对于做Android的朋友来说#xff0c;APP更新功能再常见不过了#xff0c;因为平台更新审核时间较长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 二、实现步骤
1.AndroidManifest权限申请 !--外置存储卡写入权限--uses-permission android:nameandroid.permission.WRITE_EXTERNAL_STORAGE /!--请求安装APK的权限--uses-permission android:nameandroid.permission.REQUEST_INSTALL_PACKAGES /!--读取删除SD卡权限--uses-permission android:nameandroid.permission.READ_EXTERNAL_STORAGE /!--修改删除SD卡权限--uses-permissionandroid:nameandroid.permission.MOUNT_UNMOUNT_FILESYSTEMStools:ignoreProtectedPermissions /uses-permission android:nameandroid.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 --providerandroid:nameandroidx.core.content.FileProviderandroid:authorities这里是applicationId也就是包名.fileproviderandroid:exportedfalseandroid:grantUriPermissionstruemeta-dataandroid:nameandroid.support.FILE_PROVIDER_PATHSandroid:resourcexml/provider_paths //provider//这里的provider_paths文件放在xml文件下代码如下
?xml version1.0 encodingutf-8?
paths!--拍照需要的路径--external-pathnamecomxf.activity.provider.downloadpath. /external-files-path nameextfiles pathautoupdatecache/ /external-cache-path nameextcachs pathautoupdatecache/ /cache-path nameintcachs pathautoupdatecache/ /pathsexternal-path path namedownload//paths/paths2.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Overridepublic 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(thisSetUpActivity)) {val myDialog UpdateappUtilDialog()myDialog.initDialog(thisSetUpActivity, 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(thisSetUpActivity,Manifest.permission.WRITE_EXTERNAL_STORAGE) ! PackageManager.PERMISSION_GRANTED) {// 申请读写内存卡内容的权限ActivityCompat.requestPermissions(thisSetUpActivity, arrayOf(Manifest.permission.WRITE_EXTERNAL_STORAGE), 123)} else {//授权成功if (FileUtils.createOrExistsDir(NetConst.baseFileName)) {val mUpdateManger DownloadAppUtils(thisSetUpActivity, versionbean.file_url, versionbean)mUpdateManger.checkUpdateInfo()}}} else {//授权成功if (FileUtils.createOrExistsDir(NetConst.baseFileName)) {val mUpdateManger DownloadAppUtils(thisSetUpActivity, 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: ArrayString?,grantResults: IntArray) {super.onRequestPermissionsResult(requestCode, permissions, grantResults)when (requestCode) {123 - {//授权成功if (FileUtils.createOrExistsDir(NetConst.baseFileName)) {val mUpdateManger DownloadAppUtils(thisSetUpActivity, versionbean.file_url, versionbean)mUpdateManger.checkUpdateInfo()}}}}3.有版本更新弹框UpdateappUtilDialog 1.util代码 /*** Created by caoliulang* ❤* Creation time :2025/2/24* ❤* Function 更新app的Dialog*/

其实这功能挺简单的就是里面细节太多首先AndroidManifest加权限还要加providerprovider里面记得更改包名下载util里面的报名也是一样。其次判断版本是否更新最后更新下载安装即可得吃。
