通过OKhttp3进行下载实现版本更新

===========================

一：配置：
build:

implementation 'com.squareup.okhttp3:okhttp:3.8.1'    implementation 'com.squareup.okio:okio:1.7.0'

这个是我的版本，根据自己项目调整。**AndroidManifest.xml:**

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

二：代码:
首先是更新实体Bean-UpdateBean:

package com.ma.update;public class UpdateBean {    private String title;    private String message;    private int versionCode;    private String versionName;    private String url;    public String getVersionName() {        return versionName;    }    public void setVersionName(String versionName) {        this.versionName = versionName;    }    public String getUrl() {        return url;    }    public void setUrl(String url) {        this.url = url;    }    public String getTitle() {        return title;    }    public void setTitle(String title) {        this.title = title;    }    public String getMessage() {        return message;    }    public void setMessage(String message) {        this.message = message;    }    public int getVersionCode() {        return versionCode;    }    public void setVersionCode(int versionCode) {        this.versionCode = versionCode;    }}

网络工具类：

 /**     * 下载apk     */    public static void httpDownLoadApk(String url, Context context, Map BodyParams, okhttp3.Callback callback) {        // 打印日志        getHttpUrl(url, BodyParams);        OkHttpClient  mOkHttpClient = builder.build();        Request request = new Request.Builder()                .url(url)                .build();        Call call = mOkHttpClient.newCall(request);        call.enqueue(callback);    }

更新对话框：

**package com.ma.update;import android.app.Dialog;import android.content.Context;import android.view.KeyEvent;import android.view.View;import android.view.ViewGroup;import android.widget.Button;import android.widget.LinearLayout;import android.widget.TextView;/** * Created by mjm on 2017/5/17. * 更新对话框 */public class UpdateDialog extends Dialog implements View.OnClickListener {    private UpdateDialogOperate aDialogOperate; // 操作接口    private Context context;    private TextView ver;    private TextView content;    private Button update_ok;    private Button upadte_cancle;    private UpdateBean upadtebean;    private TextView tip;    public UpdateDialog(Context context) {        super(context, R.style.common_dialog);        this.context = context;        this.setContentView(R.layout.dialog_update);        ver = (TextView) findViewById(R.id.update_ver);        content = (TextView) findViewById(R.id.update_content);        update_ok = (Button) findViewById(R.id.update_btn_ok);        upadte_cancle = (Button) findViewById(R.id.update_btn_cancle);        tip = (TextView) findViewById(R.id.update_tip);        update_ok.setOnClickListener(this);        upadte_cancle.setOnClickListener(this);    }    public void setData(UpdateBean upadtebean, boolean flag, UpdateDialogOperate aDialogOperate) {        this.aDialogOperate = aDialogOperate;        this.upadtebean = upadtebean;        upadte_cancle.setVisibility(View.VISIBLE);        tip.setVisibility(View.GONE);        //关闭以后再说。。。        upadte_cancle.setVisibility(View.GONE);        update_ok.setVisibility(View.VISIBLE);        ver.setText(upadtebean.getVersionName());        content.setText(upadtebean.getMessage());        this.setCancelable(false);    }    @Override    public void onClick(View v) {        switch (v.getId()) {            case R.id.update_btn_cancle:                aDialogOperate.executeCancel("");                break;            case R.id.update_btn_ok:                aDialogOperate.executeCommit("");                break;            default:                break;        }    }    @Override    public boolean onKeyDown(int keyCode, KeyEvent event) {        return super.onKeyDown(keyCode, event);    }}**

更新代码：

public static int UpdateVersion(final Context context, final UpdateBean updateBean) {        String packageName = context.getPackageName();        int nowCode = getVersionCode(context);//手机端的版本        int newCode = updateBean.getVersionCode();        if (nowCode < newCode) {//小于最新版本号            checkPermission(context, updateBean);        } else {            Log.e("MA", "已经是最新版本");//            ToastUtils.showMessage("已经是最新的版本");        }        return 0;    }    public static void checkPermission(final Context context, final UpdateBean updateBean) {        if (ContextCompat.checkSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE)                != PackageManager.PERMISSION_GRANTED) {            //申请WRITE_EXTERNAL_STORAGE权限            ActivityCompat.requestPermissions((MainActivity) context, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},                    1000);            return;        } else {            showUpdateDialog(context, updateBean);            //        }    }    public static void showUpdateDialog(final Context context, final UpdateBean updateBean) {        final UpdateDialog updateDialog = new UpdateDialog(context);        updateDialog.setData(updateBean, true, new UpdateDialogOperate() {            @Override            public void executeCancel(String text) {                updateDialog.cancel();            }            @Override            public void executeCommit(String text) {                downFile(updateBean.getUrl(), context);                updateDialog.cancel();            }        });        updateDialog.show();    }

适配7.0安装：

public static void installApk(File file, Context context) {        Intent intent = new Intent();        intent.setAction(Intent.ACTION_VIEW);        if (Build.VERSION.SDK_INT > 23) {             Uri apkUri =                    FileProvider.getUriForFile(context, "**包名**.fileprovider", file);            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);            intent.setDataAndType(apkUri, "application/vnd.android.package-archive");        } else {            intent.setDataAndType(Uri.fromFile(file),                    "application/vnd.android.package-archive");        }        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        context.startActivity(intent);    }

AndroidManifase.xml:

"android.support.v4.content.FileProvider"            android:authorities="包名".fileprovider"            android:exported="false"            android:grantUriPermissions="true">            "                android:resource="@xml/filepaths" />
