在Android服务动态抓取拍摄的图像路径 [英] Fetching captured images path dynamically in services in android

问题描述

在我的应用我有硬coded到拍摄的摄像机图像的路径。然而，这并不适用于所有设备，因为图像的存储路径是不同的设备不同。有没有办法来动态获取这条道路，这将是适用于所有设备？

这是我曾尝试：

 如果（externalStorageState.equals（Environment.MEDIA_MOUNTED）        || externalStorageState.equals（Environment.MEDIA_UNMOUNTED）        || externalStorageState
                .equals（Environment.MEDIA_MOUNTED_READ_ONLY））{
    文件路径=环境
            .getExternalStoragePublicDirectory（Environment.DIRECTORY_DCIM                    +/摄像机）; ////////// ----拍摄图像的路径    Log.d（经营者，路径：+路径）;    如果（path.exists（））{        如果（path.isDirectory（））{            FO =新FileObserver（path.toString（）                    FileObserver.CLOSE_WRITE）{                @覆盖
                公共无效的onEvent（INT事件，字符串路径）{                    SimpleDateFormat的sdfDateT =新的SimpleDateFormat（                            YY-MM-DD HH：MM：SS，Locale.US）;                    串ST = sdfDateT.format（系统                            .currentTimeMillis（））;
                    Log.d（经营者，事件）;                    Log.d（经营者，纬度：+纬度++LNG                            + LNG ++的位置：+休闲旅客提供++时间：+ ST）;                    ptd.insert（ST，将String.valueOf（LAT），将String.valueOf（LNG），休闲旅客提供）;                }
            };
 

解决方案

使用 getExternalStorageDirectory（）如果API水平低于7，然后追加 /图片来得到的照片存储路径。

有关API级别> 7使用 getExternalStoragePublicDirectory（DIRECTORY_PICTURES）。结果

In my app I have hard-coded a path to captured camera images. However this do not work for all devices, because the storage path for images is different for different devices. Is there a way to dynamically get this path which will be valid for all devices?

This is what I have tried:

    if (externalStorageState.equals(Environment.MEDIA_MOUNTED)

        || externalStorageState.equals(Environment.MEDIA_UNMOUNTED)

        || externalStorageState
                .equals(Environment.MEDIA_MOUNTED_READ_ONLY)) {


    File path = Environment
            .getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM

                    + "/Camera");//////////----path of captured images

    Log.d("operator", " path: " + path);

    if (path.exists()) {

        if (path.isDirectory()) {

            fo = new FileObserver(path.toString(),

                    FileObserver.CLOSE_WRITE) {

                @Override
                public void onEvent(int event, String path) {

                    SimpleDateFormat sdfDateT = new SimpleDateFormat(

                            "yy-MM-dd HH:mm:ss", Locale.US);

                    String st = sdfDateT.format(System

                            .currentTimeMillis());
                    Log.d("operator", "in event");

                    Log.d("operator", "lat: " + lat + " " + "lng: "

                            + lng + " " + "location: " + addre + " " + "time: " + st);

                    ptd.insert(st, String.valueOf(lat), String.valueOf(lng), addre);

                }
            };

解决方案

Use getExternalStorageDirectory() if API level is below 7 and then append /Pictures to get the path of Photos storage.

for API level > 7 use getExternalStoragePublicDirectory (DIRECTORY_PICTURES).
