ionic android升级检查

坑:

放到cordova.file.DataDirectory下载异常? 只好cordova.file.externalDataDirectory

代码

        // 检查更新
        $scope.appUpdateCheck = function(init) {
            var init = init || 0;

            // appUpdateService.showUpdateConfirm({});
            // return;

            VersionService.get({ platform: ionic.Platform.platform() }, function(resp) {
                // alert(JSON.stringify(resp))
                if (resp.code == '000') {
                    // alert(resp.data.version)
                    // alert($cordovaAppVersion.getVersionNumber())
                    // alert($cordovaAppVersion.getVersionCode())

                    cordova.getAppVersion.getVersionNumber(function(version) {
                        // alert(version)
                        if (version == resp.data.version) {
                            if (!init) {
                                messageService.show('当前已是最新版本');
                            }
                            return;
                        }

                        $scope.hasNewVersion = 1;
                        $scope.device_items[1].name = $sce.trustAsHtml('升级检查<font style="color:#FD1F38"> - New!</font>');

                        if (!init) {
                            appUpdateService.showUpdateConfirm(resp.data);
                        }
                    });
                } else {
                    messageService.show(resp.msg);
                }
            });
        }
