我正在使用以下代码从特定目录打开图像..问题是它适用于我的银河王牌...但我无法在其他手机上打开它..我还附加了堆栈跟踪。请帮忙..谢谢你:)

private void startScan() {
        Log.d(Login.TAG, "Scan Started");
        if (conn != null) {
            conn.disconnect();
        }

        conn = new MediaScannerConnection(this, this);
        conn.connect();
    }

    public void onMediaScannerConnected() {
        conn.scanFile(SCAN_PATH, FILE_TYPE);
    }

    public void onScanCompleted(String path, Uri uri) {
        try {
            if (uri != null) {
                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setData(uri);
                startActivity(intent);
            }
        } finally {
            conn.disconnect();
            conn = null;
        }
    }

那是因为您的设备没有能够查看该本地文件的应用程序。尝试从 appStore 下载与查看图像相关的应用程序。

我正在参考您提供的 logcat 详细信息来回答这个问题。（可能是正确的答案，也可能不是正确的答案）

希望这可以帮助
