项目中集成了阿里云移动推送的SDK,并在阿里云控制台中创建了应用并获得了APP_KEY和APP_SECRET。
- 在AndroidManifest.xml文件中添加以下权限和服务声明:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<application>
...
<service android:name="com.alibaba.sdk.android.push.GPushService">
<intent-filter>
<action android:name="com.alibaba.sdk.android.push.RECEIVE_MESSAGE" />
</intent-filter>
</service>
</application>
- 在你的Activity中初始化阿里云移动推送SDK,并设置注册、绑定和解绑的回调:
import com.alibaba.sdk.android.push.CloudPushService;
import com.alibaba.sdk.android.push.CommonCallback;
import com.alibaba.sdk.android.push.notification.BasicCustomPushNotification;
import com.alibaba.sdk.android.push.notification.CustomPushNotification;
import com.alibaba.sdk.android.push.notification.CustomNotificationBuilder;
public class MainActivity extends AppCompatActivity {
private CloudPushService cloudPushService;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 初始化阿里云移动推送SDK
cloudPushService = PushServiceFactory.getCloudPushService();
cloudPushService.register(this, new CommonCallback() {
@Override
public void onSuccess(String response) {
// 注册成功回调
Log.d(TAG, "register success");
}
@Override
public void onFailed(String errorCode, String errorMessage) {
// 注册失败回调
Log.e(TAG, "register failed: " + errorCode + " - " + errorMessage);
}
});
// 设置消息点击后的行为
cloudPushService.setPushNotificationBuilder(new CustomNotificationBuilder() {
@Override
public BaseNotification getNotification(Context context, CustomPushNotification customPushNotification) {
BasicCustomPushNotification notification = new BasicCustomPushNotification(context, customPushNotification);
notification.setTitle("My App");
notification.setTickerText("You have a new message");
notification.setContentTitle("My App");
notification.setContentText(customPushNotification.getBody());
return notification;
}
});
}
// 绑定阿里云移动推送
private void bindPush() {
cloudPushService.bindAccount("your_alias", new CommonCallback() {
@Override
public void onSuccess(String response) {
// 绑定成功回调
Log.d(TAG, "bind push success");
}
@Override
public void onFailed(String errorCode, String errorMessage) {
// 绑定失败回调
Log.e(TAG, "bind push failed: " + errorCode + " - " + errorMessage);
}
});
}
// 解绑阿里云移动推送
private void unbindPush() {
cloudPushService.unbindAccount(new CommonCallback() {
@Override
public void onSuccess(String response) {
// 解绑成功回调
Log.d(TAG, "unbind push success");
}
@Override
public void onFailed(String errorCode, String errorMessage) {
// 解绑失败回调
Log.e(TAG, "unbind push failed: " + errorCode + " - " + errorMessage);
}
});
}
}
- 调用
bindPush()
方法,在登录成功后绑定阿里云移动推送;调用unbindPush()
方法,在退出登录时解绑阿里云移动推送。
这只是一个简单的示例,更详细的API使用方法和相关功能,请参考阿里云移动推送的官方文档。
