Answer 2

if(有sd卡){
         request.setDestinationInExternalPublicDir(savePath, filename);//-->eg./storge/sdcard0/transuner/apks
 }else{
 }
。。
c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI))是这样的类型：content://downloads/my_downloads/15,调用以下方法：public static String getFilePathFromUri(Context c, Uri uri) {
    String filePath = null;
    if ("content".equals(uri.getScheme())) {
        String[] filePathColumn = { MediaColumns.DATA };
        ContentResolver contentResolver = c.getContentResolver();         Cursor cursor = contentResolver.query(uri, filePathColumn, null,
                null, null);         cursor.moveToFirst();         int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        filePath = cursor.getString(columnIndex);
        cursor.close();
    } else if ("file".equals(uri.getScheme())) {
        filePath = new File(uri.getPath()).getAbsolutePath();
    }
    Log.i(TAG, "filePath="+filePath);
    return filePath;
}getFilePathFromUri(Context c, Uri.parse(content://downloads/my_downloads/15))得到apk路径：String uriString = "dat=/data/data/com.android.providers.downloads/cache/xxx. apk"打开的时候要用：
intent.setDataAndType(Uri.fromFile(new File(uriString)), "application/vnd.android.package-archive");
而不能用
intent.setDataAndType(Uri.parse(uriString), "application/vnd.android.package-archive");
