Android (SpreadTurm)无T卡下载文件导致无法释放手机内存

来源:互联网 发布:工位图 制作软件 编辑:程序博客网 时间:2024/04/28 12:27
SpreadTurm在无T卡情况下使用/data/internal_memory路径存储下载文件,在删除文件进行路径匹配时未包含此路径

增加此路径前缀匹配过程.

详细路径:packages\providers\DownloadProvider\ui\src\com\android\providers\downloads\ui\DownloadList.java

红色文字为增加匹配的代码

    private void deleteDownload(long downloadId) {
        if (moveToDownload(downloadId)) {
            int status = mDateSortedCursor.getInt(mStatusColumnId);
            boolean isComplete = status == DownloadManager.STATUS_SUCCESSFUL
                    || status == DownloadManager.STATUS_FAILED;
            String localUri = mDateSortedCursor.getString(mLocalUriColumnId);
            if (isComplete && localUri != null) {
                String path = Uri.parse(localUri).getPath();
                if (path.startsWith(Environment.getExternalStorageDirectory().getPath())
                        || path.startsWith(Environment.getDataDirectory().getPath())) {
                    String mediaProviderUri = mDateSortedCursor.getString(mMediaProviderUriId);
                    if (TextUtils.isEmpty(mediaProviderUri)) {
                        // downloads database doesn't have the mediaprovider_uri. It means
                        // this download occurred before mediaprovider_uri column existed
                        // in downloads table. Since MediaProvider needs the mediaprovider_uri to
                        // delete this download, just set the 'deleted' flag to 1 on this row
                        // in the database. DownloadService, upon seeing this flag set to 1, will
                        // re-scan the file and get the MediaProviderUri and then delete the file
                        mDownloadManager.markRowDeleted(downloadId);
                        return;
                    } else {
                        getContentResolver().delete(Uri.parse(mediaProviderUri), null, null);
                        // sometimes mediaprovider doesn't delete file from sdcard after deleting it
                        // from its db. delete it now
                        try {
                          File file = new File(path);
                          file.delete();
                      } catch (Exception e) {
                          Log.w(LOG_TAG, "file: '" + path + "' couldn't be deleted", e);
