七牛---Android SDK常见问题总结

很多用户在使用七牛中遇到各种Android SDK的问题，这里总结一些常见的问题:

1).遇到运行报错NoClassDefFound,这个其实是有些jar包没有正常导入，可以参考官网上面的需要的jar包依赖，另外也可以直接下载如下总结的依赖的jar包：

jar包依赖关系如下：
1.qiniu-android-sdk-7.2.0依赖okhttp3.0以上，依赖包如下:
http://7xsjg3.com1.z0.glb.clouddn.com/qiniu-android-sdk-7.2.0.jar
http://7xsjg3.com1.z0.glb.clouddn.com/okhttp-3.2.0.jar
http://7xsjg3.com1.z0.glb.clouddn.com/okio-1.6.0.jar
http://7xsjg3.com1.z0.glb.clouddn.com/happy-dns-0.2.3.2.jar

2.qiniu-android-sdk-7.1.0-7.1.2可以直接使用okhttp(2.6.0以上okhttp3.0以下)，依赖包如下：
http://7xkn2v.dl1.z0.glb.clouddn.com/qiniu-android-sdk-7.1.0.jar
http://7xkn2v.dl1.z0.glb.clouddn.com/okhttp-2.7.0.jar
http://7xkn2v.dl1.z0.glb.clouddn.com/happy-dns-0.2.3.2.jar
http://7xkn2v.dl1.z0.glb.clouddn.com/okio-1.6.0.jar

3.qiniu-android-sdk-7.0.9 必须和 android-async-http-1.4.9 依赖，而 android-async-http-1.4.9 又必须依赖cz.msebera.android(即下载httpclient-4.4.1.1.jar)，所以使用最新的 7.0.9Android 依赖的是 android-async-http-1.4.9.jar 和httpclient-4.4.1.1.jar 和 happy-dns.jar
http://7xl4c6.com2.z0.glb.qiniucdn.com/qiniu-android-sdk-7.0.9.jar
http://7xl4c6.com2.z0.glb.qiniucdn.com/android-async-http-1.4.9.jar
http://7xl4c6.com2.z0.glb.qiniucdn.com/httpclient-4.4.1.1.jar
http://7xl4c6.com2.z0.glb.qiniucdn.com/happy-dns-0.2.3.2.jar

4.qiniu-android-sdk-7.0.7~7.0.8 依赖的是 android-async-http-1.4.6~1.4.8，而 android-async-http-1.4.6~1.4.8 不需要依赖cz.msebera.android所以使用 qiniu-android-sdk-7.0.7~7.0.8 只需要导入 android-async-http-1.4.6~1.4.8 和 happy-dns.jar
http://7xl4c6.com2.z0.glb.qiniucdn.com/qiniu-android-sdk-7.0.7.2.jar
http://7xl4c6.com2.z0.glb.qiniucdn.com/android-async-http-1.4.8.jar
http://7xl4c6.com2.z0.glb.qiniucdn.com/happy-dns-0.2.3.2.jar

2).有关Android Studio以及Eclipse安装运行Android Demo步骤，这里以Android Studio为实例:

1.将以上相应的jar包也拷贝到工程的 libs 目录下，集成后的工程示例如下：

2.修改 build.gradle
双击打开您的工程目录下的 build.gradle，确保已经添加了对 相关jar包的依赖，如下所示：

dependencies {
     compile files('libs/happy-dns-0.2.3.2.jar')
    compile files('libs/okio-1.6.0.jar')
    compile files('libs/okhttp-2.7.0.jar')
    compile files('libs/qiniu-android-sdk-7.1.2.jar')
}

3.添加相关权限，在 app/src/main 目录中的 AndroidManifest.xml 中增加如下 uses-permission 声明

 <uses-permission android:name="android.permission.INTERNET"/>
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

4.布局，在res/layout/activity_main.xml添加相应的上传的按钮以及相关控件，以下以一个简单的布局为例:

"wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:textSize="20sp"
        android:layout_marginTop="10dp"
        android:text="七牛云存储 SDK"
        android:id="@+id/textView"
        android:layout_alignParentTop="true"
        />

    "wrap_content"
        android:layout_height="wrap_content"
        android:text="上传"
        android:id="@+id/button"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"/>

效果如下:

5.逻辑代码, 为按钮添加上传事件，这里以上传一个byte数组为例，另外，上传的数据可以是文件路径或者文件，以下给出具体的代码:

package com.dxy.cloud.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.qiniu.android.http.ResponseInfo;
import com.qiniu.android.storage.UpCompletionHandler;
import com.qiniu.android.storage.UploadManager;
import com.qiniu.android.storage.UploadOptions;
import org.json.JSONObject;

public class MainActivity extends Activity implements View.OnClickListener {

    //指定upToken, 强烈建议从服务端提供get请求获取, 这里为了掩饰直接指定key
    public static String uptoken = "um6IEH7mtwnwkGpjImD08JdxlvViuELhI4mFfoeL:NCnWTr1D3jR_9_dxj6geIgPBQq4=:eyJzY29wZSI6ImFuZHJvaWRkZW1vIiwiZGVhZGxpbmUiOjIzMDk5MjE5MTIsInJldHVybkJvZHkiOiJ7IFwiaGFzaFwiOiQoZXRhZyksXCJrZXlcIjokKGtleSksXCJtaW1lVHlwZVwiOiQobWltZVR5cGUpLCBcImZzaXplXCI6JChmc2l6ZSl9In0=";
    private Button btnUpload;
    private TextView textView;
    private UploadManager uploadManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = (TextView) findViewById(R.id.textView);
        btnUpload = (Button) findViewById(R.id.button);
        btnUpload.setOnClickListener(this);
        //new一个uploadManager类
        uploadManager = new UploadManager();

    }

    @Override
    public void onClick(View v) {
        Log.i("qiniutest", "starting......");
        byte[] data=new byte[]{ 0, 1, 2, 3};
        //设置上传后文件的key
        String upkey = "uploadtest.txt";
        uploadManager.put(data, upkey, uptoken, new UpCompletionHandler() {
            public void complete(String key, ResponseInfo rinfo, JSONObject response) {
                btnUpload.setVisibility(View.INVISIBLE);
                String s = key + ", " + rinfo + ", " + response;
                Log.i("qiniutest", s);
                textView.setTextSize(10);
                String o = textView.getText() + "\r\n\r\n";
                //显示上传后文件的url
                textView.setText(o + s + "\n" + "http://xm540.com1.z0.glb.clouddn.com/" + key);
            }
        }, new UploadOptions(null, "test-type", true, null, null));

    }
}

运行的效果图如下:

3).有关断点续传，暂停上传，设置自定义变量的用法，这里以一个简单的Demo给出下实现的方法，这里的Demo主要实现从相册选择一张图片上传来说明。

可以参考放GitHub(Android Studio)上的源码: https://github.com/clouddxy/AndroidDemo
这里直接给出MainActivity中的代码:

    private TextView textview;
    private ProgressBar progressbar;
    public static final int RESULT_LOAD_IMAGE = 1;
    private volatile boolean isCancelled = false;
    UploadManager uploadManager;
    public MainActivity() {
        //断点上传
        String dirPath = "/storage/emulated/0/Download";
        Recorder recorder = null;
        try{
            File f = File.createTempFile("qiniu_xxxx", ".tmp");
            Log.d("qiniu", f.getAbsolutePath().toString());
            dirPath = f.getParent();
            //设置记录断点的文件的路径
            recorder = new FileRecorder(dirPath);
        } catch(Exception e) {
            e.printStackTrace();
        }

        final String dirPath1 = dirPath;
        //默认使用 key 的url_safe_base64编码字符串作为断点记录文件的文件名。
        //避免记录文件冲突（特别是key指定为null时），也可自定义文件名(下方为默认实现)：
        KeyGenerator keyGen = new KeyGenerator(){
            public String gen(String key, File file){
                // 不必使用url_safe_base64转换，uploadManager内部会处理
                // 该返回值可替换为基于key、文件内容、上下文的其它信息生成的文件名
                String path = key + "_._" + new StringBuffer(file.getAbsolutePath()).reverse();
                Log.d("qiniu", path);
                File f = new File(dirPath1, UrlSafeBase64.encodeToString(path));

