自己用系统的DownloadManager工具封装了一个版本更新帮助类，代码如下：

1.功能具体实现的java代码

    private static final String TAG = "VersionUpdataHelper";    private final String DOWNLOAD_FILE_NAME;    private Context mContext;    private DownloadManager mDownloadManager;    private String mUrl;    private long mDownloadId;    private CompleteReceiver mReceiver;    private int mCancleDownload;    private CustomDialog mDialog;    private CustomDialog.Builder mBuilder;    private boolean mCancelable;    private String mUpdateInfo;    public VersionUpdataHelper(Activity activity, String url) {        this(activity, url, true);    }    public VersionUpdataHelper(Activity activity, String url, boolean cancelable) {        this(activity, url, cancelable, "");    }    public VersionUpdataHelper(Activity activity, String url, boolean cancelable, String info){        DOWNLOAD_FILE_NAME = System.currentTimeMillis() + ".apk";        if (activity == null || activity.isFinishing()){            return;        }        mContext = activity;        mUrl = url;        mCancelable = cancelable;        mUpdateInfo = info;        showNewVersionDialog();    }    private void showNewVersionDialog() {        String message = "发现新版本，是否下载并更新...";        if (!TextUtils.isEmpty(mUpdateInfo)){            message = message + "\n\n" + mUpdateInfo;            Lg.i(TAG, "---message===" + message);        }        mBuilder = new CustomDialog.Builder(mContext);        mBuilder.setMessage(message)                .setPositiveButton("确定", new DialogInterface.OnClickListener() {                    @Override                    public void onClick(DialogInterface dialog, int which) {                        dialog.dismiss();                        startDownload(mUrl);                        initDownloadingDialog();                        mDialog.show();                        mCancleDownload = 0;                    }                });        if (mCancelable) {            mBuilder.setNegativeButton("取消", new DialogInterface.OnClickListener() {                @Override                public void onClick(DialogInterface dialog, int which) {                    dialog.dismiss();                }            });        }        mDialog = mBuilder.create();        mDialog.setCancelable(false);        mDialog.show();    }    private void initDownloadingDialog() {        mCancleDownload = 0;        mBuilder = new CustomDialog.Builder(mContext);        mBuilder.setMessage("软件更新中...");        mBuilder.setNegativeButton("取消", new DialogInterface.OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                if (mCancelable) {                    mDownloadManager.remove(mDownloadId);                    dialog.dismiss();                    mCancleDownload = 1;                    unregisterUpdataReceiver();                }            }        });        mDialog = mBuilder.create();        mReceiver = new CompleteReceiver();        mContext.registerReceiver(mReceiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));    }    public void unregisterUpdataReceiver() {        mContext.unregisterReceiver(mReceiver);    }    private void startDownload(String url) {        mDownloadManager = (DownloadManager) mContext.getSystemService(Context.DOWNLOAD_SERVICE);        Uri resource = Uri.parse(url);        DownloadManager.Request request = new DownloadManager.Request(resource);

       String mimeString = mimeTypeMap.getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(url));        request.setMimeType(mimeString);        request.setShowRunningNotification(true);        request.setVisibleInDownloadsUi(true);        request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, DOWNLOAD_FILE_NAME);        mDownloadId = mDownloadManager.enqueue(request);        mContext.getContentResolver().registerContentObserver(Uri.parse("content://downloads/"),                true, new DownloadObserver(handler, mContext, mDownloadId));

       public CustomDialog(Context context) {            super(context);        }        public CustomDialog(Context context, int theme) {            super(context, theme);        }        @Override        protected void onCreate(Bundle savedInstanceState) {            super.onCreate(savedInstanceState);            setContentView(R.layout.dialog_custom);            mMessageTv = (TextView) findViewById(R.id.tv_dialog_message);            mPositiveBtn = (Button) findViewById(R.id.btn_dialog_positive);            mNegativeBtn = (Button) findViewById(R.id.btn_dialog_negative);            mButtonDividerView = findViewById(R.id.view_dialog_button_divider);            if (message != null) {                mMessageTv.setText(message);            }            if (positiveButtonText != null) {                mPositiveBtn.setText(positiveButtonText);                if (positiveButtonClickListener != null) {                    mPositiveBtn.setOnClickListener(new View.OnClickListener() {                        @Override                        public void onClick(View v) {                            positiveButtonClickListener.onClick(CustomDialog.this, Dialog.BUTTON_POSITIVE);                        }                    });                }            } else {                mPositiveBtn.setVisibility(View.GONE);                mButtonDividerView.setVisibility(View.GONE);            }            if (negativeButtonText != null) {                mNegativeBtn.setText(negativeButtonText);

