### Android 新版本的出现 ，适配Android8.0未知来源应用安装权限处理 ###

#### 1、在清单文件中增加请求安装权限 ####

`<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />`

private void showChangCityDialog() {
        
        CustomDialog.Builder builder = new CustomDialog.Builder(mContext);
        builder.setTitleStr("提示");
        builder.setBodysStr("安装应用需要打开未知来源权限，请去设置中开启权限");
        builder.setLeftbtnStr("取消");
        builder.setRightbtnStr("设置");
        builder.setLeftBtnColor(R.color.color_333333);
        builder.setrRightBtnColor(R.color.C6);
        builder.setOnClickListener(new CustomDialog.DialogOnItemClickListener() {
            @Override
            public void leftClick() {
                finish();
            }
    
            @Override
            public void rightClick() {
                //兼容8.0
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    boolean hasInstallPermission = mContext.getPackageManager().canRequestPackageInstalls();
                    if (!hasInstallPermission) {
                        startInstallPermissionSettingActivity();
                    } else {
                        //再次执行安装流程，包含权限判等
                        if (!TextUtils.isEmpty(appUrl)) {
                            //再次启动安装流程
                            installApk(appUrl);
                        }
                    }
                }
            }
        });
        builder.create().show();
    }

/**
     * 跳转到设置-允许安装未知来源-页面
     */
    @RequiresApi(api = Build.VERSION_CODES.O)
    private void startInstallPermissionSettingActivity() {
    
        Uri packageURI = Uri.parse("package:" + BuildConfig.APPLICATION_ID);
        //注意这个是8.0新API
        Intent intent = new Intent(Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES, packageURI);
        startActivityForResult(intent, 1);
    
    }