            }
        };

        Configuration config = new Configuration.Builder()
                // recorder 分片上传时，已上传片记录器
                // keyGen 分片上传时，生成标识符，用于片记录器区分是那个文件的上传记录

4).关于从服务器获取Token上传:

Android SDK为客户端SDK，没有包含token生成实现，为了安全，token都建议通过网络从服务端获取，具体生成代码可以参考”java/python/php/ruby/go”等服务端sdk, 其实也比较简单，可以使用okhttp发送一个简单的get请求就可以了，这里以使用SyncHttpClient为例来说明:

package com.example.androidupload;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;
import com.loopj.android.http.SyncHttpClient;
import com.loopj.android.http.TextHttpResponseHandler;
import com.qiniu.android.storage.UpCompletionHandler;
import com.qiniu.android.storage.UpProgressHandler;
import com.qiniu.android.storage.UploadManager;
import com.qiniu.android.storage.UploadOptions;
import com.qiniu.android.utils.UrlSafeBase64;
import org.apache.http.Header;
import org.json.JSONObject;
import java.io.File;
import java.util.UUID;

public class MainActivity extends Activity {

    private UploadManager uploadManager;
    private final String tag = "MainActivity";

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //设置本地上传的文件的路径
        String path ="/storage/emulated/0/Download/DSC_0770.JPG";
        String aaa = UrlSafeBase64.encodeToString(path);
        File file =new File(path);
    }

    private void upload(final String localPath,final String key)
    {
        Thread thread = new Thread()
        {
            @Override
            public void run() {
                super.run();
                SyncHttpClient client = new SyncHttpClient();
                //获取服务端的token的url
                String url = "http://xxxx/xxxx/xxx";
                client.get(url, new TextHttpResponseHandler() {
                    @Override
                    public void onFailure(int i, Header[] headers, String s, Throwable throwable) {
                    }
                    @Override
                    public void onSuccess(int i, Header[] headers, String s) {
                        Log.i(tag,"请求七牛token："+s);
                        JsonParser jsonParser = new JsonParser();
                        JsonElement jsonElement =jsonParser.parse(s);
                        String token = jsonElement.getAsJsonObject().get("uptoken").toString();
                        Log.i(tag,"七牛开始上传"+localPath+"\n"+key+"\n"+token);
                        if(uploadManager==null)
                        {
                            uploadManager = new UploadManager();
                        }
                        UploadOptions uploadOptions = new UploadOptions(null, null, false,
                                new UpProgressHandler() {
                                    @Override
                                    public void progress(String key, double percent) {
                                        Log.i(tag,"a 七牛上传progress:"+percent+"\n"+key);
                                    }
                                }, null);

                        //调用uploadManager上传
                        uploadManager.put(localPath, key, token, new UpCompletionHandler() {
                            @Override
                            public void complete(String key, com.qiniu.android.http.ResponseInfo info, JSONObject response) {
                                Log.i(tag, "a 七牛上传complete:"+key + ",\r\n " + info + ",\r\n " + response);
                            }
                        },uploadOptions);
                    }
                });
            }
        };
        thread.start();
    }
}

5).关于for循环上传:

可以参考demo:

package com.dxy.cloud.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.qiniu.android.http.ResponseInfo;
import com.qiniu.android.storage.UpCompletionHandler;
import com.qiniu.android.storage.UploadManager;
import com.qiniu.android.storage.UploadOptions;
import org.json.JSONObject;

public class MainActivity extends Activity implements View.OnClickListener {

    //指定upToken, 强烈建议从服务端提供get请求获取, 这里为了掩饰直接指定key
    public static String uptoken = "um6IEH7mtwnwkGpjImD08JdxlvViuELhI4mFfoeL:NCnWTr1D3jR_9_dxj6geIgPBQq4=:eyJzY29wZSI6ImFuZHJvaWRkZW1vIiwiZGVhZGxpbmUiOjIzMDk5MjE5MTIsInJldHVybkJvZHkiOiJ7IFwiaGFzaFwiOiQoZXRhZyksXCJrZXlcIjokKGtleSksXCJtaW1lVHlwZVwiOiQobWltZVR5cGUpLCBcImZzaXplXCI6JChmc2l6ZSl9In0=";
    private Button btnUpload;
    private TextView textView;
    private UploadManager uploadManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = (TextView) findViewById(R.id.textView);
        btnUpload = (Button) findViewById(R.id.button);
        btnUpload.setOnClickListener(this);
        //new一个uploadManager类
        uploadManager = new UploadManager();
    }

    @Override
    public void onClick(View v) {
        Log.i("qiniutest", "starting......");
        byte[] data=new byte[]{ 0, 1, 2, 3, 3, 4, 5, 6,0, 1, 2, 3, 4, 5, 6,0, 1, 2, 3, 4, 5, 6,0, 1, 2, 3, 4, 5, 6,0, 1, 2, 3, 4, 5, 6,0, 1, 2, 3,};

       for(int i=0;inew UpCompletionHandler() {
                public void complete(String k, ResponseInfo rinfo, JSONObject response) {
                    String s = k + ", "+ rinfo + ", " + response;
                    Log.i("qiniutest", s);
                    String key = getKey(k, response);
                    String o = hint.getText() + "\r\n\r\n";
                    hint.setText(o + s + "http://xm540.com1.z0.glb.clouddn.com/" + key);
                }
            }, new UploadOptions(null, "test-type", true, null, null));
        }
    }
}

6).常见的返回的状态码:

使用七牛 Android sdk 的时候， 如果使用方式不正确，会返回一些对应的错误码。
具体可以参考源码：
https://github.com/qiniu/android-sdk/blob/c4cd1437aa1f2a0d68122e46b83580facdf1b74a/library/src/main/java/com/qiniu/android/http/ResponseInfo.java

public static final int ZeroSizeFile = -6;
public static final int InvalidToken = -5;
public static final int InvalidArgument = -4;
public static final int InvalidFile = -3;
public static final int Cancelled = -2;
public static final int NetworkError = -1;
public static final int TimedOut = -1001;
public static final int UnknownHost = -1003;
public static final int CannotConnectToHost = -1004;
public static final int NetworkConnectionLost = -1005;

7).关于混淆配置:

混淆处理 对七牛的SDK不需要做特殊混淆处理，混淆时将七牛相关的包都排除就可以了。

在Android Studio中，混淆配置在 proguard-rules.pro 里面加上下面几行混淆代码就行：

-keep class com.qiniu.**{*;}
-keep class com.qiniu.**{public <init>();}
-ignorewarnings

注意：-ignorewarnings这个也是必须加的，如果不加这个编译的时候可能是可以通过的，但是release的时候还是会出现错误。

对于Eeclipse中也是一样的，在proguard-project.txt 文件附件同样的排除代码就可以了

-keep class com.qiniu.**{*;}
-keep class com.qiniu.**{public <init>();}
-ignorewarnings

8).为什么进度会在95% 停很久:

因为上传进度是用sdk写入socket的 字节数/总字节数 作为进度，但写入socket不等于服务器收到并且处理完成，中间还有一段时间，如果只是用字节数就会出现更怪异的情况，在100% 停留很久，所以综合考虑就使用了 95%这个值.

9).华北地区上传域名需要修改:

华北地区的空间需要修改下上传域名:
https://support.qiniu.com/hc/kb/article/169006/?from=draft
不然会报错:
incorrect zone please use up-z1.qiniu.com

new uploadManager的时候传入这个配置修改上传的zone为zone1就可以了就可以了：
uploadManager = new UploadManager(new Configuration.Builder().zone(Zone.zone1).build());
