前言

对于做Android的朋友来说，APP更新功能再常见不过了，因为平台更新审核时间较长，所以现在很多都会通过接口更新，这里就记录一下吧，欢迎各位讨论。

一、效果图

在这里插入图片描述

二、实现步骤

1.AndroidManifest权限申请

    <!--外置存储卡写入权限-->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
     <!--请求安装APK的权限-->
    <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
    <!--读取删除SD卡权限-->
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <!--修改删除SD卡权限-->
    <uses-permission
        android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"
        tools:ignore="ProtectedPermissions" />
    <uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE" />
    //application标签下加如下代码
     <!-- 安卓7.0安装时需要,拍照需要的临时权限 -->
        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="这里是applicationId也就是包名.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths" />
        </provider>

//这里的provider_paths文件放在xml文件下，代码如下：
<?xml version="1.0" encoding="utf-8"?>
<paths>
    <!--拍照需要的路径-->
    <external-path
        name="comxf.activity.provider.download"
        path="." />

    <external-files-path name="extfiles" path="autoupdatecache/" />
    <external-cache-path name="extcachs" path="autoupdatecache/" />
    <cache-path name="intcachs" path="autoupdatecache/" />
    <paths>
        <external-path path="" name="download"/>
    </paths>

</paths>

2.activity实现

1.通过接口获取Javabean对象

    public Integer id;
    public String version_name;//App版本名
    public Integer version_code;//版本编号
    public String content;//版本更新内容
    public String is_must_update;//是否需要强更新(0:否，1:是)
    public String file_url;//app包的下载地址

    @Override
    public String toString() {
        return "VersionUpgradeBean{" +
                "id=" + id +
                ", version_name='" + version_name + '\'' +
                ", version_code=" + version_code +
                ", content='" + content + '\'' +
                ", is_must_update='" + is_must_update + '\'' +
                ", file_url='" + file_url + '\'' +
                '}';
    }

2.获取到版本号后判断是否高于当前版本

  if (versionbean.version_code > MyApplication.getVersionCode(this@SetUpActivity)) {
            val myDialog = UpdateappUtilDialog()
            myDialog.initDialog(this@SetUpActivity, versionbean)
            myDialog.buttonClickEvent(object : UpdateappUtilDialog.DialogButtonClick {
                override fun cilckComfirmButton(view: View?) {
                    myDialog.Dismiss()
                    //6.0才用动态权限
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        if (ContextCompat.checkSelfPermission(
                                this@SetUpActivity,
                                Manifest.permission.WRITE_EXTERNAL_STORAGE
                            ) != PackageManager.PERMISSION_GRANTED
                        ) {
                            // 申请读写内存卡内容的权限
                            ActivityCompat.requestPermissions(
                                this@SetUpActivity, arrayOf(
                                    Manifest.permission.`WRITE_EXTERNAL_STORAGE`
                                ), 123
                            )
                        } else {
                            //授权成功
                            if (FileUtils.createOrExistsDir(NetConst.baseFileName)) {
                                val mUpdateManger = DownloadAppUtils(
                                    this@SetUpActivity, versionbean.file_url, versionbean
                                )
                                mUpdateManger.checkUpdateInfo()
                            }
                        }
                    } else {
                        //授权成功
                        if (FileUtils.createOrExistsDir(NetConst.baseFileName)) {
                            val mUpdateManger = DownloadAppUtils(
                                this@SetUpActivity, versionbean.file_url, versionbean
                            )
                            mUpdateManger.checkUpdateInfo()
                        }
                    }
                }

                override fun cilckCancleButton(view: View?) {
                    //点击取消按钮
                    myDialog.Dismiss()
                }
            })
        }

3.用户权限结果处理

  /**
     * todo 对用户权限授予结果处理
     *
     * @param requestCode  权限要求码，即我们申请权限时传入的常量 如： TAKE_PHOTO_PERMISSION_REQUEST_CODE
     * @param permissions  保存权限名称的 String 数组，可以同时申请一个以上的权限
     * @param grantResults 每一个申请的权限的用户处理结果数组(是否授权)
     */
    override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<String?>,
        grantResults: IntArray
    ) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        when (requestCode) {
            123 -> {
                //授权成功
                if (FileUtils.createOrExistsDir(NetConst.baseFileName)) {
                    val mUpdateManger = DownloadAppUtils(
                        this@SetUpActivity, versionbean.file_url, versionbean
                    )
                    mUpdateManger.checkUpdateInfo()
                }
            }
        }
    }

3.有版本更新弹框UpdateappUtilDialog

1.util代码

        textvs.setText(upbean.version_name);
        tv_cancel = window.findViewById(R.id.tv_cancel);
        //1不强制更新  2 强制更新
//        if(upbean.getUpdateType().equals("2")){
//            firstBtn.setVisibility(View.GONE);
//        }

//        //不关闭弹窗也能点击外部事件
//        alertDialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
        String isqg = upbean.is_must_update + "";
        if (isqg.equals("true")) {
            tv_cancel.setVisibility(View.GONE);
        } else {
            tv_cancel.setVisibility(View.VISIBLE);
        }
    }

    public void cilckEvent() {
//        if (firstBtn != null) {
//            firstBtn.setOnClickListener(new View.OnClickListener() {
//                @Override
//                public void onClick(View v) {
//                    alertDialog.dismiss();
//                    mClick.cilckCancleButton(v);
//                }
//            });
        secondBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
//                    alertDialog.dismiss();
                mClick.cilckComfirmButton(v);
            }
        });
        tv_cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mClick.cilckCancleButton(view);
            }
        });
//        }
    }

    public void Dismiss() {
        if (null != alertDialog) {
            alertDialog.dismiss();
        }
    }

}