                       }                    });                }            } else {                mNegativeBtn.setVisibility(View.GONE);                mButtonDividerView.setVisibility(View.GONE);            }        }        private void setMessage(String msg) {            message = msg;        }        private void setPositiveButtonText(String text) {            positiveButtonText = text;        }        private void setNegativeButtonText(String text) {            negativeButtonText = text;        }        private void setOnNegativeListener(OnClickListener listener) {            negativeButtonClickListener = listener;        }        private void setOnPositiveListener(OnClickListener listener) {            positiveButtonClickListener = listener;        }        public static class Builder {            private Context context;            private String message;            private String positiveButtonText;            private String negativeButtonText;            private OnClickListener positiveButtonClickListener;            private OnClickListener negativeButtonClickListener;            public Builder(Context context) {                this.context = context;            }            public Builder setMessage(String message) {                this.message = message;                return this;            }            public Builder setMessage(int message) {                this.message = context.getString(message);                return this;            }            public Builder setPositiveButton(int positiveButtonText,                                             OnClickListener listener) {                return setPositiveButton(context.getString(positiveButtonText), listener);            }            public Builder setPositiveButton(String positiveButtonText,                                             OnClickListener listener) {                this.positiveButtonText = positiveButtonText;                this.positiveButtonClickListener = listener;                return this;            }            public Builder setNegativeButton(int negativeButtonText,                                             OnClickListener listener) {                return setNegativeButton(context.getString(negativeButtonText), listener);            }            public Builder setNegativeButton(String negativeButtonText,                                             OnClickListener listener) {                this.negativeButtonText = negativeButtonText;                this.negativeButtonClickListener = listener;                return this;            }            public CustomDialog create() {                CustomDialog dialog = new CustomDialog(context);                dialog.setCancelable(false);                dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);                dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);                dialog.setMessage(message);                dialog.setNegativeButtonText(negativeButtonText);                dialog.setPositiveButtonText(positiveButtonText);                dialog.setOnNegativeListener(negativeButtonClickListener);                dialog.setOnPositiveListener(positiveButtonClickListener);                return dialog;            }        }    }}

2.用到的布局文件dialog_custom.xml，放在layout目录下

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent">    <LinearLayout        android:layout_width="300dp"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:background="@drawable/dialog_background"        android:orientation="vertical">        <TextView            android:id="@+id/tv_dialog_message"            android:layout_width="match_parent"            android:layout_height="100dp"            android:gravity="center"            android:text="message"            android:textColor="#333333"            android:textSize="16sp" />        <View            android:layout_width="match_parent"            android:layout_height="1dp"            android:background="#e8e8e8" />        <LinearLayout            android:layout_width="match_parent"            android:layout_height="50dp"            android:orientation="horizontal">            <Button                android:id="@+id/btn_dialog_positive"                android:layout_width="0px"                android:layout_height="match_parent"                android:layout_weight="1"                android:background="@null"                android:text="todo"                android:textColor="#EE6911"                android:textSize="16sp" />            <View                android:id="@+id/view_dialog_button_divider"                android:layout_width="1dp"                android:layout_height="match_parent"                android:background="#e8e8e8" />            <Button                android:id="@+id/btn_dialog_negative"                android:layout_width="0px"                android:layout_height="match_parent"                android:layout_weight="1"                android:background="@null"                android:text="cancel"                android:textColor="#EE6911"                android:textSize="16sp" />        </LinearLayout>    </LinearLayout></FrameLayout>

3.用到的背景设置dialog_background.xml文件，放在drawable目录下

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android">    <solid android:color="@color/sweet_dialog_bg_color" />    <corners android:radius="6dp"/></shape>

使用说明书
* 说明：版本更新帮助类，负责下载apk文件并打开安装
* 用法：直接new本类，构造方法里分别传
* Context Activity的context
* String apk下载地址
* boolean 允许跳过本次更新
* 示例：
* 普通版本更新 new VersionUpdataHelper(MainActivity.this, info.getUrl());
* 强制版本更新 new VersionUpdataHelper(MainActivity.this, info.getUrl(), false);
* 测试过红米note 4.4，三星 5.1.1，华为 6.0系统
