I found very simple solution for this question....So I posted it here to help my friends who have problem like me to get Geo location from Picture.
我为这个问题找到了非常简单的解决方案......所以我把它贴在这里是为了帮助像我这样有问题的朋友从图片中获取地理位置。
Bundle bundle = getIntent().getExtras();
if(null != bundle)
{
String filepath = bundle.getString(FILE_PATH_KEY);
try
{
ExifInterface exif = new ExifInterface(filepath);
StringBuilder builder = new StringBuilder();
builder.append("Date & Time: " + getExifTag(exif,ExifInterface.TAG_DATETIME) + "\n\n");
builder.append("Flash: " + getExifTag(exif,ExifInterface.TAG_FLASH) + "\n");
builder.append("Focal Length: " + getExifTag(exif,ExifInterface.TAG_FOCAL_LENGTH) + "\n\n");
builder.append("GPS Datestamp: " + getExifTag(exif,ExifInterface.TAG_FLASH) + "\n");
builder.append("GPS Latitude: " + getExifTag(exif,ExifInterface.TAG_GPS_LATITUDE) + "\n");
builder.append("GPS Latitude Ref: " + getExifTag(exif,ExifInterface.TAG_GPS_LATITUDE_REF) + "\n");
builder.append("GPS Longitude: " + getExifTag(exif,ExifInterface.TAG_GPS_LONGITUDE) + "\n");
builder.append("GPS Longitude Ref: " + getExifTag(exif,ExifInterface.TAG_GPS_LONGITUDE_REF) + "\n");
builder.append("GPS Processing Method: " + getExifTag(exif,ExifInterface.TAG_GPS_PROCESSING_METHOD) + "\n");
builder.append("GPS Timestamp: " + getExifTag(exif,ExifInterface.TAG_GPS_TIMESTAMP) + "\n\n");
builder.append("Image Length: " + getExifTag(exif,ExifInterface.TAG_IMAGE_LENGTH) + "\n");
builder.append("Image Width: " + getExifTag(exif,ExifInterface.TAG_IMAGE_WIDTH) + "\n\n");
builder.append("Camera Make: " + getExifTag(exif,ExifInterface.TAG_MAKE) + "\n");
builder.append("Camera Model: " + getExifTag(exif,ExifInterface.TAG_MODEL) + "\n");
builder.append("Camera Orientation: " + getExifTag(exif,ExifInterface.TAG_ORIENTATION) + "\n");
builder.append("Camera White Balance: " + getExifTag(exif,ExifInterface.TAG_WHITE_BALANCE) + "\n");
builder = null;
}
catch (IOException e)
{
e.printStackTrace();
}
}
We can get all the Exif tag information from picture in one builder string.
我们可以在一个构建器字符串中从图片中获取所有 Exif 标签信息。

You can use the ExifInterface class to read various EXIF metadata from JPEGs:
您可以使用 ExifInterface 类从 JPEG 中读取各种 EXIF 元数据：
