Android 使用ContentResolver获取手机图片和照片的相关信息

Uri mImageUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
ContentResolver mContentResolver = MainActivity.this.getContentResolver();

//只查询jpeg和png的图片
Cursor mCursor = mContentResolver.query(mImageUri, null,
MediaStore.Images.Media.MIME_TYPE + "=? or "
+ MediaStore.Images.Media.MIME_TYPE + "=?",
new String[]{"image/jpeg", "image/png"}, MediaStore.Images.Media.DATE_MODIFIED);

while (mCursor.moveToNext()) {
//获取图片的路径
String path = mCursor.getString(mCursor
.getColumnIndex(MediaStore.Images.Media.DATA));

Log.v("CB", path);
try {
ExifInterface exifInterface = new ExifInterface(path);
