程序中的錯誤以編程方式在Android上安裝應用程序

Question

我使用此代碼以編程方式從我的應用程序安裝voice_search。

Intent promptInstall = new Intent(Intent.ACTION_VIEW) 
.setData(Uri.parse("file:///android_asset/voicesearch.x.apk")) .setType("application/vnd.android.package-archive"); 

我有這樣的錯誤

Answer 1

我有這個

Intent installIntent = new Intent(Intent.ACTION_VIEW); 
Uri apkFile = Uri.fromFile(myFile); 
installIntent.setDataAndType(apkFile, 
    "application/vnd.android.package-archive"); 

，並與一個apk文件的工作。可能會同時設置數據和類型？
