参考了这个里面的代码

一直报错

06-16 23:58:50.698 26148-26161/com.example.myapplication.app W/ContentResolver﹕ Failed to get type for: content://media/external/images/media/120818 (Unknown URL : content://media/external/images/media/120818)
06-16 23:58:50.708 26148-26161/com.example.myapplication.app W/Binder﹕ Caught a RuntimeException from the binder stub implementation.
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=content://media/external/images/media/120818 }

我自己的部分代码

  @Override
    public void onMediaScannerConnected() {
        Log.d("onMediaScannerConnected", "success  " + conn);
        Log.d("scanpath", "scanpath  " + scanpath);
        conn.scanFile(scanpath, "image/png");//主要是这里原本和上面的那个链接是一样的写成了"image/*" 然后各种报错，报找不到activity，其实可能是对于的格式自动匹配有问题，应用装了快播，竟然默认打开了快播，无力吐槽。最后更正，高了一个晚上
    }//媒体扫描

    @Override
    public void onScanCompleted(String s, Uri uri) {
        try {
            Log.d("onScanCompleted", uri + "success" + conn);
            System.out.println("URI " + uri);
            System.out.println("path" + path);
            if (uri != null) {
                Intent intent = new Intent(Intent.ACTION_VIEW);

                intent.setData(uri);

                Log.d("inten", "inten  " + intent.toString());
                startActivity(intent);
            }
        } finally {
            conn.disconnect();
            conn = null;
        }
    }//媒体扫描完毕
