app 打开办公软件的

通过Android手机打开office的方法

通过webview的形式打开

google和微软有在线预览office软件的url

google：docs.google.com/viewer?url=…

微软：view.officeapps.live.com/op/view.asp…

对文档完全没有安全方面的考虑，建议使用微软的在线解析，亲测可用，谷歌的在国内被封了

WebView urlWebView = (WebView) findViewById(R.id.containWebView);

urlWebView.setVisibility(View.VISIBLE);

mLvAttach.setVisibility(View.GONE);

urlWebView.setWebViewClient(newAppWebViewClients());

urlWebView.getSettings().setJavaEnabled(true);

urlWebView.getSettings().setUseWideViewPort(true);

urlWebView.loadUrl("xxxx”);

下载到本地通过intent打开

val intent = Intent("android.intent.action.VIEW")
intent.addCategory("android.intent.category.DEFAULT")
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
var uri:Uri
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
    intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION;
    //记得修改com.xxx.fileprovider与androidmanifest相同
    uri =
        FileProvider.getUriForFile(context!!,"com.xxx.fileprovider",File(path))
    intent.setDataAndType(uri,"application/vnd.android.package-archive");
}else{
    uri = Uri.parse("file://$path")
}
intent.setDataAndType(uri, "application/*")
this.startActivity(intent)

我们需要了解 MIME_MapTable是所有文件的后缀名所对应的MIME类型

备注

对于面向 Android 7.0 的应用，Android 框架执行的 StrictMode API 政策禁止在您的应用外部公开 file://URI。传递软件包网域外的 file://URI 可能给接收器留下无法访问的路径。因此，尝试传递 file://URI会触发 FileUriExposedException。分享私有文件内容的推荐方法是使用 FileProvider
