具體程式碼實現片段是：

1. <pre name="code"class="java">Intent intent = new Intent(Intent.ACTION_VIEW);  
2. intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);   
3. intent.setDataAndType(Uri.fromFile(new File(filePath)),"application/vnd.android.package-archive");  
4. startActivity(intent);  

filePath是該檔案的絕對路徑。
