我尝试从URl安装apk,这是我的代码:

Intent promptInstall = new Intent(android.content.Intent.ACTION_VIEW);
promptInstall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
promptInstall.setDataAndType(Uri.parse("http://10.0.2.2:8081/MyAPPStore/apk/Teflouki.apk"), "application/vnd.android.package-archive" );

startActivity(promptInstall);

但我有这个问题:

05-10 15:09:29.511: ERROR/AndroidRuntime(1668): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=http://10.0.2.2:8081/MyAPPStore/apk/Teflouki.apk typ=application/vnd.android.package-archive flg=0x10000000 }
