Android进阶之路 - 版本检测且自动升级
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：
-
当前项目内进行版本升级，apk下载替换升级
-
跳转对应的app应用商店详情页，由用户自己下载
Effect :
权限导入
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();
}
CustomDialog

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
2.找到Xml下的 file_path.xml 修改代码
file_path.xml :
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);
}
借鉴文章：
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();
}
}
