如何在Android客戶端上觸發Adobe Reader安裝

Question

我知道這種類型的問題已經在SO上回答了很多次。但我無法找到符合我要求的答案。

我需要知道，如果是安裝在客戶端上的Adobe閱讀器爲Android。如果不觸發從應用程序中讀取器的安裝，然後查看PDF ...

我是那種在Android新手...用代碼表示讚賞流..

感謝ü..

嗨注：Kunal我已經寫了一些代碼，請你穿越驗證它，因爲我還沒有測試它

Answer 2

如果你想如果讀者沒有安裝你可以解僱這個意圖在您的活動鏈接到市場：

Intent marketIntent = new Intent(Intent.ACTION_VIEW) 
.setData(Uri.parse("market://details?id=com.adobe.reader")); 
startActivity(marketIntent); 

查看PDF是需要一些技巧：

Intent showPDFIntent = new Intent(); 
showPDFIntent.setPackage("com.adobe.reader"); 
showPDFIntent.setDataAndType(Uri.fromFile(myPDFFile), "application/pdf"); 
startActivity(showPDFIntent); 

我希望這有助於。

最良好的祝願， 添
