写项目，版本升级这种功能用到的地方太多了~

文章结构 ：

  • 俩种升级方式
  • 所遇问题解析

俩种升级方式：

这里写图片描述

权限导入

    <uses-permission android:name="android.permission.READ_PROFILE"/>
    <uses-permission android:name="android.permission.WRITE_PROFILE"/>
    <uses-permission android:name="android.permission.INTERNET"/>

方法归纳

  • 获取版本号
   /**
     * 返回版本号
     * 对应build.gradle中的versionCode
     * @param context context
     * @return String
     */
    public static String getVersionCode(Context context) {
        String versionCode = "";
        try {
            PackageManager packageManager = context.getPackageManager();
            PackageInfo packInfo = packageManager.getPackageInfo(context.getPackageName(), 0);
            versionCode = String.valueOf(packInfo.versionCode);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return versionCode;
    }
  • 根据当前与线上版本进行比较，然后弹出是否升级提示框(提示框可用系统提供的，也可以用自定义的，这个主要看UI,UE如何决定，下面附带我的弹框)
/**
     * 弹出提示更新的dialog
     */
    private void showUpdateDialog() {
        CustomDialog customDialog = new CustomDialog(SettingActivity.this);
        customDialog.setMsg("检查到有最新版本,是否更新?");
        customDialog.setTitle("版本更新提示");
        customDialog.setCancelText("暂不更新");
        customDialog.setConfirmText("立刻更新");
        customDialog.setOnSureClickListener(new CustomDialog.OnSureClickListener() {
            @Override
            public void sureClick() {
                //下载APK
                downloadApk();
            }
        });
        customDialog.show();
    }

    }

所遇问题解析：

  • 当Android版本为7.0或7.0以上系统的时候，安装Apk时报出FileUriExposedException

解决方案：
1.清单文件加入以下代码

  <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="我们的包名.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths"/>
        </provider>

2.找到Xml下的 file_path.xml 修改代码
这里写图片描述

file_path.xml :

<?xml version="1.0" encoding="utf-8"?>
<paths>

    <external-path path="Android/data/我们的包名/" name="files_root" />
    <external-path path="." name="external_storage_root" />
</paths>

3.修改 installApk 方法

 /**
     * 下载完成,提示用户安装  
     * file 为File文件 或 fileName 主要看你上一个方法有没有转文件名
     */
    private void installApk(File file) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            Uri contentUri = FileProvider.getUriForFile(this, "我们的包名.fileprovider", file);
            intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
        } else {
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.setDataAndType(Uri.parse("file://" + file),
                    "application/vnd.android.package-archive");
        }
        startActivityForResult(intent, 119);
    }

Android 7.0 安装Apk时报错FileUriExposedException 解决

  • 安装完成，重新启动app

注意 ：
Android 部分手机通过下面这个方法无法实现跳转，可能是6.0，7.0这种系统原因，可能是机型的问题

步骤：
1.安装完成之后startActivityForResult，如：

  startActivityForResult(intent, 119);

2.重写onActivityReenter

  @Override
    public void onActivityReenter(int resultCode, Intent data) {
        super.onActivityReenter(resultCode, data);
        if (resultCode == 119) {
            startAPP("我们的包名");
        }
    }

3.app唤醒方法

public void startAPP(String appPackageName) {
        try {
            Intent intent = this.getPackageManager().getLaunchIntentForPackage(appPackageName);
            startActivity(intent);
        } catch (Exception e) {
            Toast.makeText(this, "没有安装", Toast.LENGTH_LONG).show();
        }
    }
